This seems to be an amazing idea, and probably extremly long to implement... So let's do some analyzing: 1. We need to implement a check grid. This seems to be pretty simple using a GtkTable (if we pick the simple way), or if we use a GtkTreeView (which can actually show a table) with GtkCellRendererToggle. 2. The painting of the matrix as showed in the specifications seems very hard, and I doubt it worths it. We can easily implement different colors for each row, and users will have to settle for a little border between the columns. If we agree to give up the proposed matrix painting and choose what I suggested, it can be done with GtkTreeView without any special changes, but it will leave the simpler GtkTable our of the question (which is fine with me). 3. Adding the images with the link's color should be a bit tricky, but I assume that it can be done dynamically (by drawing those images after acquiring the link's color, instead of embedding ready bitmaps). 4. Popup window: Part 1 - the curves widget. This can definetly be stolen from the curves tool, no need to work twice. The only needed modification is that we can show some other curves at the background, and that we add min and max arrows. 5. Popup window: Part 2 - switching the tabs. This doesn't seem to bad, especially since we already have similar functionality in the curves tool. only two things seem problomatic: A treeview widget can't have a bitmap in it's header, And adding the bitmaps as the first row is ugly and probably not the right way to do this. The guys on the GTK mailing list will probably be able to help us out here. And another questions is, why do we have the same header images at the bottom? Adding a footer to a GtkTreeView isn't possible. Do we really need that? Here i'm defintly sure it's not worth the coding amount that it will require, and I personally find it confusing. I haven't seen anything that scary in here, but I doubt that I'll have time to touch it in this month. If I implement something like this on a dummy GtkWindow (instead of hacking GIMP's source code, which I don't excel at) as a stand-alone Gtk application, will it help? If so, I'll try to give it a shot. If you want to see how to use the TreeView and the CellRenderer, the gtk-demo program (which comes with GTK) has a nice example under "Tree View/List Store". The code is very simple and in one of the columns you'll see the Toggle renderer. > for example, one dock needs to hold 2.5 distinct views I haven't understood that sentence. Can you please explain (or, have I referred to it already)? Just one offtopic comment: Some of the icons seem very unintuitive - even as an "old" GIMP user I'm still confused by the fifth one from the left. What does it stand for? ~LightningIsMyName _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
