focus setting

Hi,
in Pharo 1.2 i could tab through the submorphs using tab and shift-tab.
in Pharo 1.3 shift-tab seems not to work anymore. what can i use to move
backwards through the morphs to set the focus?

Re: focus setting

bug in your copy of the image.. possibly..

shift-tab seems to work fine for me over most variants I have worked.. just hacked to also include tab windows through ctrl+tab.. which is actually missing.. capability.. when you want to cycle through windows within pharo

Morph>>tabKey: event

"Check for tab key activity and change focus as appropriate."

event controlKeyPressed

ifFalse: [event keyCharacter = Character tab

ifTrue: [event commandKeyPressed

ifTrue: [World tabOpenWindows: event].

event shiftPressed

ifTrue: [self navigateFocusBackward]

ifFalse: [self navigateFocusForward].

^ true]].

^ false

PasteUpMorph>>

keyStroke: anEvent

...

anEvent keyCharacter == Character tab

ifTrue: [self tabAmongFields

ifTrue: [

anEvent commandKeyPressed

ifTrue: [^ self tabOpenWindows: anEvent].

...

tabOpenWindows: aKeyboardEvent

| currentFocus index |

currentFocus := aKeyboardEvent hand keyboardFocus.

SystemWindow noteTopWindowIn: self.

SystemWindow topWindow sendToBack. " could actually raise the next window to top rather"

i just downloaded another Pharo 1.3, used one of the examples in the
unchanged image and got the same result.
i then made a descendant of StandardWindow with
handlesKeyboard: evt
^true
and:
keyStroke: anEvent
anEvent wasHandled: true.
self inform: anEvent asString .
while this reacts eg on tab or shift-up, it does not react on shift-tab,
somehow strange. and it shoudnt be the OS, since Pharo 1.2 gets the
shift-tab.

Re: focus setting

i noticed that although i dont get a keystroke event for shift-tab, i do
get keyUp and keyDown events. obviously they all come from the vm and
the new vm in Pharo 1.3 probably cant keep up with my very old linux
version. otoh i cant open the 1.3 image with the vm from Pharo 1.2 (This
interpreter (vers. 6502) cannot read image file (vers. 6505) ). i guess,
one day or another i have to update to a newer linux version. for the
moment i just changed the shift-tab keyDown event to a keystroke event,
since i need the keystroke event but not the keyDown one. or is there an
older vm more similar to the one in Pharo 1.2, that can open the 1.3 image?
