示例1: colorData
void tst_QMimeData::colorData() const
{
QMimeData mimeData;
QColor red = Qt::red;
QColor blue = Qt::blue;
// set, verify
mimeData.setColorData(red);
QVERIFY(mimeData.hasColor());
QCOMPARE(qvariant_cast<QColor>(mimeData.colorData()), red);
// change, verify
mimeData.setColorData(QColor(Qt::blue));
QVERIFY(mimeData.hasColor());
QCOMPARE(qvariant_cast<QColor>(mimeData.colorData()), blue);
}示例2:
/*
* This function is called when a standalone MimeData instance is passed as parameter to push()
*/
QMimeData *QQuickMimeData::toMimeData()
{
QMimeData *ret = m_mimeData;
if (!m_refData) {
m_mimeData = new QMimeData;
// copy data so we keep the properties as they were
Q_FOREACH(const QString &format, ret->formats()) {
m_mimeData->setData(format, ret->data(format));
}
// set teh color separately
m_mimeData->setColorData(ret->colorData());
}示例3:
QDebug operator<<(QDebug d, const QMimeData &m)
{
QDebug nospace = d.nospace();
const QStringList formats = m.formats();
nospace << "QMimeData: " << formats.join(QStringLiteral(", ")) << '\n'
<< " Text=" << m.hasText() << " HTML=" << m.hasHtml()
<< " Color=" << m.hasColor() << " Image=" << m.hasImage()
<< " URLs=" << m.hasUrls() << '\n';
if (m.hasText())
nospace << " Text: '" << m.text() << "'\n";
if (m.hasHtml())
nospace << " HTML: '" << m.html() << "'\n";
if (m.hasColor())
nospace << " Color: " << qvariant_cast<QColor>(m.colorData()) << '\n';
if (m.hasImage())
nospace << " Image: " << qvariant_cast<QImage>(m.imageData()).size() << '\n';
if (m.hasUrls())
nospace << " URLs: " << m.urls() << '\n';
return d;
