Are you trying to update it just once in the main code and never change it? Or are you trying to change it multiple times (as in an animation or moving monkey)?

Setting it once should work fine, but updating it is probably not possible in the main.cpp as things are set up now. The reason is that as soon as a.exec() is called, the “event loop” is passed on to the Qt classes, such as MainWindow which again calls GLWidget. In other words, if you try to do the changes before a.exec() they will be called once, but never again, and if you try to do them after a.exec() they will be called once you quit the application – and that doesn’t really help you out.

The fact is that everything is redrawn within a.exec(), so you can’t animate anything outside the GLWidget (or MainWindow, perhaps). I’m sure some Qt gurus probably can prove me wrong on this, but I wouldn’t start messing around too much with this if you don’t have to.

Setting the initial values for the position should work, so if that is the problem, I’m not sure where it goes wrong. What you do looks perfectly fine in that manner. Are you getting any errors?

The code is great, it works fine for me, but I don’t know enough about Qt + OpenGl to understand the code completely, and I really would like to make a setter for the “monkey” position, I noticed that in the code I can move the “monkey” using “mvMonkey5.translate(player.x(),player.y(),player.z());” in the glwidget.cpp but I would like to modify that parameters in the main code (main.cpp), I tried something like : “mvMonkey5.translate( GLWidget::objetoX, GLWidget::objetoY, GLWidget::objetoZ );” and “void GLWidget::setObjetoZ(int pObjetoZ) {
GLWidget::objetoZ = pObjetoZ;
}”
But it doesn’t work, if you could teach me how to move the “monkey” position and if it’s possible to move the camera position in the main.cpp it would be awesome for me.

Most likely this is caused by a .obj file missing, and if I remember correctly the applications would fail with a segfault if this happens. I don’t think I implemented any file check to see if the file existed and was valid.

I downloaded your QT Obj loader application and run it. But .exe file does not run and programs exits without opening the Output. Is there any updated version of ur application or a working copy? Can you check and upload a working copy.

If that doesn’t work I’ll upload a zip for you and link it. Just give me a notice if that’s the case.

Please can I get a zip file with whole example. If I try to download it from http://github.com/dragly/hellogl_es2_obj_loader then I get html pages.

Thank you,
