From: Bradley T. Hughes Date: Wed, 29 Feb 2012 14:23:22 +0000 (+0100) Subject: Add a QPlatformPrinterSupportPlugin for Cocoa X-Git-Tag: qt-v5.0.0-alpha1~275 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4f246bceb5958cb7ae86d7c5d59c78cad25bdd56;p=profile%2Fivi%2Fqtbase.git Add a QPlatformPrinterSupportPlugin for Cocoa This is used to create the actual QPrintEngine and to query the system about printer information. The QCocoaPrinterSupport actually lives in the Cocoa platform plugin, so the QCocoaPrinterSupportPlugin uses the createPlatformPrinterSupport() function in the QPlatformNativeInterface (since the latter is a QObject). This is done to avoid adding a printing related virtual function to QPlatformIntegration (since we have plans to do a new printing API in the future).
