Hi,

I have defined ExitAction and added to the view's menubar and
toolbar and context menu...
But the accelerator key is not display and also not working..

public ExitAction()
{
this.setText("E&xit\tCtrl+X");
this.setToolTipText("Exit the main window");
this.setAccelerator(SWT.CTRL+'X');
}

Why the Accelerator key is not working

Thanks in advance,
Swetha

Try with: E&xit@Ctrl+X

Hi,

If you want your action to be accessed by a shortcut you must associate
it to a command.

Use this extension point : org.eclipse.ui.commands
--> create a command
--> create a key binding associated to this command
commandId="your.command.id"
keyConfigurationId="org.eclipse.ui.defaultAcceleratorConfiguration "
keySequence="Ctrl+X"

In your code, register your action to this command
/* e.g. in the createPartControl */
YourAction action = ...;
IHandlerService handlerService = (IHandlerService)
window.getService(IHandlerService.class);
handlerService.activateHandler("your.command.id",new ActionHandler(action));

You don' have to set the accelerator in your action constructor, and the
key sequence is automatically added to the action label.
public ExitAction()
{
setId("my.exit.action");
setActionDefinitionId("your.command.id");
this.setText("E&xit");
this.setToolTipText("Exit the main window");
}
valere.

PS: take a look at this

Hi,

The following is included in plug-n.xml,I have just removed < > form
the actual code

extension
point="org.eclipse.ui.commands">
category
description="Actions take at lunch time."
id="view.keybindings.category"
name="endUser">
/category>
command
categoryId="view.keybindings.category"
description="Exit from the view"
id="view.keybindings.exit"
name="Exit">
/command
/extension

extension
point="org.eclipse.ui.bindings"
key
commandId="view.keybindings.exit"
contextId="keybindings.contexts.exit"
schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
sequence="CTRL+X"
/key>
/extension>

And in the View class I have included,

window = getSite().getWorkbenchWindow();
IHandlerService handlerService = (IHandlerService)
window.getService(IHandlerService.class);
handlerService.activateHandler("view.keybindings.exit", new
ActionHandler(exitAction));

And in the ExitAction class,

public ExitAction()
{
this.setText("E&xit");
this.setToolTipText("Exit the main window");
this.setId("EXIT");
this.setActionDefinitionId("view.keybindings.exit");

}

Still the shortcut key is not displaying as a label and its not working,
Am I doing anything wrong here,

Thanks in advance,
Swetha

Try this:

<extension
point="org.eclipse.ui.commands">
<category
description="Actions take at lunch time."
id="view.keybindings.category"
name="endUser">
</category>
<command
categoryId="view.keybindings.category"
description="Exit from the view"
id="view.keybindings.exit"
name="Exit"/>
<keyBinding
commandId="view.keybindings.exit"
keyConfigurationId="org.eclipse.ui.defaultAcceleratorConfiguration "
keySequence="Ctrl+X"/>
</extension>

You can enable tracing for the command framework :

In your launching configuration ( Run --> run...) go to the tracing tab
and check the following debug options :
org.eclipse.ui/debug=true
org.eclipse.ui/trace/keyBindings=true
org.eclipse.ui/trace/keyBindings.verbose=true
org.eclipse.ui/trace/sources=true
org.eclipse.ui/trace/handlers=true
org.eclipse.ui/trace/handlers.verbose=true
org.eclipse.ui/trace/handlers.verbose.commandId=org.eclipse. jdt.ui.navigate.open.type
org.eclipse.ui/trace/contexts=true
org.eclipse.ui/trace/contexts.verbose=true

Did you enable the tracing?
Look at the console output.

Hi,

The above code is working only for the first time the view is
opened....

If I open it again form the ShowView menu, the key binding is not working..

Thanks,
Swetha

Is the 'activateHanlder' call is in the createPartControl() method ?

handlerService.activateHandler("view.keybindings.exit", new
ActionHandler(exitAction));

Don't fill in the contextId ... unless you've created a special context
and are activating it and deactivating it. Leave it out and the binding
will be in org.eclipse.ui.contexts.window (which might not work for
CTRL+X), or create your own special context and active it in your
createPartControl(*)

You can just use getSite().getService(IHandlerService.class); ... then
your handler will be bound while your view is active. This is even more
important if you activate your own context for the keybinding.

It's fine to do this call in the createPartControl(*)

Hi,

I am confused.. I want to tell u once again what I am doing ..

In pulg-in.xml,

<extension
point="org.eclipse.ui.commands">
<category
description="Actions take at lunch time."
id="view.keybindings.category"
name="EndUser">
</category>
<command
categoryId="view.keybindings.category"
defaultHandler="org.eclipse.ui.handlers.IHandlerActivation"
description="Exit from the view"
id="view.keybindings.exit"
name="Exit">
</command>
<keyBinding
commandId="view.keybindings.exit"

keyConfigurationId="org.eclipse.ui.defaultAcceleratorConfiguration "
keySequence="Ctrl+3"/>
</extension>

And in the View Class,

in createPartControl() method,

IHandlerService handlerService = (IHandlerService)
window.getService(IHandlerService.class);
handlerService.activateHandler("view.keybindings.exit", new
ActionHandler(exitAction));
getSite().getService(IHandlerService.class);

And in the ExitAction Class,

public ExitAction()
{
this.setText("E&xit@Ctrl+3");
this.setToolTipText("Exit the main window");
this.setId("EXIT");
this.setActionDefinitionId("view.keybindings.exit");

}

This is working only for the first time the view is displayed.. If I close
it and open it again from the ShowView menu, its not working,... sorry for
irritating u all... Please tell me what I am doing wrong here

Thanks,
Swetha
