[Gtk-sharp-list] CellRendererCombo / Dropdown-Width

[Elmar Haneke]

Hi,

how can I enforce an CellRendererCombo to draw the dropdown list at an
width sufficient to completely show all items.

Currently I do have the ugly situation that there is an horizontal
scrollbar added which makes the combo unusable. The space effectively
available for listitems is only the colum-with reduced by the width of
the buton to open dropdown even more reduced by the width of the
(required) vertical scrollbar).
