event DblClick (Shift as Integer, X as OLE_XPOS_PIXELS, Y as OLE_YPOS_PIXELS)

Occurs when the user dblclk the left mouse button over an object.

 TypeDescription 
   Shift as Integer An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys.  
   X as OLE_XPOS_PIXELS A single that specifies the current X location of the mouse pointer. The x values 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 values is always expressed in container coordinates  

The DblClick event is fired when user double clicks the control. Use the ItemFromPoint method to determine the cell over the cursor. Use the ExpandOnDblClk property to specify whether an item is expanded or collapsed when user double clicks it. Use the ColumnFromPoint property to retrieve the column from cursor. Use the DateFromPoint property to specify the date from the cursor. Use the BarFromPoint property to get the bar from the point. Use the LinkFromPoint property to get the link from the point. Almost all properties that get an object from point supports -1,-1 coordinate that specifies the current cursor position, so no conversion is required for X and Y coordinates.

The following Access sample prints a message when an item has been double clicked:

Private Sub G2antt1_DblClick(ByVal Shift As Integer, ByVal X As Long, ByVal Y As Long)
    Dim h As HITEM
    Dim c As Long, hit As Long
    h = G2antt1.ItemFromPoint(-1, -1, c, hit)
    If Not (h = 0) Then
        MsgBox "The """ & G2antt1.Items.CellValue(h, c) & """ cell has been double clicked."
    End If
End Sub

The following VB sample prints a message when an item has been double clicked:

    ' Converts the container coordinates to client coordinates
    X = X / Screen.TwipsPerPixelX
    Y = Y / Screen.TwipsPerPixelY

    ' Gets the item from (X,Y)
    h = G2antt1.ItemFromPoint(X, Y, c, hit)
    If Not (h = 0) Then
        MsgBox "The " & h & " item has been double clicked."
