I don't know what you're doing, but it's pretty simple. I've enclosed a
sample app that displays a set of jpgs in an "Image directory".

There have been enough questions about this, I just may put this in the
Wiki.

Thanks Chris

That was very helpful. I agree that it may be helpful in the Wiki.

OK, there's a new page in the Wiki:

http://wiki.wxpython.org/index.cgi/wxStaticBitmap

--Enjoy, Chris

Hi all,

I just put a new page on the Wiki demostating changing the bitmap on a wxBitmap. I set it up with a wx.Sizer, so that the fraem woudl re-size itself to fit the StaticBitmap. However, I found I had to do:

         self.Image.SetSize( self.Image.GetBestSize() )

to reset the size before calling:

         self.Layout() self.Image.SetBitmap(wx.BitmapFromImage(Img))

to make the frame re-do the layout.

shouldn't the sizer use the BestSize anyway? is it a bug that I had to re-set it's size by hand?

The full demo app is at:

http://wiki.wxpython.org/index.cgi/wxStaticBitmap

Here is how the wx.StaticBitmap is put in the sizer:

         box = wx.BoxSizer(wx.VERTICAL)
         box.Add(b, 0, wx.CENTER | wx.ALL,10)
         box.Add(self.Image, 0, wx.CENTER | wx.ALL, 10)

( b is a wx.Button )

There is a flag for it. Use wx.ADJUST_MINSIZE when adding it to the sizer and then all you'll need to do is call Layout.
