Hi
I have some QPopupMenu 's on the MenuBar.They are creating QDialogs (not modal one)for different purposes by executing similar code like below:

SignalProcessDialog *SPdialog=new SignalProcessDialog;
SPdialog-> show();

When the user activates another dialog (?SettingsDialog) the SPdialog goes to background(obscured by the mainwindow) and the user activate-create another one from the MenuBar if he needs to change a SProcess parameter.How can I get rid of these unused QDialog windows.How can I be aware of its existence and not to create again and raise it.
