On GTK+ you can use the function set-interactive-break-gestures both to find and to set the keys that are used interactively as break gestures. When the system detects a break gesture it tries to interrupt any running process, to allow the user to deal with runaway processes.
The element initarg widget-name is used to match resources. CAPI gives a name for the main widget that it creates for each element that has a representation in the library. This name is then included in the "path" that GTK+ uses to match resources for each widget.
By default, the name of the widget is the name of the class of the element, downcased (except top level interfaces, see next paragraph). You can override the name by either passing

To make it easier to define resources specific to the application, the CAPI GTK+ library, when using the default name, prepends the
