KeyBindings in RAP [message #729579]

I have a lot of actions in my RAP application (menu actions, context menu actions. other actions) for which I need to add keyboard shortcuts. These have been added by defining keybindings in my manifest using 'org.eclipse.ui.binding', All of these were working in my RCP version of the application, but in RAP they don't.

So, I used the following code to add my key bindings :
display.setData(RWT.ACTIVE_KEYS,new String[]{"My key combination -Ex CTRL+F11"});
display.addFilter(SWT.KeyDown, new Listener() {

public void handleEvent(Event event) {
// Invoke action here
}
});

This works as expected.
I want to know is if there's an easier/non-programmatic way to do it. Because this way of doing it is quite tedious, given the number of actions I need to register.

Hi,
the 'org.eclipse.ui.binding' extension point should work in RAP too. If
not, please file a bugzilla with a simple project to reproduce it.
Thanks,
Ivan

I just used the said extension point for the first time in my RAP application and they (bindings) seem to work pretty well.

May I ask how you did it? Because for me only the default key bindings work. The custom ones that I define at the application level are not sent to the server at all. I also saw that the RWT_ACTIVE_KEYS is set to the default set of keys (which is basically the short cut keys available in Eclipse RCP).

I didn't use any direct code. Here's a snippet from my plugin.xml:

<extension
         point="org.eclipse.ui.bindings">
      <key
            commandId="Lchat.deleteGroup"
            contextId="org.eclipse.ui.contexts.window"
            schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
            sequence="DELETE">
      </key>
   </extension>

This binds the Del key to the command "Lchat.deleteGroup". That's all I did!

Note that I only use commands, not actions, after reading this:

According to the documentation, you need to set the RWT.DELETE_KEYS value to those custom keys you want sent to the server (so they are not processed by the browser).

My question is what values do you use for key strings? "My key combination -Ex CTRL+F11" seems a little arbitrary. I am assuming that strings corresponding to the SWT. key code member names expressed as strings are the ticket, but ASSUMING has gotten me in trouble in the past. Does anybody have a clarification?

I'm assuming you mean CANCEL_KEYS. Just making sure.

This is explained on the JavaDoc for the ACTIVE_KEYS/CANCEL_KEYS
constants. Apparently we should make that clear in the documentation.

Greetings,
Tim
