Thanks UWE, I tried but no success, still the same. File only accepted when drop over the Fl_Double_Window.
Here is my code.. MainWindow->begin(); // Fl_Double_Window DnDReceiver b(0,0,WINDOW_SIZE_W, WINDOW_SIZE_H); // Drag n Drop Box glutInitDisplayMode (GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_ACCUM | GLUT_ALPHA | GLUT_STENCIL | GLUT_MULTISAMPLE); GLUT_MAIN_WINDOW = glutCreateWindow(RACS_VERSION); MainWindow->end(); MainWindow->show(argc, argv); I tried to put DnDReceiver box before, after, middle, everywhere, inside of begin and end of Fl_Double_Window but no success. Please guide me Where to put "DnDReceiver" box in the code. thanks. > Am 18.02.2013 08:52, schrieb Furqan: > > > Now the issue is, when I drag n drop one file over the OpenGL screen it > > doesn't accept the file.
