Custom Qtoolbox : some problems

[dr23]

Hi everybody,
I post for the fisrt time here. I would to customize a Qtoolbox but i did not succeed. I would like to enlarge (height) each widget of the Qtoolbox. but i don"t know how to do this. with the Qdesigner, we can't. I take a look at the official QT documention 4.1 and try some function of Qwidget. but nothing happened.
Moreover I try to modidy SPACING property (SPACING appears in QTdesigner; default value is 6. when we change it, it's not taken into account in QT designer code). No information in QT documentation to do it manually.

thank for your help
and have a good day
