[Qt-qml] Applying common behaviour to a group of elements

[alan.westbrook at nokia.com]

So it's a slideshow and each element is a page, and you have hundreds of pages?

Or do you have a few pages each with a bunch of elements?

Or do you have hundreds of elements which pop in and out on a single page?

Depending on what you mean, you could try putting your elements in a model and iterating over them setting opacity. You can also use a Behavior on opacity to enable fade in and out in the element definition.

Or you can fade each page in and out, all child elements will follow the opacity of it's parent page.
