Adjusting GtkFileChooserDialog appearance

[Vladislav Grinchenko <vladislav grinchenko comtechmobile com>]

Hi,

I am trying to scale down the width of the GtkFileChooser dialog
to fit in 320x240 display geometry. One annoying thing is that 
the [+ Add][- Remove] buttons of the 'Places' left-side pane define 
its minimal width. 

There is no property to hide it all together (which I would 
like to do very much).

Instead, I thought I can get a hold of the buttons themselves and, 
let's say, take the Labels out and leave icons only. 

Also, It would be totally nice to place 'Places' TreeView into a
GtkScrolledWindow.

But, of course, GtkFileChooser (or its parents) provides no properties
to manipulate all of that.

Perhaps, someone had faced same issues in the past and figured out
how to make the adjustments. 

Thanks in advance for any ideas / code samples.
