# Part III. Porting Applets from GNOME 2.x

## Porting a D-Bus-based Applet

There is no major issue porting a D-Bus-based applet from GNOME 2.x, from a Panel Applet library perspective. It is actually likely that the main issues will be that the applet has to be ported to GTK+ 3. Please refer to the GTK+ 2 to GTK+ 3 migration guide for this.
