Questions tagged [qmdiarea]

The QMdiArea widget, part of the Qt framework, provides an area in which MDI windows are displayed.

QMdiArea functions, essentially, like a window manager for MDI windows. For instance, it draws the windows it manages on itself and arranges them in a cascading or tile pattern. QMdiArea is commonly used as the center widget in a QMainWindow to create MDI applications, but can also be placed in any layout.
