[SOLVED] detecting when a mdi window is closed

**elcuco** · 9th September 2006, 15:04

Hi,

My application has a QWorkspace, and I am adding to it a tab bar, to look like a QTabWidget. I am trying to detect when a window is closed, to update the window list. I am using this code:

Qt Code:

Switch view

connect( widget, SIGNAL(destroyed(QObject*)), this, SLOT(windowDeleted2(QObject*)));
 
...
void qmdiWorkspace::windowDeleted( QObject *o )
{
	int windowNumber = workspace->windowList().lastIndexOf(dynamic_cast<QWidget*>(o));
	if (windowNumber!=-1)
		tabBar->removeTab( windowNumber );
}

connect( widget, SIGNAL(destroyed(QObject*)), this, SLOT(windowDeleted2(QObject*)));

...
void qmdiWorkspace::windowDeleted( QObject *o )
{
	int windowNumber = workspace->windowList().lastIndexOf(dynamic_cast<QWidget*>(o));
	if (windowNumber!=-1)
		tabBar->removeTab( windowNumber );
}

To copy to clipboard, switch view to plain text mode

Now that function is never called. It seems that pressing the X on the windows, hides then and does not close them. Does anyone have an idea about a possible fix? another implementation of this feature?

I also read this thread, but I found no solution to my problem.
