// WebMenuRunner ---------------------------------------------------------------
// A class for determining whether an item was selected from an HTML select
// control, or if the menu was dismissed without making a selection. If a menu
// item is selected, MenuDelegate is informed and sets a flag which can be
// queried after the menu has finished running.

@interface WebMenuRunner : NSObject

// Initializes the MenuDelegate with a list of items sent from WebKit.
- (id)initWithItems:(const std::vector<blink::mojom::MenuItemPtr>&)items
           fontSize:(CGFloat)fontSize
       rightAligned:(BOOL)rightAligned;

// Returns YES if an item was selected from the menu, NO if the menu was
// dismissed.
- (BOOL)menuItemWasChosen;

// Displays and runs a native popup menu.
- (void)runMenuInView:(NSView*)view
           withBounds:(NSRect)bounds
         initialIndex:(int)index;

// Cancels the display of a menu if it is shown. This is called in situations
// where Blink is asking for the cancellation (e.g. the page closed or the
// contents of the menu changed so the menu has to be rebuilt). Because this is
// driven by Blink, and in some cases Blink will immediately re-issue the menu,
// this is a synchronous cancellation with no animation. See
// https://crbug.com/812260.
- (void)cancelSynchronously;

// Returns the index of selected menu item, or its initial value (-1) if no item
// was selected.
