HAHA,
Man, it must be Friday.
Ok, the problem is this;
titleIcon is the setter for the reference to the class that is creating the
icon.
You need the actual reference to the icon instance.
try this;
import mx.core.mx_internal;
use namespace mx_internal;
myPanel::mx_internal.titleIconObject.color = 0x00FF00;
BTW we all know mx_internal is not supported but it will get you what you
want. :)
Peace, Mike

Unfortunately that did not work. It looks like the setter is not
really being called after all. When I do this:
myPanel.titleIcon.color = 0x00FF00;
What seems to be happening is that it is creating a property called
"color" just as if myPanel.titleIcon was a generic Object.
I tried creating a "doIconColor" function (rather than using a setter)
in Icon and calling it like this:
Icon(myPanel.titleIcon).doIconColor(0xFF00FF);
But this results in an TypeError:
TypeError: Error #1034: Type Coercion failed: cannot convert
components::Icon$ to components.Icon.
I can't simply do this:
myPanel.titleIcon.doIconColor(0xFF00FF);
because I get a compile error (call to a possibly undefined method
doIconColor)
So the question now becomes, how do I call a function of my Icon
class? Thanks for any suggestions!
