Re: [Dynapi-Help] Dynapi3 getContentWidth and Template

[Raymond I. <xw...@ya...>]

Hi,

Let me see if I can explain what's on:


DynAPI.onLoad(init);
function init() {
	var body = 'I am a simply layer, what is my size,
oldWidth is my size before we fill in a template
field, newWidth is the size afterwards. {@field}';
	var sizeTemplate = new Template(body);
	dynapi.document.addChild(sizeTemplate);
	
	// ^ At this point sizeTemplate is created and given
a 
	// width and a height. This is by design. if no
height or width
	// was specified then DynAPI will assign a height and
a width to 
	// the layer once it's created. 
	
	
	sizeTemplate.addChild(new DynLayer('hello'),'field');
	sizeTemplate.generate();

	// ^ At this point the DynLayer is added to the
templated but 
	// due to text wrapping you'll not see the word
"hello"
	// to see the new layer modify your code above to
reflect:
	// var sizeTemplate = new
Template(body,null,null,null,50);
	
The problem you're having is that once the he Template
gets a width assigned to it, it will start text
wrapping. That's why you are not able to see the
'hello' layer or get a different width. The
getContentHeight() function should however reflect a
new height.

Notes. If you call getWidth() on a layer that you did
specify a width for you'll get a 0 or null value.
