Open and close a qwidget dialog in a utility Plugin

[rodbrew2]

What is the proper way to open and close a qwidget dialog window in a utility plugin?  I currently have the dialog open but when I close it it goes away but if I move off the Utilities tab and back again it will pop up again.  So somehow it is not closing correctly.  I haven't found a good modal window using qwidget in the sdk so I'm kind of winging it.

Thanks for any help.

Looking a little farther into this it's not so much closing the qwidget window as it is destroying the utility itself when the X on the qwidget window is pressed.  I'm not sure how to tie those two together.  I hope this makes sense.

Doesn't deleting your qwindow is enough ?

Supposing your window is named "MyWindow"

class MyWindow(QWindow):
    def __init__(self, ...):
        # your stuff here

    def closeEvent(self, *args):
        del self

Hey Bendo I'm thinking it's not the qwidget window that's the problem it's actually shutting down the Utility plugin itself that seems to be missing.  For instance if I add a button for the plugin on the Utility panel and press it the UI comes up and the button remains pressed.  If I close the UI the button remains pressed.  If I cycle it again the UI comes up as normal.  If I don't unpress and navigate away from the utility panel and then back the button is still blue and the UI pops up again.  I guess this is kind of expected as it does it with a normal rollout.  A good example of the behavior I'm looking for is the Polygon Counter utility but with the qwidget.

Ok I think I got something figured out.  Not sure if it's the best way but it seems to work.  I added a closeEvent to my main UI in which I call the closeUtility function for my instance of the Utility plugin.  I also have a flag that keeps track of whether the UI dialog is open of not.  Like I said I'm not sure if this is the ideal way but it seems to work.

void Utility::BeginEditParams(Interface* ip, IUtil* u)
{
	this->iu = u;
	this->ip = ip;

	if (dialogOpen == FALSE)
	{
		dialog = new UtilityUI_Main;

		dialog->setWindowModality(Qt::WindowModal);

		dialog->show();

		dialogOpen = TRUE;
  }
	u->CloseUtility();
}

void UtilityUI_Main::closeEvent(QCloseEvent* event)
{
	if (myUtility.iu)
		myUtility.iu->CloseUtility();
	dialogOpen = false;
}
