问题 How would you get a display of dockwidgets/centralwidget in which the dockwidget in the Qt::BottomDockWidgetArea or Qt::TopDockWidgetArea doesn't take Qt::LeftDockWidgetArea nor Qt::RighDockWidgetArea space? This is the actual display, with 2 dockwidgets and the central widget at the top right: This would be the preferred display: 回答1: you probably should use the QMainWindow's corner functionality to get the behavior you wanted.

问题 I have C++ widget code that was generated by QtDesigner (Qt open source v 4.7.3, using the Form->View Code menu in QtDesigner).

问题 I'm trying to figure out a way of using Qt Designer to make a dynamic GUI. For example, let's say I have a main window with a horizontal layout.
