If you were extending a Container like VBox, its updateDisplayList() implementation would call setActualSize() on the children, taking their percentWidth and percentHeight into account. But when you extend UIComponent, you take on the responsibility for sizing your children.

I've created some custom components by extending UIComponent. I've implemented createChildren, commitProperties, measure, and updateDisplayList. I can resize the custom UIComponents using any number of methods: constraints, CSS, etc. They resize no problem. But if I try to size a child of that custom component, no width or height is assigned, unless I use an explicit setActualSize. For example: My custom component (Content) has been added to a canvas. The component is sized using width and height properties: var content:Content = new Content; content.width = 800; content.height = 800; addChild(content); In content, in createChildren, I create an instance of the Image component. var container:Image = new Image; container.scaleContent = false; addChild(container); I try to do this: container.percentWidth = 100; container.percentHeight = 100; But nothing. I can only seem to resize this inside updateDisplayList like so: container.setActualSize(unscaledWidth, unscaledHeight); Thanks, Brandon
