I am using fltk-1.3. I guess I don't know the trick you wnat me to do...


Here's my code:


#include<FL/Fl.H>
#include<FL/Fl_Window.H>
#include<Fl/Fl_Button.H>

#include<iostream>
#include<string.h>
using namespace std;

class MainWindow : public Fl_Window
{
    private:
    Fl_Button btnDownload;
    Fl_Button btnAttendence;
    Fl_Button btnMeasurement;
    Fl_Button btnUpload;
    public:
    MainWindow(int width, int height, string appName);
    static void cb_btnDownload    (Fl_Widget *w, void *data);
    static void cb_btnAttendence  (Fl_Widget *w, void *data);
    static void cb_btnMeasurement (Fl_Widget *w, void *data);
    static void cb_btnUpload      (Fl_Widget *w, void *data);
};

MainWindow::MainWindow(int width, int height, string appName):
    Fl_Window(width, height, appName.c_str()),
    btnDownload(40, 40, 170, 30),
    btnAttendence(40, 90, 170, 30),
    btnMeasurement(40, 140, 170, 30),
    btnUpload(40, 190, 170, 30)
{
    color(FL_BLUE);
    begin();
    btnDownload.label("डाउनलोड");
    btnDownload.callback(cb_btnDownload);
    btnAttendence.label("उपस्थिति");
    btnAttendence.callback(cb_btnAttendence);
    btnMeasurement.label("कार्य प्रगति");
    btnMeasurement.callback(cb_btnMeasurement);
    btnUpload.label("अपलोड");
    btnUpload.callback(cb_btnUpload);
    end();
}

void MainWindow::cb_btnDownload(Fl_Widget *w, void *data)
{
    printf("Downloading\n");
}

void MainWindow::cb_btnAttendence(Fl_Widget *w, void *data)
{
    cout<<"Taking attendence.."<<endl;
}

void MainWindow::cb_btnMeasurement(Fl_Widget *w, void *data)
{
    cout<<"Taking Measurements.."<<endl;
}

void MainWindow::cb_btnUpload(Fl_Widget *w, void *data)
{
    cout<<"Uploading.."<<endl;
}

int main(int argc, char **argv)
{
    Fl::visual(FL_DOUBLE|FL_INDEX);
    MainWindow window(240, 270, "emuster");
    window.show();
    return Fl::run();
}
