I want a widget that is the combination of GtkComboBoxEntry and GtkEntryCompletion that can display a tree of options in a nice, indented way without the expanders (but with the rows expanded). Basically, a search box with a drop-down and hierarchical entries. I think I'm going to have to write my own, thought it sounds like something that might be more widely useful than just my application.


Visited nixwilliams and daniel_bethany for a cup of tea, which become lunch (which was delicious) which became more tea, which became waiting out the rain and watching Nicholas Crane trip over a lot. Got wet going home anyway. Now waiting out the rain again before going to the shops. It's a good thing that I like rain; though mostly I like wearing a giant, warm jumper while it rains outside.

Some time ago I wrote about my work on Clutter-GTK. Well, I finally got around to rebasing this branch so it could be merged and ebassi merged it for me last night.

There are still bugs in the code that I've not fixed, but many eyes make all bugs shallow, right?

The code includes a number of examples of how to do things.

If you're going to use these classes, you should understand how they work. There are caveats. Certainly I wouldn't base your entire toolkit around the interchanged use of GtkClutterActor and GtkClutterStandin.

GtkClutterActor takes a GtkWidget, rendered offscreen to an XPixmap, and paints it onto a GL texture which it draws on the Clutter stage. As a result, it can draw that texture anywhere, at any stacking level, and do things like taking events and sending them back to GTK+. Updating of the offscreen pixmap is done using Damage events, and things are generally peachy.


Things basically work like you expect. Although there are some performance issues where widgets that draw using two expose events will sometimes have a delay between the two Damage events that I've not yet explained, which can cause a visual rip.

If GtkClutterActor lets you embed a GtkWidget into a Clutter stage, then GtkClutterStandin goes the other way around, allowing a ClutterActor to be placed within a GtkContainer; but the implementation is different. The ClutterActor is not rendered into offscreen memory, and then copied into an XPixmap and blitted into GTK+, this would now allow for all of those exciting animations you want to do.

Instead what happens is that GtkClutterStandin reserves space within a GtkContainer for the actor it proxies and then places that actor on top of the texture containing the widget contents.

Bugs should be filed in the Opened Hand Bugzilla.

So very often I find myself trying to find the name of an icon in the icon theme, and I end up having to search through my icon theme with a combination of find and eog. Usually I miss the icon on my first pass through.

Today I cracked, and decided to hammer together a quick and dirty viewer and searcher for the icon theme which looks something like this:


It's written in PyGTK and so far only has the single feature of 'Search' (this is my 90% case). It could be a lot more advanced if people wanted to hack on it: it could select themes, show whether an icon is in this theme or a parent theme, what sizes are available, etc. I will certainly accept patches!

Hopefully other people find this useful too. Source code is here.
