I read a lot about problems with keybindings and yesterday I also got into
trouble.
1. Goal: A popup menu in a view which is also accessible by an accelerator.
2. plugin.xml Configuration (only the important parts):
<extension
point="org.eclipse.ui.popupMenus">
<viewerContribution
targetID="com.camline.so.rcp.genview.Dispatch"
id="com.camline.so.rcp.genview.Dispatch.actions">
<action
enablesFor="1"
label="%soReserve"
definitionId="com.camline.so.client.reserve"
class="com.camline.so.rcp.actions.ReserveAction"
tooltip="%soReserveTooltip"
menubarPath="entryActions"
id="com.camline.so.rcp.actions.ReserveAction"/>
</viewerContribution>
...
</extension>
<extension
point="org.eclipse.ui.commands">
<category
description="Command for a button bar"
name="com.camline.so.client.ButtonBar"
id="com.camline.so.client.buttonBar"/>
<command
category="com.camline.so.client.buttonBar"
description="Reserve"
categoryId="com.camline.so.client.buttonBar"
name="%soReserve"
id="com.camline.so.client.reserve"/>
<keyBinding
string="Ctrl+r"
scope="org.eclipse.ui.globalScope"
command="com.camline.so.client.reserve"
configuration="org.eclipse.ui.defaultAcceleratorConfiguration ">
</keyBinding>
</extension>
3. Result:
The popup menu appears correctly, the action is accessible by mouse and
the corresponding menu item shows "Reserve Ctrl+R" correctly.
Accessing the action using the Ctrl+R shortcut does not work. The trace
says
KEYS >>> WorkbenchKeyboard.press(potentialKeyStrokes = [CTRL+R])
KEYS >>> WorkbenchKeyboard.executeCommand(commandId =
'com.camline.so.client.reserve')
KEYS >>> not handled
4. Solution or workaround
I added the following lines in my ReserveAction class, which implements
IViewActionDelegate.
public void selectionChanged(IAction action, ISelection _selection) {
this.selection = (IStructuredSelection) _selection;
if (action.isEnabled())
view.getSite().getKeyBindingService().registerAction(action) ;
else
view.getSite().getKeyBindingService().unregisterAction(actio n);
}
}
Now everything works as expected.
5. Final question
I would have expected, that this works automatically. So the following
questions go to the Eclipse wizards out there:
- Is this the correct solution to the problem?
- Is this a workaround needed because I made something wrong in plugin.xml
configuration?
- Is this a workaround for an Eclipse bug or a missing feature?
Many thanks in advance.
Best Regards,
Matze
