event QueryContextToolTip (QContext as String, Keyword as String, ByRef QToolTip as Variant, ByRef QToolTipTitle as Variant)
Asks for the tooltip/title of the keyword on the context retrieved by the QueryContext event.

TypeDescription
QContext as String A String expression defined by the QContext parameter of the QueryContext event
Keyword as String A String expression that defines the keyword at the current position.
QToolTip as Variant (By Reference) A String expression that defines the HTML-tooltip to be displayed. The QToolTip parameter supports built-in HTML tags as shown bellow.
QToolTipTitle as Variant (By Reference) A String expression that defines the title of the tooltip to be displayed.
Use the QueryContextToolTip event to define a new tooltip to be shown for specified context. The QueryContext event queries for the context at the specified location, to provide different tooltips for the same keyword on QueryContextToolTip event. For instance, the QueryContext event occurs when the control is about to find / display the tooltip of the keyword from the cursor.
