well...PLZ help me out. I need a code strip. Because I just started programming with OpenGL and I suck. Well here it is. I want to have and object selected (i.e. a 3d object, 2d object, something with its own properties)then i was a drop menu where I right clicked displaying the strings of info I wanted to. (i.e. right click on a 3d object and it has a drop down menu showing stuff like, position, radius/diamiter ect.) And i was the menus to be costomisable like using an image. So if anyone has the time and is ever so kind..could you help me please.

You need to look up the TrackPopupMenu() function, assuming you're programming in Windows. For a cross-platform solution, I dunno.

For the selection using opengl, the easiest method for this is to use the selection buffer. Here's a small tutorial on how to use it:

For the custom UI part, I would recommend that you start by using the Windows UI. Then if you really need to customize it, you'll either have to create one from scratch, or use an existing one. I believe this library is open source, so you might want to give it a try:

Good Luck !
