resize mdiArea with Mainwindow

SGaist

In that case, why don't you put the mdiArea directly as central widget with designer ?

freevrs

I have the auto created QWidget , auto named central widget.
For this i have selected vertical layout.

Below the QWidget i have the mdiArea.

How can i change this ?
Or is that correct ?

SGaist

Add mdiArea to the vertical layout and you should be good to go.

freevrs

I think that is what i done, but it still desn't work

SGaist

So what you want is to put all layout margins at 0 so your mdiArea widget will take the whole place

freevrs

I have done that, but the mdi area still does not scale out

SGaist

The question is going to be silly but did you just put it over the QMainWindow or did you explicitly clicked the layout vertically menu entry ?

freevrs

i clicked the vertical layout manualy on the central widget.
Also i cant put the mdi area over it.

SGaist

What do you mean by you can't put the mdi area over it ?

freevrs

I thougt i could mabey drag'n drop it

Here are all stepps i have done

Create Project with Widget
Created a mdiArea with designer
try to resize with code

SGaist

QWidget or QMainWindow ? In any case, you only need to put the QMdiArea in a layout on the widget

freevrs

Its a QT Widged Application

So i think it auto creates a MainWindow ??

I set the layout to vertical (see pictures in last postes)

SGaist

MainWindow can be a QMainWindow or a QWidget depending on what parameter you choose
