Ljudi hvala Vam na objasnjenjima. Polako ucim kako se radi. Medjutim, citajuci tutorijal sa sajta (sa onog na kom ima i video zapis), pokusao sam da kompajliram sledeci primer:
Code:
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Button.H>
#include <FL/Fl_Input.H>
#include <FL/Fl_Output.H>
using namespace std;
//---------------------------------------------------
class SimpleWindow : public Fl_Window{
public:
SimpleWindow(int w, int h, const char* title );
~SimpleWindow();
Fl_Button* copy;
Fl_Button* quit;
Fl_Input* inp;
Fl_Output* out;
private:
static void cb_copy(Fl_Widget*, void*);
inline void cb_copy_i();
static void cb_quit(Fl_Widget*, void*);
inline void cb_quit_i();
};
//----------------------------------------------------
int main (){
SimpleWindow win(300,200,"SimpleWindow");
return Fl::run();
}
//----------------------------------------------------
SimpleWindow::SimpleWindow(int w, int h, const char* title):Fl_Window(w,h,title){
begin();
copy = new Fl_Button( 10, 150, 70, 30, "C&opy");
copy->callback( cb_copy, this );
quit = new Fl_Button(100, 150, 70, 30, "&Quit");
quit->callback(cb_quit, this);
inp = new Fl_Input(50, 50, 140, 30, "Input:");
out = new Fl_Output(50, 100, 140, 30, "Output:");
end();
resizable(this);
show();
}
//----------------------------------------------------
SimpleWindow::~SimpleWindow(){}
//----------------------------------------------------
void SimpleWindow::cb_copy(Fl_Widget* o, void* v) {
//SimpleWindow* T=(SimpleWindow*)v;
//T->cb_copy_i();
// or just the one line below
( (SimpleWindow*)v )->cb_copy_i();
}
void SimpleWindow::cb_copy_i() {
out->value(inp->value());
}
//----------------------------------------------------
void SimpleWindow::cb_quit(Fl_Widget* , void* v) {
( (SimpleWindow*)v )->cb_quit_i();
}
void SimpleWindow::cb_quit_i() {
hide();
}
//----------------------------------------------------
Tada dobijam sledecu gresku:
Code:
multiple definition of 'typeinfo for Fl_Widget'
first defined here
.
.
.
I tako za sve headere koje sam ukljucio na pocetku koda.
U cemu je problem?
