Question about ttk_checkbutton widget
in [TCL]

From: Emiliano on 7 May 2010 19:28 Widget states are pretty different on ttk than the ones on plain Tk. See http://www.tcl.tk/man/tcl8.5/TkCmd/ttk_widget.htm#M22 The easiest way to obtain the behaviour you want is turning off all widget bindings set var 1 ttk::checkbutton .cb -variable var -onvalue 1 -offvalue 1 pack .cb bindtags .cb {NONE} The .cb checkbutton will not respond to any of the standards bindings, behaving as read only. However, it still reflects the value of the associated variable. Emiliano

It can, but that doesn't have any effect. The preferred way to change the state of ttk::* widgets is with the [$w state] command (the "-state" option is only present as a compatibility shim). However, ttk::checkbuttons and radiobuttons don't support the "readonly" state, so [$cb state readonly] won't work anyway. The best way to get an "output-only" checkbutton (or to change the behavior in general) is to use a different widget class: [ttk::checkbutton .cb -class ROCheckbutton] Then add the appropriate bindings for the ROCheckbutton bindtag. In this case, there are none, so do nothing :-) --JE
