    Thank you.
    I made the following changes:

        setWindowFlags (Qt::Popup);
        review_Window->setWindowTitle ("Review");
    

    The new window does stay on top. I have 3 dialogs open:
    mainwindow
    additem
    review_Window

    Review_window is generated by additem. When review_window opens (and stays on top) it closes additem which I still need open. How can I keep additem open?
    Thank you.

      Hi you must show the code for how you open
      additem and review_Window
      as there is no reason for review_window to close additem so I assume
      its something with your code. Like using exec instead of show or
      using a local variable for additem so it runs out of scope and be deleted.

        Here is the code opening additem:

            Additem mAddItem;
            mAddItem.setModal (true);
            mAddItem.exec ();
        

        and this opens review_Window:

            review_Window->isModal ();
        
            review_Window->show ();
        
            review_Window->setFocus ();
        

        Thank you for your help.

          Hi
          Additem mAddItem;
          is local variable it seems but you are using exec() should should not run out of scope.
          Please put a break point on next line after
          mAddItem.exec ();

          and see if it for some reason falls out of exec() when u open review_Window.

          Do you use a slot/button to call the code that opens review_Window?

            Hi,

                Additem mAddItem;
                mAddItem.setModal (true);
                mAddItem.exec ();
                break;
            
            

            generated an error message: break statement is not within a loop or switch.

            Yes, the review_Window is opened in a function triggered by a slot/button.

            Thank you.

              mdditem mAddItem;
              mAddItem.setModal (true);
              mAddItem.exec ();
              int a=100; <<< break point here.

                Hi
                I tried.

                    Additem mAddItem;
                    mAddItem.setModal (true);
                    mAddItem.exec ();
                    int a = 100;
                

                Nothing really happened except I got a message saying unused variable.

                  hi
                  did it stop at break point when review_window open?
                  meaning it went from
                  mAddItem.exec (); << should stay here
                  int a = 100; << should not go to this line when review_window

                  also
                  review_Window->show ();

                  this is how u open review_Window still ?

                  Else Im afraid I cant guess what you are doing wrong.
                  Normally its not an isses to have 2 dialogs so must be some small details.
                  So u are almost there:)

                    Hi
                    It did not stop at breakpoint.
                    I open review_Window like this:

                        review_Window->setFocus ();
                        review_Window->show ();
                    

                    New development:
                    I haven't changed anything. Now all 3 windows (mainwindow, additem, review_Window) stay open. They are stacked from top to bottom like this: additem, review_Window, mainwindow. The minimize button doesn't work when all 3 windows open. If I close one of them everything works. No idea why. Thank you for your help.

                      Hi
                      When you call exec on a dialog, it become modal.
                      This means that other windows are blocked. also including minimize button.
                      http://www.informit.com/articles/article.aspx?p=1405225&seqNum=5

                      That might be the reason.
