If your X server currently only provides a <tt>GrayScale</tt>, <tt>TrueColor</tt>, <tt>StaticColor</tt> or <tt>StaticGray</tt> visual, you will not be able to allocate colorcells for writing. If this is the case, try setting your X server to 8 bit mode. It should then provide you with at least a <tt>PseudoColor</tt> visual. Note that you may experience colormap flashing if your X server is running in 8 bit mode.</p> <p>Under Windows the size of the colormap is always set to 256 colors. Note that under Windows you can also install colormaps in child widgets.</p> <p>This class uses implicit sharing</tt> as a memory and speed optimization.</p> <p>Example of use:</p> <pre> #include <QApplication> #include <QGLColormap> int main() { QApplication app(argc, argv); MySuperGLWidget widget; <span class="comment">// a QGLWidget in color-index mode</span> QGLColormap colormap; <span
