with GWindows.Application;

with GWindows.Windows.Main; use GWindows.Windows.Main;

with GWindows.Drawing; use GWindows.Drawing;

with GWindows.Colors; use GWindows.Colors;



procedure Pixel is

   Window : Main_Window_Type;

   Canvas : Canvas_Type;

begin

   Create (Window, "Pixel", Width => 400, Height => 200);

   Get_Canvas (Window, Canvas);

   Show (Window);



   for X in 10 .. 190 loop
