Description Juan González 2008-02-11 02:26:49 UTC 
Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc versión 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) 
OS:                Linux

I want to use Plasma::BoxLayout in my applet to show a collection of items, and when clicking on one of them I want to hide the other items and show a different item with information relative to the selected item, but it doesn't remove the items from the layout as I would expect. Maybe I didn't explain it correctly but...

As code is much better than words I've created a little test case that show the bad behavior.
I will attach it to this bug.

you also need to hide/show the items.

side note:

* you don't need contentSizeHint for what you are using it for, just use setMinimumContentSize

* the set up of the GUI should really be done in init(). it's not only better for startup time, it's also likely that eventually you may want configuration values, access to the scene, etc. best to wait until init()

see attached file for a version that works well.
