\brief Provides custom styling for Menu.
\target styleData properties
The \b styleData object contains the following read-only properties:
\table
\row \li \b {styleData.index} : int \li The index of the menu item in its menu.
\row \li \b {styleData.type} : enumeration \li The type of menu item. See below for possible values.
\row \li \b {styleData.selected} : bool \li \c true if the menu item is selected.
\row \li \b {styleData.pressed} : bool \li \c true if the menu item is pressed. Available since 5.4.
\row \li \b {styleData.text} : string \li The menu item's text, or title if it's a submenu.
\row \li \b {styleData.underlineMnemonic} : bool \li Whether the style should underline the menu item's label mnemonic.
\row \li \b {styleData.shortcut} : string \li The text for the menu item's shortcut.
\row \li \b {styleData.iconSource} : url \li The source URL to the menu item's icon. Undefined if it has no icon.
\row \li \b {styleData.enabled} : bool \li \c true if the menu item is enabled.
\row \li \b {styleData.checkable} : bool \li \c true if the menu item is checkable.
\row \li \b {styleData.exclusive} : bool \li \c true if the menu item is checkable, and it's part of an \l ExclusiveGroup.
\row \li \b {styleData.checked} : bool \li \c true if the menu item is checkable and currently checked.
\row \li \b {styleData.scrollerDirection} : enumeration \li If the menu item is a scroller, its pointing direction.
Valid values are \c Qt.UpArrow, \c Qt.DownArrow, and \c Qt.NoArrow.
\endtable
The valid values for \b {styleData.type} are:
\list
\li MenuItemType.Item
\li MenuItemType.Menu
\li MenuItemType.Separator
\li MenuItemType.ScrollIndicator
\endlist
\note Styling menus may not be supported on platforms using native menus
through their QPA plugin.

Returns a rich-text string to render mnemonics for a given menu item \a text.
The mnemonic character is prefixed by an ampersand in the original string.
Passing \c true for \a underline will underline the mnemonic character (e.g.,
\c formatMnemonic("&Open...", true) will return \c "<u>O</u>pen..."). Passing \c false
for \a underline will return the plain text form (e.g., \c formatMnemonic("&Open...", false)

/*! \qmlproperty Object MenuStyle::itemDelegate
The object containing the menu item subcontrol components. These subcontrols are used
for normal menu items only, i.e. not for separators or scroll indicators.
The subcontrols are:
\list
\li \b {itemDelegate.background} : Component
The menu item background component.
Its appearance generally changes with \l {styleData properties} {styleData.selected}
and \l {styleData properties} {styleData.enabled}.
The default implementation shows only when the item is enabled and selected. It remains
invisible otherwise.
\li \b {itemDelegate.label} : Component
Component for the actual text label.
The text itself is fetched from \l {styleData properties} {styleData.text}, and its appearance should depend
on \l {styleData properties} {styleData.enabled} and \l {styleData properties} {styleData.selected}.
If \l {styleData properties} {styleData.underlineMnemonic} is true, the label should underline its mnemonic
character. \l formatMnemonic provides the default formatting.
\li \b {itemDelegate.submenuIndicator} : Component
It indicates that the current menu item is a submenu.
Only used when \l {styleData properties} {styleData.type} equals \c MenuItemType.Menu.
\li \b {itemDelegate.shortcut} : Component
Displays the shortcut attached to the menu item.
Only used when \l {styleData properties} {styleData.shortcut} is not empty.
\li \b {itemDelegate.checkmarkIndicator} : Component
Will be used when \l {styleData properties} {styleData.checkable} is \c true and its appearance
may depend on \l {styleData properties} {styleData.exclusive}, i.e., whether it will behave like a
checkbox or a radio button. Use \l {styleData properties} {styleData.checked} for the checked state.
\endlist
\note This property cannot be overwritten although all of the subcontrol properties can.
