int, with the GUIEventAdapter MouseButtonMask, which is a completely
different type.

mouseButtonPress. Take a look at the code comments in the EventQueue header
Hi, everybody
In the GUIEventAdapter.h, we can see
enum MouseButtonMask {
LEFT_MOUSE_BUTTON= 1<<0,
MIDDLE_MOUSE_BUTTON = 1<<1,
RIGHT_MOUSE_BUTTON = 1<<2
};
so right key's value is 4.
and we can easily get num = 4 from
int num = osgGA::G
5 matches
