Description:

this class implements the common behavior of dialogboxes.

DialogBox is also a superclass of many other boxes - see InfoBox,
WarningBox, YesNoBox etc. for concrete examples.
Most of them simply add buttons or other elements.

For programmatically created boxes, instances support adding of components
in a top-to-bottom fashion, and also keep track of added text-fields and,
since they are most common, automatically create an EnterFieldGroup for
them.

Caveat:
    more adding support is required - especially for row-wise construction.
    The programmatic interface is best suited for row-wise
    arranged components; laying out elements in columns is a bit
    complicate - for complicated dialogs, it may be better to not use
    the automatic arrangement, but instead give explicit layouts to
    the components (in a subclass) or better use the UIPainter.

Compatibility note:
    For ST-80 compatibility, DialogBox is also accessible under
    the global named 'Dialog' (which is the name of an ST-80 class,
    providing a very similar protocol).
    This may lead to confusion, if DialogBox is recompiled - you have
    to manually assign Dialog again to refer to the new DialogBox class.
    In future versions of ST/X, DialogBox may be renamed to Dialog.

Historic note:
    originally, ST/X had separate classes for the various entry methods;
    there were YesNoBox, EnterBox, InfoBox and so on.
    ST-80 has all this defined in the common Dialog.
    Therefore, for compatibility, many ST/X methods defined here in Dialogs
    class protocol simply dispatch to some other boxes class method.
    In the future, those existing subclasses' functionality is going to
    be moved full into Dialog, and the subclasses will be replaced by dummy
    delegators. (They will be kept for backward compatibility, though).


[instance variables:]

    buttonPanel      <PanelView>    contains the button(s)

    okButton         <Button>       the ok-Button

    okAction         <Block>        the action to be performed when ok is pressed,
                                    or return is pressed.

    acceptReturnAsOK <Boolean>      if true, pressing the return-key counts
                                    as if ok was pressed. Default is true.

    abortButton      <Button>       the cancel-Button

    abortAction      <Block>        the action to be performed when cancel is
                                    pressed.

    yPosition        <Integer>      current y position when adding components

    leftIndent       <Integer>      left inset to use when adding components

    rightIndent      <Integer>      right inset to use when adding components

    addedComponents  <Collection>   programmatically added components

    inputFieldGroup  <EnterFieldGroup>
                                    for added input fields

    acceptOnLeave    <Boolean>      if true (the default) and there are
                                    tabable inputFields, accept and close when
                                    the last field is left. If false, the ok
                                    button must be pressed to close the box.

    acceptedValue    v(<Boolean>)   valueHolder on a boolean
                                    after close: holds true if box was accepted
                                    (i.e. ok-Button was pressed), false if box was
                                    closed via cancel or window manager.

    autoAccept       Boolean        if true, pressing ok (or return)
                                    sends #accept to all subcomponents.
                                    I.e. all subfields update their models
                                    first. The default is true.

    variablePanel   nil|VPanel      an optional additional panel to be filled dynamically
                                    in an aboutToOpenNotification hook.

For compatibility with ST-80, this class is also available under
the global names DialogView and Dialog (see patches file).

inputFocusa DialogBox with multiple input fields can be configured on how it
shall behave if the RETURN key is pressed. 

The default is to shift the focus to the ok-button - thus, another return
has to be entered (as confirmation) to close & accept the box.

This can be changed to force an automatic OK with:
    aBox focusToOKOnLeave:false

Then, leaving the last field with return, automatically accepts the box,
as if ok was pressed. (useful for simple - single entry dialogs).
All simple dialogs (like 'enter a searchString') behave this way.


With: 
    aBox acceptReturnAsOK:false

any focusShift or automatic OK is turned off, and the input group 
switches its focus back to the topMost field. 
The default for this is true.
(useful, if you want an explicit ok from the user, or need all fields
 to be handled somehow).


Simply leaving the group with a cursor movement may also be either
interpreted as a return (the default), or again wrap back to the top
of the group.

With:
    aBox acceptOnLeave:false
this is turned off, so that with cursor-down, the focus is moved back 
to the first entry field. The default is true.

Class protocol:

Compatibility-Squeak

chooseDirectory: self chooseDirectory

Compatibility-VW

choose: aString fromList: list values: listValues lines: maxLines cancel: cancelBlock for: aView

launch a Dialog showing the message and list.
The user can select an item and click ok; in this case, the corresponding value
from listValues is returned (doubleclick works as well).
If cancel is pressed, the value of cancelBlock is returned.
Pressing ok without a selection is treated like cancel.
This is a new VW2.5 interface - passing an addtional argument.
In ST/X, this is not needed and ignored

Usage example(s):

     Transcript showCR:(
	 Dialog 
	    choose:'choose any' 
	    fromList:#('one' 'two' 'three' 'four') 
	    values:#(1 2 3 4) 
	    lines:4
	    cancel:nil
     )

     Transcript showCR:(
	 Dialog 
	    choose:'choose example' 
	    fromList:#('one' 'two' 'three' 'four') 
	    values:#(1 2 3 4) 
	    lines:4
	    cancel:[Transcript flash. #aborted]
     )

on the fly modifications

modifyingBoxWith: modifyBlock do: openingBlock

perform openingBlock (which usually creates a standard dialog box),
but call modifyBlock right before the dialog is actually opened.
This allows modifyBlock to add additional controls to the dialog.
ModifyBlock is called with the box as argument.

Instance protocol:

accessing-behavior

abortAction: aBlock: define the action to be performed when abort is pressed
acceptCheck: aBlock: if nonNil, the acceptCheck-block is evaluated when the dialog is
accepted (ok-button or Return-key). If it returns true, the box is closed,
otherwise not. Of course, you may also use a valueHolder instead of a block
to provide the check value.
acceptOnLeave: aBoolean: define the behavior when the last input field is left via cursor keys.
The default is to accept & close the dialog (i.e. true).
acceptReturnAsOK: aBoolean: turn on/off interpretation of return-key as ok.
Default is on
action: aBlock: set the action to be performed when user presses ok-button;
aBlock must be nil or a block. This method simply
reuses okAction: and has been added for a consistent action-setting
protocol.
focusOnField: anInputField: arrange for the argument to get the focus (initially)
focusToOKOnLeave: aBoolean: define the behavior when the last input field is left via a return
or cursor key.
The default is to shift the focus to the OK button (i.e. true).
If turned off, the OK is immediately performed, i.e.
the dialog is accepted & closed.
hideOnAccept: aBoolean: control if the dialog should close when accepted.
The default is true
makeTabable: aComponentOrSubcomponent: add a component (usually a subcomponent, of which the dialog
does not know) to the list of tabable ones (i.e. those, that can be
stepped through via FocusNext/FocusPrevious).
Toplevel tabable components are usually added with #addComponent:tabable:
makeTabable: aComponentOrSubcomponent after: anotherComponent: add a component (usually a subcomponent, of which the dialog
does not know) to the list of tabable ones (i.e. those, that can be
stepped through via FocusNext/FocusPrevious).
Toplevel tabable components are usually added with #addComponent:tabable:

** This is an obsolete interface - do not use it (it may vanish in future versions) **
makeUntabable: aComponentOrSubcomponent: (tabableElements includesIdentical:aComponentOrSubcomponent) ifFalse:[
noAction: aBlock: define the action to be performed when 'no' is pressed
okAction: aBlock: define the action to be performed when ok is pressed
title: aString yesAction: yesBlock noAction: noBlock: define title and actions
yesAction: aBlock: define the action to be performed when 'yes' is pressed
yesAction: yesBlock noAction: noBlock: define both actions

accessing-channels

acceptChannel: same as #accept: return the valueHolder which is set to true when the box
is accepted
acceptChannel: aValueHolder: set the valueHolder which is set to true when the box
is accepted

accessing-components

abortButton

return the abortButton - this access is provided to allow
setting the buttons look (for example: colors or font)

buttonPanel

return the buttonPanel - this access is provided to allow
setting the buttons look (for example: colors or font),
and/or to add buttons on the fly via the modifyingBox:do: hook

cancelButton

same as #abortButton;
return the abortButton - this access is provided to allow
setting the buttons look (for example: colors or font)

noButton

return the no-button

okButton

return the okButton - this access is provided to allow
setting the buttons look (for example: colors or font)

verticalPanel

if there is none yet, create and add a vertical panel.
This can be used to add additional components in
an aboutToOpen hook callback (or via the modifyingBox:do: hook).

Usage example(s):

verticalPanel height:25.

verticalPanelIfPresent

yesButton

return the 'yes'-button

accessing-elements

componentAt: name: retrieve a component by name - to access it, it must have been
named previously with #name:as:
name: element as: name: assign a name to a component. This can be done during construction,
to allow later access to the components (i.e. without a need to
remember them in some instVars)

accessing-look

abortText: aString

define the label in the abort-button

hideButtons

hides the buttonPanel (i.e. the ok and cancel buttons if any)

noLabel: aString

define the label of the 'no'-button.
And alias for #noText: - for backward compatibility

noText: aString

define the label of the no-button.
If not set, it defaults to the resource-string for 'no'.

okText: aString

define the text in the ok-button

okText: okString abortText: abortString

set both texts displayed in the buttons

okText: yesString noText: noString

define the labels of both buttons.
Alias for yesText:noText: for backward compatibility.

title: aString

define title

     (DialogBox new title:'Foo') open

title: aString yesText: yesString noText: noString

define title and button labels

yesLabel: aString

define the label of the 'yes'-button.
An alias for #yesText: for backward compatibility.

yesText: aString

define the label of the 'yes'-button

yesText: yesString noText: noString

define the labels of both buttons

explicit focus control

focusOnOk

initialization & release

defaultExtent: redefined to return my last extent
as default for the open
initialize: must be called if redefined
reAdjustGeometry: sent late in snapin processing - gives me a chance
to resize for changed font dimensions.
rememberLastExtent: can be redefined in subclasses to return true
iff the default size should be the same as the size when last closed.
If false is returned, the default size is computed from the contents.
Remembering is useful for file-selection boxes,
when the user resized the box for many files.
It is NOT useful for generic box (like information:) which should just
adopt to their contents.
Here, false is returned as default, because I am abstract, not knowing what is
shown in me.

layout control

bottomAlign: widgets

mhmh - seems similar to our stickAtBottom functionality - to be checked

bottomAlignLowerEdge: widget

mhmh - seems similar to our stickAtBottom functionality - to be checked

leftIndent

return the current indent
(current x position - that's where the next component will be positioned).

leftIndent: aNumber

set the left indent
(current x position - that's where the next component(s) will be located).
Setting this before adding a component will place it indented

Usage example(s):

     |dialog|

     dialog := DialogBox new.
     (dialog addTextLabel:'label1') adjust:#left.
     dialog leftIndent:20.
     (dialog addTextLabel:'label2') adjust:#left.
     dialog leftIndent:40.

     dialog leftIndent:60.
     (dialog addTextLabel:'label4') adjust:#left.

     dialog addOkButton.
     dialog open.

rightIndent

return the current right indent.

rightIndent: aNumber

set the right indent

Usage example(s):

     |dialog|

     dialog := DialogBox new.
     (dialog addTextLabel:'label1') adjust:#right.
     dialog rightIndent:20.
     (dialog addTextLabel:'label2') adjust:#right.
     dialog rightIndent:40.
     (dialog addTextLabel:'label3') adjust:#right.

     (dialog addTextLabel:'label4') adjust:#right.

     dialog addOkButton.
     dialog open.

setInitialGap

stickAtBottomWithFixHeight: aComponent

arrange for a component to be positioned at a constant offset
from the bottom of the box and its height to remain the same.
This will keep the component at a constant distance from the bottom
(without this setup, it would stay at a constant offset from the top).
ATTENTION: use this as a last step, after all components have been added.

stickAtBottomWithFixHeight: aComponent left: left right: right

stickAtBottomWithVariableHeight: aComponent

arrange for a component to be positioned at a constant offset
from the bottom of the box and its height to be adjusted.
This will resize the component for a constant distance from the top,
and the bottom.
(without this setup, its height would remain constant).
ATTENTION: use this as a last step, after all components have been added.

yPosition

return the current y position
(that's where the next component will be positioned).

yPosition: aNumber

set the current y position
(that's where the next component will be positioned).

Usage example(s):

     |dialog pos|

     dialog := DialogBox new.
     pos := dialog yPosition.
     (dialog addTextLabel:'label1') width:0.5.
     dialog yPosition:pos.
     (dialog addTextLabel:'label2') width:0.5; left:0.5.

private

assignKeyboardFocusToFirstKeyboardConsumer: disabled - the focus might have already been changed
basicAddComponent: aComponent: add a component, don't change its size
forceResize: force a recomputation of my size.
Call this, when elements were added to a subcomponent,
of which I cannot know.
Eg. when someone gets the buttonPanel or the verticalPanel and adds an element to it
hideAndEvaluate: aBlock: if I am modal, make myself invisible and evaluate aBlock.
If nonModal, stay up, but also evaluate the block.
preOpen
realize: if any inputFields were added, activate the first one
resize: verticalPanel notNil ifTrue:[

queries

accepted: after the box has closed:
return true if accepted, false if canceled
canceled: after the box has closed:
return true if canceled, false if accepted
computePreferredExtent: return my preferred extent.
That is the max component width, or my current width (default);
whichever is larger, by the sum of the component's heights.
interfaceSpecFor: aSelector: return an interface spec.
Notice - Dialog should be moved under AppModel so this becomes obsolete.
maxPreferredWidthOfAddedComponents: helper for computing my preferred extent.
That is the max component width
positionOffset: return the delta, by which the box should be displayed
from the mouse pointer. Here, an offset is returned, which
makes the center of the first return-Button in the panel
appear under the cursor. If there is no such button,
use my superclasses offset.
specificationFor: aKey: return an interface spec's literal encoding.
Notice - Dialog should be moved under AppModel so this becomes obsolete.

testing

isDialogBox: (comment from inherited method)
answer true, if my view represents a Dialog

user actions

abortPressed: sent by the cancel button; user pressed abort button
- hide myself and evaluate okAction
actionArgument
closeCancel: closed via escape
doAccept: let all components accept (i.e. update their model from the values),
then set my accept value to true.
This is confusing: this method was originally called #accept,
but renamed for compatibility with ST-80, where #accept returns the
accept-valueHolder (which looks like a bad name to me ...).
handlesKeyPress: key inView: view: delegated
hide: redefined to remember my last extent;
used as default for the next open
keyPress: aKey x: x y: y: return-key duplicates ok-function if acceptReturnAsOK is true
keyPress: aKey x: x y: y view: someView: delegated
lastFieldLeft: if the dialog involves input fields, this is called
when the last field is left by Return-key or NextField-key
okPressed: sent by the okButton; user pressed ok-button
- make myself invisible and if an action was specified, then do it
openDialog: open the dialog modal; then return true if accepted, false if canceled

Examples:

historically, DialogBox was used as an abstract class as a base for InfoBox, YesNoBox etc. However, the programmatic construction protocol (#addComponent:) now allows those classes to be easily replaced and future versions of ST/X may do this and make those subclasses obsolete. However, dummy stubs will remain to exist for backward compatibility (i.e. do not fear using YesNoBox, EnterBox etc.) For most simple standard dialogs, there are ready to use methods in the class protocol. For example: info & warnings:

    Dialog information:'hi there'

    Dialog warn:'oops'

yes/no questions:

    (Dialog confirm:'is this simple ?')
    ifTrue:[
        Transcript showCR:'thats what I expected'
    ] ifFalse:[
        Transcript showCR:'read more examples and documentation'
    ]

yes/no question with cancel option:

    |answer|

    answer := Dialog confirmWithCancel:'is this simple ?'.
    answer isNil ifTrue:[
        Transcript showCR:'no easy decision'
    ] ifFalse:[
        answer ifTrue:[
            Transcript showCR:'thats what I expected'
        ] ifFalse:[
            Transcript showCR:'read more examples and documentation'
        ]
    ]

asking for a string:

    |s|

    s := Dialog request:'enter your name, please:'.
    s notEmpty ifTrue:[
        Transcript showCR:'you entered: ' , s.
    ]

asking for a string with given default:

    |s|

    s := Dialog 
            request:'enter your name, please:'
            initialAnswer:(OperatingSystem getLoginName).
    s notEmpty ifTrue:[
        Transcript showCR:'you entered: ' , s.
    ]

asking for a filename:

    |s|

    s := Dialog 
            requestFileName:'select a file, please:'
            default:''.
    Transcript show:'you entered: '; showCR:s.

with a namefiler pattern:

    |s|

    s := Dialog 
            requestFileName:'select a file, please:'
            default:''
            pattern:'*.rc'.
    Transcript show:'you entered: '; showCR:s.

another namefiler pattern:

    |s|

    s := Dialog 
            requestFileName:'select a file, please:'
            default:''
            pattern:'*.rc;*.st;*.h'.
    Transcript show:'you entered: '; showCR:s.

with changed button label and pattern:

    |s|

    s := Dialog 
            requestFileName:'select a file, please:'
            default:''
            ok:'show'
            abort:'cancel'
            pattern:'*.rc'.
    Transcript show:'you entered: '; showCR:s.

asking for a password:

    |s|

    s := Dialog 
            requestPassword:'enter your secret, please:'.
    Transcript show:'you entered: '; showCR:s.

multiple choice dialogs:

    Dialog 
       choose:'choose any' 
       fromList:nil
       values:nil
       buttons:#('one' 'two' 'three' 'four') 
       values:#(1 2 3 4) 
       lines:nil
       cancel:nil

multiple choice dialog, with list & buttons:

     Transcript showCR:(
         Dialog 
            choose:'choose example' 
            fromList:#('one' 'two' 'three' 'four') 
            values:#(1 2 3 4) 
            buttons:#('five' 'six' 'seven')
            values:#(5 6 7)
            lines:4
            cancel:[Transcript flash. #aborted]
     )

You can (and often have to) construct custom dialogs programmatically, from individual components. As shown in the following examples: basic (unusable) example:

    DialogBox new open

still unusable - only an ok-button:

    DialogBox new addOkButton; open

both ok- and abortButtons:

    DialogBox new addAbortButton; addOkButton; open

with different ok-label:

    DialogBox new addAbortButton; addOkButtonLabelled:'yeah'; open

adding a (centered by default) textlabel gives an infoBox:

    DialogBox new
        addTextLabel:'hello';
        addOkButton; 
        open

a textlabel with abort- and okButton gives a yesNoBox:

    DialogBox new
        addTextLabel:'hello';
        addAbortButton; 
        addOkButton; 
        open

the same, adjusting the label's contents to the left:

    |box|

    box := DialogBox new.
    (box addTextLabel:'hello') adjust:#left.
    box addAbortButton; 
        addOkButton; 
        open

with modified buttons:

    |box|

    box := DialogBox new.
    (box addTextLabel:'are you certain ?') adjust:#left.
    box addAbortButtonLabelled:'not really'. 
    (box addOkButtonLabelled:'yes, absolutely') 
            activeBackgroundColor:Color red. 
    box open

mswindows style (different up/down bitmaps in buttons): ((try tabbing ...)

    |b box|

    box := DialogBox new.
    (box addTextLabel:'are you certain ?') adjust:#left.
    b := Button new.
    b activeLogo:(Image fromFile:'cancel_down.bmp' inPackage:'stx:goodies/bitmaps/winImages').
    b passiveLogo:(Image fromFile:'cancel_up.bmp' inPackage:'stx:goodies/bitmaps/winImages').
    b focusLogo:(Image fromFile:'cancel_focus.bmp' inPackage:'stx:goodies/bitmaps/winImages').
    b beImageButton.
    box addAbortButton:b.

    b := Button new.
    b activeLogo:(Image fromFile:'ok_down.bmp' inPackage:'stx:goodies/bitmaps/winImages').
    b passiveLogo:(Image fromFile:'ok_up.bmp' inPackage:'stx:goodies/bitmaps/winImages').
    b focusLogo:(Image fromFile:'ok_focus.bmp' inPackage:'stx:goodies/bitmaps/winImages').
    b beImageButton.
    box addOkButton:b.
    box open

two textlabels:

    DialogBox new
        addTextLabel:'hello';
        addTextLabel:'world';
        addAbortButton; 
        addOkButton; 
        open

fixing the dialog's size (suppress it calculating its size from the preferredExtents of its components):

    DialogBox new
        label:'a simple dialog';
        addTextLabel:'hello';
        addAbortButton; 
        addOkButton; 
        extent:200@200;
        sizeFixed:true;
        open

asking the box if it was closed via ok:

    (DialogBox new
        label:'a simple dialog';
        addTextLabel:'hello';
        addAbortButton; 
        addOkButton; 
        extent:200@200;
        sizeFixed:true;
        open
    ) accepted ifTrue:[
        Transcript showCR:'yes'
    ] ifFalse:[
        Transcript showCR:'no'
    ]

textLabels are not limited to strings (although, the name which is used for ST-80 compatibility, suggests it):

    DialogBox new
        addTextLabel:(Image fromFile:'garfield.gif' inPackage:'stx:goodies/bitmaps/gifImages');
        addOkButton; 
        open

    DialogBox new
        addTextLabel:'hello';
        addTextLabel:((Image fromFile:'garfield.gif' inPackage:'stx:goodies/bitmaps/gifImages')
                            magnifiedTo:200@150);
        addTextLabel:'world';
        addAbortButton; 
        addOkButton; 
        open

adding an input field (on a string model):

    |stringModel|

    stringModel := '' asValue.
    (DialogBox new
        addTextLabel:'Please enter a string:';
        addInputFieldOn:stringModel; 
        addAbortButton; 
        addOkButton; 
        open
    ) accepted ifTrue:[
        Transcript showCR:'entered: ', stringModel value
    ]

multiple input fields (notice, that the dialog connects the fields in a group, so stepping is allowed via Cursor and Return keys):

    |firstName lastName|

    firstName := '' asValue.
    lastName := '' asValue.
    (DialogBox new
        addTextLabel:'Please enter your name:';
        addInputFieldOn:firstName; 
        addVerticalSpace;
        addInputFieldOn:lastName; 
        addAbortButton; 
        addOkButton; 
        open
    ) accepted ifTrue:[
        Transcript showCR:'entered: ', firstName value , ' ' , lastName value
    ]

of course, the model may contain a value initially:

    |firstName lastName p line i name|

    firstName := '' asValue.
    lastName := '' asValue.
    p := PipeStream readingFrom:'finger ' , OperatingSystem getLoginName.
    p notNil ifTrue:[
        line := p nextLine.
        (i := line findString:'Name:') ~~ 0 ifTrue:[
            name := line copyFrom:(i + 'Name:' size).
        ] ifFalse:[
            (i := line findString:'real life:') == 0 ifTrue:[
                line := p nextLine.
            ].
            (i := line findString:'real life:') ~~ 0 ifTrue:[
                name := line copyFrom:(i + 'real life:' size).
            ]
        ].
        name notNil ifTrue:[
            firstName value: name asCollectionOfWords first.
            lastName  value: name asCollectionOfWords last.
            Transcript showCR:'initially ' , firstName value , ' ' , lastName value.
        ].
        p close.
    ].

    (DialogBox new
        addTextLabel:'Please enter your name:';
        addInputFieldOn:firstName; 
        addVerticalSpace;
        addInputFieldOn:lastName; 
        addAbortButton; 
        addOkButton;
        open
    ) accepted ifTrue:[
        Transcript showCR:'entered: ', firstName value , ' ' , lastName value
    ]

validated password entry:

    |box firstEntry secondEntry|

    firstEntry := '' asValue.
    secondEntry := '' asValue.

    box := DialogBox new.
    (box addTextLabel:'Please enter your secret:') adjust:#left.
    (box addInputFieldOn:firstEntry) passwordCharacter:$*. 
    box addVerticalSpace.
    (box addInputFieldOn:secondEntry) passwordCharacter:$*. 
    box addAbortButton. 
    box addOkButton. 
    box open.
    box accepted ifTrue:[
        firstEntry value ~= secondEntry value ifTrue:[
            Transcript showCR:'wrong input - try again'
        ] ifFalse:[
            Transcript showCR:'entered: ', firstEntry value
        ]
    ]

input fields with a label:

    |box firstNameHolder middleNameHolder lastNameHolder|

    firstNameHolder := 'John' asValue.
    middleNameHolder := 'F' asValue.
    lastNameHolder := 'Peters' asValue.

    box := DialogBox new.
    box 
        addLabelledInputField:'first name:'
        adjust:#right
        on:firstNameHolder
        tabable:true
        separateAtX:0.4.

    box 
        addLabelledInputField:'middle initial:'
        adjust:#right
        on:middleNameHolder
        tabable:true
        separateAtX:0.4.

    box 
        addLabelledInputField:'last name:'
        adjust:#right
        on:lastNameHolder
        tabable:true
        separateAtX:0.4.

    box addOkButton.
    box open.

constructing a dialog from other elements: adding a fileSelectionList: (since the dialog adds the component with its preferred extent, ignoring the 300-height, this looks ugly ... ... especially when resized vertically)

    |top l scr fileName|

    fileName := '' asValue.

    top := DialogBox new.

    l := FileSelectionList new.
    l useIndex:false.
    l doubleClickAction:[:name | top okPressed].
    l action:[:name | fileName value:name].
    scr := ScrollableView forView:l.
    scr extent:(1.0 @ 300).

    top addComponent:scr.
    top addAbortButton; addOkButton.
    top openModal.

    top accepted ifTrue:[
        Transcript show:'fileName: '; showCR:fileName value storeString.
    ]

same, looks better, since the height is made larger (not using fileLists preferredExtent):

    |top l scr fileName|

    fileName := '' asValue.

    top := DialogBox new.

    l := FileSelectionList new.
    l useIndex:false.
    l doubleClickAction:[:name | top okPressed].
    l action:[:name | fileName value:name].
    scr := ScrollableView forView:l.

    top addComponent:scr withExtent:300@300.
    top addAbortButton; addOkButton.
    top openModal.

    top accepted ifTrue:[
        Transcript show:'fileName: '; showCR:fileName value storeString.
    ]

again, setting the boxes initial size and fixing it (let it ignore the components' preferredExtent):

    |top fixFrame l scr fileName|

    fileName := '' asValue.

    top := DialogBox new.
    top extent:300@300.

    fixFrame := View new.
    fixFrame extent:(1.0 @ 300).

    l := FileSelectionList new.
    l useIndex:false.
    l doubleClickAction:[:name | top okPressed].
    l action:[:name | fileName value:name].
    scr := ScrollableView forView:l.
    scr origin:0.0@0.0 corner:1.0@1.0.
    fixFrame add:scr.

    top addComponent:fixFrame.
    top addAbortButton; addOkButton.
    top openModal.

    top accepted ifTrue:[
        Transcript show:'fileName: '; showCR:fileName value storeString.
    ]

adding a panel with checkBoxes:

    |top panel b value1 value2 value3 value4|

    value1 := true asValue.
    value2 := false asValue.
    value3 := false asValue.
    value4 := true asValue.

    top := DialogBox new.
    top extent:200@300.

    panel := VerticalPanelView new.

    b := CheckBox on:value1. b label:'check1'.
    panel addSubView:b.

    b := CheckBox on:value2. b label:'check2'.
    panel addSubView:b.

    b := CheckBox on:value3. b label:'check3'.
    panel addSubView:b.

    b := CheckBox on:value4. b label:'check4'.
    panel addSubView:b.

    top addComponent:panel.
    top addAbortButton; addOkButton.
    top open.

    top accepted ifTrue:[
        Transcript show:'value1: '; showCR:value1 value.
        Transcript show:'value2: '; showCR:value2 value.
        Transcript show:'value3: '; showCR:value3 value.
        Transcript show:'value4: '; showCR:value4 value.
    ]

same, using a more convenient interface:

    |box value1 value2 value3 value4|

    value1 := true asValue.
    value2 := false asValue.
    value3 := false asValue.
    value4 := true asValue.

    box := DialogBox new.
    box extent:200@300.

    box addCheckBox:'check1' on:value1.
    box addVerticalSpace.
    box addCheckBox:'check2' on:value2.
    box addVerticalSpace.
    box addCheckBox:'check3' on:value3.
    box addVerticalSpace.
    box addCheckBox:'check4' on:value4.

    box addAbortButton; addOkButton.
    box open.

    box accepted ifTrue:[
        Transcript show:'value1: '; showCR:value1 value.
        Transcript show:'value2: '; showCR:value2 value.
        Transcript show:'value3: '; showCR:value3 value.
        Transcript show:'value4: '; showCR:value4 value.
    ]

same, using an even better interface:

    |box values labels|

    values := #(true false false true) collect:[:val | val asValue].
    labels := #('check1' 'check2' 'check3' 'check4').

    box := Dialog new.

    box
       addColumn:(1 to:labels size)
       fromX:0.0
       toX:1.0 
       collect:[:index | CheckBox label:(labels at:index) model:(values at:index)]
       tabable:true.
    
    box addAbortButton; addOkButton.
    box open.

    box accepted ifTrue:[
       values with:labels do:[:val :lbl |
          Transcript show:(lbl , ': '); showCR:val value.
       ]
    ]

adding two panels in a frame:

    |box frame vPanel1 vPanel2 m1 m2 m3 m4 chk ef|

    box := Dialog new.
    box label:'example'.

    frame := FramedBox label:'frame'.

    vPanel1 := VerticalPanelView origin:0.0@0.0 corner:0.5@1.0 in:frame.
    vPanel1 horizontalLayout:#leftSpace.
    vPanel1 verticalLayout:#spreadSpace.

    vPanel2 := VerticalPanelView origin:0.5@0.0 corner:1.0@1.0 in:frame.
    vPanel2 horizontalLayout:#leftSpace.
    vPanel2 verticalLayout:#spreadSpace.

    m1 := true asValue.
    m2 := true asValue.
    m3 := true asValue.
    m4 := 'hello' asValue.

    vPanel1 add:(Label label:'check1').
    vPanel1 add:(Label label:'m2').
    vPanel1 add:(Label label:'m3').
    vPanel1 add:(Label label:'enter').
    vPanel1 add:(Label label:'lbl1').
    vPanel1 add:(Label label:'lbl2').

    vPanel2 add:(chk := CheckToggle on:m1). 
    box makeTabable:chk.

    vPanel2 add:(chk := CheckToggle on:m2). 
    box makeTabable:chk.

    vPanel2 add:(chk := CheckToggle on:m3). 
    box makeTabable:chk.

    vPanel2 add:(chk := CheckToggle on:m3). 
    box makeTabable:chk.

    vPanel2 add:(chk := CheckToggle on:m3). 
    box makeTabable:chk.

    vPanel2 add:(ef := EditField on:m4). 
    ef immediateAccept:true.
    box makeTabable:ef.

    box addComponent:frame.

    box addAbortButton; addOkButton.
    box openModal.
    box accepted ifTrue:[
        Transcript showCR:'accepted with:'.
        Transcript showCR:'   m1: ' , m1 value printString.
        Transcript showCR:'   m2: ' , m2 value printString.
        Transcript showCR:'   m3: ' , m3 value printString.
        Transcript showCR:'   m4: ' , m4 value printString.
