Now we are ready to start building our Gnome interface. We first need to create our main Gnome Application Window which will be the window displayed when our application starts up. Select the Gnome button of the Palette window to display in the palette the Gnome widgets (which are extensions to the GTK+ Basic widgets which are displayed by default). Identify the Gnome Application Window widget by hovering the mouse over the various widgets to display their tool tips. It is the top left widget in the palette. Simply click on it with the left mouse button to create one.
There are many other widgets available on this Gnome palette. They include dialog boxes, message boxes, a standard Gnome About Dialog, file entry field with a browse button, a pixmap entry field with built-in preview, and a druid. We'll see some of these later and
all of them in the reference sections. For now we simply create the Gnome Application Window.
