No code example is currently available or this language may not be supported.

System_CAPS_pubmethodCreateSignatureHelpSession(ITextView, ITrackingPoint, Boolean)

Creates a signature help session without starting it.


Dismisses any active signature help sessions in this broker's ITextView.


Gets the list of all signature help sessions for this broker's ITextView.


Determines whether signature help is active.


Begins the process of signature help at the position of the caret.

System_CAPS_pubmethodTriggerSignatureHelp(ITextView, ITrackingPoint, Boolean)

Starts the process of signature help at the specified point.

The broker is responsible for handling each signature help session from beginning to end. IntelliSense controllers request this broker to trigger or dismiss signature help. The broker can also be used by other components to determine the state of signature help or to trigger the process.

This should be imported as follows:

internal ISignatureHelpBroker m_helpBroker = null;

For an example of the use of this interface, see Walkthrough: Displaying Signature Help.
