feed user input value back to an attribute

[Jason Huang]

Hi everyone,

I am new to the forum. Please bear with me if my question sounds too vague.

Trying to create a simple spreadsheet-like interface to list the value of selected attribute and be able to update/feed the user input value back to the attribute shown in Attribute Editor.

Here is the mock up code.

import maya.cmds as cmds

cmds.window(title = "test window", w=400, h=600, mxb=False, mnb=False)
mainLayout = cmds.columnLayout(w=400, h=600)
cmds.tabLayout(imw=5, imh=5)
vrayMtlList = cmds.ls(type = "VRayMtl")
cmds.columnLayout("Material matte ID", w=400, h=600)

for vrayMtl in vrayMtlList:
    if cmds.objExists(vrayMtl + ".vrayMaterialId"):
               
        currentMatteID = cmds.getAttr(vrayMtl + ".vrayMaterialId")
       
        matteIdValue = cmds.intFieldGrp(numberOfFields = 1, label=vrayMtl + "_matteID", value1 = currentMatteID)
       
cmds.showWindow()

I was able to get a simple GUI with integer fields show up with current VRay material multimatte ID displayed.
I want the Attribute Editor multimatte be updated when users type in new multimatte ID and press the "Enter" or hit a "Button", but could not figure out how.
I have tried to define a function to be called in the intFieldGrp or see if I missed a flag that can achieve this easily.

Any input would be much appreciated.

Thanks!

Hi,
Use "changeCommand" flag to attach a function to intFieldGrp.

If you have some arguments to pass, you have to use partial from functools :



from functools import partial

def myFunction(myArg01, myArg02, *args):
    print myArg01, myArg02

arg01 = "first value"
arg02 = "anything"

cmds.intFieldGrp(numberOfFields = 1, label=vrayMtl + "_matteID", value1 = currentMatteID, changeCommand = partial(myFunction, arg01, arg02) )




I hope it help.

also check out connectControl, it will create a two way connection between your ui and ae

Thank you all guys! I was able to achieve the functionally I wanted with the functools. Will give the connectControl a try at some point.

Cheers,
