Application Indicators
At Openismus I am currently supporting Canonical to implement Application Indicators for Ubuntu Lucid. Application indicators are simple menus so it is easier and more consistent to interact with them than with the current notification area icons, where each icon behaves differently. Some are showing different popup menus on left and right click, others are [...]

Instead a scrollable widget is defined by a “set_scroll_adjustments” signal, which id is written to the GtkWidgetClass::set_scroll_adjustments_signal class variable.
