Please explain me the logic of skins. How to change the skin of entire application? How it interacts with path to icons for each widget and with dhtmlx.image_path ? Should I copy images in one folder or set path for each widget like
mytree.setIconsPath('./codebase/imgs/dhxtree_skyblue/');
mygrid.setIconsPath('./codebase/imgs/dhxgrid_skyblue/');
