Accessing editor actionbar contribution [message #447767]

Hello,

I have an action on the toolbar (contributed by my editor). Its a
radiobutton. Now I need to get a reference to this action object to
determine its state. How to do it?

Thanks

What I need - I have three checkbox buttons in the CoolBar and only
two of them can be activated in the same time. I do not know, how to
deactivate one since I do not have a reference to other actions from
the coolbar in the run(Action delegate) method.

I created them in the plugin.xml:

<action
class="cz.upol.jo.app.editors.actions.ConstrainZ"
id="cz.upol.jo.editoraction.constraintz"
label="Z"
state="false"
style="toggle"
toolbarPath="scene_constraint"/>
<action
class="cz.upol.jo.app.editors.actions.ConstrainY"
id="cz.upol.jo.editoraction.constrainty"
label="Y"
state="true"
style="toggle"
toolbarPath="scene_constraint"/>
<action
class="cz.upol.jo.app.editors.actions.ConstrainX"
id="cz.upol.jo.editoraction.constraintx"
label="X"
state="true"
style="toggle"
toolbarPath="scene_constraint"/>

I cannot find the method returning me the action (by an id).

From your IEditorSite you can get the IActionBars and the appropriate
manager. Then use IContributionManager#find(*) to find the
IContributionItem that you need.

You have to walk the hierarchy of the path you specified (toolbarPath,
menuPath, etc).

When you do this, you get a
org.eclipse.ui.internal.PluginActionContributionItem, which doesn't give
you access to any methods to query the state of the item if it
is a TOGGLE or RADIO button.

If you can get access to the ToolBar, you should be able to access the
ToolItem, which contains the information needed. But, I can't find a way
to do that.

If it's a PluginActionContributionItem it's also a
org.eclipse.jface.action.ActionContributionItem, which has getAction().
IAction has an isChecked() method.

But this is a hack. I'm still looking for the proper way to access the
state of a contributed action.

Thanks. This seems to work. I would be interested in knowing if there is
a better way of doing this.

The way that these things are moving is to Commands, Handlers, and Bindings.

It looks like you can use definitionId in your action declaration to
link it to a command. Define a command in the org.eclipse.ui.commands
extension point. Using a definitionId and a command turns the legacy
actionSet or editorAction actions into handlers.

Use ICommandServer#getCommand(String commandId) to get the Command.

From Command, you can use getState(IMenuStateIds.STYLE), and then if
your command state is an instance of ToggleState, use
((Boolean)state.getValue()).booleanValue().

I tried what you suggest. I created a command, and put its id as the
definitionId of the editorAction. Then, I tried to access it via,

CommandManager manager = new CommandManager();
Command command = manager.getCommand( "commandId" );

At this point, I'm not seeing any way to get at the state or other
information about the contribution. Am I missing something or doing
something wrong?

You need the command service.

Object serviceObject = PlatformUI.getWorkbench()
.getAdapter(ICommandService.class);
if (serviceObject != null) {
ICommandService service = (ICommandService) serviceObject;
..............
}

In 3.1.2 I think you would need the global command service, and in 3.1.2
you use getAdapter(*) to retrieve services.

In 3.2, the services should be retrieved from the IServiceLocator
"closest" to them. i.e. in an editor, you would use
getSite().getService(ICommandService.class).

I appreciate you trying to help me, but I'm just not seeing how this
helps. Once I have the ICommandService, I still don't understand how to
get at the information I need to find out the state of the button. I can
get the Command using the command's id, but I still see no way of getting
to the state of the button.

From Command, you can use Command#getState(IMenuStateIds.STYLE), and
then if your command state is an instance of ToggleState, use
((Boolean)state.getValue()).booleanValue().

Are we talking 3.1.2?

I don't see a getState method in the Command class.

ah, I'm on 3.2. It doesn't look like there are equivalent methods on 3.1.x.
