Gxt focus management

Question

I am working with Gxt. I need to set focus to the first enabled field on the page. But I have a lot of pages and I want to centralize that behaviour. There is a lack of documentation in Gxt so I wonder if somebody has met such a problem and can help me.

Now it goes like that in each component's class

protected void resetFocus() {
    combobox.focus();
}

@Override
public void show() {
    super.show();
    resetFocus();
}

I have found com.extjs.gxt.ui.client.aria.FocusManager but is absolutely unclear how can I use it. Or maybe It is also possible to get chain of fields as they go on the component according to the focus. And I can move resetFocus method to the parent class.

Smth like that

protected void resetFocus() {
    *getFocusChain().get(0).focus();*
}

Maybe you can show us your code? It doesn't make people want to help with your problem when you call it a trivial task, it makes you seem lazy in the research part of the problem. — Woot4Moo, Nov 03 '10 at 14:27
Thanks, you are right! I realized that my post shows me not from a best side. I will rewrite it. — Zalivaka, Nov 03 '10 at 18:18

Based on the last response, I got this to work in a GXT3 window by doing the following:

@Override
public void show() {
    super.show();
    Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand() {
        @Override
        public void execute() {
            field.focus();
        }
    });
}

This way when the window opens, the field has focus and you can begin typing.

Focus after render some delay So you have to use Scheduler.get().scheduleDeferred method. Or DeferredCommand on GWT 1.7 or before.

Example of usage:

Scheduler.get().scheduleDeferred(new ScheduledCommand() {

    @Override
    public void execute() {
        widget.focus();
        widget.el().focus();
        widget.getElement().focus();
    }
});

It isn't helpful at all. I was looking for solution I can implement once and do not copy-paste focus() code. I have made my own focus management system, so the question is no more actual. – Zalivaka Apr 13 '11 at 14:23
Why don't you share your solution here. Maybe your solution will help other people. – Yusuf K. Apr 19 '11 at 12:08

At least it worked for me. I was using scheduleFinally which doesn't work, scheduleDeferred did the trick. I used only someTextField.focus(), in GXT 3 it seems to be enough. – PhiLho Feb 29 '12 at 10:12
