[FNR] Memory leak when closing a window

[rzschech]

I have discovered a memory leak when closing a window. My profiler shows that the eventPreview is the cause.

Adding to the close method:


if (eventPreview != null) {
eventPreview.remove();
}

similar to what is in the hide method fixes the problem.

Fixed in SVN.

Thanks!

Also if I hide() a window then close() it, it does not get unregistered from the WindowManager as close immediately exits if the window is hidden and therefore leaks.

Showing a hidden window then closing it is a work around.

In general should hidden windows be eligible for garbage collection from the GXT point of view?

If you want to hide it, than you want to hide it and reuse it.

If you dont want the window anymore, than you have to close it.

OK, so closing a hidden window causes a leak too.

That is not the common way to go. We will look into it.
