    \brief A specialized input field designed to use for search functionality.
 
    SearchField is a specialized input field designed to use for search functionality.
    The control includes a text field, search and clear icons, and a popup that
    displays suggestions or search results.

    \section1 SearchField Model Roles
 
    SearchField is able to visualize standard \l {qml-data-models}{data models}
    that provide the \c modelData role:
    \list
    \li models that have only one role
    \li models that do not have named roles (JavaScript array, integer)
    \endlist
 
    When using models that have multiple named roles, SearchField must be configured
    to use a specific \l {textRole}{text role} for its \l {text}{text}
    and \l delegate instances.
 
    \code
    ListModel {
        id : fruitModel
        ListElement { name: "Apple"; color: "green" }
        ListElement { name: "Cherry"; color: "red" }
        ListElement { name: "Banana"; color: "yellow" }
        ListElement { name: "Orange"; color: "orange" }
        ListElement { name: "WaterMelon"; color: "pink" }
    }
 
    SortFilterProxyModel {
        id: fruitFilter
        model: fruitModel
        sorters: [
            RoleSorter {

        ]
        filters: [

/*!
    \qmlsignal void QtQuick.Controls::SearchField::activated(int index)
 
    This signal is emitted when the item at \a index is activated by the user.
 
    An item is activated when it is selected while the popup is open,
    causing the popup to close (and \l currentIndex to change).
    The \l currentIndex property is set to \a index.
 
    \sa currentIndex
*/
 
 
/*!
    \qmlsignal void QtQuick.Controls::SearchField::highlighted(int index)
 
    This signal is emitted when the item at \a index in the popup list is highlighted by the user.
 
    The highlighted signal is only emitted when the popup is open and an item
    is highlighted, but not necessarily \l activated.
 
    \sa highlightedIndex
*/
 
/*!
    \qmlsignal void QtQuick.Controls::SearchField::accepted()
 
    This signal is emitted when the user confirms their input by pressing
    the Enter or Return key.
 
    This signal is typically used to trigger a search or action based on
    the final text input, and it indicates the user's intention to complete
    or submit the query.
 
    \sa searchTriggered()
 */
 
/*!
    \qmlsignal void QtQuick.Controls::SearchField::searchTriggered()
 
    This signal is emitted when a search action is initiated.
 
    It occurs in two cases:
    1. When the Enter or Return key is pressed, it will be emitted together
    with accepted() signal
    2. When the text is edited and if the \l live property is set to \c true,
    this signal will be emitted.
 
    This signal is ideal for initiating searches both on-demand and in real-time as
    the user types, depending on the desired interaction model.
 
    \sa accepted(), textEdited()
 */
 
/*!
    \qmlsignal void QtQuick.Controls::SearchField::textEdited()
 
    This signal is emitted every time the user modifies the text in the
    search field, typically with each keystroke.
