VtRadioBox(VTCL)

Synopsis

Description

Options

-autoSelect boolean (CS)

Works only in character mode. If autoSelect is True, buttons within the radiobox are automatically selected when traversing to them. The selection follows the focus when moving between radio buttons with the arrow keys. This provides behavior equivalent to the Microsoft^® Windows radiobox. The default is False.

-callback cmd (CS)

Sets the cmd called when a toggle button in the radiobox is selected. This overrides any callback set for the contained toggle buttons.

Additional callback keys:

selectedWidget

selected toggle button

value

selected toggle button

-noCallback (CS)

Suppresses the -callback when -value is set.

-textVariable string (CS)

Updates the interpreter variable string with the widget value. The update happens under the same conditions that would invoke -callback, but before -callback is called. Setting a value into the interpreter variable updates the RadioBox as if setting -value on the widget.

-value widgetName (CSG)

Turns on the widgetName passed in toggle button. To use this option, also set -noCallback.

• ``Geometry class options'', if the widget's parent is a form.

• ``Object class options''

• ``RowColumn class options''

Return values

HAS_CALLBACK

already has callback, trying to set callback when one already specified

NO_CHILDREN

NO_VALUE_SET

specified -noCallback without setting -value

NO_WIDGET

no widget corresponding to widgetName given
