Hi,
I have a rather simple goal, but I cannot figure out how to do this:
I want key bindings only be active when the menu is visible. The menu includes a special toolchain, which shall be reachable only when a certain editor type is open.
For that I have defined a menu contribution, which only gets visible, when the active editor is of a certain kind, done through core expression - works fine. That menu is attached to a command id, for which in turn I defined a key binding.
Now, when the menu is invisible (no such editor active), then the key binding is still active, which is bad. Defining a context for it should do it somehow, but the only thing I got to work was defining a context "org.example.my.ui.KeybindingScope" and by letting the Editor set the scope when opened:
protected void initializeKeyBindingScopes() {
setKeyBindingScopes(new String[] { "org.example.my.ui.KeybindingScope" });
System.out.println("Activating my key binding context ...");
}
Unfortunately the key binding is now only considered active when the editor is focussed, whereas the menu visibility is true as long as the editor is "opened" (which is the wanted behavior).
How do I set the key binding to be effective ONLY when the menu is visible, or better - only for that certain kind of editor?
plugin.xml:
<extension
point="org.eclipse.ui.commands">
<category

name="Esterel Category">
</category>
