some Key Bindings not working [message #1297099]

Hello Graphiti Community,

I noticed that the default key bindings of my RCP app that uses Graphiti behave a bit strange because some of them work and some don't.

If I press [Del] the selected shape gets deleted, the DeleteFeature is invoked
If I press [Ctrl + C] nothing happens, the CopyFeature is NOT invoked
If I press [Ctrl + S] the diagram is saved
If I press [Ctrl + Z] nothing happens, the last modification is NOT undone

As far as I know, all of the above key bindings are defined by Eclipse and not by Graphiti.
In addition, I can invoke the actions that are not invokable by their respective key bindings by clicking the icons in the toolbar. Reviewing the code that generates the toolbar entries shows, that they are linked to the very same command IDs as the default key bindings.

Can you tell me how to make the key bindings work?
How can I make graphiti react to already defined key bindings?

Best regards,
Martin

Martin,

do you have an own subclass of DiagramEditor as your editor? In case yes,
you should also register an action bar contributor for that editor (see
org.eclipse.editor extension point), DiagramEditorActionBarContributor is
the default implementation that comes with Graphiti.

Dear Michael,

Thank you for your answer.

Yes, I use my own subclass of DiagramEditor and I also registered a custom action bar contributor which inherits from DiagramEditorActionBarContributor. It disables the contributions to the main menu by overriding contributeToMenu(IMenuManager) with an empty method. The remaining methods are inherited, especially buildActions(). As far as I understand, this method registers a number of retargetable actions such as copy, paste, delete, redo, undo etc. By doing this, I think the editor is supposed to automatically react to the respective shortcuts for the registered action, e.g. [Del] for delete.

But as I wrote in my previous post, not all of the shortcuts work as I expect them to do. [Ctrl + C] does not copy a Shape, but when the direct editing of a text is active, I am able to copy and paste text. So the editor is reacting to [Ctrl + C] somehow, but not when a Shape is selected.

So my question remains: How can I make [Ctrl + C] and [Ctrl + V] work for copying Shapes?

Best regards,
Martin

Hi Martin,

having the registrations of the actions in the action bar contributor is the
precondition. Besides that you should check that
DiagramBehavior.getCommonKeyHandler is called. It registers the keybindings
for copy, paste.

The direct editing replaces the global handlers when it becomes active, so
CTRL-C/CTRL-V behave differently. After deactivation the old handlers get
registered again.
