This property holds whether the popup has active focus.

See also focus and Keyboard Focus in Qt Quick.

This property holds the height available to the contentItem after deducting vertical padding from the height of the popup.

See also padding, topPadding, and bottomPadding.

This property holds the width available to the contentItem after deducting horizontal padding from the width of the popup.

See also padding, leftPadding, and rightPadding.

This property holds the background item.

Note: If the background item has no explicit size specified, it automatically follows the popup's size. In most cases, there is no need to specify width or height for a background item.

Note: Most popups use the implicit size of the background item to calculate the implicit size of the popup itself. If you replace the background item with a custom one, you should also consider providing a sensible implicit size for it (unless it is an item like Image which has its own implicit size).

See also Customizing Popup.

This property holds the bottom margin around the popup.

A popup with a negative bottom margin is not pushed within the bottom edge of the enclosing window. The default value is -1.

See also margins and topMargin.

This property holds the bottom padding.

The padding properties are used to control the geometry of the content item.

Popup uses the same approach to padding as Control. For a visual explanation of the padding system, see the Control Layout section of the documentation.

See also padding, topPadding, and availableHeight.

This property holds whether clipping is enabled. The default value is false.

This property determines the circumstances under which the popup closes. The flags can be combined to allow several ways of closing the popup.

The available values are:

The default value is Popup.CloseOnEscape | Popup.CloseOnPressOutside.

Note: There is a known limitation that the Popup.CloseOnReleaseOutside and Popup.CloseOnReleaseOutsideParent policies only work with modal popups.

This property holds the list of content children.

The list contains all items that have been declared in QML as children of the popup.

Note: Unlike contentData, contentChildren does not include non-visual QML objects.

See also Item::children and contentData.

This property holds the list of content data.

The list contains all objects that have been declared in QML as children of the popup.

Note: Unlike contentChildren, contentData does include non-visual QML objects.

See also Item::data and contentChildren.

This property holds the content height. It is used for calculating the total implicit height of the Popup.

For more information, see Popup Sizing.

See also contentWidth.

This property holds the content item of the popup.

The content item is the visual implementation of the popup. When the popup is made visible, the content item is automatically reparented to the overlay item of its application window.

Note: The content item is automatically resized to fit within the padding of the popup.

Note: Most popups use the implicit size of the content item to calculate the implicit size of the popup itself. If you replace the content item with a custom one, you should also consider providing a sensible implicit size for it (unless it is an item like Text which has its own implicit size).

See also Customizing Popup.

This property holds the content width. It is used for calculating the total implicit width of the Popup.

For more information, see Popup Sizing.

See also contentHeight.

This property holds whether the popup dims the background.

Unless explicitly set, this property follows the value of modal. To return to the default value, set this property to undefined.

See also modal.

This property holds the transition that is applied to the popup item when the popup is opened and enters the screen.

The following example animates the opacity of the popup when it enters the screen:

Popup {
    enter: Transition {
        NumberAnimation { property: "opacity"; from: 0.0; to: 1.0 }
    }
}

See also exit.

This property holds the transition that is applied to the popup item when the popup is closed and exits the screen.

The following example animates the opacity of the popup when it exits the screen:

Popup {
    exit: Transition {
        NumberAnimation { property: "opacity"; from: 1.0; to: 0.0 }
    }
}

See also enter.

This property holds whether the popup wants focus.

When the popup actually receives focus, activeFocus will be true. For more information, see Keyboard Focus in Qt Quick.

The default value is false.

See also activeFocus.

This property holds the font currently set for the popup.

Popup propagates explicit font properties to its children. If you change a specific property on a popup's font, that property propagates to all of the popup's children, overriding any system defaults for that property.

Popup {
    font.family: "Courier"

    Column {
        Label {
            text: qsTr("This will use Courier...")
        }

        Switch {
            text: qsTr("... and so will this")
        }
    }
}

See also Control::font and ApplicationWindow::font.

This property holds the height of the popup.

This property holds the implicit height of the popup.

This property holds the implicit width of the popup.

This property holds the left margin around the popup.

A popup with a negative left margin is not pushed within the left edge of the enclosing window. The default value is -1.

See also margins and rightMargin.

This property holds the left padding.

The padding properties are used to control the geometry of the content item.

Popup uses the same approach to padding as Control. For a visual explanation of the padding system, see the Control Layout section of the documentation.

See also padding, rightPadding, and availableWidth.

This property holds the locale of the popup.

See also LayoutMirroring.

This property holds the default margins around the popup.

A popup with negative margins is not pushed within the bounds of the enclosing window. The default value is -1.

See also topMargin, leftMargin, rightMargin, and bottomMargin.

This property holds whether the popup is modal. The default value is false.

This property holds the opacity of the popup. Opacity is specified as a number between 0.0 (fully transparent) and 1.0 (fully opaque). The default value is 1.0.

This property holds the parent item.

This property holds the right margin around the popup.

A popup with a negative right margin is not pushed within the right edge of the enclosing window. The default value is -1.

See also margins and leftMargin.

This property holds the right padding.

Popup uses the same approach to padding as Control. For a visual explanation of the padding system, see the Control Layout section of the documentation.

See also padding, leftPadding, and availableWidth.

This property holds the scale factor of the popup. The default value is 1.0.

A scale of less than 1.0 causes the popup to be rendered at a smaller size, and a scale greater than 1.0 renders the popup at a larger size. A negative scale causes the popup to be mirrored when rendered.

This property holds the spacing.

Spacing is useful for popups that have multiple or repetitive building blocks. For example, some styles use spacing to determine the distance between the header, content, and footer of Dialog. Spacing is not enforced by Popup, so each style may interpret it differently, and some may ignore it altogether.

This QML property was introduced in QtQuick.Controls 2.1.

This property holds the top margin around the popup.

A popup with a negative top margin is not pushed within the top edge of the enclosing window. The default value is -1.

See also margins and bottomMargin.

This property holds the top padding.

The padding properties are used to control the geometry of the content item.

Popup uses the same approach to padding as Control. For a visual explanation of the padding system, see the Control Layout section of the documentation.

This property holds the origin point for transformations in enter and exit transitions.

Nine transform origins are available, as shown in the image below. The default transform origin is Popup.Center.

See also enter, exit, and Item::transformOrigin.

This property holds whether the popup is visible. The default value is false.

See also open() and close().

This property holds the width of the popup.

This property holds the x-coordinate of the popup.

See also y and z.

This property holds the y-coordinate of the popup.
