i got the solution
self.setCentralWidget(getMelWindow())
where getMelWindow() routine query the mel Layout
def getMelWindow():
ptrLayout = mui.MQtUtil.findLayout(“myWin|clmn”)
return sip.wrapinstance(long(ptrLayout), QtGui.QWidget)
i m still working on it, if you guys are having different ideas or already done this before, please let me know
