Hi
for Tour de Jewel I'm trying to create a component in AS that could be
extended in MXML. The component creates a Tab and two SectionContent.
One is for the current example and the other shows the source code loaded
from GitHub.
So when I add content in mxml to an instance of this component, I don't
want to add to the root of the component. I want to add to one of the tabs.
For this I tried to override addedToParent, but I find that the content is
created in the root and in the tab.
If we see the code:
override public function addedToParent():void
{
if (!_initialized)
{
// each MXML file can also have styles in fx:Style block
ValuesManager.valuesImpl.init(this);
}
super.addedToParent();
if (!_initialized)
{
MXMLDataInterpreter.generateMXMLInstances(_mxmlDocument,
this, MXMLDescriptor);
dispatchEvent(new Event("initBindings"));
dispatchEvent(new Event("initComplete"));
_initialized = true;
//?? why was this added here? childrenAdded(); //?? Is this
needed since MXMLDataInterpreter will already have called it
}
}
I think the problem is in super.addedToParent(); That will create the
content in the root, and we can't change that.
One way to do this is refactor this part :
MXMLDataInterpreter.generateMXMLInstances(_mxmlDocument, this,
MXMLDescriptor);
dispatchEvent(new Event("initBindings"));
dispatchEvent(new Event("initComplete"));
to a function that can be overriden in subclasses, so we can change the
"this" to other component, making it more reusable, .or do other changes
thoughts?
