(Though I don't think it answers the above question, which was about letting entries get smaller than their normal minimum width, as I undestand it.) > even so, i still have to use set_usize/set_size_request quite often, > particularly to size any kind of textual display widget so that its > wide enough to show the largest string i will ever put there without > resizing dynamically, which looks really, really stupid in my > programs. this also applies to compound widgets like spinbuttons. If you are doing this, you really, really need to check your program with a wide range of font sizes to make sure that it still works. Using set_set_request() occasionally is normal; you shouldn't have to do it *frequently*. And GtkSpinbutton does pick a width based on the range of values you set. Regards, Owen
