This function will search widget and all its descendants for a GtkLabel
widget with a text string matching label_pattern.
The label_pattern may contain asterisks “*” and question marks “?” as
placeholders, Pattern.match is used for the matching.
Note that locales other than "C“ tend to alter (translate” label strings,
so this function is genrally only useful in test programs with
predetermined locales, see gtk_test_init() for more details.
