Example
This class module shows how to define a sink class called MouseListener that listens for events fired by mouse actions in the active window. It declares the object variable vsoWindow by using the WithEvents keyword. The class module also contains event handlers for the MouseDown, MouseMove, and MouseUp events.
To run this example, insert a new class module in your Microsoft Visual Basic for Applications (VBA) project, name it MouseListener, and insert the following code in the module.
Dim WithEvents vsoWindow As Visio.Window
Private Sub Class_Initialize()
Set vsoWindow = ActiveWindow
End Sub
Private Sub Class_Terminate()
Set vsoWindow = Nothing
End Sub
Private Sub vsoWindow_MouseDown(ByVal Button As Long, ByVal KeyButtonState As Long, ByVal x As Double, ByVal y As Double, CancelDefault As Boolean)
Debug.Print "x is: "; x
Debug.Print "y is: "; y
End Sub
Private Sub vsoWindow_MouseMove(ByVal Button As Long, ByVal KeyButtonState As Long, ByVal x As Double, ByVal y As Double, CancelDefault As Boolean)
Debug.Print "x-position is "; x
Debug.Print "y-position is "; y
End Sub
Private Sub vsoWindow_MouseUp(ByVal Button As Long, ByVal KeyButtonState As Long, ByVal x As Double, ByVal y As Double, CancelDefault As Boolean)
If Button = 1 Then
Debug.Print "Left mouse button released"
ElseIf Button = 2 Then
Debug.Print "Right mouse button released"
ElseIf Button = 16 Then
Debug.Print "Center mouse button released"
End If
End Sub
Then, insert the following code in the ThisDocument project.
Dim myMouseListener As MouseListener
Private Sub Document_DocumentSaved(ByVal doc As IVDocument)
Set myMouseListener = New MouseListener
End Sub
Private Sub Document_BeforeDocumentClose(ByVal doc As IVDocument)
Set myMouseListener = Nothing
End Sub
Save the document to initialize the class, and then click anywhere in the active window to fire a MouseDown event. In the Immediate window, the handler prints the x and y coordinates of the location in the Visio window coordinate space where the mouse was clicked.
