label : line wrapping

["Jerome COUDERC" <couderj agf fr>]

Hi,

I'm using the function 'gtk_label_set_line_wrap' for a label, which is
placed in a frame, to break lines. But when the frame is resized, the label
keeps always the initial width and doesn't 'reorganize' the text label
(doens't wrap text with new frame size).

How can I correct this?

Thanks in advance,
Jerome
