From e35878bf57f4107fa1a49a8a4d552ea5ce1b53a9 Mon Sep 17 00:00:00 2001 From: Albert Astals Cid Date: Thu, 28 Dec 2017 17:51:43 +0100 Subject: [PATCH 1/1] CUPS: Rework set/clearCupsOption API Previously it was a bit awkward to use, you had to do QStringList cupsOptions = QCUPSSupport::cupsOptionsList(printer); QCUPSSupport::setCupsOption(cupsOptions, option, value); QCUPSSupport::setCupsOptions(printer, cupsOptions); now you simply have to do QCUPSSupport::setCupsOption(printer, option, value); Change-Id: Id31583f1ec72644791d82776debbae5583a2be54 Reviewed-by: Andy Shaw --- src/printsupport/dialogs/qprintdialog_unix.cpp | 4 +-- src/printsupport/kernel/qcups.cpp | 44 ++++++++++---------------- src/printsupport/kernel/qcups_p.h | 6 ++-- 3 files changed, 20 insertions(+), 34 deletions(-) diff --git a/src/printsupport/dialogs/qprintdialog_unix.cpp b/src/printsupport/dialogs/qprintdialog_unix.cpp index 47e2fa5..ab38c24 100644 --- a/src/printsupport/dialogs/qprintdialog_unix.cpp +++ b/src/printsupport/dialogs/qprintdialog_unix.cpp @@ -1417,9 +1417,7 @@ void QPPDOptionsModel::setCupsOptionsFromItems(QPrinter *printer, QOptionTreeIte QOptionTreeItemOption *itmOption = static_cast(itm);
