Parameters
- y
- Y-coordinate
Return Value
Integer index of viewport row
This method (along with GetColumnViewportIndexFromX) allows you to retrieve the index of the viewport row or viewport column from pixel offsets. This is useful in mouse-handling to see in which viewport a mouse event (MouseDown, MouseMove, etc.) occurred.
The viewport row index is zero-based, so the first (top) viewport row has an index of 0.
