Features/GTK3/Shell/GTK3 Port

Manuq started the port of the shell branching the hippo removal. The main issues were identified by Daniel Drake some months ago and fortunately most of them are fixed at this point.

Daniel Narvaez set up a sugar-build branch to make the port. To test:

 git clone git://git.sugarlabs.org/~dnarvaez/sugar-build/manuqs-shell-port.git

Current issues

• journal does not start
• control panel does not open, crashes sugar
• home, list view not being displayed
• menu palettes are blinking
• launch screen does not go
• activity icon in the frame does not stop blinking
• keybindings do not work
• buddy icon in home view and network view is some pixels above the center (maybe because is being set in the wrong grid cell)
• the corners of the frame have grey color
• widgets like icons and texts have grey background instead of black (toolbar-grey) - this is because of a change in gtk (seen in Browse too)
• home, favorites view, random layout, can't drag icons
