Detailed Description

KURLBar is a widget that displays icons together with a description. A URL-bar widget, as used in the KFileDialog.

They can be arranged either horizontally or vertically. Clicking on an item will make the activated() signal being emitted. The user can edit existing items by choosing "Edit entry" in the contextmenu. He can also remove or add new entries (via drag&drop or the context menu).

KURLBar offers the methods readConfig() and writeConfig() to read and write the configuration of all the entries. It can differentiate between global and local entries -- global entries will be saved in the global configuration (kdeglobals), while local entries will be saved in your application's KConfig object.

Due to the configurability, you usually only insert some default entries once and then solely use the read and writeConfig methods to preserve the user's configuration.

The widget has a "current" item, that is visualized to differentiate it from others.
