Print WebViewer on macOS in FileMaker


Today an user send us a script which does printing of a webviewer with some report (in HTML) to a PDF file. The code works pretty well and prints automatically dozens of reports to PDF files:

# Check plugin version installed to use right key

Set Variable [ $_MBS_Version ; Value: MBS("Version") ] 

Set Variable [ $_MBS_Version_asNumber ; Value: Substitute ( GetAsNumber ( $_MBS_Version ) ; "?" ; 0 ) ] 

If [ MBS("isRegistered") ≠ 1 ] 

If [ $_MBS_Version_asNumber >= 7 ] 

# Version 7 with newer code

Set Variable [ $_MBS ; Value: MBS("Register"; "ABC"; "Complete"; "5 seats"; 201803; "###") ] 

Else

# Version 6 with older code

Set Variable [ $_MBS ; Value: MBS("Register"; "ABC"; "Complete"; "5 seats"; 201702; "xyz") ] 

End If

End If

# Destination file path, could be a parameter to the script.

Set Variable [ $_Path_Destination_Complete ; Value: "/tmp/test.pdf" ] 

# Page to load and print

Set Variable [ $URL ; Value: "https://www.mbsplugins.de" ] 

# Check plugin version needed for FileMaker 16

If [ GetAsNumber ( Get(ApplicationVersion) ) >= 16 and $_MBS_Version_asNumber < 7,4 ] 

Show Custom Dialog [ "Process: Error" ; "Filemaker 16 or greater requires MBS Plugin version 7.4 or higher." ] 

Halt Script

End If

# Set print parameters

Set Variable [ $_MBS ; Value: MBS( "WebView.SetPrintParameter"; "topMargin"; 0 ) ] 

Set Variable [ $_MBS ; Value: MBS( "WebView.SetPrintParameter"; "bottomMargin"; 0 ) ] 

Set Variable [ $_MBS ; Value: MBS( "WebView.SetPrintParameter"; "leftMargin"; 0 ) ] 

Set Variable [ $_MBS ; Value: MBS( "WebView.SetPrintParameter"; "RightMargin"; 30 ) ] 

If [ $_MBS_Version_asNumber >= 7,4 ] 

Set Variable [ $x ; Value: 0 ] 

Set Variable [ $y ; Value: 100 ] 

Set Variable [ $w ; Value: 970 ] 

Set Variable [ $h ; Value: 440 ] 

# Create a webviewer via plugin to use older WebKit which can print

Set Variable [ $$web ; Value: MBS("Webview.Create"; 0; $x; $y; $w; $h) ] 

Set Variable [ $error ; Value: MBS("IsError") ] 

If [ $error = 0 ] 

# Load URL

Set Variable [ $_MBS ; Value: MBS( "WebView.LoadURL"; $$web; $URL) ] 

# Wait for loading

Set Variable [ $_WebViewer_isLoading ; Value: True ] 

Loop

Pause/Resume Script [ Duration (seconds): ,2 ] 

Exit Loop If [ MBS( "WebView.IsLoading"; $_theWebViewerID ) ≠ 1 ] 

End Loop

# print webviewer

Set Variable [ $_MBS ; Value: MBS( "WebView.PrintToFile"; $$web ; $_Path_Destination_Complete ) ] 

Set Variable [ $error ; Value: MBS("IsError") ] 

# close webviewer

Set Variable [ $r ; Value: MBS( "WebView.Close"; $$web) ] 

End If

Else

# Print WebViewer Contents to tmp folder

Set Variable [ $_theWebViewerID ; Value: "web" ] 

# print webviewer

Set Variable [ $_MBS ; Value: MBS( "WebView.PrintToFile"; $_theWebViewerID ; $_Path_Destination_Complete ) ] 

Set Variable [ $error ; Value: MBS("IsError") ] 

End If

If [ $error ] 

Show Custom Dialog [ "Process: Error" ; List ( "Failed to save file [" & $_Path_Destination_Complete & "]" ; MBS("Text.RemovePrefix"; $_MBS… ] 

Halt Script

End If

 

As you see they use either an existing WebViewer on the layout or use the plugin provided one if possible. As WebKit 2.x does not print, but FileMaker 16 only uses the new version, we have to make a webviewer ourselves via plugin functions using older WebKit 1.x.
