mode
Description:
The mode property determines the way LevelBar interprets the value properties to draw the level fill area.
Specifically, when the value is CONTINUOUS, LevelBar will draw a single block representing the current value in that area; when the value is 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 min_value and max_value.
