XmPrintPopupPDM(3)XmPrintPopupPDM(3)NAMEXmPrintPopupPDM — Send a notification for the PDM to be popped up
SYNOPSIS
#include <Xm/Print.h>
XtEnum XmPrintPopupPDM(
Widgetprint_shell,
Widgetvideo_transient_for);
DESCRIPTION
A convenience function that sends a notification to start a Print Dia‐
log Manager on behalf of the application, XmPrintPopupPDM hides 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 func‐
tion couldn't malloc memory for the selection value, or if XPDMDISPLAY
is 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 XmNpdmNotificationCallback with the Print Shell.
XmPrintPopupPDM puts up an InputOnly window 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.
RETURN VALUE
Returns XmPDM_NOTIFY_SUCCESS if the function was able to send the noti‐
fication out to the PDM process, XmPDM_NOTIFY_FAIL otherwise.
ERRORS/WARNINGS
Not applicable.
EXAMPLES
Example of callback from a Print set up dialog box "Setup..." button:
PrintSetupCallback(print_dialog...)
/*-------------*/
{
if (XmPrintPopupPDM (pshell, XtParent(print_dialog)) !=
XmPDM_NOTIFY_SUCCESS) {
/* some error dialog */
}
}
Example of XmNpdmNotificationCallback from a Print Shell:
pdmNotifyCB(print_shell...)
{
XmPrintShellCallBackStruct * pr_cb = ...
switch (pr_cb->reason) {
case XmCR_PDM_NONE:
/* no PDM available */
PostErrorDialog(...);
break;
case XmCR_PDM_VXAUTH:
/* PDM is not authorized ... */
PostErrorDialog(...);
break;
case XmCR_PDM_UP: the PDM is up and running
/* everything is fine */
break;
default: /* other cases */
}
}
