Getting Graphic

If you're looking for even more graphics for your interactive scripts, you can go one step further. Both the KDE and GNOME desktop environments (see Chapter 1) have expanded on the dialog command idea and include commands that produce X Window graphical widgets for their respective environments.

This section describes the kdialog and zenity packages, which provide graphical window widgets for the KDE and GNOME desktops, respectively.

The KDE environment

The KDE graphical environment includes the kdialog package by default. The kdialog package uses the kdialog command to generate standard windows, similar to the dialog-style widgets, within your KDE desktop. However, instead of having the clunky feel to them, these windows blend right in with the rest of your KDE application windows! This allows you to produce Windows-quality user interfaces directly from your shell scripts!
