maya Creating PyQt GUI With Maya Creating PyQt Window

Example

This is a very basic example how to load a pyqt ui file to maya with pyqt libs. In this solution you really don't need to convert your pyqt ui file a python file. You can simply load your pyqt ui.

from PyQt4 import QtCore, QtGui, uic
import maya.OpenMayaUI as mui
import sip

baseUI                    = "/user/foo/bar/basic.ui"
baseUIClass, baseUIWidget = uic.loadUiType(baseUI)

class Ui_MainWindow(baseUIWidget, baseUIClass):
    def __init__(self,parent=None):
        super(baseUIWidget, self).__init__(parent)
        self.setupUi(self)


def getMayaWindow():
    ptr = mui.MQtUtil.mainWindow()
    return sip.wrapinstance(long(ptr), QtCore.QObject)

def mayaMain():
    global maya_basicTest_window
    try:
        maya_basicTest_window.close()
    except:
        pass
    maya_basicTest_window = Ui_MainWindow(getMayaWindow())
    maya_basicTest_window.show()

mayaMain()
