why cannot the Shift+Tab key be detected?

I would like to map outdent to Shift+Tab when there is a selection.

I can detect the Tab key, but Shift+Tab never makes it to the event handler.

In fact, even

    Sensor kbdTest

seems to be able to detect Shift+Tab.

Any ideas why?

Hi Chris,

putting this into TextEditor >> #dispatchKeyboardEvent: brings the expected effect:

(aKeyboardEvent shiftPressed and: [aKeyboardEvent keyCharacter = Character tab])
        ifTrue: [self halt].

So, everything works fine. Maybe it is because those text editors handle those events and the Morphic event handler does refuse to handle them? Where do you try to handle it? You have to use TextMorphForEditView, because the PluggableTextMorph(Plus) gets keyboard events only in rare occasions...

Best,
Marcel

The most likely place for a problem would be the platforms/unix/sqWindows.c (or maybe sqEvents.c ?) since the interpreter and cog trees are not currently in sync. If a change to make tab get handled was put into the interpreter tree it may very well have not made it to cog yet. It’s even possible that the combination simply doesn’t get handled by the OS keyboard handler; I’ve seen siilar problems before now.

I wondered that too, which is why I verified it working in GEdit...
