> 1 - Does FLTK supports Russian language?
That depends: There are three possible cases. Russian is relatively straightforward however, since is coded LtoR like a Latin alphabet (e.g. ASCII) so is much less tricky than a Semitic alphabet (Hebrew, Arabic) for example. i) Using fltk-1.1.9 This will display the Cyrillic glyphs, IF the correct "code page" is set on the target machine, AND a font is loaded that correctly supports the selected "code page". However, it is hard to ensure that the correct "code page" is set, and there isn't a really a portable way to ensure that the correct code page and font are selected at runtime for your app. So, it may work perfectly on your machine, but then display all the wrong glyphs when run on some other machine... Which is exactly why we have Unicode. Which brings us to: ii) Use a patched version of fltk-1.1.x that knows about Unicode (encoded as UTF-8) and load a Unicode font that supports the Cyrillic glyphs. Many fonts have names like "something-LGC.ttf" for example, where the LGC means that the font has support for the Latin, Greek and Cyrillic Unicode pages. (Very few Unicode fonts are "pan-fonts", i.e. including all the Unicode font pages, because they become huge...) My patched version of fltk-1.1.8 is at: http://www.9edgedown.talktalk.net/fltk/fltk118-utf8-2008-02-24.tar.bz2 There are others out there, Google will probably find something. I don't have a patched version of fltk-1.1.9, but the plan is for UTF-8 support to be built into fltk-1.3 in the near future. iii) Use fltk-2. It has some small stability issues, but is already UTF-8 aware, and so should "Just Work" for you. > 2 - Is it posible in FLTK to fill round rect with a pattern? Not sure what you are asking here...? > 3 - Is it possible to make round button in FLTK? You can very easily subclass your own button widget and draw pretty much anything you like, so yes, this should be easy, if the built-in round button types are not to your taste. Another option is to use a pixel map image for your button, that can be look like any shape you like. Greg has a worked example here that might help: http://www.seriss.com/people/erco/fltk/Fl_Gel_Tabs/ And my take on Greg's example is here: http://www.9edgedown.talktalk.net/gel_buttons.html SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
