But if i set wrap-width in some timer callback then text gets wrapped but text column height is not changed. I have attached screenshots for above two cases. case 1: (image 1) wrap-width is set before doing show.Works as expected.text is wrapped and height is adjusted accordingly. case 2: (image 2 and image 3) initially image 2 is displayed as no wrap-width is set but when wrap-width is set say after 5 sec then image 3 is displayed.text gets wrapped but height is not adjusted accordingly and we can't see more than two lines. > > > If there is no pixbuf rendered height never increases beyond one line. > > What does this mean?
