\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.

/*!
Constructs a default color dialog. Use setColor() for setting an initial value.
