[osg-users] osgWidget::Label size adjustment

Hi, Im using osg 3.0.1 and i have problems with adjusting the size of a osgWidget::Label to its text. As far as i understand, without using setSize, the widget size depends on the length of the text and font type. I like this and i dont want to set the size manually, but the gap to the widget

[osg-users] clamp mouse cursor / position

Hi, I'm trying to keep the mouse cursor in a specific area, while dragging a widget. (f.e. scrollbar, 2d stick). I cannot use requestWarpPointer, because this will recursively call my mouseDrag event. Maybe its not a good behaviour at all, but still i wonder if its possible. ... Thank you!
