[wxpython-users] Background image for Main Window

[Michael Moriarity]

Hi Tony:

I normally put a panel on the frame, then in the panel's __init__() I read
the background image into a wx.Bitmap:

self.BgBitmap = wx.Bitmap(BgFilePath)

and bind a handler for the Erase Background event:

self.Bind(wx.EVT_ERASE_BACKGROUND, self._OnEraseBackground)

In the handler, just blit the bitmap onto the panel.

    def _OnEraseBackground(self, Event):
        # Get an Erase DC.
        EraseDC = Event.GetDC()

        # If it is null, use a Client DC instead.
        if EraseDC is None:
            EraseDC = wx.ClientDC(self)

        # Blit the Background Bitmap over the Window.
        MemoryDC = wx.MemoryDC()
        MemoryDC.SelectObject(self.BgBitmap)
        EraseDC.Blit(0, 0, self.BgBitmap.GetWidth(),
self.BgBitmap.GetHeight(), MemoryDC, 0, 0)

        # Select out the Background Bitmap.
        MemoryDC.SelectObject(wx.NullBitmap)
