Hi @Vadimkuzmin,
You can only move the whole tab group (ControlWindow) to a different position.
you can test by adding ie.
void mousePressed() {
if (mouseButton == RIGHT)
cp5.getTab("default").getWindow().setPositionOfTabs(mouseX,mouseY);
}
the above moves the (invisible) ControlWindow upper/left for the Tabs to mouseX/mouseY on pressing right mouse button.
Cheers
