ListView resizing, scrollbar

Hi, I am using a listview in view.list. I need to know how I could make the scrolling bar larger in order to have it really usefull on a PDA. Actually, I am trying to make a program that will avoid the use of the stylus. I therefore need to have a scrolling bar larger (my thick fingers cannot grab the scrollbar :-)). Also, I am using the same listview over and over (always in view.list mode), clearing the text that it contains and putting new text. The only problem I am having with that is the size of the column that do not change automatically everytime I have new text. i.e.: I put the text {a, ab, abc}. Then I clear the text. And finally I put {a, b, c}. The columns will still have the width of the first input. Anybody have any idea how I could make the width dynamically resizing everytime I am clearing it and putting new items? I know that I could use something like: myListView.columns[0].width = -1; // -1 standing for the automatic resizing. The problem with this is that I have no column in myListView.columns[] (looked through the debug mode, after having a null reference). It is because I am using myListView.view = view.list and not myListView.view = view.details or something else. If anybody could help, I would really appreciate. Thank you
