POforce FLTK to redraw without event Handles
text
Body
copied!<p>I'm using Fltk to render openGL graphs. currently I'm debugging a global array which is sorted by a heapsort function. My purpose is to see after each swap of elements in the heapsort function a graphical swap of elements. but I don't want to catch an event from FLTK event_handle for every time i need to redraw after I swapped and waiting at breakpoint. (the heapsort function and the opengl render part are running in 2 different threads (if that doesn't has to go without saying)). So the first try I had was to use:</p> <pre><code>Fl::add_timeout(1.0, MyRedrawCallback, (void *)&myWindow); Fl::run(); void MyRedrawCallback(void *myWindow) { MyWindow *pMyWindow; pMyWindow = (MyWindow *) myWindow; pMyWindow->redraw(); Fl::repeat_timeout(1.0, MyRedrawCallback, (void *)&pMyWindow); } </code></pre> <p>But every Time the callback is called the 2nd time i get an "Access violation reading"</p> <p>I'm suggesting that FL::run starts a different thread so maybe the first time is still in same thread so the address of redraw is still usable but after that I'm in a different thread and the function at address is not that what I'm expecting?!</p> <p>But I already took a different way because I wasn't sure i cant even use the timeout on this way. So i was looking for a way to get an event that's eq to "set amount of time passed" or "nothing is happening for..." but there isn't such a handle I'm right?</p> <p>Finally is there a way to let FLTK execute commands even outside the eventloop? or is there another way to solve my problem?</p>
