Represents a user define function of type
vdSelectionModifiedDelegate that will be called for every user select
Syntax
Example
Example 1:For example we allow user to select all of the entities except lines("vdLine").So every time that copy,rotate,scale,move functions are called,lines can not be selected.
Example 2:For example we allow user to select only one line("vdLine").So every time that copy,rotate,scale,move functions are called,only one line can be selected.

vdcanvas.vdSelectionModified = _vdSelectionModified;//We set the event in the vdrawInitPageLoad()
//Then we create the function which take as parameteres args
function _vdSelectionModified(args) {
//Now we do not allow the user to select lines and we set cancel=true;
if (vdcanvas.Fig_codeToString(args.selectedItem._t) == "vdLine") args.cancel = true;//cancel=true; means that the entity can not be select.
