void Gtk::Widget::set_size_request ( int  width = -1,
int  height = -1 
) [inherited]

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, Gtk::Window::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, Gtk::Window::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 requested.

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 1 by 1, but you can pass 0,0 to this function to mean "as small as possible."

width Width widget should request, or -1 to unset.
height Height widget should request, or -1 to unset.
