At least one - VisualPath is necessary in order to have a PathItem output anything - visible. A VisualPath in turn contains a Path and properties describing the - stroking and filling parameters, such as the stroke width and color, the - fill color or gradient, join and cap styles, and so on. Finally, the Path - object contains a list of path elements like PathMove, PathLine, PathCubic, - PathQuad, PathArc. - - Any property changes in these data sets will be bubble up and change the - output of the PathItem. This means that it is simple and easy to change, or - even animate, the starting and ending position, control points, or any - stroke or fill parameters using the usual QML bindings and animation types - like NumberAnimation. - - In the following example the line join style changes automatically based on - the value of joinStyleIndex: - - \code - VisualPath { - strokeColor: "black" - strokeWidth: 16 - fillColor: "transparent" - capStyle: VisualPath.RoundCap - - property int joinStyleIndex: 0 - property variant styles: [ VisualPath.BevelJoin, VisualPath.MiterJoin, VisualPath.RoundJoin ] - - joinStyle: styles[joinStyleIndex] - - Path { - startX: 30 - startY: 30 - PathLine { x: 100; y: 100 } - PathLine { x: 30; y: 100 } - } - } - \endcode - - Once associated with a PathItem, here is the output with a joinStyleIndex - of 2 (VisualPath.RoundJoin): - - \image visualpath-code-example.png - */ - -QQuickVisualPathPrivate::QQuickVisualPathPrivate() - : path(nullptr), - dirty(DirtyAll) -{ -} - -QQuickVisualPath::QQuickVisualPath(QObject *parent) - : QObject(*(new QQuickVisualPathPrivate), parent) -{ -} - -QQuickVisualPath::~QQuickVisualPath() -{ -} - -/*! - \qmlproperty Path QtQuick::VisualPath::path - - This property holds the Path object. - - \default - */ - -QQuickPath *QQuickVisualPath::path() const -{ - Q_D(const QQuickVisualPath); - return d->path; -} - -void QQuickVisualPath::setPath(QQuickPath *path) -{ - Q_D(QQuickVisualPath); - if (d->path == path) - return; - - if (d->path) - qmlobject_disconnect(d->path, QQuickPath, SIGNAL(changed()), - this, QQuickVisualPath, SLOT(_q_pathChanged())); - d->path = path; - qmlobject_connect(d->path, QQuickPath, SIGNAL(changed()), - this, QQuickVisualPath, SLOT(_q_pathChanged())); - - d->dirty |= QQuickVisualPathPrivate::DirtyPath; - emit pathChanged(); - emit changed(); -} - -void QQuickVisualPathPrivate::_q_pathChanged() -{ - Q_Q(QQuickVisualPath); - dirty |= DirtyPath; - emit q->changed(); -} - -/*! - \qmlproperty color QtQuick::VisualPath::strokeColor - - This property holds the stroking color. - - When set to \c transparent, no stroking occurs. - - The default value is \c white. - */ - -QColor QQuickVisualPath::strokeColor() const -{ - Q_D(const QQuickVisualPath); - return d->sfp.strokeColor; -} - -void QQuickVisualPath::setStrokeColor(const QColor &color) -{ - Q_D(QQuickVisualPath); - if (d->sfp.strokeColor != color) { - d->sfp.strokeColor = color; - d->dirty |= QQuickVisualPathPrivate::DirtyStrokeColor; - emit strokeColorChanged(); - emit changed(); - } -} - -/*! - \qmlproperty color QtQuick::VisualPath::strokeWidth - - This property holds the stroke width. - - When set to a negative value, no stroking occurs. - - The default value is 1. - */ - -qreal QQuickVisualPath::strokeWidth() const -{ - Q_D(const QQuickVisualPath); - return d->sfp.strokeWidth; -} - -void QQuickVisualPath::setStrokeWidth(qreal w) -{ - Q_D(QQuickVisualPath); - if (d->sfp.strokeWidth != w) { - d->sfp.strokeWidth = w; - d->dirty |= QQuickVisualPathPrivate::DirtyStrokeWidth; - emit strokeWidthChanged(); - emit changed(); - } -} - -/*! - \qmlproperty color QtQuick::VisualPath::fillColor - - This property holds the fill color. - - When set to \c transparent, no filling occurs. - - The default value is \c white. - */ - -QColor QQuickVisualPath::fillColor() const -{ - Q_D(const QQuickVisualPath); - return d->sfp.fillColor; -} - -void QQuickVisualPath::setFillColor(const QColor &color) -{ - Q_D(QQuickVisualPath); - if (d->sfp.fillColor != color) { - d->sfp.fillColor = color; - d->dirty |= QQuickVisualPathPrivate::DirtyFillColor; - emit fillColorChanged(); - emit changed(); - } -} - -/*! - \qmlproperty enumeration QtQuick::VisualPath::fillRule - - This property holds the fill rule.

Therefore - PathItem is suitable for creating shapes spreading over larger areas of the - screen, avoiding the performance penalty for texture uploads or framebuffer - blits. In addition, the declarative API allows manipulating, binding to, - and even animating the path element properties like starting and ending - position, the control points, etc. - - The types for specifying path elements are shared between \l PathView and - PathItem. However, not all PathItem implementations support all path - element types, while some may not make sense for PathView. PathItem's - currently supported subset is: PathMove, PathLine, PathQuad, PathCubic, - PathArc, PathSvg. - - See \l Path for a detailed overview of the supported path elements. - - \code - PathItem { - width: 200 - height: 150 - anchors.centerIn: parent - VisualPath { - strokeWidth: 4 - strokeColor: "red" - fillGradient: PathLinearGradient { - x1: 20; y1: 20 - x2: 180; y2: 130 - PathGradientStop { position: 0; color: "blue" } - PathGradientStop { position: 0.2; color: "green" } - PathGradientStop { position: 0.4; color: "red" } - PathGradientStop { position: 0.6; color: "yellow" } - PathGradientStop { position: 1; color: "cyan" } - } - strokeStyle: VisualPath.DashLine - dashPattern: [ 1, 4 ] - Path { - startX: 20; startY: 20 - PathLine { x: 180; y: 130 } - PathLine { x: 20; y: 130 } - PathLine { x: 20; y: 20 } - } - } - } - \endcode - - \image pathitem-code-example.png - - \note It is important to be aware of performance implications, in - particular when the application is running on the generic PathItem - implementation due to not having support for accelerated path rendering. - The geometry generation happens entirely on the CPU in this case, and this - is potentially expensive. Changing the set of path elements, changing the - properties of these elements, or changing certain properties of the - PathItem itself all lead to retriangulation on every change. Therefore, - applying animation to such properties can heavily affect performance on - less powerful systems. If animating properties other than stroke and fill - colors is a must, it is recommended to target systems providing - \c{GL_NV_path_rendering} where the cost of path property changes is much - smaller. - - The following list summarizes the available PathItem rendering approaches: - - \list - - \li When running with the default, OpenGL backend of Qt Quick, both the - generic, triangulation-based and the NVIDIA-specific - \c{GL_NV_path_rendering} methods are available.
