Gtk.Widget::get_preferred_height_for_width
function vfunc_get_preferred_height_for_width(width:Number):void { }
Retrieves a widget's minimum and natural height if it would be given the specified width.
The returned request will be modified by the GtkWidgetClass::adjust_size_request virtual method and by any Gtk.SizeGroup<!-- -->s that have been applied. That is, the returned request is the one that should be used for layout, not necessarily the one returned by the widget itself.
