Remarks

A menu draws its entries rather than building a control for each, so without this a menu is an empty node: a screen reader announces "menu" and stops, and an automation client sees a container with nothing in it. That is the one place in a Forma application where the whole command surface can go missing at once.

Properties

Actions

Press and Focus, plus Toggle for a checkable entry.

public override AccessibilityActions Actions { get; }

Property Value

AccessibilityActions

AutomationId

Always empty: an entry is data rather than a control, so it has no automation id.

public override string AutomationId { get; }

Property Value

string

Bounds

The entry's rectangle in global coordinates, matching what pointer input uses.

public override Rectangle Bounds { get; }

Property Value

Rectangle

Children

Always empty. A submenu is a separate menu, reached when it opens.

public override IReadOnlyList<AccessibilityPeer> Children { get; }

Property Value

IReadOnlyList<AccessibilityPeer>

Id

This entry's own identity, distinct from the menu's.

public override int Id { get; }

Property Value

int

Index

Position in the menu's item list, including hidden entries and separators.

public int Index { get; }

Property Value

int

IsVirtual

Always true: an entry is drawn by the menu, not built as a control.

public override bool IsVirtual { get; }

Property Value

bool

Name

The entry's text, which is what an assistive technology announces.

public override string Name { get; }

Property Value

string

Role

Always MenuItem.

public override AccessibilityRole Role { get; }

Property Value

AccessibilityRole

States

Disabled, Checked, Current for the highlighted entry, and Expanded or Collapsed for one that owns a submenu.

public override AccessibilityStates States { get; }

Property Value

AccessibilityStates

Value

Always empty: a menu entry is a command, not a value.

public override string Value { get; }

Property Value

string

Methods

Invoke(AccessibilityActions, object)

Activates this entry rather than the menu. The base implementation forwards to the owning control, which for a menu would mean "press the menu" and do nothing useful.

public override bool Invoke(AccessibilityActions action, object argument = null)

Parameters

action AccessibilityActions

argument object

Returns

bool
