jhbuild setup

All the changes have been landed in the master branches. Make sure you have the sugar-toolkit-gtk3 repository checked out and installed. There has been a fix in pygobject. Either compile/install the master branch or in F16 you can install as well the recent pygobject3 release.

Pending work

• shortcuts in palettes: button tooltips should show the shortcut, if any, next to the tip. Like in the Stop button, "Stop Ctrl+Q"
• title in menus (e.g. 'Back' in the Browse back button palette)

sugar-toolkit-gtk3

• take screenshot: the code has to be ported to cairo, see _get_screenshot in Browse as an example
• toolbars: finish the sub-toolbar look-alike like in gtk2
• finish porting the 'do_expose_event' calls to 'do_draw' calls

sugar-artwork

• deprectate icon-slicer
• finish the theme

Pending upstream work

All of these have been worked around (or will be worked around) for now, at the sugar level.
