    \brief Base type of popup-like user interface controls.

    Popup is the base type of popup-like user interface controls. It can be
    used with \l Window or \l ApplicationWindow.

    \qml
    import QtQuick.Window
    import QtQuick.Controls

    ApplicationWindow {
        id: window
        width: 400
        height: 400
        visible: true

        Button {
            text: "Open"
            onClicked: popup.open()
        }

        Popup {
            id: popup
            x: 100
            y: 100
            width: 200
            height: 300
            modal: true
            focus: true
            closePolicy: Popup.CloseOnEscape | Popup.CloseOnPressOutsideParent
        }
    }
    \endqml

    Popup does not provide a layout of its own, but requires you to position
    its contents, for instance by creating a \l RowLayout or a \l ColumnLayout.

    Items declared as children of a Popup are automatically parented to the
    Popups's \l contentItem. Items created dynamically need to be explicitly
    parented to the contentItem.

    \section1 Popup Layout

    The following diagram illustrates the layout of a popup within a window:

    \image qtquickcontrols-popup.png

    The \l implicitWidth and \l implicitHeight of a popup are typically based
    on the implicit sizes of the background and the content item plus any insets
    and paddings. These properties determine how large the popup will be when no
    explicit \l width or \l height is specified.

    The geometry of the \l contentItem is determined by the padding. The following
    example reserves 10px padding between the boundaries of the popup and its content:

    \code
    Popup {
        padding: 10

        contentItem: Text {
            text: "Content"
        }
    }
    \endcode

    The \l background item fills the entire width and height of the popup,
    unless insets or an explicit size have been given for it.

    Negative insets can be used to make the background larger than the popup.
    The following example uses negative insets to place a shadow outside the
    popup's boundaries:

    \code
    Popup {
        topInset: -2
        leftInset: -2
        rightInset: -6
        bottomInset: -6

        background: BorderImage {
            source: ":/images/shadowed-background.png"
        }
    }
    \endcode

    \section1 Popup type

    Since Qt 6.8, some popups, such as \l Menu, offer three different implementations,
    depending on the platform. You can choose which one you prefer by setting \l popupType.

    Whether a popup will be able to use the preferred type depends on the platform.
    \c Popup.Item is supported on all platforms, but \c Popup.Window and \c Popup.Native
    are normally only supported on desktop platforms. Additionally, if a popup is a
    \l Menu inside a \l {Native menu bars}{native menubar}, the menu will be native as
    well. And if the menu is a sub-menu inside another menu, the parent (or root) menu
    will decide the type.

    \section2 Showing a popup as an item

    By setting \l popupType to \c Popup.Item, the popup will \e not be shown as a separate
    window, but as an item inside the same scene as the parent. This item is parented
    to that scene's \l{Overlay::overlay}{overlay}, and styled to look like an actual window.

    This option is especially useful on platforms that doesn't support multiple windows.
    This was also the only option before Qt 6.8.

    In order to ensure that a popup is displayed above other items in the
    scene, it is recommended to use ApplicationWindow. ApplicationWindow also
    provides background dimming effects.

    \section2 Showing a popup as a separate window

    By setting \l popupType to \c Popup.Window, the popup will be shown inside a top-level
    \l {QQuickWindow}{window} configured with the \l Qt::Popup flag. Using a window to show a
    popup has the advantage that the popup will float on top of the parent window, and
    can be placed outside of its geometry. The popup will otherwise look the same as when
    using \c Popup.Item, that is, it will use the same QML delegates and styling as
    when using \c Popup.Item.

    \note If the platform doesn't support \c Popup.Window, \c Popup.Item will be used as fallback.

    \section2 Showing a native popup

    By setting \l popupType to \c Popup.Native, the popup will be shown using a platform
    native popup window. This window, and all its contents, will be rendered by the
    platform, and not by QML. This means that the QML delegates assigned to the popup
    will \e not be used for rendering. If you for example
    use this option on a \l Menu, it will be implemented using platform-specific
    menu APIs. This will normally make the popup look and feel more native than for example
    \c Popup.Window, but at the same time, suffer from platform limitations and differences
    related to appearance and behavior. Such limitations are documented in more detail
    in the subclasses that are affected, such as for a
    \l {Limitations when using native menus}{Menu}).

    \note If the platform doesn't support \c Popup.Native, \c Popup.Window will be used as fallback.

    \section1 Popup Sizing

    If only a single item is used within a Popup, it will resize to fit the
    implicit size of its contained item. This makes it particularly suitable
    for use together with layouts.

    \code
    Popup {
        ColumnLayout {
            anchors.fill: parent
            CheckBox { text: qsTr("E-mail") }
            CheckBox { text: qsTr("Calendar") }
            CheckBox { text: qsTr("Contacts") }
        }
    }
    \endcode

    Sometimes there might be two items within the popup:

    \code
    Popup {
        SwipeView {
            // ...
        }
        PageIndicator {
            anchors.horizontalCenter: parent.horizontalCenter
            anchors.bottom: parent.bottom
        }
    }
    \endcode

    In this case, Popup cannot calculate a sensible implicit size. Since we're
    anchoring the \l PageIndicator over the \l SwipeView, we can simply set the
    content size to the view's implicit size:

    \code
    Popup {
        contentWidth: view.implicitWidth
        contentHeight: view.implicitHeight

        SwipeView {
            id: view
            // ...
        }
        PageIndicator {
            anchors.horizontalCenter: parent.horizontalCenter
            anchors.bottom: parent.bottom
        }
     }
    \endcode

    \note When using \l {Showing a popup as an item}{popup items}, the popup's
    \l{contentItem}{content item} gets parented to the \l{Overlay::}{overlay},
    and does not live within the popup's parent. Because of that, a \l{Item::}
    {scale} applied to the tree in which the popup lives does not apply to the
    visual popup. To make the popup of e.g. a \l{ComboBox} follow the scale of
    the combobox, apply the same scale to the \l{Overlay::}{overlay} as well:

    \code
    Window {
        property double scaleFactor: 2.0

        Scale {
            id: scale
            xScale: scaleFactor
            yScale: scaleFactor
        }
        Item {
            id: scaledContent
            transform: scale

            ComboBox {
                id: combobox
                // ...
            }
        }

        Overlay.overlay.transform: scale
    }
    \endcode

    \section1 Popup Positioning

    Similar to items in Qt Quick, Popup's \l x and \l y coordinates are
    relative to its parent. This means that opening a popup that is a
    child of a \l Button, for example, will cause the popup to be positioned
    relative to the button.

    \include qquickoverlay-popup-parent.qdocinc

    Another way to center a popup in the window regardless of its parent item
    is to use \l {anchors.centerIn}:

    \snippet qtquickcontrols-popup.qml centerIn

    To ensure that the popup is positioned within the bounds of the enclosing
    window, the \l margins property can be set to a non-negative value.

    \section1 Showing Non-Child Items in Front of Popup

    In cases where \l {Showing a popup as an item}{popup windows} are not being used,
    Popup sets its contentItem's \l{qtquick-visualcanvas-visualparent.html}{visual parent}
    to be the window's \l{Overlay::overlay}{overlay}, in order to ensure that
    the popup appears in front of everything else in the scene.
    In some cases, it might be useful to put an item in front of a popup,
    such as a \l [QML QtVirtualKeyboard] {InputPanel} {virtual keyboard}.
    This can be done by setting the item's parent to the overlay,
    and giving the item a positive z value. The same result can also be
    achieved by waiting until the popup is opened, before re-parenting the item
    to the overlay.

    \omit
        This shouldn't be a snippet, since we don't want VKB to be a dependency to controls.
    \endomit
    \qml
    Popup {
        id: popup
        visible: true
        anchors.centerIn: parent
        margins: 10
        closePolicy: Popup.CloseOnEscape
        ColumnLayout {
            TextField {
                placeholderText: qsTr("Username")
            }
            TextField {
                placeholderText: qsTr("Password")
                echoMode: TextInput.Password
            }
        }
    }
    InputPanel {
        parent: Overlay.overlay
        width: parent.width
        y: popup.y + popup.topMargin + (window.activeFocusItem?.y ?? 0) + (window.activeFocusItem?.height ?? 0)
        z: 1
    }
    \endqml

    \section1 Popup Transitions

    Since Qt 5.15.3 the following properties are restored to their original values from before
    the enter transition after the exit transition is completed.

    \list
    \li \l opacity
    \li \l scale
    \endlist

    This allows the built-in styles to animate on these properties without losing any explicitly
    defined value.

    \section1 Back/Escape Event Handling

    By default, a Popup will close if:
    \list
    \li It has \l activeFocus,
    \li Its \l closePolicy is \c {Popup.CloseOnEscape}, and
    \li The user presses the key sequence for QKeySequence::Cancel (typically
        the Escape key)
    \endlist

    To prevent this from happening, either:

    \list
    \li Don't give the popup \l focus.
    \li Set the popup's \l closePolicy to a value that does not include
        \c {Popup.CloseOnEscape}.
    \li Handle \l {Keys}' \l {Keys::}{escapePressed} signal in a child item of
        the popup so that it gets the event before the Popup.
    \endlist

    \sa {Popup Controls}, {Customizing Popup}, ApplicationWindow

    \section1 Property Propagation

    Popup inherits fonts, palettes and attached properties through its parent
    window, not its \l {Visual Parent}{object or visual parent}:

    \snippet qtquickcontrols-popup-property-propagation.qml file

    \image qtquickcontrols-basic-popup-property-propagation.png

    In addition, popups do not propagate their properties to child popups. This
    behavior is modelled on Qt Widgets, where a \c Qt::Popup widget is a
    top-level window. Top-level windows do not propagate their properties to
    child windows.

    Certain derived types like ComboBox are typically implemented in such a way
    that the popup is considered an integral part of the control, and as such,
    may inherit things like attached properties. For example, in the
    \l {Material Style}{Material style} ComboBox, the theme and other attached
    properties are explicitly inherited by the Popup from the ComboBox itself:

    \code
    popup: T.Popup {
        // ...

        Material.theme: control.Material.theme
        Material.accent: control.Material.accent
        Material.primary: control.Material.primary
    }
    \endcode

    So, to ensure that a child popup has the same property values as its parent
    popup, explicitly set those properties:

    \code
    Popup {
        id: parentPopup
        // ...

        Popup {
            palette: parentPopup.palette
        }
    }
    \endcode

    \section1 Polish Behavior of Closed Popups

    When a popup is closed, it has no associated window, and neither do its
    child items. This means that any child items will not be
    \l {QQuickItem::polish}{polished} until the popup is shown. For this
    reason, you cannot, for example, rely on a \l ListView within a closed
    \c Popup to update its \c count property:

    \code
    import QtQuick
    import QtQuick.Controls

    ApplicationWindow {
        width: 640
        height: 480
        visible: true

        SomeModel {
            id: someModel
        }

        Button {
            text: view.count
            onClicked: popup.open()
        }

        Popup {
            id: popup
            width: 400
            height: 400
            contentItem: ListView {
                id: view
                model: someModel
                delegate: Label {
                    text: display

                    required property string display
                }
            }
        }
    }
    \endcode

    In the example above, the Button's text will not update when rows are added
    to or removed from \c someModel after \l {Component::completed}{component
    completion} while the popup is closed.

    Instead, a \c count property can be added to \c SomeModel that is updated
    whenever the \l {QAbstractItemModel::}{rowsInserted}, \l
    {QAbstractItemModel::}{rowsRemoved}, and \l
    {QAbstractItemModel::}{modelReset} signals are emitted. The \c Button can
    then bind this property to its \c text.

    \since QtQuick.Controls 2.5 (Qt 5.12)
    \qmlproperty Item QtQuick.Controls::Popup::anchors.centerIn

    Anchors provide a way to position an item by specifying its
    relationship with other items.

    A common use case is to center a popup within its parent. One way to do
    this is with the \l[QtQuick]{Item::}{x} and \l[QtQuick]{Item::}{y} properties. Anchors offer
    a more convenient approach:

    \qml
    Pane {
        // ...

        Popup {
            anchors.centerIn: parent
        }
    }
    \endqml

    It is also possible to center the popup in the window by using \l Overlay:

    \snippet qtquickcontrols-popup.qml centerIn

    This makes it easy to center a popup in the window from any component.

    \note Popups can only be centered within their immediate parent or
    the window overlay; trying to center in other items will produce a warning.

/*!
    \qmlproperty enumeration QtQuick.Controls::Popup::popupType
    \since 6.8

    This property determines the type of popup that is preferred.

    Available options:
    \value Item         The popup will be embedded into the
                        \l{Showing a popup as an item}{same scene as the parent},
                        without the use of a separate window.
    \value Window       The popup will be presented in a \l {Popup type}
                        {separate window}. If the platform doesn't support
                        multiple windows, \c Popup.Item will be used instead.
    \value Native       The popup will be native to the platform. If the
                        platform doesn't support native popups, \c Popup.Window
                        will be used instead.

    Whether a popup will be able to use the preferred type depends on the platform.
    \c Popup.Item is supported on all platforms, but \c Popup.Window and \c Popup.Native
    are normally only supported on desktop platforms. Additionally, if a popup is a
    \l Menu inside a \l {Native menu bars}{native menubar}, the menu will be native as
    well. And if the menu is a sub-menu inside another menu, the parent (or root) menu
    will decide the type.

    The default value is usually \c Popup.Item, with some exceptions, mentioned above.
    This might change in future versions of Qt, for certain styles and platforms that benefit
    from using other popup types.
    If you always want to use native menus for all styles on macOS, for example, you can do:

    \code
    Menu {
        popupType: Qt.platform.os === "osx" ? Popup.Native : Popup.Window
    }
    \endcode

    Also, if you choose to customize a popup (by for example changing any of the
    delegates), you should consider setting the popup type to be \c Popup.Window
    as well. This will ensure that your changes will be visible on all platforms
    and for all styles. Otherwise, when native menus are being used, the delegates
    will \e not be used for rendering.
