Try this....

without warning
include Win32Lib.ew
constant rectX = 600, rectY = 400
constant win = create(Window, "Draw Line", 0, 0, 0, rectX, rectY, 0)
constant canvas = create(Pixmap, "", win, 0, 0, rectX, rectY, 0)
---===---===---===---===---===---===---===---/   procedures (START)
procedure onStart()
 setPenColor(canvas, Black)
 drawRectangle(canvas, True, 0, 0, rectX, rectY )
 setPenColor(canvas, Blue )
 setPenStyle(canvas, Solid )
    drawLine(canvas, 10, 100, 300, 300 )
end procedure
    onOpen[win]=routine_id( "onStart" )

procedure Paint(integer x1, integer y1, integer x2, integer y2)
 copyBlt(win, 0, 0, canvas)
end procedure
    onPaint[win]=routine_id("Paint")
