If you mean by clicking on the point selecting the point you can use sf.get_ShapeSelected(): http://www.mapwindow.org/documentation/mapwingis4.8/group__shapefile__selection.html#ga491bfd09dea9f90391771971bfab6c7d to get the selected point and read the attribute data and display it.
You can also use the mouse_clickEvent to select shapes around the clickpoint using sf.SelectShapes(): http://www.mapwindow.org/documentation/mapwingis4.8/group__shapefile__selection.html#ga67c36f870d2db98b2c8515f43ef62ac3
