Writing Your Own Widgets


Although the GTK distribution comes with many types of widgets that should cover most basic needs, there may come a time when you need to create your own new widget type. Since GTK uses widget inheritance extensively, and there is already a widget that is close to what you want, it is often possible to make a useful new widget type in just a few lines of code. But before starting work on a new widget, check around first to make sure that someone has not already written it. This will prevent duplication of effort and keep the number of GTK widgets out there to a minimum, which will help keep both the code and the interface of different applications consistent. As a flip side to this, once you finish your widget, announce it to the world so other people can benefit. The best place to do this is probably the gtk-list.
