Hi,
is there a way to prevent dialogs from being closed when the ESC key is
pressed?
I create the dialog with the styles TRIM_DIALOG and APPLICATION_MODAL
and have a table and tableEditor component in it.
Now I want the table editor to react in a certain way when the user
presses the ESC key to discard the changes, he is currently performing
on the table cell. As editor I show a Text component, which has a key
listener attached to it. I tried to catch the ESC key in this listener,
but when the ESC key is pressed, the dialog closes immediately, which is
not what I want.
Can anyone give me any hint?
TIA
Christian

Christian Riedel:
I am not sure, but if you use JFace Dialog, you can try use different
button id than CANCEL_ID.
Hm... May be this will not help...
Look in class Decorations (in Win32 version), method WM_HOTKEY(). It
checks for SWT.CLOSE style of Shell, so create dialog without this style
(setShellStyle() method) and close it yourself using method close().
