[PyQt] Wretched horizontal scrolling of QTreeWidget on Linux

[Vicent Mas]

Hi,

you could catch the itemSelectionChanged() signal, then get the currently 
selected item with selectedItems() and then call scrollToItem() slot. Note 
that you can play with several scroll hint values in the scrollToItem method.
I haven't tested it, sorry.

Hope it helps.
