      Well, if you minimize a window it is automatically hidden (that's why you minimize it in the first place).

      If you are talking about hiding the taskbar entry see "this":http://qt-project.org/forums/viewthread/8902 thread.

              So, what have you tried? How does the code look like? What did you expect? And what is it actually doing?

                QWidget widget;
                QMainWindow mainWindow(&widget);
                
                mainWindow.show();
                
                return application.exec();

                  Snippet #1 does not show a taskbar icon, and so does setting the Qt::Tool window flag - at least for me.
                  @
                  void MainWindow::changeEvent(QEvent *event)
                  {
                  if (event->type() == QEvent::WindowStateChange)
                  {
                  if (isMinimized() == true)
                  setWindowFlags(windowFlags() | Qt::Tool);
                  else
                  setWindowFlags(windowFlags() & ~Qt::Tool);
                  }

                  return QMainWindow::changeEvent(event);
                  

                  }@

                  Using ~WS_EX_APPWINDOW does, as mentioned in the linked thread, not work properly.

                        bq.

                         void MainWindow::changeEvent(QEvent *event)
                        {
                            if (event->type() == QEvent::WindowStateChange)
                            {
                                if (isMinimized() == true)
                                    setWindowFlags(windowFlags() | Qt::Tool);
                                else
                                    setWindowFlags(windowFlags() & ~Qt::Tool);
                            }
                         
                            return QMainWindow::changeEvent(event);
                        }
                        

                        I used that it works for hiding but when i want to show the form again

                        void myclass::trayicon_click(QSystemTrayIcon::ActivationReason reason)
                        {
                            if(reason==QSystemTrayIcon::Trigger)
                            {
                                show();
                            }
                        }
                        

                        it looks like this when i show the form !http://dl.2rialy.ir/ZiDoM-Ups/91/after.JPG(show)!

                            Use showNormal() instead.
