I think the 'fltk' graphics library is quite lightweight. We still use that instead of qt and gtk on limited embedded platforms simply because it takes 1.2 MB or a bit more rather than a full blown Qt with 10-12+ MB. If I understand correctly there were discussions that gtk should not be inside openembedded core which I agree about. However, I think it would be useful to have some lightweight library like this in. Of course, this is lacking some features that Qt has, but that is why it is lightweight after all. :-) It is currently in the openembedded layer. It has a couple of minor dependencies which should probably be moved, but I do not see anything major. I think it is a more "core" option for ui building than the alternatives. This also supports opengl to a certain extent. Cheers, Laszlo [-- Attachment #2: Type: text/html, Size: 1005 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread

Shall I take it as "No"? The lack of responses does indicate that its not something there is strong support for so I don't think fltk will be moving, correct.

Currently, I do not see any minimal gui library in openembedded core for building some simple GUI on real embedded devices, but OK. ^ permalink raw reply [flat|nested] 6+ messages in thread

For example, the fact that is used in a lot of OSS. A very good demo of the possibilities of FLTK is Giada, "A Hardcore Loop Machine" http://www.giadamusic.com/ In my opinion, it is one of the best looking apps written using FLTK for the graphical interface. Also, judging from the screenshots, I think it should be interesting to use it with a touch interface. However, I don't have any info regarding how well FLTK behaves in this aspect. Example screenshot: http://www.giadamusic.com/screenshot-09 Also, while Giada looks complex and with a lot of functionality built-in, the source code seems neat and tidy, which might be an argument regarding the fitness of FLTK in the embedded space. Giada's authors takes pride of the facts that the source code contains around 100 files and has around 30KLoC. Now, in my opinion, what is a little bit "strange" regarding FLTK is that it doesn't "fit in", because it doesn't have a native look'n'feel on any of the supported platforms. But that's not really an issue in an embedded device, where FLTK might power up the only GUI needed for that particular device.

The demo is very impressive, and as you say, "native theme and look" does not matter much on real embedded device, i.e. not generic computing mobile platforms - that are more powerful than some of the old, but still existing desktop machines - with its own UX design guide... Basically, the theme is what you define is, so I do not see issues in there. :-) In my experience, you would try hard to avoid X or even wayland on such devices in favor of framebuffer, etc. The problem, I see, I would need to grab a somewhat large "oe" layer to make a minimal UI on a real embedded device. That is not going to happen any soon. I would rather maintain my own fltk recipe in our layer instead. As for the touchscreen, yes, I would be actually interested in using fltk for touch screen devices. In fact, I already have some code, so I am just looking into the option to get the necessary libraries deployed by the Yocto project and openembedded-core. If you ask me, and I can throw my two cents in, qt and gtk are lotta more heavy and should not have made their way into oe-core IMHO, but perhaps it is only there for compatibility now. I mean, I would be fine with any good lightweight libraries on oe-core for creating minimal touch guis and that kind on minimal embedded devices, but I currently see no other option than writing your own ui kit with raw opengl, perhaps using glew from oe-core, etc. Suggestions would be welcome. I think oe-core could have this responsibility, but I will leave that with the maintainer... Cheers, L.
