Check buttons#
Turning visual elements on and off with check buttons.
This program shows the use ofCheckButtons which is similar tocheck boxes. There are 3 different sine waves shown, and we can choose whichwaves are displayed with the check buttons.
Check buttons may be styled using thecheck_props,frame_props, andlabel_propsparameters. The parameters each take a dictionary with keys of artist property names andvalues of lists of settings with length matching the number of buttons.
