Hi there Mind Fusion!

We're using your FlowChartX controls for the front end of our new application, and we wish to add some custom functionality to the FlowChartX.Box class to make it change its Me.Pen color with certain state changes in our app.

I've created a new class inheriting from your FlowChart class and overridden the CreateBox to add my inherited Box class which I've extended with functionality to change its .Pen.Color when the state changes.

However when I execute the CreateBox method, the box isn't shown on the FlowChart. I'm not too sure what to do. Here is my code...

Public Class Chart
    Inherits MindFusion.FlowChartX.FlowChart

    Public Overloads Function CreateBox(ByVal x As Single, _
						    ByVal y As Single, _
						    ByVal width As Single, _
						    ByVal height As Single) As ActionBox
	  Dim newActionBox As ActionBox = New ActionBox(Me)
	  newActionBox.Move(x, y)
	  newActionBox.Resize(width, height)
	  MyBase.Boxes.Add(newActionBox)
	  Return newActionBox
    End Function
End Class

Public Class ActionBox
    Inherits MindFusion.FlowChartX.Box

    Private _action As Action = Nothing

    Public Sub New(ByVal flowChart As MindFusion.FlowChartX.FlowChart)
	  MyBase.New(flowChart)
    End Sub

    Public Property Action() As Action
	  Get
		Return _action
	  End Get
	  Set(ByVal value As Action)
		_action = value
		AddHandler _action.Highlight, AddressOf _action_Highlight
		AddHandler _action.UnHighlight, AddressOf _action_UnHighlight
	  End Set
    End Property

    Private Sub _action_Highlight(ByVal sender As Object, ByVal e As EventArgs)
	  Me.Pen.Color = Drawing.Color.Yellow
    End Sub

    Private Sub _action_UnHighlight(ByVal sender As Object, ByVal e As EventArgs)
	  Me.Pen.Color = Drawing.Color.Black
    End Sub
End Class
 

Can you help?

Cheers,
Chris

That's brilliant!
