Re: Multiple documents

["Chris Garrett" <garrett91 hotmail com>]

Hi,

That is pretty much the way I thought I would have to do it.  However, I am 
experiencing some confusion about how to ensure that callbacks from the 
canvas end up resulting in changes on the correct image.  I havent written 
any code for multiple documents yet, since I am still thinking about the 
design of the structures etc.

I also need to consider a way for multiple views of the same document to be 
updated whenever changes are made...  I think the structs will have a lot of 
links in them so it is easy to pull out the ones needed in any given 
circumstance!

Is there any chance you could point me in the direction of your code so I 
can see how the callbacks are working?  This is the area I am having 
difficulty with (probably because I am still new to GTK).  I am making a 
pixel-based drawing program myself, but I dont intend it to compete with the 
GIMP - it would have more of a focus on image creation rather than image 
manipulation.

As far as the type of MDI I aim to use, it will be pretty-much like the GIMP 
in style - ie. no tabs and no WiW.  Ideology aside, I find WiW 
claustrophopic and I am not 100% sure that tabs are suitable for images.

Best regards,

Chris.
