The MouseMove event is generated continually as the mouse pointer moves across objects. Unless another object has captured the mouse, an object recognizes a MouseMove event whenever the mouse position is within its borders. Use the Background(exCursorHoverColumn) property to specify the visual appearance of the column when the cursor hovers the column. Use the ItemFromPoint property to get the item from cursor. Use the ColumnFromPoint property to get the column from point:

private void MouseMoveEvent(object sender,short Button,short Shift,int X,int Y)
{
}

Private Sub MouseMoveEvent(ByVal sender As System.Object,ByVal Button As Short,ByVal Shift As Short,ByVal X As Integer,ByVal Y As Integer) Handles MouseMoveEvent
End Sub

private void MouseMoveEvent(object sender, AxEXTREELib._ITreeEvents_MouseMoveEvent e)
{
}

void OnMouseMove(short Button,short Shift,long X,long Y)
{
}

void __fastcall MouseMove(TObject *Sender,short Button,short Shift,int X,int Y)

procedure MouseMove(ASender: TObject; Button : Smallint;Shift : Smallint;X : Integer;Y : Integer);

procedure MouseMoveEvent(sender: System.Object; e: AxEXTREELib._ITreeEvents_MouseMoveEvent);

begin event MouseMove(integer Button,integer Shift,long X,long Y)

Private Sub MouseMoveEvent(ByVal sender As System.Object, ByVal e As AxEXTREELib._ITreeEvents_MouseMoveEvent) Handles MouseMoveEvent
End Sub

The following VB sample prints the cell's caption from the cursor ( if the control contains no inner cells. Use the SplitCell property to insert inner cells ) :

Private Sub Tree1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    On Error Resume Next
    ' Converts the container coordinates to client coordinates
    X = X / Screen.TwipsPerPixelX
    Y = Y / Screen.TwipsPerPixelY
    Dim h As HITEM
    Dim c As Long
    Dim hit As EXTREELibCtl.HitTestInfoEnum
    ' Gets the item from (X,Y)
    h = Tree1.ItemFromPoint(X, Y, c, hit)
    If Not (h = 0) Then
        Debug.Print Tree1.Items.CellCaption(h, c) & " HT = " & hit
    End If
End Sub

The following VB sample displays the cell's caption from the cursor ( if the control contains inner cells ):

Private Sub Tree1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)

        Debug.Print Tree1.Items.CellCaption(h, c) & " HT = " & hit
