+ \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.
+
