1. Overview
GnomeArt(2f)Tutorials(2f)GtkThemes(2f)GtkNotebook/screenshot.png "screenshot.png")
Notebook can also be used without extensions. Then they will not draw anything, and don't have any padding around themselfs. This is used for wizards (druids) and some other cases.

3. Geometry
GnomeArt(2f)Tutorials(2f)GtkThemes(2f)GtkNotebook/tab-geometry.png "tab-geometry.png")
tab-hborder and tab-vborder are properties of ../GtkNotebook and cannot be modified by the theme. The default value is two pixel.
4. Drawing
The main notebook is drawn with BOX_GAP, detail is "notebook", state NORMAL and shadow OUT. The extensions are drawn with the EXTENSION function. The selected extension has state = NORMAL and the others state = ACTIVE. The detail for the extension is "tab" and the shadow OUT. The extensions are drawn from right to left except for the selected one which is drawn last. It needs to be done this way so that overlapping works correctly.
The focus for the tabs is drawn with a detail of "tab". The state works the same as the one for the extensions. (Only the selected tab can have the focus, so state will always be NORMAL I think)
5. Bugs
Some versions of GTK+ 2.10 had a bug, which caused all notebook tabs to be the same height. (gnomebug:353962)
