NAMEglutInitDisplayMode — Set the window creation display mode.
LIBRARY
OpenGLUT - window
SYNOPSIS
#include <openglut.h>
void
glutInitDisplayMode(unsigned int displayMode);
PARAMETERS
displayMode Requested display mode bitmask.
DESCRIPTIONglutInitDisplayMode() allows you to control the mode for subsequent
OpenGLUT windows.
Allowable displayMode is a combination of:
- GLUT_RGB
Red, green, blue framebuffer.
- GLUT_RGBA
Red, green, blue, alpha framebuffer.
- GLUT_INDEX
Indexed color framebuffer.
- GLUT_SINGLE
Single-buffered mode.
- GLUT_DOUBLE
Double-buffered mode.
- GLUT_ACCUM
Accumulation buffer.
- GLUT_ALPHA
Alpha channel.
- GLUT_DEPTH
Depth buffering.
- GLUT_STENCIL
Stencil buffering.
- GLUT_MULTISAMPLE
Multisampling mode. (not always available)
- GLUT_STEREO
Left and right framebuffers.
- GLUT_LUMINANCE
Greyscale color mode.
Additionally, the following experimental features are implemented:
- GLUT_OFFSCREEN
Offscreen windows are very much like onscreen windows that have been
dragged off of the edge of the screen. The biggest issue is that off‐
screen windows do not support subwindows. Other than that, onscreen win‐
dows that are dragged off of the edge may not store graphics that you
render (while GLUT_OFFSCREEN windows do), and there is no way to drag
an offscreen window onscreen for user interaction.
- GLUT_BORDERLESS
Borderless windows are very experimental, and their precise behavior is
not set in stone. See also glutCreateMenuWindow().
The following are defaults :
- GLUT_RGB
- GLUT_SINGLE
CAVEATS
Some display mode features were introduced by OpenGLUT.
Not all features or combinations of features are valid for all platforms.
There is no way to change the display mode of an open window.
BUGS
GLUT_OFFSCREEN windows do not work with nVidia cards/drivers. (Both
Win32 and X11)
GLUT_BORDERLESS seems to vary by the window manager on X11, though twm
(for example) performs very similarly to WIN32. But KDE's window manager
(for example) does not let you send keystrokes to borderless windows
without OpenGLUT hacks.
