AnnIsClipboardDataPresentCallback Delegate

Show in webframe

Callback to determind whether a clipboard paste operation can be performed.

Syntax

AnnIsClipboardDataPresentCallback( 
   automation ,
   format 
)

Parameter	Type	Description
automation	AnnAutomation	Automation object requesting the operation.
format	string	Annotation format. Currently only "AnnObject" is supported.

true if a paste operation can be performed, otherwise; false.

Remarks

This callback is used by AnnAutomation when CanPaste is called. The automation object will query if a callback was set in AnnAutomationManager.PlatformCallbacks and then AnnPlatformCallbacks.IsClipboardDataPresent. The implementer of AnnIsClipboardDataPresentCallback must then call the platform clipboard function to check whether data for format is present.
