TextCollectorView isEnabled

Hello forum.
VisualWorks does not display "the correct cursor", if the mouse moves over a text editor or an input field. Maybe this is a setting. I don't know.
What I did to make this work: First I have create a new "text marker cursor" in the Cursor class, plus its accessing method #textMarker.

TextMarkerCursor := (self
imageArray: #(
2r0000111011110000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000111011110000)
maskArray: #(
2r0000111011110000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000000100000000
2r0000111011110000)
hotSpot: 7@8 name: 'textMarker').

Then I have added the following methods in the TextEditorController:

enterEvent: anEvent
self view isEnabled ifTrue: [Cursor textMarker show].
^super enterEvent: anEvent

exitEvent: anEvent
Cursor currentCursor = Cursor textMarker ifTrue: [Cursor normal show].
^super exitEvent: anEvent

Finished.

What makes me mad is the fact, that both the TextCollectorView (Transcript) and the TextEditorView are used by the controller class TextEditorController.
The TextCollectorView does not implement the method #isEnabled. What causes an exception, if the mouse moves over the transcript window.
Now I like to implement the method #isEnabled for the class TextCollectorView. How is the correct way to do that? I do not see a state value or an enable flag or something like that.
Or is there an another procedure?

Best regards,
Tom Grünewald

Hi Tom,

Now I like to implement the method #isEnabled for the class TextCollectorView. How is the correct way to do that? I do not see a state value or an enable flag or something like that.
Or is there an another procedure?

If there's no way to disable a TextCollectorView, why not implement the method to always return true?
Anyway, i think it's a pretty neat additon to have a text cursor that is shown, when the mouse is over a text view :-)

Kind Regards
Karsten

The textcollector view could be wrapped in a wrapper that manipulates visibility and enablement, so perhaps make the method that tiny bit smarter:

isEnabled
    |wrapper|
    wrapper := self findParent: [:each | each isKindOf: WidgetWrapper].
    ^wrapper ifNil: [true] ifNotNil: [wrapper isEnabled].


I imagine this could be implemented much higher in the class hierarchy above TextCollectorView
