top level panel's decorations

wxPython Users

Hi All,
In order to ease the creation of application documentation I added a
screen-grab btn to my app's toolbar. The code snippet below implements
this functionality.

Is there a way (in Linux), to get the whole toplevel screen with all
it's decorations - status and toolbar, not only the client area?

def snapshot(self):
        """
        get a snapshot of the current screen and save to file
        """

        panel = wxGetTopLevelParent(self)
        context = wxClientDC(panel)
        
        memory = wxMemoryDC()
        x,y = panel.GetClientSizeTuple()
        bitmap = wxEmptyBitmap(x,y, -1)
        memory.SelectObject(bitmap)
        memory.Blit(0,0,x,y, context, 0,0)
        memory.SelectObject(wxNullBitmap)
        
        bitmap.SaveFile("test.png", wxBITMAP_TYPE_PNG)

regards

1) Use a wxWinbdowDC, rather than a wxClientDC to blit from

2) If you want the status bar and all, then you need the wxWindowDC of
the wxFrame

3) Beware that if there are other windows over yours, or a open menu or
something, that may be what you get.

4) I havn't actually tried this myself

5) You probably can't get all the window decorations at all: they are
drawn by the Window manager by in X, and wxWindows doesn't know anything
about them. However, you probably don't need that anyway.
