[Qt-creator] Problems with Dockwidgets

[Ken Ray]

Hey, I'm getting started with QT, so bear with me. I've been trying to work with a Dockwidget that has a treewidget inside of it. 

1) I did a layout vertical layout on the dockWidgetContents and it caused the contained treeview to shrink in size (large borders), is there a way to avoid that behavior ?

2) I changed the size of the dockWidget to a certain width, with policy being preferred, preferred.  This is all done in Creator 1.3.1 .  I then opened a source file and then went bak to the ui view. The dockWidget had reset it's size back to it's original size. There doesn't seem to be anything I can do to keep it from auto resizing itself. Is this a bug ?  Is there a way to fix this problem ?
