emit a signal into an MdiSubWindow

[Qtdigitex]

here's the function that load the document ( QWidget ) :

def load(self):
    ImageProject = OIWid()
    self.mdiArea.addSubWindow(ImageProject)

def load(self):
    ImageProject = OIWid()
    self.mdiArea.addSubWindow(ImageProject)

To copy to clipboard, switch view to plain text mode 

i skipped details , but that's it. it's the code that load my widget.

if i make ImageProject an instance variable of my main class ( QMainWindow ) : self.ImageProject instead of ImageProject,

the last opened Project would be self.ImageProject and not the current active window !
