Coding the Mousewheel

[FoxEgg]

I cannot find many tek-tips on mousewheel use...

And the 'help' file isn't particularly

PROCEDURE Object.MouseWheel
LPARAMETERS nDirection, nShift, nXCoord, nYCoord

I have a Grid and highlighted a row.. but the wheel part of the mouse seems to do nothing...

Can I code it?

What do you want to do? The event fires when you scroll the mouse wheel. You can put code to respond to that in the event method.

Thanks Tamar

Well when the grid has focus and has a row highlighted... and I scroll down... then can get it to skips a row

ie
SKIP +1

Likewise up

SKIP -1

...

The value of nDirection in the .MouseWheel() event is 120 for a forward movement and -120 for a backward movement.

As Tamar suggests, you could put suitable code in the .MouseWheel() event itself - or pass the value of nDirection or alternatively, .T. or .F., to an object method containing suitable code.
