Thanks for the reply.
I used Fl_file_chooser differently as I found it one code along with a piece of code for clicking cancel button and it is ok now.
The changed code is:
    Fl_File_Chooser chooser( ".", "Image Files (*.*)", l_File_Chooser::SINGLE,$
    chooser.show();

    // block until user picks something.
    while( chooser.shown() ) { Fl::wait(); }

  // User hit cancel?
    if ( chooser.value() == NULL )
    { fprintf(stderr, "(User hit 'Cancel')\n"); return; }
