The Glade interface designer enables you to create and edit user interface designs for GTK+ applications.

The GTK+ library provides an extensive collection of user interface building blocks such as text boxes, dialogue labels, numeric entries, check boxes, and menus. These building blocks are called widgets. You can use Glade to place widgets in a GUI. Glade allows you to modify the layout and properties of these widgets. You can also use Glade to add connections between widgets and application source code.

The user interfaces designed in Glade are stored in an XML format, enabling easy integration with external tools. You can use the libglade library to dynamically create GUIs from the XML description.
