Question

Accepted Answer

This section covers icon-variable display and progress bars: filtering the icon background color (the filter samples the first pixel at the top-left corner and removes identical colors; if filtering fails the background is not pure - zoom in with Paint to check); multiple buttons driving separate icons (method 1: set icon widget addresses all to 0x1001 with key values 1/2/3 aligned to upper/lower limits; method 2: bit-variable icons); progress bars (method 1: 100 icons from 0-100, icon area limited to 255x255, max 1023x1023 supported, best for circular bars; method 2: image animation; method 3: cut the progress bar by coordinates and use rectangle fill command 5AA5+length+82 000500040001+top-left+bottom-right+F800; for 0-100 map each unit to 4 pixels when the x span is 400).
