Arguments

application_name: Specifies the name of the application instance.
application_class: Specifies the class name of this application.
widget_class: Specifies the widget class that the application top-level widget should be.
display: Specifies the display from which to get the resources.
args: Specifies the argument list in which to set in the WM_COMMAND property.

Description

The XtAppCreateShell function saves the specified application name and application class for qualifying all widget resource specifiers. The application name and application class are used as the left-most components in all widget resource names for this application. XtAppCreateShell should be used to create a new logical application within a program or to create a shell on another display. In the first case, it allows the specification of a new root in the resource hierarchy. In the second case, it uses the resource database associated with the other display.

Note that the widget returned by XtAppCreateShell has the WM_COMMAND and WM_CLASS properties set for window and session managers if the specified widget_class is a subclass of ApplicationsShell (see Chapter 4 of X Toolkit Intrinsics - C Language Interface).
