NAME

XtCreatePopupChildProc − interface definition for an XtNcreatePopupChildProc
procedure.

SYNOPSIS

typedef void (∗XtCreatePopupChildProc)(Widget);
    Widget shell;

Inputs

shellSpecifies the shell which is being popped up. 

DESCRIPTION

An XtCreatePopupChildProc is registered as the value of the XtNcreatePopupChildProc resource of a shell widget.  It will be called by XtPopup() just before the shell is popped up, and is intended to provide an opportunity for the application to create the popup child of the shell.  See XtPopup(1) and Shell(3) for more information. 

USAGE

None of the standard MIT clients make use of the XtNcreatePopupChildProc resource, and most applications will probably find it simpler to either create both popup shell and popup child in advance, or to delay creation of both until just before XtPopup() is called.  Note that XtPopup() also calls the procedures on a shell’s XtNpopupCallback list, and a callback on this list can be used for the same purpose as an XtNcreatePopupChildProc. 

Note that an XtNcreatePopupChildProc procedure is not a widget class method.  It could be considered an "instance method" rather than a "class method."  In this way it is similar to the XtNinsertPosition procedure of the Composite widget class.
