The center area can be occupied by any kind of QWidget.ĭialog Windows are used as secondary windows that present the user with options and choices. QMainWindow has its own layout to which you can add a menu bar, tool bars, dockable widgets and a status bar. The Application Main Window provides the framework for building the application's main user interface, and are created by subclassing QMainWindow. The QMainWindow class sets the Qt::Window flag in its constructor, as it is designed to be used as a window and provides facilities that are not wanted for child widgets. Depending on the window management system such secondary windows are usually stacked on top of their respective parent window, and not have a task bar entry of their own. In addition, a QWidget that has a parent can become a window by setting the Qt::Window flag. This is usually only wanted for one window in the application, the primary window. Primary and Secondary WindowsĪny QWidget that has no parent will become a window, and will on most platforms be listed in the desktop's task bar. For instance, selected windows of an application are represented in the task bar. Windows are typically integrated into the desktop environment and to some degree managed by the window management system that the desktop environment provides. Windows separate applications visually from each other and usually provide a window decoration that allows the user to resize and position the applications according to his preferences. In applications, windows provide the screen space upon which the user interface is built.

In Qt, QMainWindow and the various subclasses of QDialog are the most common window types. (Usually, windows have a frame and a title bar, although it is also possible to create windows without such decoration using suitable window flags). A widget that is not embedded in a parent widget is called a window.
