Description:

This is an application which presents a hierarchy of settings applications.
It is used (among others) in the launcher's and filebrowser's settings-dialogs.

However, it is rather generic and can be setup for any application's setting dialog.
The actual contents (i.e. the organization tree and tab contents) is provided
by a spec-array (the settingsList).
You will find a default settings list here, but in theory, applications may provide
their own one, or modify a copy of that list for specialized settings dialogs.
See class >> examples, #defaultSettingsApplicationList
and AbstractLauncherApplication >> settingsList for more info.

not canceled

 currentSettingsFilename

JV@2012-02-07: Changed to save preferences back to file from which
they have been loaded (if known). If no such file is known,
save to DEFAULT USER SETTINGS file (default ~/.smalltalk/settings.rc)

 mainMenu

This resource specification was automatically generated
by the MenuEditor of ST/X.

 openWithList: settingsList label: label

 openWithList: settingsList label: label initialSettingsClass: settingsClassToSelectOrNil

given a list of page-label/class pairs,
open a settings dialog showing that set of items.

Instance protocol:

 requestor

return the 'requestor' of the SettingsDialog

 requestor: something

 rootItem

 rootItemLabel

 rootItemLabel: aString

 selectedItemsName

 showRoot: aBoolean

 subCanvasApplication

 changeLabelTo: aLabel application: aApplication

 destroyAll

 doIndicatorClick: index

handle a click on the indicator

 doReload

discard button was pressed

 doSave

accept button was pressed

 expandItemForApplication: aApplication

 help

 reopenLauncher

force the launcher to reopen an instance of itself.
Done whenever relevant look&feel settings are changed
(actually a workaround - a much better solution would be to teach
all smalltalk applications/views to dynamically update their style).

 sendLoadRequestToAll

ask all subApps to reload their idea of the current settings.
Do this, after userPrefs have been loaded from a file,
while a settingsDialog is open

 sendSaveRequestToAll

give all subapps a chance to apply any changes.
No longer needed, as we do this at the time the subApp
is changed; so only the current app needs this chance again,
when about to close (seesendSaveRequestToCurrent)

 sendSaveRequestToCurrent

when about to close the dialog, give the current
subapp a chance to apply any changes

 closeButtonVisibleHolder

 enableHelp

 enableOK

 enableReload

 loadAndSaveSettingsItemVisible

for now, only show these if I have a requestor
(i.e. I am a full settings Dialog as opposed to a DebugView, FileBrowser or other
settingsDialog. I think this has to be reworked...

usage example(s):

loadAndSaveSettingsItemVisible

 quickSearchFieldShownHolder

when the search box is opened, warp the focus into the field

 quickSearchStringHolder

 selectedItem

 showNonDefaultSettingsHolder

 showNonDefaultSettingsMenuItemVisibleHolder

 subCanvasApplicationHolder

 whyDisabledInfoHolder

 modifiedChanged

 selectionChanged

settings selection has changed;
first send the previous application a saveRequest;
then construct the new selected application (if not yet done before),
and set it in the right subcanvas

 update: something with: aParameter from: changedObject

 highlightWidgetsWithChangedSettings

whenever an app is selected AND a quick search string is present,
go through the widgets and highlight those which match.
This is done by looking at the helpkey and model aspects for a match

 showNonDefaultSettingsHolderChanged

the show-non-default settings check box has changed.
remember the current selection,
update the highlighting of matching fields (and expand corresponding tree nodes),
then reselect (because the treeView is too stupid in loosing the selection,
when expanding/hiding)

 widgetsWithChangedSettingsIn: anApplication

helper:
go through the widgets and find those which have a value different
from the default settings.
This is done by looking at model value (hope they have)

 closeRequest

This is a hook method.
It will be invoked when your app/dialog-window is about to be closed.
This method has a chance to suppress the close by returning false.
See also #closeDownViews, which is invoked when the close is really done.

 createRootItem

this is stupidly wrong!

 initialize

false

 postBuildSubCanvas: aWidget

 postBuildWith: aBuilder

 postOpenWith: aBuilder

if there is only one child, select it initially

 askForFileAndSaveSettings

 loadSettingsFromFile

 saveSettingsWithoutAskingForFile

 reopenAfterChangedViewStyleSetting

open the dialog. Take care to redefine some superclass behavior

 getWordMatchPattern

pattern is needed at multiple places

 getWordMatchPatterns

patterns are needed at multiple places

 highlightApplicationsForWhich: aBlock

common code for string search and changed-settings search.
Enumerates all applications with aBlock;
if it return true, it will be collectet and highlighted.

 highlightWidgets: aSetOfWidget

highlight a matching widget

 highlightWidgetsWithMatchingSearchString

whenever an app is selected AND a quick search string is present,
go through the widgets and highlight those which match.
This is done by looking at the helpkey and model aspects for a match

 quickSearchStringHolderChanged

the text in the quick search entry field has changed.
remember the current selection,
update the highlighting of matching fields (and expand corresponding tree nodes),
then reselect (because the treeView is too stupid in loosing the selection,
when expanding/hiding)

 unhighlightFoundItemsFromSearch

undo any highlighting of matching fields (from the previous show matching items)

 unhighlightWidgets

unhighlight all previously highligted widgets
(restore their previous attributes)

 widgetsWithMatchingSearchStringIn: anApplication

helper:
