gtk:widget-direction (widget)

widget -- a gtk:widget object
direction -- a value of the gtk:text-direction enumeration

Gets or sets the reading direction for the widget. This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitely visual rather than logical, such as buttons for text justification.

If the direction is set to the :none value, then the value set by the gtk:widget-default-direction function will be used.
