C++ (Cpp) styleOptionSlider Examples

Example #1

bool ScrollbarThemeQt::paint(Scrollbar* scrollbar, GraphicsContext* graphicsContext, const IntRect& damageRect)
{
    if (graphicsContext->updatingControlTints()) {
       scrollbar->invalidateRect(damageRect);

    if (!p.isValid())

    p.painter->save();

    p.painter->setClipRect(opt->rect.intersected(damageRect));

#ifdef Q_WS_MAC
    p.drawComplexControl(QStyle::CC_ScrollBar, *opt);
#else
    const QPoint topLeft = opt->rect.topLeft();
    p.painter->translate(topLeft);
    opt->rect.moveTo(QPoint(0, 0));

    // The QStyle expects the background to be already filled
    p.painter->fillRect(opt->rect, opt->palette.background());

    p.drawComplexControl(QStyle::CC_ScrollBar, *opt);
    opt->rect.moveTo(topLeft);
#endif
    p.painter->restore();

    return true;
}

Example #2

ScrollbarPart ScrollbarThemeQt::hitTest(Scrollbar* scrollbar, const PlatformMouseEvent& evt)
{
    QStyleOptionSlider* opt = styleOptionSlider(scrollbar);
    const QPoint pos = scrollbar->convertFromContainingWindow(evt.pos());
    opt->rect.moveTo(QPoint(0, 0));
    QStyle::SubControl sc = QApplication::style()->hitTestComplexControl(QStyle::CC_ScrollBar, opt, pos, 0);
    return scrollbarPart(sc);
}

Example #4

int ScrollbarThemeQt::trackLength(Scrollbar* scrollbar)
{

    return scrollbar->orientation() == HorizontalScrollbar ? track.x() - scrollbar->x() : track.y() - scrollbar->y();
}

Example #6

File: ScrollbarThemeQStyle.cpp Project: Moondee/Artemis

{
    QStyleOptionSlider* opt = styleOptionSlider(scrollbar);
    IntRect thumb = style()->subControlRect(QStyle::CC_ScrollBar, opt, QStyle::SC_ScrollBarSlider, 0);
