Hi everybody,
I'm trying to use fltk within a mex file of matlab. Here you can use
normal c++ in matlab. In stead of of a "int main()" function you of to
define a "void mexFunction(....)". Because of the void, I can't call
"return Fl::run();" at the end. In stead of this I wrote just
"Fl::run(); return;".
The problem with this is, that after returning (to matlab!) my window is
not closed. Does anybody know what could be the problem? How can I
destroy all windows, widgets manually?
My code:
#include <iostream>
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Button.H>
#include <FL/Fl_Input.H>
#include <FL/Fl_Output.H>
#include <math.h>
#include "mex.h"
class SimpleWindow : public Fl_Window{
public:
SimpleWindow(int w, int h, const char* title );
virtual ~SimpleWindow();
Fl_Button* calculate;
Fl_Button* quit;
Fl_Output* result;
private:
static void cb_calculate(Fl_Widget*, void*);
inline void cb_calculate_i();
static void cb_quit(Fl_Widget*, void*);
inline void cb_quit_i();
};
void mexFunction( int nlhs, mxArray *plhs[],
int nrhs, const mxArray *prhs[] ){
SimpleWindow win(300,200,"SimpleWindow");
Fl::run();
return;
}
//----------------------------------------------------
SimpleWindow::SimpleWindow(int w, int h, const char*
title):Fl_Window(w,h,title){
begin();
calculate = new Fl_Button( 10, 150, 70, 30, "C&alculate");
calculate->callback( cb_calculate, this );
quit = new Fl_Button(100, 150, 70, 30, "&Quit");
quit->callback(cb_quit, this);
result = new Fl_Output(50, 100, 140, 30, "Result:");
end();
resizable(this);
show();
}
//----------------------------------------------------
SimpleWindow::~SimpleWindow(){
mexPrintf("SimpleWindow::~SimpleWindow()\n");
// Fl_Window::~Fl_Window();
}
//----------------------------------------------------
void SimpleWindow::cb_calculate(Fl_Widget* o, void* v) {
SimpleWindow* T=(SimpleWindow*)v;
T->cb_calculate_i();
// or just the one line below
//( (SimpleWindow*)v )->cb_copy_i();
}
void SimpleWindow::cb_calculate_i() {
result->value("test");
}
//----------------------------------------------------
void SimpleWindow::cb_quit(Fl_Widget* , void* v) {
( (SimpleWindow*)v )->cb_quit_i();
}
void SimpleWindow::cb_quit_i() {
hide();
}
//----------------------------------------------------
