Hi !

I was wondering if it is possible to override Eclipse own "internal default" Key listener?

I have made a key listener that checks for CTRL+SHIFT+END
and it works ok, but Eclipse also reacts to it and does its thing
(marking text from cursor to end of page) in editor window.

This two actions (Eclipse and mine) 'collides'.

I have tried with keyevent.doit = false
but to no avail.

(Besides isn't that .doit for my listener and not Eclipse default listener?)

So, anyone with knowledge/experiences/ideas as to how to prevent Eclipse form reacting on "my" keybinding(s).

Hi,

you can define your own schema:

Hi Lars !

Making a schema doesn't seem to help.

I have made a plugin that has a modified editor and I tried both making my own keylistener (as previously mentioned)
and also tried to bind command with a handler and a binding (to no avail).
I now have made a new schema and tried the binding (Ctrl+Shift+End) there but still Eclipse does it's own thing
just after mine thereby erasing my wanted result. I am clueless atm :-/.

Is there a way to get some 'message' when Eclipse own internal listener has executed a command maybe?
If so maybe I could let that trigger my command. I don't want to poke in "Eclipse internal code"..

Thankful for any help !

Hi,

you can check the keybindings, see:
http://www.vogella.de/articles/EclipseCodeAccess/article.htm l#keybindings

Perhaps this helps.

Best regards, Lars

Hi Lars !

I got the expected output except the last line with the function.
Could I have missed some setting?

Output in Console:

KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x0, keyCode = 0x40000, time = 22719658, character = 0x0)
KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x40000, keyCode = 0x20000, time = 22719938, character = 0x0)
KEYS >>> Listener.handleEvent(type = KeyDown, stateMask = 0x60000, keyCode = 0x1000008, time = 22720157, character = 0x0)
KEYS >>> WorkbenchKeyboard.press(potentialKeyStrokes = [CTRL+SHIFT+END, CTRL+, CTRL+SHIFT+])

Also regarding the schema - I might have put the
plugin_customization.ini file at the wrong place, will get
back on this once I am sure I got it in the right place.

also, Thank You for Your time and expertise !

Hi !

Problem solved !

I overlooked a Key Released event Embarrassed

So all Lars suggestions worked, but was "overwritten"
by the key released event.
