Re: [fltk.opengl] Fl_Gl_Window flashes on context creation(Windows7)
You may need to update your libraries or try another compiler, the program runs fine on my Ubuntu64 Linux. Yes it does run fine on my Ubuntu too. The problem are the context creation when running in Windows7. This is using the FLTK 1.3.2 library, compiled with the mingw64 gcc compiler (v.4.7.2 rev9) with the x86_64-w64-mingw32 target. ___ fltk-opengl mailing list fltk-opengl@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-opengl
[fltk.opengl] event_x() To Get FL_Gl_Window Coordinates
I want to be able to left click in an OpenGL window and have the mouse coordinates in that window returned (i.e. relative to the upper left corner of the window). Seems like I should be able to do this using Fl::event_x. However it's turning out to be difficult. First of all the only way I can get event_x to return anything is to put it in the draw function of my Fl_Gl_Window with the syntax Fl::event_x(). But this doesn't return anything when I click in the OpenGL window. It ONLY returns coordinates when I click on a button outside the OGL window. And the X value returned is relative to main FLTK window. Not what I need. Was hoping to be able to put event_x() in the draw function or in the callback to Fl_Gl_Window and get OGL window relative coordinates. The only idea I have now is to put a large button underneath the OGL window. When I click inside the OGL window, this button will be activated and I'll get an x cord. relative to the main FLTK window and have to subtract off the upper left corner coordinates of the OGL window. Anyone have a more elegant solution? ___ fltk-opengl mailing list fltk-opengl@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-opengl

Actually, I've implemented this approach and it seems to be working. ___ fltk-opengl mailing list fltk-opengl@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-opengl
