C++ (Cpp) xOffsetChanged Examples

Example #1

File: popupWindow.cpp Project: DynamicPerception/Graffik

void popupWindow::setXOffset(int offset)  {
    if(m_xOffset != offset) {
        m_yOffset = offset;
        updateSize();
        emit xOffsetChanged();
    }
}

Example #2

File: gamelayers.cpp Project: boiko/Quasi-Engine-Test

void GameLayers::setXOffset(const qreal &xOffset)
{
    if (m_xOffset != xOffset) {
        m_xOffset = xOffset;

        emit xOffsetChanged();
    }
}

Example #3

File: shadoweffect.cpp Project: KDE/homerun

void ShadowEffect::setXOffset(qreal value)
{
    if (qFuzzyCompare(m_xOffset, value)) {
        return;
    }
    m_xOffset = value;
    m_shadow = QImage();
    updateBoundingRect();
    xOffsetChanged(m_xOffset);
}

Example #4

File: viewport.cpp Project: diegohcg/Quasi-Engine

void Viewport::setXOffset(float xOffset)
{
    xOffset = xOffset > m_maxXOffset ? m_maxXOffset : xOffset;

    if (xOffset < 0.0f)
        xOffset = 0.0f;

    if (m_xOffset != xOffset) {
        m_xOffset = xOffset;

        if (m_scene)
            m_scene->setX(-m_xOffset);

        emit xOffsetChanged();
    }
}

Example #5

File: gamelayers.cpp Project: boiko/Quasi-Engine-Test

    : GameItem(parent)
    , m_tileWidth(32)
    , m_tileHeight(32)
    , m_totalColumns(0)
    , m_drawType(Quasi::TiledDrawType)
    , m_xOffset(0)
    , m_yOffset(0)
{
    connect(this, SIGNAL(xOffsetChanged()), this, SLOT(changeXOffset()));
    connect(this, SIGNAL(yOffsetChanged()), this, SLOT(changeYOffset()));

    // control variables
    m_drawGrid = false;
    m_gridColor = Qt::red;
}

Example #6
