Hi,
one of the time consuming activity with the display, is the layout design, especially for diagonal line o complex design.
Someone know if exists a freeware program to design the layout and capture the coordinates to be used into the directives (rectangle, line, circle, etc) to insert into the .ino files?
thank,
M.
Microsoft Paint set to the resolution of the display and zoomed does the job surprisingly well
You can draw lines, circles, boxes and read the cursor coordinates from the screen for use in your sketch

Design your GUI with a drag & drop builder, then apply the same code to a wide range of displays
Thanks UKHeliBob,
it works perfectly 
Hi rtek1000,
it's a very interesting tool, I have download the latest version (0.17.b11) for Windows, but have some problem to save the project.
I am glad it works for what you want to do
I assume that you know the Paint keyboard tricks such as holding down the shift key to ensure perfect horizontal, diagonal and vertical lines, perfect circles and square boxes etc
Yes sure, now I know
