Remarks
This method is responsible for showing the tool tip holding any tool tip information about the identifier at the current location.
The base method calls the GetCaretPos method on the IVsTextView object passed to the ViewFilter constructor to obtain the current caret position. This position is then passed to the OnSyncQuickInfo method on the Source object (obtained from the CodeWindowManager object in the ViewFilter constructor). If OnSyncQuickInfo returns any text, this method next calls the GetFullDataTipText method to get any additional information from the debugger if debugging is active. Finally, a new (or current) TextTipData object is used to display the tool tip.
In the default managed package framework's implementation of the language service classes, this method is called from the HandlePreExec method.
