    I have a main window and it can call out a Dialog child window. And I want my main window to always stay on top of the dialog window, but only at the program's level. Adding a flag setWindowFlag(Qt::WindowStaysOnTopHint) in the constructor of the main window wouldn't do it because it makes it stay on top of everything in my desktop.

      So how do you expect to see your dialog then?

        I will resize my main window smaller. My dialog will update from changes I make in main window, so I need it to be always on top.

          Strange ui-design... don't set the mainwindow as parent of your dialogs so the main window can overlap them.

            They can be overlapped right now when I click on anyone of them, I just want the main window to always stay on top.

              The active windows is in forground - you can't really change this without asking the window manager (so it's wm dependent, nothing Qt can do for you here)
              Again: strange ui-design...

                What if I remove the main window from being the parent of the dialog window and then flag the main windows as Qt::Tool. Will it work?

                  So if your mainwindow is maximized or at the position the dialog is at and you open the dialog, you don't want to see it??

                    I won't be maximizing my main window, it would be relatively small compare to the dialog.
