Hello
Thanks for the tips
I changed it to
int UI::handle(int e) {
and this is my code to create my window with GLUT content and FL content and
start the application:
window = ui->make_window(); //This adds all FL components - built with fluid
window->show();
window->begin();
glutInitWindowSize(635, 745);
glutInitWindowPosition(431, 0);
glutCreateWindow("libjpeg test");
window->end();
glutReshapeFunc(reshape);
glutDisplayFunc(display);
glutIdleFunc(idle);
glutKeyboardFunc(key);
glutKeyboardUpFunc(keyup);
glutMouseFunc(mouse);
glutMotionFunc(mousemove);
glutPassiveMotionFunc(mousemove);
glutSpecialFunc(specialkey);
glutSpecialUpFunc(specialkeyup);
...more GL stuff - enable this, disable that...
Fl::run();
If I put a break point at the very beginning of the handle function, it still
never receives any events. I.e. my break point is never triggered. VC6.0 SP6.
They do reach my glut code, but not the FL handle. Perhaps it's supposed to be
that way?
