How can I disable Quick Access TextField in Eclipse RCP Application

问题

today I changed my Eclipse IDE from 3.7 to 4.2 and my plugin-project has a new feature in the Statusbar of the UI called QuickAccess. But I dont need it, so how can I disable this feature, because the position of my button bar has changed...

回答1:

Go to Help --> Install New Software https://raw.github.com/atlanto/eclipse-4.x-filler/master/pdt_tools.eclipse-4.x-filler.update/

Install that Plugin and Restart the Eclipse. Quick Access automatically hide. or else you have an option to hide Window --> Hide Quick Access.

For all who have the same problem, it seems that this new feature is hardcoded and can't be disabled :/ https://bugs.eclipse.org/bugs/show_bug.cgi?id=362420

Here's a post that shows a way to hide it with CSS. Verified with Eclipse 4.3

Lars Vogel just reported in his blog post "Porting Eclipse 3.x RCP application to Eclipse 4.4 – now without QuickAccess box":

Bug 411821 ([QuickAccess] Contribute SearchField through a fragment or other means) is now solved.
Thanks to René Brandstetter:

If a RCP app doesn't provide the QuickAccess element in its model, than it will not be visible. So the default is no QuickAcces, easy enough? :)

See the commit 839ee2 for more details

Provide the "QuickAccess" via a e4 application model fragment inside of the "org.eclipse.ui.ide.application".
This removes the "QuickAccess" search field from every none "org.eclipse.ui.ide.application".

You could also hide it and make it work comparable to how it used to work in Eclipse3.7: when user presses ctrl+3 Quick Access functionality pops up (In Eclipse4.3 the ctrl+3 shortcut is still available).

Example of code you could add to your implementation of WorkbenchWindowAdvisor (for Eclipse4.3 rcp application)

private IHandlerActivation quickAccessHandlerActivation;

@Override
public void postWindowOpen() {
    hideQuickAccess();
}

private void hideQuickAccess() {
    IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
    setQuickAccessVisible(window, false);

    final IHandlerService service = (IHandlerService) window.getService(IHandlerService.class);
    quickAccessHandlerActivation = service.activateHandler(QUICK_ACCESS_COMMAND_ID, new CustomQuickAccessHandler());
}

private void setQuickAccessVisible(IWorkbenchWindow window, boolean visible) {
    if (window instanceof WorkbenchWindow) {
        MTrimBar topTrim = ((WorkbenchWindow) window).getTopTrim();

        for (MTrimElement element : topTrim.getChildren()) {
            if (QUICK_ACCESS_ELEMENT_ID.equals(element.getElementId())) {
                element.setVisible(visible);
                if (visible) {
                    Composite control = (Composite) element.getWidget();
                    control.getChildren()[0].addFocusListener(new QuickAccessFocusListener());
                }
                break;
            }
        }
    }
}

private class QuickAccessFocusListener implements FocusListener {

    @Override
    public void focusGained(FocusEvent e) {
        //not interested
    }

    @Override
    public void focusLost(FocusEvent e) {
        ((Control) e.widget).removeFocusListener(this);
        hideQuickAccess();
    }

}

private class CustomQuickAccessHandler extends AbstractHandler {
    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {
        IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        final IHandlerService service = (IHandlerService) window.getService(IHandlerService.class);
        setQuickAccessVisible(window, true);
        if (quickAccessHandlerActivation != null) {
            service.deactivateHandler(quickAccessHandlerActivation);

            try {
                return service.executeCommand(QUICK_ACCESS_COMMAND_ID, null);
            } catch (NotDefinedException e) {

            } catch (NotEnabledException e) {

            } catch (NotHandledException e) {

            }
        }

        return null;
    }

}
