[Qt-interest] resize problem with nested layouts

[Eckhard Jokisch]

HI,
Iwant to place different widgets into the tabs of a tab view.
The widgets are created using designer as external *ui files.
In the external widget i.e. a QTableWidget is inserted in a gridlayout.
This widget allone resizes the QTableWidget according to the window size as 
exoected.
In the mainwindow I have a QTabWidget have a QGridLayout as child of a tab.
To the gridlayout of the tab I add the external widget (that contains a layout 
and a QTableView).
Now when changing the size of the mainwindow the tabWidget gets adjusted to 
the mainwindow size. But the tableWidget remeins constant.

How can I solve this?

Regards
Eckhard
