keybindings and mouse events with a browser widget [message #991210]

I created a custom editor widget containing a browser widget. The problem is that I can't figure out how to get mouse or keydown events to the workbench. I want to be able to bind the save-funktion of the editor to a keydown event.

I tried to use the org.eclipse.ui.binding extension point
problem: it does not work if I have the focus on the browser widget.

I tried BrowserFunctions
problem: to save the content I have to call another BrowserFunction to fetch the content of the editor. It seems that it's not possible to call a BrowserFunction in another BrowserFunction.

I thought of firing an event via qooxdoo to force the workbench to save the open file via the command org.eclipse.ui.file.save, but I'm not sure how to do it. I can't access the the rap functions, because the browser widget is encapsulated by an iframe.

Another Problem which may be related to the iframe is the fact that the workbench doesn't receive clicks on the iframe(browser widget). For example if I create a menu via a BrowserFunction the menu does not close until I click an the menu or outside the iframe.

I would be very happy if someone could show me a solution.

I'm not exactly sure how your custom widget works, but calling a
BrowserFunction within a BrowserFunction shouldn't be necessary. Either
send all the data you need within the first BrowserFunction (they take
multiple arguments), or (much less optimal) use Browser#evaluate to get it.

Thx, I created a Browserfunction with an argument for the content of the editor and it works, but I have to specify the keybinding twice(editor + workbench).

I could not solve the menu problem though. If I create a Menu it does not close when I click on the browserwidget. Any ideas on this problem?

Assuming you mean a SWT popup Menu, this is a problem that can currently
not be worked around. However, we are aware that Browser and custom
widgets may cause such issues and plan to fix this in the near future.

As an workaround I created a BrowserFunction to set the focus as well as closing the menu if the Browser is already focused.

editorNode.addEventListener('mousedown', function(e) {
  if( e.button != 2 ){
    setFocusFunction();
  }
}, false);
