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 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
Here is a Sample for displaying ToolTips :
