QSplitter + multiple layouts? how?

[jalla2000]

I simply want to split the window in two and use different layouts on either sides.

I have a main window and then i split it in half with a QSplitter. How can i add widgets to the left side of the splitter with a QGridLayout and add widgets to the right side using another layout? I can't add the widgets to the QGridLayout and then add the QGridLayout to the splitter since the layout is not a widget and the splitter does not have a addWidget function... Any help would be much appreciated...

EDIT: the splitter does have an addWidget function. but still... it doesn't solve my problem..
