The pool contains: 1) All built-in code styles (Qt/GNU) 2) All custom code styles (which will be added dynamically) 3) A global code style If the code style gets a pool (setCodeStylePool()) it means it can behave like a proxy to one of the code styles from that pool (ICodeStylePreferences::setCurrentDelegate()). That's why the global code style gets a pool (it can point to any code style from the pool), while built-in and custom code styles don't get a pool (they can't point to any other code style). The instance of the language pool is shared. The same instance of the pool is used for all project code style settings and for global one. Project code style can point to one of built-in or custom code styles or to the global one as well. That's why the global code style is added to the pool. The proxy chain can look like: ProjectCodeStyle -> GlobalCodeStyle -> BuildInCodeStyle (e.g. Qt). With the global pool there is an exception - it gets a pool in which it exists itself. The case in which a code style point to itself is disallowed and is handled in ICodeStylePreferences::setCurrentDelegate(). */ // built-in settings // Qt style CppCodeStylePreferences *qtCodeStyle = new CppCodeStylePreferences(); qtCodeStyle->setId("qt"); qtCodeStyle->setDisplayName(tr("Qt")); qtCodeStyle->setReadOnly(true); TabSettings qtTabSettings; qtTabSettings.m_tabPolicy = TabSettings::SpacesOnlyTabPolicy; qtTabSettings.m_tabSize = 4; qtTabSettings.m_indentSize = 4; qtTabSettings.m_continuationAlignBehavior = TabSettings::ContinuationAlignWithIndent; qtCodeStyle->setTabSettings(qtTabSettings); pool->addCodeStyle(qtCodeStyle); // GNU style CppCodeStylePreferences *gnuCodeStyle = new CppCodeStylePreferences(); gnuCodeStyle->setId("gnu"); gnuCodeStyle->setDisplayName(tr("GNU")); gnuCodeStyle->setReadOnly(true); TabSettings gnuTabSettings; gnuTabSettings.m_tabPolicy = TabSettings::MixedTabPolicy; gnuTabSettings.m_tabSize = 8; gnuTabSettings.m_indentSize = 2; gnuTabSettings.m_continuationAlignBehavior = TabSettings::ContinuationAlignWithIndent; gnuCodeStyle->setTabSettings(gnuTabSettings); CppCodeStyleSettings gnuCodeStyleSettings; gnuCodeStyleSettings.indentNamespaceBody = true; gnuCodeStyleSettings.indentBlockBraces = true; gnuCodeStyleSettings.indentSwitchLabels = true; gnuCodeStyleSettings.indentBlocksRelativeToSwitchLabels = true; gnuCodeStyle->setCodeStyleSettings(gnuCodeStyleSettings); pool->addCodeStyle(gnuCodeStyle); // default delegate for global preferences d->m_globalCodeStyle->setCurrentDelegate(qtCodeStyle); pool->loadCustomCodeStyles(); QSettings *s = ICore::settings(); // load global settings (after built-in settings are added to the pool) d->m_globalCodeStyle->fromSettings(QLatin1String(CppTools::Constants::CPP_SETTINGS_ID), s); // legacy handling start (Qt Creator Version < 2.4) const bool legacyTransformed = s->value(QLatin1String("CppCodeStyleSettings/LegacyTransformed"), false).toBool(); if (!legacyTransformed) { // creator 2.4 didn't mark yet the transformation (first run of creator 2.4) // we need to transform the settings only if at least one from // below settings was already written - otherwise we use // defaults like it would be the first run of creator 2.4 without stored settings const QStringList groups = s->childGroups(); const bool needTransform = groups.contains(QLatin1String("textTabPreferences")) || groups.contains(QLatin1String("CppTabPreferences")) || groups.contains(QLatin1String("CppCodeStyleSettings")); if (needTransform) { CppCodeStyleSettings legacyCodeStyleSettings; if (groups.contains(QLatin1String("CppCodeStyleSettings"))) { Utils::fromSettings(QLatin1String("CppCodeStyleSettings"), QString(), s, &legacyCodeStyleSettings); } const QString currentFallback = s->value(QLatin1String("CppTabPreferences/CurrentFallback")).toString(); TabSettings legacyTabSettings; if (currentFallback == QLatin1String("CppGlobal")) { // no delegate, global overwritten Utils::fromSettings(QLatin1String("CppTabPreferences"), QString(), s, &legacyTabSettings); } else { // delegating to global legacyTabSettings = TextEditorSettings::codeStyle()->currentTabSettings(); } // create custom code style out of old settings QVariant v; v.setValue(legacyCodeStyleSettings); ICodeStylePreferences *oldCreator = pool->createCodeStyle( "legacy", legacyTabSettings, v, tr("Old Creator")); // change the current delegate and save d->m_globalCodeStyle->setCurrentDelegate(oldCreator); d->m_globalCodeStyle->toSettings(QLatin1String(CppTools::Constants::CPP_SETTINGS_ID), s); } // mark old settings as transformed s->setValue(QLatin1String("CppCodeStyleSettings/LegacyTransformed"), true); // legacy handling stop } // mimetypes to be handled TextEditorSettings::registerMimeTypeForLanguageId(Constants::C_SOURCE_MIMETYPE, Constants::CPP_SETTINGS_ID); TextEditorSettings::registerMimeTypeForLanguageId(Constants::C_HEADER_MIMETYPE, Constants::CPP_SETTINGS_ID); TextEditorSettings::registerMimeTypeForLanguageId(Constants::CPP_SOURCE_MIMETYPE, Constants::CPP_SETTINGS_ID); TextEditorSettings::registerMimeTypeForLanguageId(Constants::CPP_HEADER_MIMETYPE, Constants::CPP_SETTINGS_ID); }
