NAME
XmPrintPopupPDM - Send a notification for the PDM to be
popped up
SYNOPSIS
#include <Xm/Print.h>
XtEnum XmPrintPopupPDM(
Widgetprint_shell,
Widgetvideo_transient_for);
VERSION
This page documents Motif 2.1.
DESCRIPTION
A convenience function that sends a notification to start a
Print Dialog Manager on behalf of the application,
XmPrintPopupPDMhides the details of the X selection
mechanism used to notify the PDM that a new dialog must be
popped up for this application.
XmPrintPopupPDM sends a selection request to either the
print display of the print shell, or the video display of
the transient_for video widget (depending on the environment
variable XPDMDISPLAY, which can only takes the value "print"
or "video"), asking for the PDM windows to be popped up on
behalf of the app.
Return right away with status of XmPDM_NOTIFY_FAIL(e.g. if
the function couldn't malloc memory for the selection value,
or if XPDMDISPLAYis not "print" or "video") or with
XmPDM_NOTIFY_SUCCESS, which only means a "message" was sent
out to the PDM specified by XPDMSELECTION, not that it's
already up on the screen yet.
In order to know if the PDM is up, or not running, the
application must register a XmNpdmNotificationCallbackwith
the Print Shell.
XmPrintPopupPDM puts up an InputOnlywindow on top of the
dialog, so that the end user doesn't use the print setup
dialog while the PDM is trying to come up. This window is
automatically removed when the shell is about to call the
callback for the first time.
print_shell
The Print Shell used for this print job and
context.
video_transient_for
The video widget dealing with application print
setup.
