Yair Altman (3 days 17 hours ago): The default Java Look&Feel for UI buttons paints the border together with the contents, and apparently prevents changing both of them together (reference). Changing to a...
Jacob (4 days 3 hours ago): So, I’m having trouble finding information on this. If I change the border of a button, then change the background color, the border resets. Then I am not able to change the...
Sky (6 days 10 hours ago): Matlab seems to catch on to mustBeMember and offers tab completion options when it is used. classdef foo < matlab.mixin.SetGet properties Coordinates {mustBeMember(Coordinates,{...
