Pgraphicscontainer.addelement (pelement, 0);

Engine in the Igraphicscontainer similar to the stack, add element, the default is added to the first, so the previously added features will be covered (here, the AddElement function in the ZOrder parameter seems to have no effect), to change the element display order , you can use bringforward,bringtofront,sendtoback,sendbackward these functions to adjust

However, the input parameters of these functions are ienumelement, this seems a little difficult to get, find a half-day finally found a way to get:

Igraphicscontainerselect tmpgselect = (igraphicscontainerselect) mmapcontrol.map;  Tmpgselect.selectelement (pelement);  Pgraphicscontainer.sendtoback (tmpgselect.selectedelements);  Tmpgselect.unselectallelements ();
