gtk:toggle-button-inconsistent (object)

object -- a gtk:toggle-button widget
setting -- true if state is inconsistent

Accessor of the inconsistent slot of the gtk:toggle-button class. If the user has selected a range of elements, such as some text or spreadsheet cells, that are affected by a toggle button, and the current values in that range are inconsistent, you may want to display the toggle in an "in between" state. This function turns on "in between" display. Normally you would turn off the inconsistent state again if the user toggles the toggle button. This has to be done manually, the (setf gtk:toggle-button-inconsistent) function only affects visual appearance, it does not affect the semantics of the button.
