/*!
    \class TQColorDialog ntqcolordialog.h
    \brief The TQColorDialog class provides a dialog widget for specifying colors.
    \mainclass
    \ingroup dialogs
    \ingroup graphics

    The color dialog's function is to allow users to choose colors.
    For example, you might use this in a drawing program to allow the
    user to set the brush color.

    The static functions provide modal color dialogs.
    \omit
    If you require a modeless dialog, use the TQColorDialog constructor.
    \endomit

    The static getColor() function shows the dialog and allows the
    user to specify a color. The getRgba() function does the same but
    also 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 use customColor() to get them.
