## Description

GtkSheet is a matrix widget for GTK+. It consists of an scrollable grid of cells where you can allocate text. Cell contents can be edited interactively through a specially designed entry, GtkItemEntry. It is also a container subclass, allowing you to display buttons, curves, pixmaps and any other widgets in it.

You can also set many attributes as: border, foreground and background color, text justification, and more.

The testgtksheet program shows how easy is to create a spreadsheet-like GUI using this widget.
