Switch delegates are typically used to select one or more - options from a set of options. For smaller sets of options, or for options - that need to be uniquely identifiable, consider using \l Switch instead. - - SwitchDelegate inherits its API from \l ItemDelegate, which is inherited - from \l AbstractButton. For instance, you can set \l {AbstractButton::text}{text}, - and react to \l {AbstractButton::clicked}{clicks} using the \l AbstractButton - API. The state of the switch delegate can be set with the - \l {AbstractButton::}{checked} property. - - \code - ListView { - model: ["Option 1", "Option 2", "Option 3"] - delegate: SwitchDelegate { - text: modelData - } - } - \endcode - - \sa {Customizing SwitchDelegate}, {Delegate Controls} -*/ - -class QQuickSwitchDelegatePrivate : public QQuickItemDelegatePrivate -{ - Q_DECLARE_PUBLIC(QQuickSwitchDelegate) - -public: - qreal positionAt(const QPointF &point) const; - - bool canDrag(const QPointF &movePoint) const; - void handleMove(const QPointF &point, ulong timestamp) override; - void handleRelease(const QPointF &point, ulong timestamp) override; - - QPalette defaultPalette() const override { return QQuickTheme::palette(QQuickTheme::ListView); } - - qreal position = 0; -}; - -qreal QQuickSwitchDelegatePrivate::positionAt(const QPointF &point) const -{ - Q_Q(const QQuickSwitchDelegate); - qreal pos = 0.0; - if (indicator) - pos = indicator->mapFromItem(q, point).x() / indicator->width(); - if (q->isMirrored()) - return 1.0 - pos; - return pos; -} - -bool QQuickSwitchDelegatePrivate::canDrag(const QPointF &movePoint) const -{ - // don't start dragging the handle unless the initial press was at the indicator, - // or the drag has reached the indicator area. this prevents unnatural jumps when - // dragging far outside the indicator. - const qreal pressPos = positionAt(pressPoint); - const qreal movePos = positionAt(movePoint); - return (pressPos >= 0.0 && pressPos <= 1.0) || (movePos >= 0.0 && movePos <= 1.0); -} - -void QQuickSwitchDelegatePrivate::handleMove(const QPointF &point, ulong timestamp) -{ - Q_Q(QQuickSwitchDelegate); - QQuickItemDelegatePrivate::handleMove(point, timestamp); - if (q->keepMouseGrab() || q->keepTouchGrab()) - q->setPosition(positionAt(point)); -} - -void QQuickSwitchDelegatePrivate::handleRelease(const QPointF &point, ulong timestamp) -{ - Q_Q(QQuickSwitchDelegate); - QQuickItemDelegatePrivate::handleRelease(point, timestamp); - q->setKeepMouseGrab(false); - q->setKeepTouchGrab(false); -} - -QQuickSwitchDelegate::QQuickSwitchDelegate(QQuickItem *parent) - : QQuickItemDelegate(*(new QQuickSwitchDelegatePrivate), parent) -{ - Q_D(QQuickSwitchDelegate); - d->keepPressed = true; - setCheckable(true); -} - -/*! - \qmlproperty real QtQuick.Controls::SwitchDelegate::position - \readonly - - \input includes/qquickswitch.qdocinc position -*/ -qreal QQuickSwitchDelegate::position() const -{ - Q_D(const QQuickSwitchDelegate); - return d->position; -} - -void QQuickSwitchDelegate::setPosition(qreal position) -{ - Q_D(QQuickSwitchDelegate); - position = qBound<qreal>(0.0, position, 1.0); - if (qFuzzyCompare(d->position, position)) - return; - - d->position = position; - emit positionChanged(); - emit visualPositionChanged(); -} - -/*! - \qmlproperty real QtQuick.Controls::SwitchDelegate::visualPosition - \readonly - - \input includes/qquickswitch.qdocinc visualPosition -*/ -qreal QQuickSwitchDelegate::visualPosition() const -{ - Q_D(const QQuickSwitchDelegate); - if (isMirrored()) - return 1.0 - d->position; - return d->position; -} - -void QQuickSwitchDelegate::mouseMoveEvent(QMouseEvent *event) -{ - Q_D(QQuickSwitchDelegate); - if (!keepMouseGrab()) { - const QPointF movePoint = event->position(); - if (d->canDrag(movePoint)) - setKeepMouseGrab(QQuickWindowPrivate::dragOverThreshold(movePoint.x() - d->pressPoint.x(), Qt::XAxis, event)); - } - QQuickItemDelegate::mouseMoveEvent(event); -} - -#if QT_CONFIG(quicktemplates2_multitouch) -void QQuickSwitchDelegate::touchEvent(QTouchEvent *event) -{ - Q_D(QQuickSwitchDelegate); - if (!keepTouchGrab() && event->type() == QEvent::TouchUpdate) { - for (const QTouchEvent::TouchPoint &point : event->points()) { - if (point.id() != d->touchId || point.state() != QEventPoint::Updated) - continue; - if (d->canDrag(point.position())) - setKeepTouchGrab(QQuickWindowPrivate::dragOverThreshold(point.position().x() - d->pressPoint.x(), Qt::XAxis, &point)); - } - } - QQuickItemDelegate::touchEvent(event); -} -#endif - -QFont QQuickSwitchDelegate::defaultFont() const -{ - return QQuickTheme::font(QQuickTheme::ListView); -} - -void QQuickSwitchDelegate::mirrorChange() -{ - QQuickItemDelegate::mirrorChange(); - emit visualPositionChanged(); -} - -void QQuickSwitchDelegate::nextCheckState() -{ - Q_D(QQuickSwitchDelegate); - if (keepMouseGrab() || keepTouchGrab()) { - d->toggle(d->position > 0.5); - // the checked state might not change => force a position update to - // avoid that the handle is left somewhere in the middle (QTBUG-57944) - setPosition(d->checked ? 1.0 : 0.0); - } else { - QQuickItemDelegate::nextCheckState(); - } -} - -void QQuickSwitchDelegate::buttonChange(ButtonChange change) -{ - Q_D(QQuickSwitchDelegate); - if (change == ButtonCheckedChange) - setPosition(d->checked ? 1.0 : 0.0); - else - QQuickAbstractButton::buttonChange(change); -} - -QT_END_NAMESPACE |
