100 * GtkProgress/GtkProgressBar had serious problems in GTK 1.2.
102 * - Only 3 or 4 functions are really needed for 95% of progress
103 * interfaces; GtkProgress[Bar] had about 25 functions, and
104 * didn't even include these 3 or 4.
105 * - In activity mode, the API involves setting the adjustment
106 * to any random value, just to have the side effect of
107 * calling the progress bar update function - the adjustment
108 * is totally ignored in activity mode
109 * - You set the activity step as a pixel value, which means to
110 * set the activity step you basically need to connect to
112 * - There are ctree_set_expander_style()-functions, to randomly
113 * change look-and-feel for no good reason
114 * - The split between GtkProgress and GtkProgressBar makes no sense
117 * This was a big wart on GTK and made people waste lots of time,
118 * both learning and using the interface.
120 * So, I have added what I feel is the correct API, and marked all the
121 * rest deprecated. However, the changes are 100% backward-compatible and
122 * should break no existing code.
124 * The following 9 functions are the new programming interface.
