Not sure why you would want to use pymel operations on the UI elements when you already have the more robust PyQt interface to them. The QListWidgetItem's being returned have a text() method already, so you won't need to look them up twice:
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qlistwidgetitem.html#text for item in myListWidget.selectedItems(): print item.text() or, you can do it in a list comprehension: textValues = [item.text() for item in myListWidget.selectedItems()] There is more than one way to find an existing window... To find a window that already exists, by name, you can use OpenMayaUI.MQtUtil.findWindow() http://goo.gl/wV5CG from PyQt4 import QtGui win = QtGui.QDialog() win.setObjectName("fooWindow") import maya.OpenMayaUI as mui if mui.MQtUtil.findWindow("fooWindow"): print "Exists!" This approach will return an actual QWidget swig pointer. If you just want to know if it exists, by name, you can use the cmds.window() cmds.window("fooWindow", exists=True) On Thu, Oct 25, 2012 at 6:02 AM, Ali Khanbabaei <[email protected]>wrote: > it is true.it should delete window. > send a part of your code that i see > > On Thursday, October 25, 2012 3:27:27 PM UTC+3:30, Panupat > Chongstitwattana wrote: > >> Ah that looks pretty neat.
