I looked at porting to the libgimpui previews but the documentation wasn't clear to me (not that its bad - I just didn't quite get it right off the bat). After thinking it over a bit I realized that carrying around the object weight of a widget wasn't really necessary for my purposes. So far, only two of the plug-ins use previews: GFXTrans and GFXLayers. The former *could* use the libgimpui preview but zooming and panning really aren't necessary for this plug-in. I just need a thumbnail to shove in the middle a drawing area. Take a look at the plugin and you'll see what I mean. I'm not modifying the layer content, I'm just doing a transform on it. And the preview doesn't get updated with the interactive transform. Its a hacky solution, but I did it originally before the much nicer builtin in transforms for 2.x came out. It's only real advantage is allowing you to do multiple, identical transforms into multiple layers. GFXLayers is much more intense - it used to carry a gimppreview (this was the old gimppreview code that floated around a while back) for each layer, sans zooming/panning features. These were stuffed in a GtkFixed widget and moved around by the user. GtkFixed isn't recommended for new applications according to the GTK+ 2.6 docs, and that's when I realized I really didn't need widgets if GIMP could just pass me the right sized pixbuf - which it now does. Again, I just need a very small thumbnail to represent the layers. In fact, there is an option to turn off the previews if that gets too confusing (which it can be if you have a *lot* of layers). That came about because it got really slow in the old version with lots of layers using the older gimppreview code I had. Additionally, the weight of carrying around widgets for all those layers is overkill for this plugin. I just need a simple pixbuf for each layer. So, it's nothing against the gimppreview widgets - these look and perform fine in all the stock plugins. It's just that the gimppreview widgets provide far more than I really need. This is all just one design perspective, of course. I'm open to suggestions on making these plugins better. -- Michael J. Hammel The Graphics Muse A hard-on doesn't count as personal growth.
