Name

XtCreatePopupShell − create a pop-up shell

Syntax

Widget XtCreatePopupShell(name, widget_class, parent, args, num_args)
      String name;
      WidgetClass widget_class;
      Widget parent;
      ArgList args;
      Cardinal num_args;

Arguments

argsSpecifies the argument list to override the resource defaults. 

nameSpecifies the text name for the created shell widget. 

num_argsSpecifies the number of arguments in the argument list. 

parentSpecifies the parent widget. 

widget_classSpecifies the widget class pointer for the created shell widget. 

Description

The XtCreatePopupShell function ensures that the specified class is a subclass of Shell and, rather than using insert_child to attach the widget to the parent’s children list, attaches the shell to the parent’s pop-ups list directly.

A spring-loaded pop-up invoked from a translation table already must exist at the time that the translation is invoked, so the translation manager can find the shell by name.  Pop-ups invoked in other ways can be created “on-the-fly” when the pop-up actually is needed.  This delayed creation of the shell is particularly useful when you pop up an unspecified number of pop-ups.  You can look to see if an appropriate unused shell (that is, not currently popped up) exists and create a new shell if needed.
