Horizontal scrollbar

[grigy]

Hi,

By default the SuperTreeview truncates the text to fit it into the window.
But I want to get the full text shown all the time and add a horizontal scrollbar when the text doesn't fit.
I tried to fix this in the parent container but it seems the SuperTreeview always adapts to the width of the container and truncates the text.
I wonder if there is something that needs to be changed in the SuperTreeview itself.
The CSS is not my strongest area and I'm looking for an advice, what is right way to change this behavior.

Thanks,
Grigor
