[Gtk2hs-users] Image Viewer with pan and zoom?

[Mark W. <mwa...@bi...>]

Hi,

I am trying to create a panel to display an image that I can pan and 
zoom in and out. From what I can tell, the out of the box widgets 
supported by Gtk2Hs don't support anything like this. Am I right?

If this is the case, then I see three options:

1. Someone has developed at gtk widget (gtk-image-viewer) for image 
viewing with pan and zoom. If I could build this, is there an easy way 
that I can 'register' it with Gtk2Hs and use it?

2. I could use the standard image viewer widget (Image) and add the 
required mouse events BUT I can't see a way of displaying a *scaled* 
pixbuf. How can I do this?

3. Someone has already done this can could lend me the code :)

I am on windows.
