A [Tk] (or rather [Ttk]) [widget] that stacks a bunch of widgets on top of each other in a window, with some tabs at the top to allow users to select between the widgets. A common idiom in Windows's Properties dialogs. : http://www.tcl.tk/man/tcl8.5/TkCmd/ttk_notebook.htm ---- A [notebook] may be used as a '''pages manager'''[http://wiki.tcl.tk/17852] by using a style to turn off the tabs, like this (by [Joe English]): style theme settings default { style layout Plain.TNotebook.Tab null } ttk::notebook $nb -style Plain.TNotebook ---- [tonytraductor] I have a question. Using a ttk::notebook, how do I pass the currently selected tab's info to a process? Answer: [[$nb select]] returns the widget name of the currently selected pane. In addition, the string "current" may be used as a tab identifier. ---- !!!!!! %|[Category Widget]|% !!!!!!
