I created the following code to create a set of panels to
hold a set of XML topics.
I want to change the size of the panels by a slider, however
I found it is difficult to communicate through the Tilelist.
I think the scope of MyPanel is within the <component>
tag, thus it is not visible outside that tag.
You have code in your changeSize function MyPanel.width =
100;, but I don't think you need it, as you have already set up a
binding to the Panel width with sizeWidth. Actually you are not yet
using the [Bindable] metadata tag. See the attached code, and note
the use of the [Bindable] metadata tag, and the changes to the
<component> tag, particularly the use of the parentDocument
variable to access variables outside the renderer.
