Qt 4.7 - size of widgets

Hello,

i've set up an angstrom linux and installed Qt 4.7. I can create windows
and populate them with several widgets.

The problem is, that widgets are to small ( e.g. QSlider ) to work properly
with the touchscreen. I tried to use the resize function of QSlider, but
the slider only gets longer. The slider element itself is still to small to
drag and drop it precisely on the touchscreen.

I only use C++ to build my application, nothing like Qt Designer or QML. I
noticed, that Qt Designer does not provide some Widgets that I need, e.g. a
QToolBar.

Did you try to set width and height for window?
