QMdiArea with designer

**maximAL** · 6th September 2007, 18:06

hi,
i'm new to QT4 (user QT3 a while ago) and i'm trying to figure out how to use the QMdiArea widget in combination with the designer.
is there some clean way of inserting MDI areas? so far i only see the possibility of creating a plain SDI window and then restructure it in code to an MDI one.

You cannot do that. There is no logic in having the possibility to add MDI areas in Designer.
You couldn't add more than one anyway.

If you have to create a MDI interface, then do everything without designer(except maybe some components that don't depend on it).

You can place a QFrame on the form, right click it and promote the frame to QMdiArea. Just don't insert any widgets into that frame later (it'll still be a frame in Designer, but will be compiled as QMdiArea).
