I've implemented a MXML custom components and I would like to pass parameters to the constructor:
newUser = new userComp("name");
instead of using set methods.
Is this possible if the custom components has been built in MXML (with initialize=myPseudoCostructor() method ?)
Or I can only set the parameter with an additional line of code?
You can't pass variables into an MXML component's constructor. I don't even believe it's possible to define a constructor in an MXML component, though I could be wrong. You can, however, setup properties which have default values, and are changed post-construction.
You could also create an initialization function which is also invoked post-construction.
I've recently run into this problem - what you can do is create an initialisation function which returns the component:
Inside the component (called, for argument's sake, MyComponent):
public function init(...args):MyComponent {
//Add constructor code here
return this;
}
...when creating a component, you can invoke like this:
var myComp:MyComponent = new MyComponent().init(args);
As it returns the object, you can treat it as a constructor. I've had to use this method a lot lately, seems the best method for getting round the problem.
