Hi,
What flags do I need to set or which events do I need to catch to use the
TAB key as a traversal impulse in the context of a Text widget?
I have a series of Text widgets in a window one below the other. When
SHIFT+TAB is pressed, the focus jumps from a Text widget to the one above
it. I would like a traversal in the opposite direction to take place when
the TAB tree is pressed alone (i.e. the standard traversal behaviour). I
can't stop the Text widget from interpreting the TAB key as a tab stop,
though. I've tried catching the key with a listener and then setting doit to
false which does keep a tab from being inserted but it does not lead to a
traversal event.
Any help greatly appreciated,
Martin Maerker
