PySide and Maya2014

I've been working with PySide to make some tools for our Animation department. Part of that process involves a UI that is generated on the fly based on data read in from a spreadsheet.

It was important that each UI component had a unique and predictable object name so that I could access the information it contained and save it out later. In case anyone else needs to do it, or has a better way, here is an example of the process I use. 

Thanks to Nathan Horne and Chris Zurbrigg for their very useful examples!

# System

# GUI Modules
from PySide import QtCore, QtGui
import maya.OpenMayaUI as apiUI

# Allows converting pointers to Python objects
from shiboken import wrapInstance

def maya_main_window():
    main_win_ptr = apiUI.MQtUtil.mainWindow()
    return wrapInstance(long(main_win_ptr), QtGui.QWidget)

# Create out Dialog class, inheriting from QDialog
class Dialog(QtGui.QDialog):

    # Call the maya_main_window command to parent it
    def __init__(self, parent = maya_main_window()):

        super(Dialog, self).__init__(parent)

        # Create a list of rows and buttons
        self.rows = ["Row1", "Row2", "Row3"]
        self.buttons = ["Button1", "Button2", "Button3"]

        # And now set up the UI

    def setup_ui(self):

        self.main_layout = QtGui.QVBoxLayout()

        # Create a series of rows, and in each row, put our buttons
        for row in self.rows:

            self.row_Hbox = QtGui.QGroupBox()
            self.layout = QtGui.QGridLayout()

            for button in self.buttons:

                # Label the button with it's list name
                self.push_button = QtGui.QPushButton(button, self)

                # Give each button a unique object name
                self.b_name = row + "_" + button

                # Add a QLine Edit to each particular button
                self.q_line_name = self.b_name + "_TextEdit"
                self.my_line_edit = QtGui.QLineEdit()
                self.my_line_edit.setText("Hi! I'm " + self.q_line_name)
                # Also give it a unique name

                # Offset each button in the layout by it's index number
                self.layout.addWidget(self.push_button, 0, self.buttons.index(button))

                # Offset each QLine Edit in the layout to be underneath each button
                self.layout.addWidget(self.my_line_edit, 1, self.buttons.index(button))                

                # Connect the button to an event

            # Add the buttons to our layout

        # Set the layout and title
        self.setWindowTitle("Example Window")

    def on_button_event(self):

        sender = self.sender()
        print sender.objectName() + ' was pressed'

        # Get the text from the text line edit linked with the button
        self.line_edit_name = sender.objectName() + "_TextEdit"
        self.line_edit = self.findChild(QtGui.QLineEdit, self.line_edit_name)
        print self.line_edit
        print self.line_edit.text()

# Call our dialog   
dialog = Dialog()
