python - Gtk.CellRendererText makes itself really tall when I wrap it -

i'm trying allow wrapping of text in gtk.cellrenderertext have small problem:

those rows large.

the code changed this:

    cell = gtk.cellrenderertext(markup=0)     cell.set_property("wrap_mode", pango.wrapmode.word)     cell.set_property("wrap_width", 20) 

and makes wrap, seemed make visual issue appear

i seem remember reading on blog @ planet gnome quite while ago. remember there height-for-width drawing model means when wrapping enabled gtklabel etc request enough height reflow text wrap-width if there more horizontal space available leaves loads of empty space when width wider. there fix i'm afraid can't remember @ moment, i'll try , find original post later.

i've tried can't find post, having read more i'm pretty sure problem. there discussion related gtktable doing similar things @ https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/825173 i've nasty feeling fix can't remember might have been turn off wrapping. guess possible notification when column width changes , make wrap-width correct width value that's bit of pain.

if can live column being fixed width, set expand property of column false , fixed-width property true set wrap-width, width-chars , max-width-chars properties of renderer same value text wraps without space.
