A good point, there's definitely other ways around the problem. The idea
was based on a tool someone here wrote for Houdini - it seemed useful,
and I wanted to see how well it'd work in Nuke.
Might have worked, or maybe not.. but regardless, being able to query
the cursor location has other interesting uses (one random example:
being able to do custom drawing on the nodegraph, I have the drawing
part working, but again encountered the same stumbling block of turning
screen coordinates into nodegraph space -

Not being a smart ass, but since the click on your DAG already dictates
where nodes can be created/pasted, why not go simple...

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)
