XmPrintSetup: setup and create a Print Shell widget

NAME

SYNOPSIS

#include <Xm/Print.h>
Widget XmPrintSetup(
Widget video_widget,
Screen *print_screen,
String print_shell_name,
ArgList args,
Cardinal num_args);

DESCRIPTION

A function that does the appropriate setting and creates a realized XmPrintShell that it returns to the caller. This function hides the details of the Xt to set up a valid print shell heirarchy for the application. It is also meant to encourage consistency in the way applications root their print widget hierarchy.

print_screen must belong to a Display connection that has already been initialized with Xt.

The video_widget is used to get at the application context, application name and class, and argc/argv stored on the applicationShell that roots this widget. If no applicationShell is found, NULL argv/argc are used.

XmPrintSetup then creates an unrealized ApplicationShell with the same name and class as the one given by the video display, on the print display and on the print screen specified.

An XmPrintShell is then created as a child of this toplevel shell, using XtCreatePopupShell, with the name print_shell_name, and using the args provided. It then realizes and maps the print shell, using XtPopup with XtGrabNone.

This way, application resource files and users can specify print specific attributes using the following syntax (if print_shell_name is "Print"):

Dtpad.Print*textFontList: somefont
*Print*background:white
*Print*highlightThickness:0

video_widget

A video widget to fetch app video data from.

print_screen

A print screen on the print display - specifies the screen onto which the new shell is created.

print_shell_name

Specifies the name of the XmPrintShell created on the X Print server.

args

Specifies the argument list from which to get the resources for the XmPrintShell.

num_args

Specifies the number of arguments in the argument list.

RETURN VALUE

The id the XmPrintShell widget created on the X Print Server connection, or NULL if an error has occured.

ERRORS/WARNINGS

None.

EXAMPLES

From the OK callback and the SetUp callback of the primary print dialog widget:

static void
printOKCB(Widget, XtPointer call_data, XtPointer client_data)
{
  AppPrint *p = (AppPrint *) client_data;
  DtPrintSetupCallbackStruct *pbs =
                         (XmPrintCallbackStruct *) call_data;

  /* connect if not already done.
     the print dialog callback always provides valid
             printer name, print display and screen
             already initialized: XpInitContext called */
 */
  p->print_shell = XmPrintSetup (widget, pbs->print_screen,
                                              "Print", NULL, 0);

  ...
}
