DXmSvnClearSelections - Clears all selections.
The identifier (widget ID) of the SVN widget.
The DXmSvnClearSelections routine clears (cancels) all of the entries in the structure. If no entries are currently selected, the call is ignored. (Use the DXmSvnGetSelections, DXmSvnClearSelections, and DXmSvnShowSelections routines when clearing and showing selections.) Make this call in your application between calls to DXmSvnDisableDisplay and DXmSvnEnableDisplay.
