+  \class QColorDialog qcolordialog.h
+  \brief The QColorDialog class provides a dialog widget for specifying colors.
+  \ingroup dialogs
+
+  The color dialog's function is to allow users to choose colors -
+  for instance, you might use this in a drawing program to allow the
+  user to set the brush color.
+
+  This version of Qt only provides modal color dialogs. The static
+  getColor() function shows the dialog and allows the user to specify a color,
+  while getRgba() does the same but allows the user to specify a color with an
+  alpha channel (transparency) value.
+
+  The user can store customCount() different custom colors. The custom
+  colors are shared by all color dialogs, and remembered during the
+  execution of the program. Use setCustomColor() to set the
+  custom colors, and customColor() to get them.
