[cells-gtk-devel] Re: List still alive?

[Peter Hildebrandt]

Hi Carlo,

I'm glad you're joining the community!  I believe cells-gtk is a great  
project (in some important respects the best GUI toolkit I have used so  
far), and it'd be great to see it growing even better.

As far as my work is concerned, Peter is exactly right:

I have just finished moving back from Berkeley to Germany and gotten back  
to work on the drawing area widget based on cl-cairo2.  My plan for the  
next week or two is to catch up with Tamas' recent work on cl-cairo2 and  
put together a close-to-release version.

My current state of development runs quite stable (I'm using it heavily in  
my reserach project and I haven't found bugs in a while), but still lacks  
a few things
- there is no support for drawing (bitmap) images
- the redrawing mechanism is built around the very first prerelease of  
cl-cairo2
- postscript/pdf export

My current issue with the newer versions of cl-cairo2 is that they depend  
on XDamage -- and I want to avoid introducing a dependency in cells-gtk  
(especially, since GTK tells us when a redraw is necessary, hence we do  
not need XDamage anyway).  Tamas, if you're reading this, what would you  
suggest?

Additionally I have worked on the listbox widget and added the capability  
to edit entries right in the listbox.  Once the editing is completed, a  
lispy callback function is called to deal with the new value.  This one is  
ready to commit -- I'll mail out a patch soon.

Based on that I've built an editable property list for my app, somewhat  
like the "object inspector" in GUI builders such as Delphi.  You supply it  
with a list of entries (field-name, getter-fn, setter-fn, editable-p), and  
it shows a three-column listview (field-name, current-value, read-only  
(bool)).  (I haven't found a way yet to make only certain rows editable.   
It seems that in GTK a column as a whole is editable or not, since this  
property is bound to the column renderer).  This one is currently part of  
my app, not of cells-gtk, but it would be quite easy to integrate it in  
cells-gtk.

Comments welcome!

Peter
