* Update documentation snippets related to QDebug.Friedemann Kleint2015-04-011-3/+4
| | | | | | | | Use QDebugStateSaver to store the formatting state and fix the return statement to return the unmodified stream. Change-Id: I476d13c5487a89f263dcc11334fc67c85d9433f5 Reviewed-by: Kai Koehne <kai.koehne@theqtcompany.com>

* Update copyright headersJani Heikkinen2015-02-111-5/+5
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Add QtInfoMsgKai Koehne2015-01-091-1/+13
| | | | | | | | | | | | | | Add an 'info' message type that can be used for messages that are neither warnings (QtWarningMsg), nor for debugging only (QtDebugMsg). This is useful mainly for applications that do not have to adhere to the 'do not print anything by default' paradigm that we have for the Qt libraries itself. [ChangeLog][QtCore][Logging] QtInfoMsg got added as a new QtMsgType. Use the new qInfo(), qCInfo() macros to log to it.

* Support setting a default severity level for QLoggingCategoryKai Koehne2014-07-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Allow to alter the default configuration for categories by passing a message type: All message types with lower severity are disabled in this category. This is useful for libraries, which shouldn't mess with the category registry itself: Setting rules, a category filter ... might cause conflicts and ordering problems, so this API should be reserved to the specific application. For the Qt categories, we have code in the default category filter that disables the 'debug' category. However, this is hardcoded, and there's no way so far for other libraries to get the same behavior. With this patch one can get the same behavior: Q_LOGGING_CATEGORY(DRIVER_USB_EVENTS, "driver.usb.events", QtWarningMsg); [ChangeLog][QtCore][Logging] Added QtMsgType argument to QLoggingCategory constructor and Q_LOGGING_CATEGORY macro that controls the default category configuration.

* Improve QLoggingCategory example code in documentationKai Koehne2014-07-151-14/+14
| | | | | | | | | | | | | | Don't use a qt.* category in the user documentation: These should be reserved to Qt internal use, and also have special semantics (QtDebugMsg by default off) that might lead to confusion. Also, adapt the camel case naming convention for logging categories defined by the macros. This was the (although somewhat controversial) result of a recent discussion on the development mailing list.

* Allow printf style for qCDebug, qCWarning, qCCritical macrosKai Koehne2014-01-211-0/+21
| | | | | | | | | | | | | | | | | Add support for using qCDebug and friends in the 'printf style' way. This allows an almost mechanical conversion of existing qDebug, qWarning, qCritical macros, and allows avoiding the size overhead the streaming style incurs (mostly due to inlined QDebug code). To handle this gracefully we require variadic macros (part of C++11/C99). For compilers not supporting variadic macros we fall back to checking the category in QMessageLogger. [ChangeLog][QtCore][Logging] Allow qCDebug macros to be used in a printf style. Change-Id: I5a8fb135dca504e1d621bb67bf4b2a50c73d41b9 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* Import qlogger frameworkKai Koehne2013-09-201-0/+113
Merge most parts of the qlogger framework from git://gitorious.org/qtplayground/qlogger.git The categorized logging feature is a replacement for qDebug, qWarning and friends. With logging statements in an app/library, a developer can turn on the statements they care about and turn off the ones they don't. Most work for this was done by Wolfgang Beck and Lincoln Ramsay.
