We recommend that widgets use color group + roles such as "foreground" and "base" rather than literal colors + like "red" or "turquoise". The color roles are enumerated and + defined in the \l ColorRole documentation. + + The most common use of TQColorGroup is like this: + + \code + TQPainter p; + ... + p.setPen( colorGroup().foreground() ); + p.drawLine( ... ) + \endcode + + It is also possible to modify color groups or create new color + groups from scratch. + + The color group class can be created using three different + constructors or by modifying one supplied by TQt. The default + constructor creates an all-black color group, which can then be + modified using set functions; there's also a constructor for + specifying all the color group colors. And there is also a copy + constructor. + + We strongly recommend using a system-supplied color group and + modifying that as necessary. + + You modify a color group by calling the access functions + setColor() and setBrush(), depending on whether you want a pure + color or a pixmap pattern. + + There are also corresponding color() and brush() getters, and a + commonly used convenience function to get each ColorRole: + background(), foreground(), base(), etc. + + \sa TQColor TQPalette TQWidget::colorGroup() +*/ + + +/*! + \enum TQColorGroup::ColorRole + + The ColorRole enum defines the different symbolic color roles used + in current GUIs. + + The central roles are: + + \value Background general background color. + + \value Foreground general foreground color. + + \value Base used as background color for text entry widgets, for example; + usually white or another light color. + + \value Text the foreground color used with \c Base. Usually this + is the same as the \c Foreground, in which case it must provide good + contrast with \c Background and \c Base. + + \value Button general button background color in which buttons need a + background different from \c Background, as in the Macintosh style. + + \value ButtonText a foreground color used with the \c Button color. + + There are some color roles used mostly for 3D bevel and shadow + effects: + + \value Light lighter than \c Button color. + + \value Midlight between \c Button and \c Light. + + \value Dark darker than \c Button. + + \value Mid between \c Button and \c Dark. + + \value Shadow a very dark color. + By default, the shadow color is \c TQt::black. + + All of these are normally derived from \c Background and used in + ways that depend on that relationship. For example, buttons depend + on it to make the bevels look attractive, and Motif scroll bars + depend on \c Mid to be slightly different from \c Background. + + Selected (marked) items have two roles: + + \value Highlight a color to indicate a selected item or the + current item. By default, the highlight color is \c TQt::darkBlue. + + \value HighlightedText a text color that contrasts with \c Highlight. + By default, the highlighted text color is \c TQt::white. + + Finally, there is a special role for text that needs to be + drawn where \c Text or \c Foreground would give poor contrast, + such as on pressed push buttons: + + \value BrightText a text color that is very different from \c + Foreground and contrasts well with e.g. \c Dark. + + \value Link a text color used for unvisited hyperlinks. + By default, the link color is \c TQt::blue. + + \value LinkVisited a text color used for already visited hyperlinks. + By default, the linkvisited color is \c TQt::magenta. + + \value NColorRoles Internal. + + Note that text colors can be used for things other than just + words; text colors are \e usually used for text, but it's tquite + common to use the text color roles for lines, icons, etc. + + This image shows most of the color roles in use: + \img palette.png Color Roles +*/ + + +class TQColorGroupPrivate : public TQShared +{ +public: + TQBrush br[TQColorGroup::NColorRoles]; + TQColorGroupPrivate* detach() { + if ( count > 1 ) { + deref(); + TQColorGroupPrivate* d = new TQColorGroupPrivate; + for (int i=0; i<TQColorGroup::NColorRoles; i++) + d->br[i] = br[i]; + return d; + } + return this; + } +}; + +/*! + Constructs a color group with all colors set to black. +*/ + +TQColorGroup::TQColorGroup() +{ + static TQColorGroupPrivate* defColorGroupData = 0; + if ( !defColorGroupData ) { + static TQSharedCleanupHandler<TQColorGroupPrivate> defColorGroupCleanup; + defColorGroupData = new TQColorGroupPrivate; + defColorGroupCleanup.set( &defColorGroupData ); + } + d = defColorGroupData; + br = d->br; + d->ref(); +} + +/*! + Constructs a color group that is an independent copy of \a other. +*/ +TQColorGroup::TQColorGroup( const TQColorGroup& other ) +{ + d = other.d; + d->ref(); + br = d->br; +} + +/*! + Copies the colors of \a other to this color group. +*/ +TQColorGroup& TQColorGroup::operator =(const TQColorGroup& other) +{ + if ( d != other.d ) { + if ( d->deref() ) + delete d; + d = other.d; + br = d->br; + d->ref(); + } + return *this; +} + +static TQColor qt_mix_colors( TQColor a, TQColor b) +{ + return TQColor( (a.red() + b.red()) / 2, (a.green() + b.green()) / 2, (a.blue() + b.blue()) / 2 ); +} + + +/*! + Constructs a color group.
