IKeyboardInputSink.OnMnemonic Method

Called when one of the mnemonics (access keys) for this sink is invoked.

Namespace:  System.Windows.Interop
Assembly:  WindowsBase (in WindowsBase.dll)

[UIPermissionAttribute(SecurityAction.LinkDemand, Unrestricted = true)]
bool OnMnemonic(
	ref MSG msg,
	ModifierKeys modifiers
)

Parameters

msg
Type: System.Windows.Interop.MSG

The message for the mnemonic and associated data. Do not modify this message structure. It is passed by reference for performance reasons only.

modifiers
Type: System.Windows.Input.ModifierKeys

Modifier keys.

Return Value

Type: System.Boolean
true if the message was handled; otherwise, false.

The Microsoft Windows message must be WM_CHAR, WM_SYSCHAR, WM_DEADCHAR or WM_SYSDEADCHAR. 

If the component has contained components, the message must be passed in your implementation by calling each contained component's OnMnemonic method.

An interface that returns true from TranslateAccelerator will not call OnMnemonic. Implementations can choose to perform all specific key combination handling in TranslateChar.and bypass OnMnemonic.
