getAttr(channelBox=1) broken in Maya 2012?

Coding
1

Hello!

I’m tyring to query if an attribute in the channel box is locked but not hidden. (Locked and visible in channel box)

Here’s the code I’ve got:
if getAttr(‘object.attribute’,locked=1) and getAttr(‘object.attribute’,channelBox=1): # locked but visible
print('I’m locked but you can see me! ')

What I’m trying to see is if an attribute is locked but visible in the channel box :

even if I just do:
if getAttr(‘object.attribute’,channelBox=1) : #If attr is visible in channel box
print(‘whatever…’)

Maya doesn’t return anything.

So basically, How can I get maya to return if an attribute is locked but is visible in the channel box?

Hey Age,

I had a look at this. Needless to say my Maya scripting knowledge is limited atm. It does seem like it’s not working as intended, as it will return True if the attribute is not keyable, but False when it is and for everything else (lock,hide).

The documentation is quite vague about what the command actually does (doesn’t use the word visible but show instead) as well as it mentioning that keyable attributes are shown.

I tried to query it using the attributeQuery command as well and even though it recognises the attribute it doesn’t seem to recognise if it’s keyable or hidden either.

To answer your question - I’m not sure how else you’d query for the visibility of the channel. This link here seems to allude to the function working however I can’t seem to get it to work. :o(

Here is the code I was using anyway…


import maya.cmds as cmds

objAttr = "obj.testAttr"

def getAttrStatus():
    if cmds.getAttr(objAttr,lock=1)==1 and cmds.getAttr(objAttr,cb=1)==1: # locked but visible
        print("I'm locked but you can see me! ")
    else:
        print "Returned false"

Sorry I couldn’t help. :frowning:

Hi! and thanks for your help!
So I’ve learned that for some reason (probably a bug) Maya associates the keyable flag with the channelBox flag.
Long story short I found this backwards way of seeing if an attribute is locked but visible in channelBox, and here it is:

if getAttr(‘obj.attr’,l=1) and not getAttr(‘obj.attr’,k=1): # locked and hidden
state = 0
elif getAttr(‘obj.attr’,l=1) and getAttr(‘obj.attr’,k=1) : # locked and visible
state = 1
elif getAttr(‘obj.attr’,k=1) : # keyable
state = 2

Just a side note:
In your code:
if cmds.getAttr(objAttr,lock=1)==1 and cmds.getAttr(objAttr,cb=1)==1: # locked but visible

You dont have to say “==1”. Python assumes it equals 1 if you say “if”.

so this would work the same:
if cmds.getAttr(objAttr,lock=1) and cmds.getAttr(objAttr,cb=1): # locked but visible

or…

is_locked = cmds.getAttr(objAttr,lock=1)
cb_visible = cmds.getAttr(objAttr,cb=1)
if is_locked and cb_visible : # locked but visible
