Arguments: outline

Returns the value of the select-on-right-click property of an outline control. The value may be set at creation time by passing the :select-on-right-click initarg, or any time later by calling (setf select-on-right-click).

If this outline property is true, then right-clicking the widget will select the outline-item under the mouse before doing any other right-click behavior. If nil, it will not.

The default value is nil. It may be useful to set this property to true if, for example, you would like the user to be able to right-click an outline-item to both select that item and to pop up a menu whose commands would be applied to the selected item.

Other right-click behavior for an outline might be implemented in a mouse-right-down or shortcut-commands method for the associated outline-pane. If this property is true and there is a shortcut-commands method for the outline-pane, then the pop-up-menu will be positioned just below the selected outline-item.
