Detecting closed output windows?

[Antonio]

Hi all,

I'm using an Output Window for some stuff, and I'd like to free
resources when the window is closed.

Any ideas on how to do this?

Thanks,
Antonio

Hmm - similar as I had with windows closed in the Navigation area. I assume you have already thought about having something listening to changes of the Output Window. So if you know how to get to the output window and if the output window has a addChangeListener you could do in the listening class something like

OutoutWindow.findInstance().addChangeListener(WeakListeners.change( this, OutputWindow.findInstance()));

Unfortunately do I not out of my head the "OutoutWindow" name ... and alos if it has a addChangeListener.

After this just act on it in your void stateChanged(ChangeEvent e) method of the listening class ...


B-)

Hi,

The fact is that I've copied the source code of the Output Window system
and I've build a TopComponent that contains a single "Tab" of the
"OutputWindow". I can now add that TopComponent to any mode I want.

That's the best solution I could find. I know I'll have to maintain it
myself, but well, I can keeps things under control (I've changed the
font to "Courier New", for instance ).

This is under beta now, I may push it to contrib if people is interested
in this.

Cheers,
Antonio

Antonio,

I see where you did your own thing, but you can also do this using the TopComponent.Registry of the WindowManager. See:
http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/WindowManager.html#getRegistry()
http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/TopComponent.Registry.html#addPropertyChangeListener(java.beans.PropertyChangeListener)
where you can listen for
http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/TopComponent.Registry.html#PROP_TC_CLOSED

also see:
http://java.sun.com/j2se/1.5.0/docs/api/java/beans/PropertyChangeEvent.html#getNewValue()

to get the closed component. Should be a TC I believe...maybe not though.
