_LayoutWidget does not resize in certain contexts

[parente]

The problem is in the startup() method of_LayoutWidget. If the layout widget has a parent, it does not register for resize events from the browser and assumes it will get notified about resizes from its parent container. But consider the nesting:

BorderContainer
- ContentPane (in border container center region)
-- <bunch of stuff>
-- TabContainer
-- <bunch of stuff>

In other words, assume the ContentPane is serving as the container for a whole other set of widgets loaded via href. In this case, the TabContainer sees it has a parent so it does not dojo.connect to onresize. The ContentPane, however, does not think it has a single child, so it doesn't bother to notify the TabContainer when the window resizes.

This was not a problem in Dojo 1.2.x.

Why do you want the TabContainer to know when the window changes size?

In the newest code, ContentPane calls resize() on each of it's children, so the embedded layout widgets are getting resized. See the "embedded layout widgets" tab in test_TabContainer.html, or the more complicated test in ContentPaneLayout.html.

It's true that the TabContainer in your example won't resize when the browser window is resized, but there's no reason to do that.
