[Xerte] icon property

[Julian Tenney]

If you want the actual movieclips to have particular properties, you can
use the initObject property - it uses a shorthand object like this:
{name: "jules", age:"21", likes: "banjos"}

 

Then the movieclip will have properties .name, .age, and .likes

 

Rather than use myIconID.XMLElement.attributes.propertyName, which is a
real mouthful, use myIconID.getProperty('propName'); to return the
values from the attributes of the XLElement.

 

XMLElement was intended as an internal property only.

 

HTH,

Thanks! That helps. XMLElement will be valuable to me the way I am
trying to organize my course (of course I've been programming
exclusively in Authorware for much too long).

When you set the property of an icon using the editor, what you are
doing is setting the value of an attribute in the underlying XML file,
like this:

 

<DIS name="The Name For My Icon" id="myGraphic" x="etc"..../>

 

That xml node is used to initiate a MovieClip at runtime. That movieclip
can be addressed using the id defined in the xml (if it was defined -
otherwise it gets a computer generated name);

 

The values of the attributes in the XML are not necessarily translated
into properties of the resulting movieclip. As you have found, name will
return undefined.

 

Each icon is a movieclip. Each Icon movieclip has a property called
XMLELement. This is the XML node that was used to initiate the icon.

 

So myIcon.XMLElement.attributes.name
<http://myicon.xmlelement.attributes.name/>  will contain the value you
entered in the editor.

 

Hope that helps understand what's going on.

Hi Julian,

 

In the Help file it says:

 

For an icon with an id of 'myIcon', you can address properties and
methods using the following code: 

 

myIcon.property = value;

myIcon.methodName();

 

But myIcon.name does return 'undefined' (for a page).

I get the value of the property 'name' back with myIcon.title...so my
problem is solved, but I do not see why.

Even if I add the property 'title' to the page myIcon.name stays
'undefined', so it is not a mix-up.

Elly
