Title: openGL picking inside Gtk widget
Post by: jsmtux on January 22, 2011, 07:51:15 pm

Hi, my name is jsmtux and, although i've been using SFML for quite a long time now, this is my first post in this forum.
I'm having a quite weird problem.
I'm developing a game creator using SFML, with openGL embedded in a Gtk window.
I could pick objects inside the widget, and move them inside it with the mouse. But, yesterday it stopped working. Eventually I tried with a backup which used to work flawlessly and it no longer worked, so I think it might be a libraries-related problem.
Please help me if you have any idea.
Thank you very much.

Did you recently update SFML, Gtk or a driver? Or what have you changed since it worked (configurations or something)?

Which version of ubuntu are you using ?
And what's your graphics card ? your graphics driver ?

Ubuntu 10.10 (maverik), and ati 5600HD with proprietary drivers.
I don't think it is a Gtk issue, as I get the coordinates of the mouse when I click. However, I've written a simple program to test picking with sfml and OpenGL only and it worked flawlessly, so I don't know what to think.

It's ok, don't worry.
I've implemented color picking and it works as needed.
Thanks for your interest!
