Warning: the following is based on MPL 0.90.1 (yeah, I know, but it works. We have a branch that works with 0.98 but it hasn't been merge back in. Your mileage may vary.) Our popup code does: (note that in the bit below, self is a subclassed object based on FigureCanvasWxAgg) mouseLocation = wx.GetMousePosition() pos = self.ScreenToClient(mouseLocation) height = self.figure.bbox.height() x = pos.x y = height - pos.y (pickType, pickDetails) = self._pick(x,y) # NB: This is a custom pick routine written before the new pick code .... self.popup = ProbePopupWindow(self, wx.SIMPLE_BORDER, series.getName(), mouseLocation) where ProbePopupWindow is a subclass of wx.PopupWindow, and the positioning bit in the __init__ is: self.Position(mouseLocation, (10,10)) HTH, Anthony. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
