icons and labels in gtk_notebook?

[Jan Struyf <jeans ulyssis org>]

Hi,

I'd like to use a gtk_notebook with an icon and a label as label for each
tab. I have included an example in the code below (still 1.2 code).

The problem is that if I change the text in the label from a long string
to a short string the size of the tab does not change.

E.g.:

+---------------------------+
| [ICON] Long Label For Tab |
+---------------------------+---------------------------+
| ...                                                   |

Becomes (after changing label to "Test"):

+---------------------------+
|       [ICON]         Test |
+---------------------------+---------------------------+
| ...                                                   |

And not:

+-------------+
| [ICON] Test |
+---------------------------+---------------------------+
| ...                                                   |


What am I doing wrong?
The code I've used to test is below.


Best Regards,
