nanogui: Thread: Re: Nano-X issue

Albert - 

You'll need to read up or post on the FLTK list, as you're using the FLTK
toolkit to set up text and colors.  Check to see that the colors are
in fact changing when running on FLTK/X11, instead of through the
NXLIB library.  I have tested nano-X with FLTK 1.10 and all the FLTK
demos run fine.

Regards,

Greg

  Subject: Nano-X issue


  Dear Sir,

   

  The following code is to display text "Hello World!" on TI 365 platform,

  The development environment uses Nano-X(v0.92) and FLTK(v1.07).

   

  Questions:

   1. Cannot change the text size, even modify box->labelsize();

  2. Cannot change the background and text color after modifying the relative attribute. The background is always blue and text is black.    

   

   Would you kindly tell how to set/check font, color, size in Nano-X library ?

   Please give me a hand.

   Thanks a lot.

   

   int main(int argc, char **argv)

  {

    Fl_Window *window = new Fl_Window(340,180);

  Fl_Box *box = new Fl_Box(20,40,300,100,"Hello, World!");

    box->box(FL_UP_BOX);

    box->labelfont(FL_BOLD+FL_ITALIC);

    box->labelsize(10);

    box->labeltype(FL_SHADOW_LABEL);

    window->end();

    window->show(argc, argv);

    return Fl::run();  

  }

Albert - 

I'm not sure I understand exactly what you're looking for, but
you'll need to write code in FLTK, not nano-X.  I'm not very
expert in FLTK, so you might ask your questions on their list,
as they are familiar with changing colors with FLTK.

With regards to running FLTK/Nano-X on PCs, it was a suggestion
as its very easy to compile and run FLTK and nano-X on PC Linux
platforms, just for test purposes.  You might also look at the
FLTK demo directory and demos in order to find sample source
code to do what you want.

Regards,

Greg

  Dear Greg,

   

   How are you ?

   

   Thanks for your kindly answer and test.

   As we use FLTK/NANO-X on TI DM365 Platform (Embedded Linux System), not on PC.

   

   We can use FLTK/NANO-X to put Image on some point (x,y), IR and Mouse can work on TI Platform successfully. 

   

   In order to display “Wordings with different color & size” (OSD) in Linux booting time, it lets users know our device’s status.

   We encounter this kind of problem. And your help is very appreciated.

   

   Can you give us some idea on how to check something between Nano-X and HW’s initialization (Color Plate, Font Selection, Word Size) ?

   

   Have a good working day.

   

   Best Regards,

   

  Albert Chen

Dear Albert,
  I had similar issue with nano-X and FLTK for fonts all fonts worked
in PC for the same a FLTK app but in hardware with nano-x it displayed
only one font and one size in-spite of any font selection.

I found the problem was in fonts installation make sure you have all the fonts
the systems fonts director (/usr/share/fonts) and these dirs also is
in fontslist.c in nano-x.
Hope this helps

My working environment is
1) in PC   MyApp / FLTK / X11
   In PC everything worked fine
2) in Hardware MyApp / FLTK / NX11

I had issues in different fonts and font size. I suspected NX but
after adding appropriate fonts in the hardware system directory my
problem got solved.

Regarding background color I have no Idea but it should be your fltk
issue may be I can try to help you if you can share your part of that
code.
But again as Greg said it should be discussed in a FLTK forum

Albert,
be also sure to have fonts support (freetype2 ?) compiled-in in your FLTK and Nano-X build.
