Where is the Tab Widget

[Reed Lai <reed aga-inst com>]

Hi,

Does GTK have tab widget? I found the ability from many GTK/Gnome apps -
gedit, gnome-terminal, Gnumeric and GIMP's stacked dialogs, but I can
not find Tab Widget from GTK's tutorial and API reference. What the
widget should I use to make it?

Sorry for my bad English. Follow is 3 piled tabs open and the tab1 is
active.

+------+------+------+
| tab1 | tab2 | tab3 |
| +-----------------------+
| |
| |
| |
| Tab client (content) |
| |
| |
| |
+------------------------------+

Thanks!
