UIManagedTreeListType leans to the left

[gnassas@…]

This comes out of a recent comment made on -users by Steve Adeff:

{{ What I'm talking about is how the two navigation frames work. The left frame, the directory tree, and the right frame the contents tree. If your in the content tree and enter a folder the cursor moves into the directory tree, at the level you were just at! It should stay in the contents tree if your in the contents tree. }}

put another way when you're in a tree view and you go right into a folder you expect the view to shift to the left and the first item inside that folder to be highlighted but that doesn't happen. The shift happens alright but the highlight remains with the folder you just entered. You think you're going to go right but you end up being pulled left. Odd and frustrating. This patch addresses that.

I've been using this for a while and its worked great.

I've been meaning to add a comment for whoever reviews this patch. To see the before/after effect you should create three levels of folders in mythvideo's directory and then, using mythvideo tree view, go into them using the right arrow. Watch where the highlight stays with and without the patch. After I posted the ticket I realized neither Steve's nor my summary mentioned where to see the problem and the code doesn't give much of a hint either.

(In [10046]) Apply patch that changes browse behavior of the 'UIManagedTreeListType' widget slightly. No longer requires two keypresses to move to the right.

Closes #1680.
