Problem:
If special characters represented by 'AltGr' + 'z' or 'AltGr' + 'y' are inserted into a textfield, the undo or redo action
is perfomred instead of simply insert this special character.
Solution:
To properly intercept Ctrl-Z/Ctrl-Y keystrokes, it is not sufficient to only test for the 'Ctrl'-key being pressed.
Additionally, it must be checked that the 'Alt' key is not pressed. Otherwise, if heading for a special character
represented by 'Alt-Gr' + 'Z', that would result in an unwanted undo event.
That is because on Windows systems, the key 'Alt Gr' is composed of both of the keys, 'Ctrl' and 'Alt', respectively.
Plug-Ins changed:
- org.eclipse.scout.rt.ui.swing [UndoableEditObserver.class]
Migration:
None
