[GRASS-dev] switch active window on Map Display

[Wenzeslaus]

Hi Madi and list,

parent of window created from Layer Manager (your case) is Layer
Manager (the class GMFrame from wxgui.py). It contains references to
all Map Display Windows. You can get Map Display related to current
notebook page by:
self.parent.curr_page.maptree.mapdisplay

So you probably want to write this:
self.parent.curr_page.maptree.mapdisplay.Raise()

(I suppose that in __init__ you have: self.parent = parent)



I have general note to this. Maybe it is common problem that someone
want to get current Map Display. So some simple getter function should
be introduced:

class GMFrame(wx.Frame):
    # ...
    def GetCurrentMapDisplay():
       """!Returns current Map Display window"""
       return self.parent.curr_page.maptree.mapdisplay
