◆ QQuickMouseArea()

QQuickMouseArea::QQuickMouseArea ( QQuickItem * parent = nullptr )

\qmltype MouseArea \nativetype QQuickMouseArea \inqmlmodule QtQuick

Enables simple mouse handling. \inherits Item

A MouseArea is an invisible item that is typically used in conjunction with a visible item in order to provide mouse handling for that item. By effectively acting as a proxy, the logic for mouse handling can be contained within a MouseArea item.

The \l enabled property is used to enable and disable mouse handling for the proxied item. When disabled, the mouse area becomes transparent to mouse events.

MouseArea is an invisible Item, but it has a visible property. When set to false, the mouse area becomes transparent to mouse events.

The \l pressed read-only property indicates whether or not the user is holding down a mouse button over the mouse area. This property is often used in bindings between properties in a user interface. The containsMouse read-only property indicates the presence of the mouse cursor over the mouse area but, by default, only when a mouse button is held down; see the containsMouse documentation for details.

Information about the mouse position and button clicks are provided via signals for which event handler properties are defined. The most commonly used involved handling mouse presses and clicks: onClicked, onDoubleClicked, onPressed, onReleased and onPressAndHold. It's also possible to handle mouse wheel events via the onWheel signal.

If a MouseArea overlaps with the area of other MouseArea items, you can choose to propagate clicked, doubleClicked and pressAndHold events to these other items by setting propagateComposedEvents to true and rejecting events that should be propagated. See the propagateComposedEvents documentation for details.

By default, MouseArea items only report mouse clicks and not changes to the position of the mouse cursor. Setting the hoverEnabled property ensures that handlers defined for onPositionChanged, onEntered and onExited are used and that the containsMouse property is updated even when no mouse buttons are pressed.

◆ acceptedButtons()

Qt::MouseButtons QQuickMouseArea::acceptedButtons ( ) const

\qmlproperty Qt::MouseButtons QtQuick::MouseArea::acceptedButtons This property holds the mouse buttons that the mouse area reacts to.

To specify that the MouseArea will react to multiple buttons, Qt::MouseButtons flag values are combined using the "|" (or) operator:

MouseArea { acceptedButtons: Qt.LeftButton | Qt.RightButton }

QQuickMouseArea::acceptedButtons

Qt::MouseButtons acceptedButtons

Qt

Definition qcompare.h:72

To indicate that all possible mouse buttons are to be accepted, the special value 'Qt.AllButtons' may be used:

MouseArea { acceptedButtons: Qt.AllButtons }

The default value is Qt.LeftButton.

◆ childMouseEventFilter()

bool QQuickMouseArea::childMouseEventFilter	(	QQuickItem *	item,
		QEvent *	event )

overrideprotectedvirtual

Reimplement this method to filter the pointer events that are received by this item's children.

This method will only be called if filtersChildMouseEvents() is true.

Return true if the specified event should not be passed on to the specified child item, and false otherwise. If you return true, you should also \l {QEvent::accept()}{accept} or \l {QEvent::ignore()}{ignore} the event, to signal if event propagation should stop or continue. The event will, however, always be sent to all childMouseEventFilters up the parent chain.

Note: Despite the name, this function filters all QPointerEvent instances during delivery to all children (typically mouse, touch, and tablet events). When overriding this function in a subclass, we suggest writing generic event-handling code using only the accessors found in QPointerEvent. Alternatively you can switch on event->type() and/or event->device()->type() to handle different event types in different ways.; Filtering is just one way to share responsibility in case of gestural ambiguity (for example on press, you don't know whether the user will tap or drag). Another way is to call QPointerEvent::addPassiveGrabber() on press, so as to non-exclusively monitor the progress of the QEventPoint. In either case, the item or pointer handler that is monitoring can steal the exclusive grab later on, when it becomes clear that the gesture fits the pattern that it is expecting.

◆ containsPress()

bool QQuickMouseArea::containsPress ( ) const

\qmlproperty bool QtQuick::MouseArea::containsPress

Since: 5.4 This is a convenience property equivalent to {pressed && containsMouse}, i.e. it holds whether any of the \l acceptedButtons are currently pressed and the mouse is currently within the MouseArea.

This property is particularly useful for highlighting an item while the mouse is pressed within its bounds.

◆ hovered()

bool QQuickMouseArea::hovered ( ) const

\qmlproperty bool QtQuick::MouseArea::containsMouse This property holds whether the mouse is currently inside the mouse area.

Warning: If hoverEnabled is false, containsMouse will be true when the mouse is pressed while the mouse cursor is inside the MouseArea. But if you set {mouse.accepted = false} in an onPressed handler, containsMouse will remain false because the press was rejected.

◆ hoverEnabled()

bool QQuickMouseArea::hoverEnabled ( ) const

\qmlproperty bool QtQuick::MouseArea::hoverEnabled This property holds whether hover events are handled.

By default, mouse events are only handled in response to a button event, or when a button is pressed. Hover enables handling of all mouse events even when no mouse button is pressed.

This property affects the containsMouse property and the onEntered, onExited and onPositionChanged signals.

bool QQuickMouseArea::isEnabled ( ) const

\qmlproperty bool QtQuick::MouseArea::enabled This property holds whether the item accepts mouse events.

Note: Due to historical reasons, this property is not equivalent to Item.enabled. It only affects mouse events, and its effect does not propagate to child items.

By default, this property is true.

◆ isScrollGestureEnabled()

bool QQuickMouseArea::isScrollGestureEnabled ( ) const

\qmlproperty bool QtQuick::MouseArea::scrollGestureEnabled

Since: 5.5

This property controls whether this MouseArea responds to scroll gestures from non-mouse devices, such as the 2-finger flick gesture on a trackpad. If set to false, the \l wheel signal be emitted only when the wheel event comes from an actual mouse with a wheel, while scroll gesture events will pass through to any other Item that will handle them. For example, the user might perform a flick gesture while the cursor is over an item containing a MouseArea, intending to interact with a Flickable which is underneath. Setting this property to false will allow the PinchArea to handle the mouse wheel or the pinch gesture, while the Flickable handles the flick gesture.

By default, this property is true.

Definition at line 475 of file qquickmousearea.cpp.

◆ mouseX()

qreal QQuickMouseArea::mouseX ( ) const

\qmlproperty real QtQuick::MouseArea::mouseX \qmlproperty real QtQuick::MouseArea::mouseY These properties hold the coordinates of the mouse cursor.

If the hoverEnabled property is false then these properties will only be valid while a button is pressed, and will remain valid as long as the button is held down even if the mouse is moved outside the area.

By default, this property is false.

If hoverEnabled is true then these properties will be valid when: \list

no button is pressed, but the mouse is within the MouseArea (containsMouse is true).
a button is pressed and held, even if it has since moved out of the area. \endlist

int QQuickMouseArea::pressAndHoldInterval ( ) const

\qmlproperty Qt::CursorShape QtQuick::MouseArea::cursorShape This property holds the cursor shape for this mouse area.

Note that on platforms that do not display a mouse cursor this may have no effect.

The available cursor shapes are: \list

In order to only set a mouse cursor shape for a region without reacting to mouse events set the acceptedButtons to none:

MouseArea { cursorShape: Qt.IBeamCursor; acceptedButtons: Qt.NoButton }

The default value is Qt.ArrowCursor.

Note: If the cursorShape property is set to undefined, the MouseArea will not change the existing shape when entering it.

See also: Qt::CursorShape

\qmlproperty int QtQuick::MouseArea::pressAndHoldInterval

Since: 5.9

This property overrides the elapsed time in milliseconds before pressAndHold is emitted.

If not explicitly set – or after reset – the value follows QStyleHints::mousePressAndHoldInterval.

Typically it's sufficient to set this property globally using the application style hint. This property should be used when varying intervals are needed for certain MouseAreas.

\qmlproperty MouseButtons QtQuick::MouseArea::pressedButtons This property holds the mouse buttons currently pressed.

It contains a bitwise combination of: \list

The code below displays "right" when the right mouse buttons is pressed:

        Text {
            text: mouseArea.pressedButtons & Qt.RightButton ? "right" : ""

◆ preventStealing()

bool QQuickMouseArea::preventStealing ( ) const

\qmlproperty bool QtQuick::MouseArea::preventStealing This property holds whether the mouse events may be stolen from this MouseArea.

If a MouseArea is placed within an item that filters child mouse events, such as Flickable, the mouse events may be stolen from the MouseArea if a gesture is recognized by the parent item, e.g. a flick gesture. If preventStealing is set to true, no item will steal the mouse events.

Note that setting preventStealing to true once an item has started stealing events will have no effect until the next press event.

By default this property is false.

◆ preventStealingChanged

◆ propagateComposedEvents()

bool QQuickMouseArea::propagateComposedEvents ( ) const

\qmlproperty bool QtQuick::MouseArea::propagateComposedEvents This property holds whether composed mouse events will automatically propagate to other MouseAreas that overlap with this MouseArea but are lower in the visual stacking order.

By default, this property is false.

MouseArea contains several composed events: clicked, doubleClicked and pressAndHold. These are composed of basic mouse events, like pressed, and can be propagated differently in comparison to basic events.

If propagateComposedEvents is set to true, then composed events will be automatically propagated to other MouseAreas in the same location in the scene. Each event is propagated to the next \l enabled MouseArea beneath it in the stacking order, propagating down this visual hierarchy until a MouseArea accepts the event. Unlike pressed events, composed events will not be automatically accepted if no handler is present.

For example, below is a yellow \l Rectangle that contains a blue \l Rectangle. The blue rectangle is the top-most item in the hierarchy of the visual stacking order; it will visually rendered above the yellow rectangle. Since the blue rectangle sets propagateComposedEvents to true, and also sets \l MouseEvent::accepted to false for all received clicked events, any clicked events it receives are propagated to the MouseArea of the yellow rectangle beneath it.

\qml import QtQuick 2.0

Rectangle { color: "yellow" width: 100; height: 100

MouseArea { anchors.fill: parent onClicked: console.log("clicked yellow") }

Rectangle { color: "blue" width: 50; height: 50

MouseArea { anchors.fill: parent propagateComposedEvents: true onClicked: (mouse)=> { console.log("clicked blue") mouse.accepted = false } } } } \endqml

Clicking on the blue rectangle will cause the onClicked handler of its child MouseArea to be invoked; the event will then be propagated to the MouseArea of the yellow rectangle, causing its own onClicked handler to be invoked.

This property greatly simplifies the usecase of when you want to have overlapping MouseAreas handling the composed events together. For example: if you want one MouseArea to handle clicked signals and the other to handle pressAndHold, or if you want one MouseArea to handle clicked most of the time, but pass it through when certain conditions are met.

drag provides a convenient way to make an item draggable.

\list

drag.target specifies the id of the item to drag.
drag.active specifies if the target item is currently being dragged.
drag.axis specifies whether dragging can be done horizontally (Drag.XAxis), vertically (Drag.YAxis), or both (Drag.XAndYAxis)
drag.minimum and drag.maximum limit how far the target can be dragged along the corresponding axes. \endlist

The following example displays a \l Rectangle that can be dragged along the X-axis. The opacity of the rectangle is reduced when it is dragged to the right.

        Rectangle {
            id: container
            width: 600; height: 200
 
            Rectangle {
                id: rect
                width: 50; height: 50
                color: "red"
                opacity: (600.0 - rect.x) / 600
 
                MouseArea {
                    anchors.fill: parent
                    drag.target: rect
                    drag.axis: Drag.XAxis
                    drag.minimumX: 0
                    drag.maximumX: container.width - rect.width
                }
            }
        }

Note: Items cannot be dragged if they are anchored for the requested drag.axis. For example, if anchors.left or anchors.right was set for rect in the above example, it cannot be dragged along the X-axis. This can be avoided by settng the anchor value to undefined in an \l {pressed}{onPressed} handler.

If drag.filterChildren is set to true, a drag can override descendant MouseAreas. This enables a parent MouseArea to handle drags, for example, while descendants handle clicks:

import QtQuick
 
Rectangle {
    width: 480
    height: 320
    Rectangle {
        x: 30; y: 30
        width: 300; height: 240
        color: "lightsteelblue"
 
        MouseArea {
            anchors.fill: parent
            drag.target: parent;
            drag.axis: "XAxis"
            drag.minimumX: 30
            drag.maximumX: 150
            drag.filterChildren: true
 
            Rectangle {
                color: "yellow"
                x: 50; y : 50
                width: 100; height: 100
                MouseArea {
                    anchors.fill: parent
                    onClicked: console.log("Clicked")
                }
            }
        }
    }
}

drag.threshold determines the threshold in pixels of when the drag operation should start. By default this is bound to a platform dependent value. This property was added in Qt Quick 2.2.

If drag.smoothed is true, the target will be moved only after the drag operation has started. If set to false, the target will be moved straight to the current mouse position. By default, this property is true. This property was added in Qt Quick 2.4

See the \l Drag attached property and \l DropArea if you want to make a drop.
