Hi,
When we are in text widgets and use shortcut keys the bound Eclipse commands
run instead of expected text behavior. In text widgets we would like
copy/cut/paste/delete to work in a text like manner. If we are not in a
text widget we would like the commands run.
Currently if we select a model object in a Tree, position into a text field,
select some text, and use M1+C, we copy the model object instead of the
text. The outcome is worse if we do the same except use the delete key as
we delete the model object. We noticed that if no model objects are seleted
we get expected text behavior while in text fields.
We are using Eclipse 3.3 menus/commands/handlers. We have defined our own
context for key bindings.
We found the org.eclipse.ui.textEditorScope context and tried to use it in
our activeWhen clauses....make the handler active when we are not in a text
widget. We discovered that o.e.u.contexts.dialogAndWindow/window were
active even while in a text widget and o.e.u.textEditorScope was not.
I'm hoping there is good way for us to get text behavior while in text
widgets and command behavior while elsewhere. Below I show some snippets of
our handlers/contexts/keys using copy as an example...they are similar for
cut/paste/delete.
Thanks,
Jim
Handler:
<handler
class="HandlerClass"
commandId="org.eclipse.ui.edit.copy">
<activeWhen>
<iterate
ifEmpty="false">
<adapt
type="modelType">
</adapt>
</iterate>
</activeWhen>
</handler>
Context:
<extension point="org.eclipse.ui.contexts">
<context
id="myContext"
name="myContext"
parentId="org.eclipse.ui.contexts.window">
</context>
bindings:
<extension point="org.eclipse.ui.contexts">
<context
id="myContext"
name="myContext"
parentId="org.eclipse.ui.contexts.window">
</context>
