Member Data Documentation

vgui_adaptor * vgui_adaptor::current = 0 [static, inherited]

This static datum points to the adaptor that last received a mouse event.

It is set to zero if its pointer receives a LEAVE event. It will often point to the adaptor which was current when a popup menu was triggered, which is often what one wants it for.
