Stuck converting a PyQt UI to Pyside in Maya 2014

I’m taking a simple PyQt UI from Maya 2013 and converting to Pyside for maya 2014 and I’ve hit a snag. My UI does not use a .ui file, it is a very simple tool.

I’ve followed along with some of the findings by Nathan Horne and Jason Parks, but I am hitting snag I haven’t seen covered since most of their examples assume you have a .ui file to load.

Here is the error I get:


# Error: TypeError: file ********.py line 40: 'PySide.QtGui.QWidget' called with wrong argument types:
  PySide.QtGui.QWidget(PySide.QtCore.QObject)
Supported signatures:
  PySide.QtGui.QWidget(PySide.QtGui.QWidget = None, PySide.QtCore.Qt.WindowFlags = 0) #

Here is what my class looks like:


class MyUIClass(QtGui.QWidget):
    def __init__(self, parent=getMayaMainWindow()): 
        super(MyUIClass, self).__init__(parent) # <--- This is where the error is occuring.

Not sure what Pyside is expecting… thanks!

I found the source of the problem. The problem arose from using code snippets from two sources that weren’t compatible with each other.

I needed to modify Nathan’s getMayaMainWindow to use the Pyside wrapinstance function

Original:


def getMayaWindow():
	"""
	Get the main Maya window as a QtGui.QMainWindow instance
	@return: QtGui.QMainWindow instance of the top level Maya windows
	"""
	ptr = apiUI.MQtUtil.mainWindow()
	if ptr is not None:
		return sip.wrapinstance(long(ptr), QtCore.QObject)

Modified in bold:


def getMayaWindow():
	"""
	Get the main Maya window as a QtGui.QMainWindow instance
	@return: QtGui.QMainWindow instance of the top level Maya windows
	"""
	ptr = apiUI.MQtUtil.mainWindow()
	if ptr is not None:
		[B]return wrapinstance(long(ptr))[/B]

Was having the exact same issue today, but I get a typeError when I try this:

# TypeError: wrapInstance expected 2 arguments, got 1 #

What worked for me is this:

return wrapInstance(long(accessMainWindow), QtGui.QWidget)
