C++ (Cpp) paintChannel Examples

Example #1

File: DigitalSignalsWidget.cpp Project: ellis/gcead

void DigitalSignalsWidget::paintChannels(QPainter& p, int i0, int i1)
{
	i1 = qMin(i1, m_data.size());

	paintChannel(p, 0x01, 20, QColor(0x00, 0x80, 0x20), i0, i1);
	paintChannel(p, 0x02, 40, Qt::red, i0, i1);
}

Example #2

File: channelitemdelegate.cpp Project: Gira-X/minitube

void ChannelItemDelegate::paint( QPainter* painter,
                                  const QStyleOptionViewItem& option,
                                  const QModelIndex& index ) const {
    const int itemType = index.data(ChannelModel::ItemTypeRole).toInt();
    if (itemType == ChannelModel::ItemChannel)
        paintChannel(painter, option, index);
    else if (itemType == ChannelModel::ItemAggregate)
        paintAggregate(painter, option, index);
    else if (itemType == ChannelModel::ItemUnwatched)
        paintUnwatched(painter, option, index);
    else
        QStyledItemDelegate::paint(painter, option, index);
}

Example #3

File: juce_AudioVisualiserComponent.cpp Project: GMrZhang/JUCE

void AudioVisualiserComponent::paint (Graphics& g)
{
    g.fillAll (backgroundColour);

    Rectangle<float> r (getLocalBounds().toFloat());
    const float channelHeight = r.getHeight() / channels.size();

    g.setColour (waveformColour);

    for (int i = 0; i < channels.size(); ++i)
    {
        const ChannelInfo& c = *channels.getUnchecked(i);

        paintChannel (g, r.removeFromTop (channelHeight),
                      c.levels.begin(), c.levels.size(), c.nextSample);
    }
