My problem is strange so i write small introduction.
I make it whit this steps.
1 STEP. I Get points who are stored in database (user can add new points
on map who after moderate are showed on map).
2 STEP. I add point to map by use:
$geometryFactory = new MgGeometryFactory();
$coordinate = $geometryFactory->CreateCoordinateXY($x,$y);
$point = $geometryFactory->CreatePoint($coordinate);
...definition of points (symbols,x,y,image of object) are stored in XML
file (who is loaded by
one XML file is generate whit rules of each points who are stored in
3 STEP. I add this points to map (execute my script)
so i get
a) layer is created- and added to layerpane - OK!
b) points are on the map - every have different icon and size.- OK!
BUT when i edit point i change it: (Rotation or X,Y - size in Meters)
THE PROBLEM IS HOW CAN I RELOAD ONLY ONE POINT WHO EDITED WAS?
What i make now;
1. i can delete this point
2. i add new point in this same place - BUT IT have this same definition
of deleted point - so when i add changes (i generate new xml file whit
definition of points) ex. it have another Rotation lebel... the new
points have old gefinition
What can help me:
1. how to delete from curent user session layer whit ceated points - now
i can only hidden only by
2. after dalete it - i must reload in again (whit new XML definition of
each points) - it should by named this same.
