Do you mean that the application does not scroll? You learn how to make the application scrollable in a later video and exercise. If that's not what you're talking about, can you tell me what you mean by "resizing" in this context? Thanks!
In the example, the woman in the video takes her window and manually resizes it demonstrating how the skin and content panes adjust automatically to the new window size (to a minimum required by the content within the pane).
Let me know if that's still unclear. I'll find some time and reload the project and take a few screenshots.
Thanks for your feedback. Let us test this and get back to you tomorrow.
Sorry for the delayed response.
Are you referring to the part of the video where the browser window is resized so that the application content is not contained within the Rect component? If so, this was only shown in the video to demonstrate how the bottom of the Rect component resizes based on the browser, while the contentGroup does not resize based on browser's height.
In the finished application, you should not see the application's height collapse. However, if you expand your browser, you should see that the Rect component is still constrained to 20 pixels from the bottom of the window.
