Can I display ToolTips for my symbols?

Display tooltip for symbols

ToolTips can be displayed using the Model's "NodeMouseEnter" and "NodeMouseLeave" events. Here is a code snippet where ToolTips are displayed only for the Diagram's nodes.

[C#]

private void EventSink_NodeMouseEnter(object sender, NodeMouseEventArgs evtArgs) 
{
    if (evtArgs.Node.GetType() == typeof(MySymbol)) 
    {
        this.toolTip1.SetToolTip(this.diagram1, evtArgs.Node.Name.ToString());
        this.toolTip1.Active = true;
    }
}
private void EventSink_NodeMouseLeave(object sender, NodeMouseEventArgs evtArgs) 
{                                                              
    this.toolTip1.Active = false;                         
}

[VB.NET]

Private Sub EventSink_NodeMouseEnter(ByVal sender As Object, ByVal evtArgs As NodeMouseEventArgs)  
    If evtArgs.Node.Name.StartsWith("MySymbol") Then  
        Me.toolTip1.SetToolTip(Me.diagram1, evtArgs.Node.Name.ToString())  
        Me.toolTip1.Active = True  
    End If 
End Sub
Private Sub EventSink_NodeMouseLeave(ByVal sender As Object, ByVal evtArgs As NodeMouseEventArgs)  
    Me.toolTip1.Active = False 
End Sub
