This gets overwritten -^

What is self.panel, as opposed to self.frame.panel?

Hi Emiliano, it isn't clear what you are trying to do here, you seem to
have a panel being created in 3 different places -- which one do you
want? I suspect that the self.panel, is hiding the other panel
that you created (self.frame.panel) which is the drop target (just a
guess)

I've never used xrc, but this works for me (is it what you want?)

class App(wxApp):
    def OnInit(self):

        self.res=wxXmlResource("test.xrc")
        self.frame=self.res.LoadFrame(None,"FRAME1")
        self.frame.panel=XRCCTRL(self.frame,"panel")

        dt=FileDropTarget()
        self.frame.panel.SetDropTarget(dt)

        # The following lines break the drag and drop
        sizer=self.frame.panel.GetSizer()
        sizer.SetSizeHints(self.frame)

        self.frame.Show()
        self.SetTopWindow(self.frame)

        return True
