Could anyone please provide an example or useful link or just briefly
explain how to define my own context for key bindings?
For example I want to define any text field or tree as a context to be
able to add any key bindings to it.
Regards,
Henry

Well, I am no expert, but here is what I did (following the advice of Paul Webster, whose webpage is
now part of the help docco):
a) plug into the "contexts" ext-point, with this:
<context
description="Key-binding context for Your Special Stuff"
id="com.mun.ist.special.context"
name="Special Stuff"
parentId="org.eclipse.ui.contexts.window"/>
b) plug into "commands" something like this (or choose some other menu category):
<command
categoryId="org.eclipse.ui.category.file"
description="Do your special thing, go out and download some code, e.g."
id="com.mun.ist.special.doit"
name="Do That Funky Thing"/>
c) plug into "bindings" like this (or choose some other scheme):
<key
commandId="com.mun.ist.special.doit"
contextId="com.mun.ist.special.context"
schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
sequence="M1+K"/>
d) and then for each action you plug in, use the corresponding "command-id" (as in # b) as the
"definitionId" of that action.
e) If you are in an RCP, you may need to activate the context you have defined, like this: in your
WorkbenchWindowAdvisor, method preWindowOpen(), call:
final IWorkbench workbench = PlatformUI.getWorkbench();
final IContextService cs =
(IContextService) workbench.getAdapter(IContextService.class);
cs.activateContext("com.mun.ist.special.context");
I'm not sure where to do that if you are writing for Eclipse itself (plugging in to the JDT, e.g.).
HTH,
Paul
