selecting attributes in channelBox?

[martin tomoya]

Does anyone know a way to select attributes in the channelBox from a
python script?

[Nicolas Combecave]

I'd be very interested to hear about this too. We had to find a workaround, which involved selectionLists and dragAttrContext to manipulate channelBoxAttrs, but it was way more complicated than selecting directly the attribute via select -r persp.translateX for example, and being able to use the virtual slider...

is this to allow for the usage of the middle mouse virtual slider function?

when in a move mode, by clicking on one of the directional handles of any manipulator allows you to middle mouse drag after that in only that axis, or all three when you are in the transform mode
if you are trying to do it for attrs other than the default transforms then that is another story.

You're trying to perform the selection?
Not read the selection?
right?

yes I'm trying to select attributes in a channelBox, so I can use the
mmb slider function.
Not only for transforms but for all attributes (the original maya
channelBox behaviour)

Anyone has an idea how to do it?

I could suggest looking at HUD sliders instead, Maya's channelBox doesn't have the functionality to select attributes only query selected attributes

HUDsliders don't do MMB but does give you fast access from the viewport

thanks damon, but I need to be able to 'reproduce' the mmb
functionality based on attributes selected in another tool.
That's why I thought the most reliable way would be to be able to auto-
select attributes in the channelBox.

Internally the chanelBox just uses a dragAttrContext for MMB...you say
that there was something complicated about using one directly
yourself?

[Nicolas Combecave]

Definitely, you should look into building a selectionList, and trigger a dragAttrContext.
It's basically the way we do it here.

Thanks Tim.

How is the channelBox enableLabelSelection flag used?

  -enableLabelSelection (-els)        boolean       queryedit
    Enables the selection of attributes in the channelBox when used in conjunction with -attributeEditorMode. Default is false. Queried, returns a boolean.

How's it going Ted!

Off the top of my head I don't remember anything about that flag, and
just heading out for the long weekend, but if nobody gets back I'll
look at it Tuesday.

Funny, I was just in the middle of getting this to work myself. So far I think you need to use channelBox (q = True, sma = True) to query the selected main (top) channels. However, I haven't gotten it to work yet but perhaps if we all put our heads together, a solution will surface. :)

This will get the selected channels in the main channel box and append them to the list chList:

# ----- Start script ------

import maya.cmds as cmds
import maya.mel as mel

def getChannels (*args):

gChannelBoxName = mel.eval('$temp=$gChannelBoxName')
chList = cmds.channelBox (gChannelBoxName, q=True, sma = True)
if chList:
for channel in chList:
print channel
else:
print 'No channels selected!'
return False

getChannels()
