shiva_crazy02 · #1 10-Apr-2008, 09:58

Dear all,
I am new in fluid of fltk.
I compiled it on my machine (Linux platform).
Now I want to make one application.
It should look like

Display ______________________

( button 1 ) ( Button 2)

when I pressed button 1 it should print "you pressed button 1" in Display,same function for Button 2.

Help me .....
thanking all of you

Dear all and admin ,
You did not reply simple post.
I tried little bit .........cable_guy tutorial help me .......
here is my program .....details of all files generated by fltk are:-

My dis.fl is :-

Code:

# data file for the FLTK User Interface Designer (FLUID)

                                        Fl_Input *i=(Fl_Input*)userdata;
                                        i->value();

}
else if(userdata=="u pressed shiva") {
"dis.fl" 65L, 1335C

"my dis.h file is"

}
}

int main(int argc, char **argv) {
  return Fl::run();
}

I compile it by @fltk2-config --compile dis.cxx and I tried g++ option also .......It is giving error as :-

Code:

please help me dear .....
Thanking all of you

cable_guy_67 · #4 12-Apr-2008, 06:21

I don't use fltk2.0 but is there some reason you have a mix of 2.0 and 1.1 code in there? Is that what Fluid 2 is outputting?

If I can get 2.0 to build I'll see what I can do but until then hopefully someone can help you out.

cable_guy_67 · #5 12-Apr-2008, 09:14

Just as I thought, 2.0 is in an uncompilable state (by me with cygwin anyhow) at present. I could give it a try with an old revision (5973 in subversion) but it most likely wouldn't work for you.

Instead, I'll show an example for fltk 1.1.9, which is the current working version in subversion. It should also work the same with 1.1.8final which is the stable release.

Fluid file :

Code:

# data file for the Fltk User Interface Designer (fluid)
version 1.0300 
header_name {.h} 
code_name {.cxx}
Function {buttonCB(Fl_Button*o,void*data)} {private
} {
  code {display->value(o->label());} {}
} 

Function {} {open
} {
  Fl_Window {} {open
    xywh {331 63 153 73} type Double hide
  } {
    Fl_Output display {
      xywh {11 10 130 20}
    }
    Fl_Button {} {
      label tusar
      callback buttonCB
      xywh {10 40 64 20}
    }
    Fl_Button {} {
      label shiva
      callback buttonCB
      xywh {84 40 64 20}
    }
  }
}

Generated .h file :

CPP / C++ / C Code:

// generated by Fast Light User Interface Designer (fluid) version 1.0300

#ifndef button_test3_h
#define button_test3_h
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Output.H>
extern Fl_Output *display;
#include <FL/Fl_Button.H>
#endif

Generated .cxx file :

CPP / C++ / C Code:

// generated by Fast Light User Interface Designer (fluid) version 1.0300

#include "button_test3.h"

static void buttonCB(Fl_Button*o,void*data) {
  display->value(o->label());
}

Fl_Output *display=(Fl_Output *)0;

int main(int argc, char **argv) {
  Fl_Double_Window* w;
  { Fl_Double_Window* o = new Fl_Double_Window(153, 73);
    w = o;
    { display = new Fl_Output(11, 10, 130, 20);
    } // Fl_Output* display
    { Fl_Button* o = new Fl_Button(10, 40, 64, 20, "tusar");
      o->callback((Fl_Callback*)buttonCB);
    } // Fl_Button* o
    { Fl_Button* o = new Fl_Button(84, 40, 64, 20, "shiva");
      o->callback((Fl_Callback*)buttonCB);
    } // Fl_Button* o
    o->end();
  } // Fl_Double_Window* o
  w->show(argc, argv);
  return Fl::run();
}

I would suggest using FLTK 1.1.8 as it works great. In the future this codebase is going to be migrated to 1.3 which should be,

UTF aware
Doxygen generated docs
using the cleaner 2.0 interface

You should still be able to see what is going on if you look at my fluid file.

Dear cable guy,
I realized it before, that there is no error in coding.I had problem in version and program.
Thanking you for your reply......you are right ......I was trying fltk 1.X program with 2.X version .I thought that was the problem.
My program are
dis.cxx :-

CPP / C++ / C Code:

// generated by Fast Light User Interface Designer (fluid) version 3.1000

#include "dis.h"
#include<fltk/Window.h>
#include<fltk/Button.h>
#include<fltk/Widget.h>
#include</usr/local/include/Fl/Fl_Widget.h>
#include<FL/Fl_Menu_Item.H>

fltk::Input *display=(fltk::Input *)0;

fltk::Button *tusar=(fltk::Button *)0;

fltk::Button *shiva=(fltk::Button *)0;

#include <fltk/run.h>

int main (int argc, char **argv) {

  fltk::Window* w;
   {fltk::Window* o = new fltk::Window(240, 120);
    w = o;
    o->shortcut(0xff1b);
    o->begin();
     {fltk::Input* o = display = new fltk::Input(25, 25, 200, 25, "display");
      //o->show(argc,argv);
    }
     {fltk::Button* o = tusar = new fltk::Button(35, 60, 85, 25, "tusar");
      o->callback((fltk::Callback*)bt_callback, (void*)("tusar"));
    }
     {fltk::Button* o = shiva = new fltk::Button(155, 60, 55, 25, "shiva");
      o->callback((fltk::Callback*)bt_callback, (void*)("shiva"));
    }
    o->end();
    o->resizable(o);
  }
  w->show(argc, argv);
  return  fltk::run();
}

void bt_callback(fltk::Button* m,void* userdata) {
  if(userdata=="tusar")
                        display->text("u pressed tusar");
  else if(userdata=="shiva")
                        display->text("u pressed shiva");
}

dis.h is :-

CPP / C++ / C Code:

// generated by Fast Light User Interface Designer (fluid) version 2.1000

#ifndef dis_h
#define dis_h
#include <fltk/Window.h>
#include <fltk/Input.h>
extern fltk::Input* display;
#include <fltk/Button.h>
extern void bt_callback(fltk::Button*, void*);
extern fltk::Button* tusar;
extern fltk::Button* shiva;
void bt_callback(fltk::Button* m,void* userdata);
#endif

~
and my dis.fl is :-

Code:

# data file for the FLTK User Interface Designer (FLUID)
version 2.1000
images_dir header_name
header_name {.h}
code_name {.cxx}
gridx 5
gridy 5

decl {\#include<fltk/Window.h>} {}

decl {\#include<fltk/Button.h>} {}

decl {\#include<fltk/Widget.h>} {}

decl {\#include</usr/local/include/Fl/Fl_Widget.h>} {}

decl {\#include<FL/Fl_Menu_Item.H>} {}

Function {} {open
} {
  {fltk::Window} {} {open
    xywh {3 19 240 120} hide resizable
  } {
    {fltk::Input} display {
      label display
      xywh {25 25 200 25}
      extra_code {//o->show(argc,argv);}
    }
    {fltk::Button} tusar {
      label tusar
      user_data {"tusar"}
      callback bt_callback
      xywh {35 60 85 25}
    }
    {fltk::Button} shiva {
      label shiva
      user_data {"shiva"}
      callback bt_callback

  }
  }
}

Function {bt_callback(fltk::Button* m,void* userdata)} {open
} {
  code {if(userdata=="tusar")
                        display->text("u pressed tusar");
else if(userdata=="shiva")
                        display->text("u pressed shiva");} {}
}

Again Thanking you for your reply ......Its very tough work to debug others (specially for the person who is beginner)problem

You still are trying to use some 1.1.x stuff. You can just get rid of those lines as you already included the 2.0 versions. In fact, you should be able to get rid of all the decl blocks since the generated .h file takes care of anything you add in fluid.

Thanx
I removed the headers ....It is working perfectly.

Shiva.
Check these out:
ideos here:
http://seriss.com/people/erco/fltk-videos/
It has the compilation, fltk examples + fluid.
There are many source examples here on Erco's Cheat page:
http://seriss.com/people/erco/fltk/
And more in
C:\fltk-1.1.8\documentation
When you manage to compile the projects, you will get executables in:
C:\fltk-1.1.8\test

You should also get the manual at:
http://www.fltk.org/doc-1.1/fltk.pdf
