Method GTK2.Widget()->set_size_request()

Method set_size_request

GTK2.Widget set_size_request(int width, int height)

Description

Sets the minimum size of a widget; that is, the widget's size request will be width by height. You can use this function to force a widget to be either larger or smaller than it normally would be.

In most cases, set_default_size() is a better choice for toplevel windows than this function; setting the default size will still allow users to shrink the window. Setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, set_geometry_hints() can be a useful function as well.

Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct.

The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it request.

If the size request in a given direction is -1 (unset), then the "natural" size request of the widget will be used instead.

Widgets can't actually be allocated a size less than 1x1, but you can pass 0,0 to this function to mean "as small as possible".
