JInternalFrame, Swing, disable move functionality - how ?

[kelahcim]

Hi,

I have a problem with JInternalFrame, recently.
I would like to create such a JInternalFrame, that wouldn't be able to move.

At the end there is a small program which demonstrates what am I thinking
about.

You can see that there are three "panels"

1. JDesktopPane
2. JPanel
3. JTabbedPane

You can also see, that only panel able to stop JInternalFrame from moving is
JTabbedPane.

Can anybody tell me if this is a some kind of a parameter (which determines
whether Frame is able to move or not) or maybe I have to work harder to
obtain such an efect?

Best regards,

Michal

you need to install your own UI for this:

}

public BasicMyInternalFrameUI(JInternalFrame b) {
super(b);
}

protected MouseInputAdapter createBorderListener(JInternalFrame w) {
return new MyBorderListener();
}

protected class MyBorderListener extends BorderListener {

public MyBorderListener() {
}

public void mouseDragged(MouseEvent e) {
if (e.getSource() == getNorthPane()) {
return;
}
super.mouseDragged(e);
}
}
}

Thank you.

note, that in real life you should provide more UIs - not only Basic - at
least Metal, Windows and Motif.

Or...

So that you don't fall into the trap of having to support all
LookAndFeels on different versions on different platforms...

You could instead use a simple layout manager that would allow
positioning unless you 'freeze' one of it's children.

LayoutManager can't prevent you from dragging JInternalFrame

Sure it can.

One way is to use it's addLayoutComponet methods to hook in a
ComponentListener on any targeted JInternalFrames.


Or... one could hook the proper events from inside of subclass of
JInternalFrame itself, instead of using a custom UI.

it looks ugli.

it looks also ugli.

this is SUN mistake, they could have one boolean variable more.

the only one better way is to use GlassPane to filter out mouseDragged
events.

But wouldn't it block the dragging entirely in the component ?

no, because you can first check which component is currently under the mouse
and than decide to filter out or not.

But i have found a totally different solution for my problem.

If I am not wrong it is enought to call setMaximum(true).
Then I get maximized frame which fullfils totaly the DesktopPane and is
unable to move.

Well, it is not exactly what I ment to do, but in fact it does a thing.

I can dock and undock the frame from the JDesktopPanel.

sorry, but in your example middle frame got not all possible place.
I thought you need many not moveable frames in one container,

Yes, I know.

But I didn't know, that I can maximize jframe by hand, that's why I haven't
done it.
And I suppose I didn't expressed myself enough clearly :)

Sorry.
