From f8c683f700a3fff30540ff343df2bfba15080e86 Mon Sep 17 00:00:00 2001 From: Tannin Date: Thu, 20 Jun 2013 21:55:37 +0200 Subject: - some fixes for qt5 compatibility - hook.dll no longer creates a dump and uninstalls it if an exception is reported that doesn't originate from it - NCC used read-only transactions again because otherwise solid archives become unusably slow. - removed the integrated nexus browser - the mod description and motd are now rendered in QTextBrowser. This (and the above) eliminates the dependency on qtwebkit - removed the direct file download for mod files - reduced CPU usage during downloads by invalidating only one column of the download list. This widget still needs to be replaced - added the complete filename as an option for the modname - applications that require elevation can now be started by invoking an elevated secondary ModOrganizer instance - MO will now register nexus file servers and provides a settings dialog to pick preferred servers. (This preference is not used yet) - worked around 1-2 bugs in QSortFilterProxy - handling of nxm links is now done by an external application. This allows the registration of different applications depending on the game - integrated fomod installer now displays the screenshot in a scalable view - bugfix: integrated fomod installer didn't name output files correctly if the name differs from the source name - bugfix: a successful login to nexus was (sometimes?) not correctly detected as a success - bugfix: top-level entries in QtGroupingProxy were sometimes incorrectly displayed as groups - bugfix: GetPrivateProfile... optimization could cause null-pointer indirection - bugfix: GetCurrentWorkingDirectory caused buffer overflow in case of pre-flighting (buffer size 0) - bugfix: configurator plugin now also uses qt5 (it's currently broken though) --- src/modeltest.cpp | 583 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 583 insertions(+) create mode 100644 src/modeltest.cpp (limited to 'src/modeltest.cpp') diff --git a/src/modeltest.cpp b/src/modeltest.cpp new file mode 100644 index 00000000..b2e495b6 --- /dev/null +++ b/src/modeltest.cpp @@ -0,0 +1,583 @@ +/**************************************************************************** +** +** Copyright (C) 2013 Digia Plc and/or its subsidiary(-ies). +** Contact: http://www.qt-project.org/legal +** +** This file is part of the test suite of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:LGPL$ +** Commercial License Usage +** Licensees holding valid commercial Qt licenses may use this file in +** accordance with the commercial license agreement provided with the +** Software or, alternatively, in accordance with the terms contained in +** a written agreement between you and Digia.
