The main + differences are thinner frames and more modern radio buttons and + checkboxes. Together with a dark background and a bright + text/foreground color, the style looks quite attractive (at least + for Motif fans). + + Note that most of the functions provided by QCDEStyle are + reimplementations of QStyle functions; see QStyle for their + documentation. QCDEStyle provides overloads for drawControl() and + drawPrimitive() which are documented here. + + \img qcdestyle.png + \sa QWindowsXPStyle, QMacStyle, QWindowsStyle, QPlastiqueStyle, QMotifStyle +*/ + +/*! + Constructs a QCDEStyle. + + If \a useHighlightCols is false (the default), then the style will + polish the application's color palette to emulate the Motif way of + highlighting, which is a simple inversion between the base and the + text color. +*/ +QCDEStyle::QCDEStyle(bool useHighlightCols) + : QMotifStyle(useHighlightCols) +{ +} + +/*! + Destroys the style. +*/ +QCDEStyle::~QCDEStyle() +{ +} + + +/*!\reimp +*/ +int QCDEStyle::pixelMetric(PixelMetric metric, const QStyleOption *option, + const QWidget *widget) const +/* +int QCDEStyle::pixelMetric(PixelMetric metric, const QStyleOption *option, + const QWidget *widget) const + */ +{ + int ret = 0; + + switch(metric) { + case PM_MenuBarPanelWidth: + case PM_DefaultFrameWidth: + case PM_FocusFrameVMargin: + case PM_FocusFrameHMargin: + case PM_MenuPanelWidth: + case PM_SpinBoxFrameWidth: + case PM_MenuBarVMargin: + case PM_MenuBarHMargin: + case PM_DockWidgetFrameWidth: + ret = 1; + break; + case PM_ScrollBarExtent: + ret = 13; + break; + default: + ret = QMotifStyle::pixelMetric(metric, option, widget); + break; + } + return ret; +} + +/*! + \reimp +*/ +void QCDEStyle::drawControl(ControlElement element, const QStyleOption *opt, QPainter *p, + const QWidget *widget) const +{ + + switch(element) { + case CE_MenuBarItem: { + if (opt->state & State_Selected) // active item + qDrawShadePanel(p, opt->rect, opt->palette, true, 1, + &opt->palette.brush(QPalette::Button)); + else // other item + p->fillRect(opt->rect, opt->palette.brush(QPalette::Button)); + QCommonStyle::drawControl(element, opt, p, widget); + break; } + case CE_RubberBand: { + p->save(); + p->setClipping(false); + QPainterPath path; + path.addRect(opt->rect); + path.addRect(opt->rect.adjusted(2, 2, -2, -2)); + p->fillPath(path, opt->palette.color(QPalette::Active, QPalette::Text)); + p->restore(); + break; } + default: + QMotifStyle::drawControl(element, opt, p, widget); + break; + } +} + +/*! + \reimp +*/ +void QCDEStyle::drawPrimitive(PrimitiveElement pe, const QStyleOption *opt, QPainter *p, + const QWidget *widget) const +{ + switch(pe) { + case PE_IndicatorCheckBox: { + bool down = opt->state & State_Sunken; + bool on = opt->state & State_On; + bool showUp = !(down ^ on); + QBrush fill = (showUp || (opt->state & State_NoChange)) ?
