glutInitDisplayString – Set the window creation display mode. LibraryOpenGLUT – window SynopsisIn openglut.h Ft void Fn glutInitDisplayString const char *displayMode ParametersBf Em displayMode Ef Requested display mode string. DescriptionglutInitDisplayString() permits you to define a display mode for subsequent windows that you open. In most regards, control is at least as fine as with glutInitDisplaymode(). The…

LibraryOpenGLUT – window SynopsisIn openglut.h Ft void Fn glutInitDisplayMode unsigned int displayMode ParametersBf Em displayMode Ef Requested display mode bitmask. DescriptionglutInitDisplayMode() allows you to control the mode for subsequent OpenGLUT windows. Allowable Bf Sy displayMode Ef is a combination of: – Bf Sy GLUT_RGB Ef Red,…
glutInit – Initialize OpenGLUT data structures. LibraryOpenGLUT – mainloop SynopsisIn openglut.h Ft void Fn glutInit int *pargc char **argv ParametersBf Em pargc Ef Pointer to something like main()’s Bf Sy argc. Ef Bf Em argv Ef Something like main()’s Bf Sy argv. Ef DescriptionThis function should be called once, near the start of…
glutIgnoreKeyRepeat – Set autorepeat status. LibraryOpenGLUT – inputstate SynopsisIn openglut.h Ft void Fn glutIgnoreKeyRepeat int ignore ParametersBf Em ignore Ef Whether to ignore autorepeated keys. DescriptionIf Bf Sy ignore Ef is non-zero, then auto-repeat is disabled for keyboard callbacks for the Bf Li current window Ef . See AlsoglutSetKeyRepeat(3)
glutIdleFunc – Sets the global idle callback. LibraryOpenGLUT – idletimer SynopsisIn openglut.h Ft void Fn glutIdleFunc void( *callback )( void ) ParametersBf Em callback Ef Client function for idle event. DescriptionWhen OpenGLUT’s glutMainLoop() is doing nothing else, it checks to see if an “idle” callback set. If so, OpenGLUT invokes that callback. This callback is…
glutIconifyWindow – Iconify the current window LibraryOpenGLUT – window SynopsisIn openglut.h Ft void Fn glutIconifyWindow void DescriptionMost window systems have some kind of “minimized” or “iconified” state for windows. All systems currently supported by OpenGLUT do so. The exact meaning of iconification is somewhat system-dependant, but this makes a request of the window system to…
glutHideWindow – Make the current window hidden LibraryOpenGLUT – window SynopsisIn openglut.h Ft void Fn glutHideWindow void DescriptionEven if a window is “open”, it need not be visible. It may be convenient to hide a window rather than to close it, if you want to re-display the window at the same location and size, later….
