[development] how to access Drupal.gmap methods

Hi there, I'm using the drupal gmap module to display some maps and markers. Now I want to extend the functionality with some ajax stuff and I'm having difficulties understanding the javascript Drupal.gmap object. I figured out how to access the google maps object: var m = Drupal.gmap.getMap('yourmapid'); googleobject = m.map Now when looking at the code, I see there are some interesting marker functions defined already in marker.js (and gmap_markers.js). My question is how to access these functions as I always get a not defined error. m.addmarker(...); or m.clearmarkers(); throw above error. Tnx, HnLn
