nanogui: Thread: Nano-X, nxlib, FLTK and 1bpp

Hello everybody!

I'm developing an ARM based emdedded application with 1 bpp monochrome lcd. 

Nano-X alone is working fine in it but I would like to use Nano-X, Nxlib and
FLTK. I've been trying to make them work by grepping through Nxlib and just
allowing the 1bpp cases but without success. I am using versions 0.91, 0.45
and 1.1.6.

I've managed to get something out of them. For example Fl_Light_button draws
out fine with flat_box and without changing its colors. If I change its
color to black or white, it doesn't work anymore. With some widgets I can
draw only text and for example with Fl_Button I can draw only borders. 

What can be wrong and what can I try to do to make it work?

Thank you for help in advance!

Best regards,
Mikael

There isn't any support for NXLIB for color schemes less than
8bpp.  It can be added, but you'll have to painstakingly go through
each file and add support.  The biggest issue could be conversion
routines for the Xlib Get/PutImage stuff...  which was why it
wasn't added in the first place.

In addition, I don't know whether FLTK supports 1bpp, you'll
have to check with them on that.

I checked from the FLTK mailing list that FLTK needs 16 colors in palette
format, but it could work with 1bpp by creating own box types etc.

If I can't get Nano-X, Nxlib and FLTK working in my device, what options is
there? Does FLNX support 1bpp? I tried to access the public ftp-site in
Pixil.org to get FLNX but I couldn't get in. Is it up and running? If not,
where could I get FLNX?  

I found also a widgetset for Nano-X called TinyWidgets. What is it's status?

Thanks!

FLNX is basically a very early version
of FLTK.  FLNX is now bundled with www.pixil.org code.

I'm not sure whether FLTK/FLNX support 1bpp or not,
since I stay away from most C++ code.

It's not very complete, but basically works.

What complexity of widget set do you require?

TinyWidgets is pretty close to my needs for now but in future my needs will
probably be closer to FLTK or some other more complex set. So, I'm still
intrested in Nxlib/FLTK combination or some other more complex widget set. 

What's your estimate of work to be done in time to make Nxlib work with 1
bpp?

And is there still development going on with TinyWidgets? Or is there some
other widget set to be considered?

Thanks!
