InvisibleApp.MouseUp event (Visio)

Occurs when a mouse button is released.

Syntax

expression.MouseUp (Button, KeyButtonState, x, y, CancelDefault)

expression A variable that represents an InvisibleApp object.

Parameters

Name	Required/Optional	Data type	Description
Button	Required	Long	The mouse button that was released. Possible values are declared in VisKeyButtonFlags.
KeyButtonState	Required	Long	The state of the mouse buttons and the Shift and Ctrl keys for the event. Possible values can be a combination of the values declared in VisKeyButtonFlags. For example, if KeyButtonState returns 9, it indicates that the user clicked the left mouse button while pressing Ctrl.
x	Required	Double	The x-coordinate of the mouse pointer.
y	Required	Double	The y-coordinate of the mouse pointer.
CancelDefault	Required	Boolean	False if Microsoft Visio should process the message it receives from this event; otherwise, True.

Remarks

If you set CancelDefault to True, Visio will not process the message received when the mouse button is clicked.

Unlike some other Visio events, MouseUp does not have the prefix Query, but it is nevertheless a query event. That is, you can cancel processing the message sent by MouseUp, either by setting CancelDefault to True, or, if you are using the VisEventProc method to handle the event, by returning True. For more information, see the topics for the VisEventProc method and for any of the query events (for example, the QueryCancelSuspend event) in this reference.

If you are using Microsoft Visual Basic or Visual Basic for Applications (VBA), the syntax in this topic describes a common, efficient way to handle events.

If you want to create your own Event objects, use the Add or AddAdvise method.

To create an Event object that runs an add-on, use the Add method as it applies to the EventList collection.

To create an Event object that receives notification, use the AddAdvise method.

To find an event code for the event that you want to create, see Event codes.

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 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) 
 
 If Button = 1 Then 
 
 Debug.Print "Left mouse button clicked" 
 
 ElseIf Button = 2 Then 
 
 Debug.Print "Right mouse button clicked" 
 
 ElseIf Button = 16 Then 
 
 Debug.Print "Center mouse button clicked" 
 
 End If 
 
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 MouseUp event. In the Immediate window, the handler prints the name of the mouse button that was clicked to fire the event.
