[platform-ui-dev] Fw: [platform-swt-dev] Key listener and Global actions

[Randy Hudson <hudsonr@xxxxxxxxxx>]

I have several questions.  First
of all, why is there still experimental API at this point?  Supposedly,
M6 was the deadline for all breaking changes.  So I don't see how
API which is available in M7 could be backed out. 

Second, related to the original post,
I have a Tool which would like to receive ALT+RIGHT whenever the user is
using "keyboard accessibility" to drag objects as an alternative
to using the mouse.  ALT is a modifier which means "don't snap
to grid, etc".  CTRL is also a modifier meaning "clone",
SHIFT = "constrained" operation.  So, I need the ability
to temporarily receive these keystrokes regardless of keybindings.

Another issue with GEF and keybindings
is our Palette.  We would like tools to be reached with a single key,
such as "C" activates the connection tool.  If we use a
keybinding, then the letter C cannot be typed anywhere in the editor, *even*
if we make the associated action disabled.  If we don't use a keybinding,
the user cannot modify the actual binding for the tool, so we have to re-invent
the keybinding preference page.

I'm pretty sure Nick said that if the
action bound to a keybinding is disabled (or bound to NULL), then the keybinding
service would stop consuming that key.  But this is not the behavior
we are seeing.  For example, we also need to receive CTRL+SPACE, which
has universal meaning of "toggle selection" of item with focus.
But the keybinding for Content Assist is getting in the way. Why do native
Trees and Tables receive CTRL+SPACE, but our Canvas does not?

Thanks,
Randy

Or if you just want to hook a handler for the existing
Back/Forward 
actions (menu items Navigate > Back and Navigate > Forward, which
are 
bound to Alt+Left Arrow and Alt+Right Arrow by default), use:
myEditorOrView.getSite().getActionBars().
setGlobalActionHandler(ActionFactory.BACK.getId(), handlingAction);

These kinds of questions should be asked on the newsgroup.

workbench.getCommandSupport().setKeyFilterEnabled(false);

Though IWorkbenchCommandSupport is still experimental API (i.e., we 
haven't 
decided that this will be the final API for 3.0).  If you have comments
about 
this API (e.g., missing functionality, etc.), please open a bug report
against Platform UI.
