'p,50,0,0,100,100,100' for a triangle) if there are 2 or more regions on one point, the region described in the map with the higher index is used. - getmap (x,y:integer) : integer on which region is the coordinate(x,y) ? result : -1 for no region xx for the index of the map-tstrings - MapCursor,NoMapCursor : tcursor the cursor that will be shown if the mouse is / is not on a region (by default : crHand (included index : 39) / crdefault - createregion (x:integer) : hrgn this function will create a windows-region from map and give back the handle. you have to delete the region after the usage with deleteobject (result) by yourself! overlapping regions will be handled correctly.
