ttk::checkbutton pathName ?options?
A ttk::checkbutton widget is used to show or change a setting. It has two states, selected and deselected. The state of the checkbutton may be linked to a Tcl variable.
|Name||Database name||Database class|
|A Tcl script to execute whenever the widget is invoked.|
|The value to store in the associated -variable when the widget is deselected. Defaults to 0.|
|The value to store in the associated -variable when the widget is selected. Defaults to 1.|
|The name of a global variable whose value is linked to the widget. Defaults to the widget pathname if not specified.|
In addition to the standard cget, configure, identify, instate, and state commands, checkbuttons support the following additional widget commands:
The widget does not respond to user input if the disabled state is set. The widget sets the selected state whenever the linked -variable is set to the widget's -onvalue, and clears it otherwise. The widget sets the alternate state whenever the linked -variable is unset. (The alternate state may be used to indicate a "tri-state" or "indeterminate" selection.)
Ttk::checkbutton widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.
