\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.
