[pygtk] text truncation method

[Ionutz Borcoman]

Hi,

I need to display some text in a given rectangle. If the text is too 
long, the text should be trunctated and '...' appended to what is displayed.

Example: I need to display 'qwertyuiop' but it's too long, so I display 
only 'qwer...'.

In the present I am using something like this:

    def set_layout_label(self, layout, label, max_width):
        layout.set_text(label)
        width, height = layout.get_pixel_size()
        i = -3
        while width > max_width:
            label0 = label[:i] + '...'
            layout.set_text(label0)
            width, height = layout.get_pixel_size()
            i -= 1
        return layout
where layout is a pango layout.

Is there a predefined method/function that does this ? Is there another 
simpler/faster way to set the pango text ?

TIA,

Ionutz
