I wanted a convenient way to manage giving the user a option to print any content to a screen preview, file, email or a printer for any print job in the solution. What I came up with is what follows.
First, you'll need a UI, mine looks like this (red text added to show global variables):
Then you need a method to show that as a dialog -- this one returns true if the user clicked OK, using a global to store the dialog result from the dialog itself:
-
var winloc = globals.dialog_getLocation();
-
application.showFormInDialog(forms.print_SelectDestination,null,null,500,360,'Print',true,false,true);
-
-
if( globals.print_destination_result == 1 )
-
return true;
-
return false;
Then you need a method to call to actually do a print job. Before doing the print job, you'll need to set the foundset set on the form you're planning on printing, then pass the form name to this method:
-
var frmName = arguments[0];
-
var printCurrentOnly = ( arguments[1] == null || arguments[1] == true );
-
-
if( !globals.print_destination_select() )
-
return;
-
-
if( globals.print_destination == 'printer' )
-
{
-
forms[frmName].controller.print( printCurrentOnly );
-
return;
-
}
-
if( globals.print_destination == 'pdf' )
-
{
-
var f = "";
-
if( globals.util_isValidString( globals.print_destination_pdf ) )
-
f = globals.print_destination_pdf;
-
else
-
f = plugins.file.createTempFile( "preview", ".pdf" );
-
-
var success = plugins.pdf_output.startMetaPrintJob();
-
if( success )
-
{
-
forms[frmName].controller.print(printCurrentOnly,false,plugins.pdf_output.getPDFPrinter() );
-
}
-
var pdf = plugins.pdf_output.endMetaPrintJob();
-
plugins.file.writeFile( f, pdf );
-
globals.util_openFile( f );
-
return;
-
}
-
if( globals.print_destination == 'email' )
-
{
-
var success = plugins.pdf_output.startMetaPrintJob();
-
if (success)
-
{
-
forms[frmName].controller.print( printCurrentOnly,false,plugins.pdf_output.getPDFPrinter());
-
}
-
var thePdf = plugins.pdf_output.endMetaPrintJob();
-
var attachment1 = plugins.mail.createBinaryAttachment( 'output.pdf', thePdf );
-
var success = globals.mail_send( globals.print_destination_email_to, globals.print_destination_email_from, globals.print_destination_email_subject, globals.print_destination_email_body, null, null, new Array(attachment1) );
-
if( !success )
-
{
-
globals.dialog_error( "Unable to send mail." );
-
}
-
return;
-
}
Of course, there's a few minor details I left out. You need to set the destination global in the dialog. You need a bit of UI coding to highlight and select destinations. You'll notice in the code that if you select PDF as a destination, and leave the filename blank, it will create a temp file and open it. It works very nicely, however.
Where is the authentication done for your smtp server? Do you hide that in your global method “mail_send” ?
I wrap some built in Servoy methods in my own to provide flexibility in a solution. In this case, my “mail_send” method really just forwards to the built-in version. I usually configure mail authentication in the servoy.properties file on the server. You can’t set the smtp auth props through the preference window, but you can in the actual property file.
