The example below shows how you can use the MouseRow and MouseCol properties to implement tooltips with text that changes as the mouse moves over the control.
| Example Title |
Copy Code
|
|---|---|
Sub fg_MouseMove(Button As Integer, Shift As Integer, _
X As Single, Y As Single)
Static r As Long, c As Long
Dim nr As Long, nc As Long
' get coordinates
nr = fg.MouseRow
nc = fg.MouseCol
' update tooltip text
If c <> nc Or r <> nr Then
r = nr
c = nc
fg.ToolTipText = "Row:" & r & " Col:" & c
End If
' other processing...
' ...
End Sub

The code keeps track of the last cell for which tooltips were displayed, and refreshes the ToolTipText only when needed. This is done to avoid flicker.
