    \brief Provides tool tips for any control.
 
    A tool tip is a short piece of text that informs the user of a control's
    function. It is typically placed above or below the parent control. The
    tip text can be any \l{Rich Text Processing}{rich text} formatted string.
 
    \image qtquickcontrols-tooltip.png
           {Tooltip displaying helpful text}
 
    \section2 Attached Tool Tips
 
    The most straight-forward way to setup tool tips for controls is to
    specify \l text and \l {visible}{visibility} via attached properties.
    The following example illustrates this approach:
 
    \snippet qtquickcontrols-tooltip.qml 1
 
    Under normal circumstances, there is only one tool tip visible at a time.
    In order to save resources, all items that use the ToolTip attached property
    share the same visual tool tip label instance. Even though the visuals are
    shared, \c text, \c timeout and \c delay are stored individually for each item
    that uses the respective attached property. However, multiple items cannot
    make the shared tool tip visible at the same time. The shared tool tip is only
    shown for the last item that made it visible. The position of the shared tool
    tip is determined by the framework.
 
    \include qquicktooltip.qdocinc customize-note
 
    \section2 Delay and Timeout
 
    Tool tips are typically transient in a sense that they are shown as a
    result of a certain external event or user interaction, and they usually
    hide after a certain timeout. It is possible to control the delay when
    a tool tip is shown, and the timeout when it is hidden. This makes it
    possible to implement varying strategies for showing and hiding tool tips.
 
    For example, on touch screens, it is a common pattern to show a tool tip
    as a result of pressing and holding down a button. The following example
    demonstrates how to delay showing a tool tip until the press-and-hold
    interval is reached. In this example, the tool tip hides as soon as the
    button is released.
 
    \snippet qtquickcontrols-tooltip-pressandhold.qml 1
 
    With pointer devices, however, it might be desired to show a tool tip as
    a result of hovering a button for a while. The following example presents
    how to show a tool tip after hovering a button for a second, and hide it
    after a timeout of five seconds.
 
    \snippet qtquickcontrols-tooltip-hover.qml 1
 
    \section2 Custom Tool Tips
 
    Should one need more fine-grained control over the tool tip position, or
    multiple simultaneous tool tip instances are needed, it is also possible
    to create local tool tip instances. This way, it is possible to
    \l {Customizing ToolTip}{customize} the tool tip, and the whole \l Popup
    API is available. The following example presents a tool tip that presents
    the value of a slider when the handle is dragged.
 
    \image qtquickcontrols-tooltip-slider.png
           {Tooltip attached to slider showing current value}

    This attached property controls whether the visibility of the
    \l {toolTip}{shared tool tip instance} is handled automatically.
    It only has an effect for items on which \c ToolTip.visible \e {has not}
    been set. Only items that set \c ToolTip.text will be made visible. It only
    has an effect for the following items and their derived types: \l Control,
    \l TextArea and \l TextField. All other types require \l visible to be
    manually set.
 
    It also determines the default values for the delay and timeout properties
    of the shared tool tip instance (regardless of whether \c ToolTip.visible
    or \c ToolTip.text have been set).
 
    This property is propagated to attached ToolTip children.
 
    Available values:
    \value ToolTip.Automatic The shared tool tip will be shown when the
        attachee is hovered or long-pressed (if triggered by touch and the
        attachee is an \l AbstractButton or one of its derived types). If
        the visible property has been explicitly set, or the text property has
        not been set, this value has no effect, and the behavior will be
        equivalent to \c ToolTip.Manual.
        The shared tool tip will also default to platform-specific values
        for its delay and timeout properties.
    \value ToolTip.Manual The shared tool tip will not be shown automatically,
        and the developer is responsible for setting the visible property.
        The shared tool tip will not default to platform-specific values
        for its delay and timeout properties.
 
    The default value is \c {ToolTip.Automatic}.
 
    The property provides a way to opt-out of the default values for shared
    tool tips introduced in Qt 6.12. This is particularly relevant for legacy
    code that doesn't explicitly set the visible property before an item is
    interacted with. For applications that declaratively set the visible
    property and find the new default values for delay and timeout acceptable,
    \c policy is not needed.
