Eclipse RCP Toolbar buttons with the Eclipse Look

问题

In Eclipse, its easy to specify buttons for your toolbar using the ActionSets extension point. However, when I need to specify some items programmatically, I can't get the same look. I don't believe that the framework is using native buttons for these, but so far, I can't find the right recipe to match the Eclipse look. I wanted to see if anyone has found the right snippet to duplicate this functionality in code.

It's difficult to tell from your question, but it sounds like you may be attempting to add a ControlContribution to the toolbar and returning a Button. This would make the button on the toolbar appear like a native button like you seem to be describing. This would look something like this:

IToolBarManager toolBarManager = actionBars.getToolBarManager();
toolBarManager.add(new ControlContribution("Toggle Chart") {
    @Override
    protected Control createControl(Composite parent)
    {
        Button button = new Button(parent, SWT.PUSH);
        button.addSelectionListener(new SelectionAdapter() {
        @Override
        public void widgetSelected(SelectionEvent e) {
                // Perform action
            }
        });
     }
});

Instead you should add an Action to the toolbar. This will create a button on the toolbar that matches the standard eclipse toolbar buttons. This would look something like this:

Action myAction = new Action("", imageDesc) {
    @Override
    public void run() {
        // Perform action
    }
};

IToolBarManager toolBarManager = actionBars.getToolBarManager();
toolBarManager.add(myAction);

Could you perhaps put in an extract of the code you have for adding actions programmatically to the toolbar? I assume you do this in an ApplicationActionBarAdvisor class? Their should be no difference in the look of buttons you add declaratively vs those you add programatically.
