Linux issue: Cannot Bring QMainwindow to Front if QDialog is active

[nbkhwjm]

I have a situation where i show a dialog by menu action from mainwindow. the dialog shows fine, but will always be on top of mainwindow.

In windows xp, the mainwindow can move to the top, but in linux it does not.
I have tried many different constructors, and i can get a couple to work right in windows, but never linux.

my constructor look like this

extlogwindow = new ExtLogWindow( 0 ); 
extlogwindow = new ExtLogWindow();

extlogwindow = new ExtLogWindow( 0 ); 
extlogwindow = new ExtLogWindow();

To copy to clipboard, switch view to plain text mode 

Attached is a sample application

There is an additional issue that is somewhat related, since i want this dialog to be closed when the mainwindow is closed, i made the mainwindow the parent of the dialog. by this constructor:

extlogwindow = new ExtLogWindow( this );

extlogwindow = new ExtLogWindow( this );

To copy to clipboard, switch view to plain text mode 

If I use this constructor, the dialog is closed properly when the mainwindow is closed. If i use the above methods to solve the issue in windows, then the dialog remains open after i close mainwindow... so i think dialog needs to have mainwindow as its parent.

Thanks in advance.

We solved it by using the following constructor / option

extlogwindow = new ExtLogWindow( );
 
	extlogwindow->setWindowFlags(Qt::SubWindow);

extlogwindow = new ExtLogWindow( );

	extlogwindow->setWindowFlags(Qt::SubWindow);

To copy to clipboard, switch view to plain text mode
