I just downloaded Xojo and am exploring a few things. The docs for the MouseUp event state…
However, it appears the mouse cursor does not have to be released within the control’s bounds in order to trigger the event. Instead, it seems that as long as the MouseDown occurred within the control’s bounds, the MouseUp will fire, and the X/Y arguments indicate the position of the mouse relative to the control’s top left corner at the time the mouse is released (even if it’s released outside the control’s bounds).
I’m just wondering if my observation is correct or if I’m missing something.
