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