The #GtkLevelBar:mode property determines the way #GtkLevelBar interprets the value properties to draw the level fill area. Specifically, when the value is #GTK_LEVEL_BAR_MODE_CONTINUOUS, #GtkLevelBar will draw a single block representing the current value in that area; when the value is #GTK_LEVEL_BAR_MODE_DISCRETE, the widget will draw a succession of separate blocks filling the draw area, with the number of blocks being equal to the units separating the integral roundings of #GtkLevelBar:min-value and #GtkLevelBar:max-value.
