Class protocol:

 updateStyleCache

(comment from inherited method)
this method gets some heavily used style stuff and keeps
it in class-variables for faster access.
Subclasses should redefine this to load any cached style-values
into faster class variables as well. These should NOT do a
super updateStyleCache, since this method is called for all view-classes
anyway.

Instance protocol:

 compareAction

 compareAction: something

 menuHolder: aValueThing

 setTextView: aTextView

self backgroundPaint: textView backgroundPaint darkened lighter.

 setTextViewScroller: aScr

 showLineNumbers: aBoolean

can be used to turn off linenumber drawing,
in case the gutter is used with another view anf only the other features (breakpoints) are needed

 acceptButtonBottom

 acceptCancelRight

 cancelButtonBottom

 computePreferredExtent

(comment from inherited method)
return my computed preferred extent - this is the minimum size I would like to have.
If there are any components, a rectangle enclosing them
is returned. Otherwise, the actual extent is returned.

Here, return a hooked on menu, but usually redefined to provide a widget-specific
menu.

return/create the 'currentBlockNodeHolder' value holder (automatically generated)

 currentBlockNodeHolder: something

set the 'currentBlockNodeHolder' value holder (automatically generated)

 adjustSizeForLongestLine

recompute the required width (longest linenumber present, not shown)

** This is an obsolete interface - do not use it (it may vanish in future versions) **

 adjustSizeForLongestLineNumber

recompute the required width (longest linenumber present, not shown)

 update: something with: aParameter from: changedObject

false

 buttonMultiPress: btn x: x y: y

extraSafeArea

 buttonPress: btn x: x y: y

(comment from inherited method)
button was pressed - check my components for a hit.

 mouseWheelMotion: buttonState x: x y: y amount: amount deltaTime: dTime

forward to my text view

 nonMultiButtonPress: btn x: x y: y

this is now called delayed for a single button press
(i.e. if there is no other click within some time)

 sizeChanged: how from: oldExtentOrNil

my view has changed the size (not the contents)

 helpTextAt: aPointOrNil

which service has an annotation for that line
