event MouseDown (Button as Integer, Shift as Integer, X as OLE_XPOS_PIXELS, Y as OLE_YPOS_PIXELS)
Occurs when the user presses a mouse button.

TypeDescription
Button as Integer An integer that identifies the button that was pressed to cause the event.
Shift as Integer An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys when the button specified in the button argument is pressed or released.
X as OLE_XPOS_PIXELS A single that specifies the current X location of the mouse pointer. The X value is always expressed in container coordinates.
Y as OLE_YPOS_PIXELS A single that specifies the current Y location of the mouse pointer. The Y value is always expressed in container coordinates.
Use a MouseDown or MouseUp event procedure to specify actions that will occur when a mouse button is pressed or released. Unlike the Click and DblClick events, MouseDown and MouseUp events lets you distinguish between the left, right, and middle mouse buttons. You can also write code for mouse-keyboard combinations that use the SHIFT, CTRL, and ALT keyboard modifiers. Use the GroupFromPoint property to get the group's caption from the point. Use the GroupListFromPoint property to get the group's list from point. Use the ItemFromPoint property to get the item over the cursor. Use the ColumnFromPoint property to get the column's caption over the cursor. The ExpandOnClick property expands the group when its caption is clicked. Use the ShortcutFromPoint property to retrieve the shortcut from the cursor.

The following VB sample prints the cell over the cursor:

Private Sub ExplorerTree1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Dim g As EXPLORERTREELibCtl.Group
    With ExplorerTree1
        Set g = .GroupListFromPoint(X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY)
        If Not (g Is Nothing) Then
            With g
                Dim h As Long, c As Long, hit as Long
                h = .ItemFromPoint(X / Screen.TwipsPerPixelX, Y / Screen.TwipsPerPixelY, c, hit)
                If Not (h = 0) Then
                    With g.Items
                        Debug.Print .CellCaption(h, c)
                    End With
                End If
            End With
        End If
    End With
End Sub

The following VFP sample prints the cell's caption from the cursor:

    If !isnull(g) Then
