Insert UI elements into existing layouts

[lala_ghost]

For example I would like to add an button to the shelf and I query the shelf with this:
import maya.cmds as cmds

a = cmds.layout('Shelf', query = True, childArray = True)
b = cmds.layout(a, query = True, childArray = True)
c = cmds.layout(b, query = True, childArray = True)
d = cmds.layout(c[1], query = True, childArray = True)
e = cmds.layout(d[1], query = True, childArray = True)
print e

Its only an example! I would like to add a button by script between 'shelfButton1' and 'shelfButton2', the first object in 'e'.
This is a shorter and easier to understand version of my actual problem.
Hope you can help!

Answering in case you haven't made any headway on it.

First you need to create your shelf button using the cmds.shelfButton command. It's up to you to work out the styling on that, but ensure you use the parent flag to select the proper shelf. See below.

cmds.shelfButton(parent=d[1])

Then you can use the position flag to reposition shelf buttons within your shelf using cmds.shelfLayout. The position flag requires a string and an int. The string is the child by name that you would like to move (I've used string.format to achieve this), and secondly is the 1-based index of where you want to move the button to. Since the newly created shelf button is added as the last item of a shelf, I can easily select it with a -1 index.

cmds.shelfLayout(d[1], edit=True, position='{0}'.format(e[-1]), 2))

These are the 2 things you need to be on your way to figuring out how this all fits into your code. Hope this helps!

Thanks al_ka!

Works great, maybe you have another idea how to add a button at a specific position to the main status line(see screenshot)?

My code so far:
`import maya.cmds as cmds
MainStatusLineLayoutChildren = cmds.layout('MainStatusLineLayout', query = True, childArray = True)

a = cmds.layout(MainStatusLineLayoutChildren[0], query = True, childArray = True)

cmds.nodeIconButton('testIconButton', style = 'iconOnly', image1 = 'file.png', parent = a[0])`

I currently don't know any way around this (at least not with python). The shelf can do this because it has parameters for re-organizing it's layout since it's designed to be dynamic. The main status line controls however (and most other layouts) are static and things can't be added unless it's done to the end. If you're happy adding things to the end, I would use cmds.symbolButton for this rather than nodeIconButon.
