Capture mouse extend event on a panel(CVI 6.0) but not on a control"

[chen]

The function EnableExtendedMouseEvents() can be called repeatedly to change the interval of a control's extended mouse events.But this function can't be used on a panel.
There is a function EnableExtendedPanelMouseEvents() in my attach files.This function can be called repeatedly to change the interval of a panel's extended mouse events. But it causes a large CPU usage.Can anyone explain to me how to do?

chen,

Are you trying to capture extended mouse events that occur anywhere in the panel? If so, you can then you can use a transparent canvas that is sized as large as the whole canvas to detect the extended mouse events (like EVENT_MOUSE_MOVE). I've attached an example of this code for you. Is this what you're trying to accomplish?
