scrolling mouse event with a graph

[bgr]

Hi,
How to associate scrolling mouse event with a graph in his calback ?
at present, I use a EVENT_LEFT_CLICK_UP event and a EVENT_RIGHT_CLICK_UP event to make it.
I want to use the scrolling event to define the scale factor (I.e. google earth).
Must i create a specific mouse hook ?
if yes, how ?
thanks for your helps.

Hello bgr,

If you're using CVI 8.1 or later, there is an event, EVENT_MOUSE_WHEEL_SCROLL, that is sent to the control callback whenever the user operates the mouse wheel.
