i've been getting strange behaviour when connect selection_changed function in filechooserbutton. of so users understand selection_changed syntax. weird happening when use second time in same program. context my aim create window 2 filechooserbuttons , entry text @ end position of window. first filechooserbutton helps user pick directory , causes second filechooserbutton open @ directory user chose in first one. until point code working perfectly. entry drawn , says "here goes filename". intended behaviour change entry's text upon selection of filename in second filechooserbutton after checking whether file writable. the strategy used connect selection_changed function takes care of checking wether file writable , change of entry's text. the problem function never called. added debugging dumb code like: stdout.printf("checking whether function called") it never gets printed,thus suppose function never gets called. function in question fi...
