python - How do you query an object inside of a text field, to do something with it?

Question

I would like to know how to query a selection entered into a text field group, so I can do something with it. I have created a window to just translate an object that I loaded in the text field. The error is that cont is not defined.

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

def set_selected_name (text_field):
    cont = cmds.ls (selection = True)
    text_field = cmds.textFieldButtonGrp (text_field, edit = True,
                               text = ''.join (cont),
                               buttonLabel = '<<<<',
                               backgroundColor = [0.5098039215686274,
                                                  0.5098039215686274,
                                                  0.5098039215686274])
    return text_field

def translate_x(cont):
    cmds.setAttr( cont[0] + '.translateX', 10) 
       
def translate_y():
    cmds.setAttr( cont[0] + '.translateY', 10) 
       
def translate_z(*Args):        
    cmds.setAttr( cont[0] + '.translateZ', 10)




if cmds.window ('window1', q = 1, ex = 1):
    cmds.deleteUI ('window1')

cmds.window ('window1',
             title = 'Translate Attr',
             sizeable = 0,
             resizeToFitChildren = True,
             menuBar = 1)

cmds.rowLayout (numberOfColumns = 3)


cmds.separator (style = 'double',
                height = 6)

cmds.rowLayout (parent = 'window1',
                numberOfColumns = 4)

                               text = 'Obj',

                               buttonLabel = '<<<<')

cmds.showWindow ('window1')

Create any object you like, loaded into the text field and then try to translate with buttons.

Answer 1

You have several problems in your code.

1. In the translate commands you always use cont[0]. cont is only used in the function set_selected_name() and is a local variable what means it is deleted as soon as the function is completed.
2. You can use a string as command in the button command, but this only works with static values. You should use lambdas to use functions with arguments.

The cont Problem can be solved by using a global variable, but it shouldn't since global variables are the source of all evil. A much more elegant way would be to enclose you UI in one python class and use instance variables to get the selection.
