I too have been having problems with 100% widths and unwanted horizontal scrollbar.
I've tried adding minWidth="0" to everything that has a width of 100% but that hasn't fixed the problem that I get an unwanted horizontal scrollbar. I've also tried using the reflex util (http://code.google.com/p/reflexutil/) to change these properties at run time to try and figure out what is causing the problem. What I (basically) have is the following: - (1) Tab navigator - 100% width -- (2) VBox (Tab contents) - 100% width --- (3a) Text --- (3b) HBox - 100% width --- (3c) Tab navigator - 100% width I get the vertical and horizontal scrollbars on the outer tab navigator (1) whenever the content gets taller than the app, in this case I obviously want vertical scrollbars and no horizontal scrollbars. With the reflex util I can change the width of the tab contents children (3a,3b,3c) and I still have horizontal scrollbar. However I cannot change the width of the VBox that wraps the tab contents (2) - it simply keeps resetting to the current value every time I try. I can see that it is the VBox (2) which is overlapping the vertical scrollbar (and thus causing the horizontal scrollbar) using reflex util. So I'm really stumped, I either need a solution to this, or a way to move the scrollbars from the tab navigator (1) to the VBox (2). Any advice would be greatly appreciated. -D
