How to put GTK into a C function?

["Mullin Yu" <mullin yu softwareag com>]

Hi all,

 

I saw from the tutorial that we can write a simple GTK application like the following:

 

#include <gtk/gtk.h>

 

int main( int   argc,
          char *argv[] )
{
    GtkWidget *window;
   
    gtk_init (&argc, &argv);
   
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_widget_show  (window);
   
    gtk_main ();
   
    return 0;
}

 

But now, I want to put it inside a function that will call to pop up a window. What should I do? What should I need to pass as argc and argv[]?

 

......

......

 

function test()

{

    // some logic are here

    //

    //

 

    int returnCode;

 

    returnCode = openDialog(NULL, NULL);

 

}

 

 

int openDialog( int   argc,
          char *argv[] )
{
    GtkWidget *window;
   
    gtk_init (&argc, &argv);
   
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_widget_show  (window);
   
    gtk_main ();
   
    return 0;
}

 

Thanks!

 

Best regards,
