Hi,
is there a way that the columns of a table are automatically resized
depending on the text that is in it's cells.
At the moment i use the work around to determine the average character
width from a GC and multiply it with the maximum number of characters in
this column, which i think is very messy (especially because it's only the
average character width, so i have to add at least 1 or 2 pixels per
character so that the column is really big enough)
Thanks
Martin

I could be way off, but what the heck! :)
in TreeColumn's Pack routine:
int /*long*/ iter = OS.g_malloc (OS.GtkTreeIter_sizeof ());
if (OS.gtk_tree_model_get_iter_first (parent.modelHandle, iter)) {
do {
width = Math.max (width, parent.calculateWidth (handle, iter));
} while (OS.gtk_tree_model_iter_next(parent.modelHandle, iter));
}
OS.g_free (iter);
seems that it needs to tunnel down through all the children here, as
it's currently just getting the direct children of the parent tree

thanks Veronika, I definitely agree that it doesn't make sense to size
the non-expanded (and thus non-visible) items! :)
any suggestions as to a short term work-around? It doesn't seem that I
can access any size info on a per column per item basis...
