push-button WidgetSyntax:
type ::= (push-button [keyword argument]... [ value ])
A widget that acts as a pushable button. Its super is the item
widget.
The value, if present, is used to initialize the :value
property. The value should be a string, which will be inserted in the
buffer.
By default, it has the following properties:
:button-prefixThe empty string.
:button-suffixThe empty string.
:value-createInserts a representation of the “on” and “off” states for the push button.
The representation might be an image, stored in the :tag-glyph
property, or text. If it is text, it might be the value of the
:tag property, or the :value of the widget, surrounded
with widget-push-button-prefix and
widget-push-button-suffix. See Customization.
:formatButtonizes the widget, to make it clickable.
