Is there any way to get the location of the cursor in the node graph?
There's a few reasons this would be useful, but.. currently I'm trying
to write a tool where you select a bunch of nodes, press a button and
have those nodes be moved to the mouse location - theoretically making
it easier to move nodes around while zoomed
I tried creating a node with nuke.createNode(), and querying it's
location.. but this isn't reliable: if I click first then it works, but
subsequent runs create the temp node just below the previous location,
no where near the mouse
def thing():
selection = nuke.selectedNodes()
[n.setSelected(False) for n in selection]
# Get mouse position
n = nuke.createNode("NoOp")
x, y = (n.xpos(), n.ypos())
nuke.delete(n)
# Restore selection
[n.setSelected(True) for n in selection]
# Do something interesting with mouse position
b = nuke.nodes.Blur()
b.setXYpos(x, y)
nuke.menu("Nodes").addCommand("thing", thing, "alt+a")
Only other way I can think of is with PySide: you could get the mouse
coordinates, and using the DAG widget get "widget space" coordinates..
but I can't think of a way to transform these into nodegraph coordinates
(maybe impossible without changes to Nuke, at which point it would be
just as easy to add a "getMouseCoordinates" method)
