Is there a resizeable layout

[jacek]

You need a splitter (third or fourth item in the "Form" menu).

Oh, I overlooked it completely - maybe because those splitter layouts are allways disabled (greyed out). Are they not applicable on the top level (main window), or are there any other constraints?

Edit:

Stupid me, the two related widgets must be selected to enable the sptitter layouts of cause.

Thanks!
