Source code¶

#include "painter_layer.h"
#include <QPainter>
#include <QPainterPath>

namespace cf::ui::widget::material::base {

PainterLayer::PainterLayer(QObject* parent)
    : QObject(parent), cached_color_(Qt::black), opacity_(1.0f) {}

void PainterLayer::paint(QPainter* painter, const QPainterPath& clipPath) {
    if (!painter || opacity_ <= 0.0f) {
        return;
    }

    painter->save();
    painter->setClipPath(clipPath);

    // Convert CFColor to QColor and apply opacity
    QColor color = cached_color_.native_color();
    color.setAlphaF(color.alphaF() * opacity_);

    painter->fillPath(clipPath, color);
    painter->restore();
}

} // namespace cf::ui::widget::material::base
