: I'm trying to find if there is a way to create rounded rectangles and
dotted lines using nano-X
Ah, the old round-rect and dotted lines problem, heh?
I'll bet you're trying to get a focus rectangle.
I have planned for rounded rectangles in Nano-X for
some time, but hadn't quite finished them. I did implement
them for win32 however, and the routines use the same
engine region routines already in nano-X. Take a
look at CreateRoundRect in src/mwin/winrgn.c, you
should be able to port that to Nano-X in an hour or
so. (You could choose to run this as user code,
calling the GrXXX region routines, or put it in
nanox/srvfunc.c and call the GdXXX region routines.)
Dotted lines are another problem that really isn't
part of the current engine code. My suggestion is to
code up a special dotted line round rect by using
the above suggestion, and adding a pixel-skip hack
in order to get the focus rect.
I have in the back of my mind some ideas for dotted
line drawing and wide lines, but it's been lower priority.
Regards,
Greg
