can anyone shed some light on this?
i am trying to use the new 'treeView' gui in python.
this gui comes with allot of great callback triggers and would have
allot of great functionality for what i am trying to use it for.
however, i am currently stumped:
i cannot assign python functions as callbacks.
i have tried every conventional way of doing this, ways that work find
on other interface callbacks,
(string formating for positional arguments, lambda, functions that
accept variable numbers of args..
below are examples of each). but i always get an error with a memory
address included. like:
// Error: <function at 0x000000001E39A208> "layer 1" "newname"; //
// Error: Line 1.1: Syntax error //
is it possible that even though they say this gui is availabe for
python, that it really is not??!, because this looks like it may be
expecting only a mel proc as a callback.... because of the syntax
error thing.
here are four python examples of ways of doing this that work fine on
other gui:
(i am creating the callbacks on the 'editLabelCommand' signal.
so try to double click on the treeViewItem and rename it after
creating each example to see my problem)
###### example1: positional arg failure treeView example
def foo(a, b):
print a, b
return a
from maya import cmds
window = cmds.window()
layout = cmds.formLayout()
control = cmds.treeView( parent = layout, numberOfButtons = 3, abr =
False, elc = foo)
cmds.formLayout(layout,e=True, attachForm=(control,'top', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'left', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'bottom', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'right', 2))
cmds.showWindow( window )
cmds.treeView( control, e=True, addItem = ("layer 1", ""))
###### example2 wild-card args function positional arg failure
treeView example
def poo(*args):
print "callback args: " + str(args[1:])
return args[1]
from maya import cmds
window = cmds.window()
layout = cmds.formLayout()
control = cmds.treeView( parent = layout, numberOfButtons = 3, abr =
False, elc = poo)
cmds.formLayout(layout,e=True, attachForm=(control,'top', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'left', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'bottom', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'right', 2))
cmds.showWindow( window )
cmds.treeView( control, e=True, addItem = ("layer 1", ""))
###### example3: "catch-all arg" lamba positional arg failure treeView
example
def goo(arg1,arg2):
print "callback args: " +arg1)
return arg1
from maya import cmds
window = cmds.window()
layout = cmds.formLayout()
elc_cmd = lambda *args: goo(arg1,arg2)
control = cmds.treeView( parent = layout, numberOfButtons = 3, abr =
False, elc = elc_cmd)
cmds.formLayout(layout,e=True, attachForm=(control,'top', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'left', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'bottom', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'right', 2))
cmds.showWindow( window )
cmds.treeView( control, e=True, addItem = ("layer 1", ""))
###### example4: string positional arg failure treeView example
def goo(arg1,arg2):
print "callback args: " + str(args[1:])
return arg1
from maya import cmds
window = cmds.window()
layout = cmds.formLayout()
elc_cmd = "goo(\'%(1)s\',\'%(2)s\')"
control = cmds.treeView( parent = layout, numberOfButtons = 3, abr =
False, elc = elc_cmd)
cmds.formLayout(layout,e=True, attachForm=(control,'top', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'left', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'bottom', 2))
cmds.formLayout(layout,e=True, attachForm=(control,'right', 2))
cmds.showWindow( window )
cmds.treeView( control, e=True, addItem = ("layer 1", ""))
