Maya mouse movement event, mouse dragging direction ?

[Virbhadra Gupta]

hey,

i creating code where we can update value by dragging mouse on maya view port.

i want to get mouse movement (up, down, right or left) or mouse cursor  anchor point.

i can query anchor point with draggerContext commant but it's gives only first point only.

so i am unable to know mouse dragging direction.

please let me know if my approach is right or wrong and how can we get mouse dragging direction.

You can use the dragger context to record mouse movement as long as he mouse click is held down, im pretty sure the docs have an example of exactly this under the dragger context command. If you want to record mouse movement without holding the button down then I think you’ll have to turn to QT...

Here is sample code. It will give first click value and keeps on giving same again so i am unable to know drag direction.

contx = "valueDrag"

def onDrag ():
x = cmds.dragferContext(contx, q=True, ap=True)
print x

if cmds.draggerContext(contx, q=True, ex=True):
cmd.deleteUI(contx)
cmd.draggerContext(contx, dc=onDrag, cur="tumble")
cmds.setToolTo(contx)
____________
Result will be like on mouse drag
All anchor point will come same it give only first point of click.

This is going to query the anchorPoint each time, which is the start point of the drag. You probably ly want to query the dragPoint to get the current position 

x = cmds.draggerContext(contx, q=True, dp=True)

    print x


if cmds.draggerContext(contx, q=True, ex=True):
    cmd.deleteUI(contx)
cmd.draggerContext(contx, dc=onDrag, cur="tumble")
cmds.setToolTo(contx)
