Qt的三方库

QxOrm

QxOrm is a new
open source ORM (Object Relational Mapping) C++ library designed to provide :

* Persistence (based
on QtSql Qt module)

* Serialization (xml
and binary, based on boost::serialization)

* Reflection (invoke
class methods and access to properties)

QxOrm has been tested on Windows
(Visual C++ 2008 and 2010) and Linux (GCC 4.4.1).

QxOrm is based on a simple and non intrusive 'setting function'
(that can be compared with Hibernate Xml Mapping file).

A quick sample (and a tutorial) is avaible on this web site (only in french, an english translation is in progress...) : http://www.qxorm.com

Fervor

Fervor is a software library that you include into your own Qt-based application in order to
enable the application to automatically check for updates and suggest to install them.

When installed and enabled, Fervor downloads a "flavoured" RSS feed (dubbed "appcast") and checks whether an update to the application
is available. The RSS feed ("appcast") lists various versions of the application ("1.0", "1.1", "2.0", ...) that are available for download.

When a newer version of the application is found in the "appcast" (e.g. the user is using 1.0, and 1.1 is available), a dialog is presented
to the user (see below for example) that allows the user to choose whether he/she wants to install the update, be reminded about the update later, or skip a particular proposed version altogether. A dialog also shows some release notes about the proposed update
that help the user to choose whether or not to install an update.

At the moment, Fervor is not as cool as Sparkle -- it is not able to install the actual update
automatically (the user is given an option to download and install the update manually). Pull requests with unattended install modules for

.dmg

.pkg

(Mac
OS X),

QDeviceWatcher

It's my project: https://github.com/wang-bin/qdevicewatcher
It works fine on linux and windows. I have tested on my ubuntu and win7. Usually you just need the signals deviceAdded(const
QString& device) and deviceRemoved(const QString& device) in QDeviceWatcher.

To detect the device changes, i use netlink in linux(kernel 2.6) and internel window in windows.

In windows, I tried two method, QCoreApplication::winEventFilter(MSG* msg, long* result) and QWidget::winEvent(MSG*
msg, long* result). I hope my class is just a subclass of QObject, and do not use GUI module, so I started to find other ways. At last I refer to qdrive project: https://gitorious.org/qdrive/qdrive.

VistaGlassButton widget for Qt 4

For a current project I subclassed a QPushButton and re-painted it to look like a Vista
Aero glass button. You use it like a normal QPushButton, except there are two public methods - setColor(QColor color) and setShadow(QColor shadow). Color is the red area in the image below, Shadow is the black center. Anyway, I thought it might come in handy
for people wanting a look like this or for anyone wondering how to go about redrawing a widget:

GICS - Graphical Instruments and Components Solution

Tegeosft is
proud to release its first public version (beta) of GICS,
a library offering a set of vectorial graphical instruments. A framework allowing to build other instruments easily (with the help of base components) is part of the library too.

GICS, which stands for "Graphical Instruments and Components Solution", is based
on Qt's GraphicsView and is available under two licenses : either the GNU/GPLv3 or a Commercial one.

This first version, which acts more or less like a technological preview, provides
a gauge, a level indicator, a LCD, a LED, a button and a slider. These instruments use SVG skins for their graphical appearance.

To be noted that in a near future, the skin system will be reworked


To be noted too that a
little demo of GICS is available.

QVision

QVision is
a library for computer vision, image/video processing, and scientific computing.

It is based on (or extends) the Qt library. It offers wrapper classes and functions for BLAS, LAPACK, MKL, Octave, and GSL functionallity (matrices, vectors, etc...).

It also offers wrappers for OpenCV and IPP image libraries functionallity.

We have released version 0.5.2, which is already stable enough to be used.

You can check the documentation here.

Conan 1.0.0

Conan v1.0.0 - Connection analyzer for Qt has been released! Conan is a C++ library
that provides a single widget that can be used to track down problems related to signal/slot connections. It is real easy to use and has helped me locate multiple duplicate signal connection in Qt's own libraries. So if you ever need some signal-slot introspection,
try Conan. I hope you will find it usefull!

This release consists of a source code package and a win32 demo application. It is available under GPL at SourceForge.

Here is a small excerpt from the readme:

Conan 1.0.0 - Connection analyzer for Qt 4.6.0 - Qt 4.7.0

---------------------------------------------------------

Conan is a C++ library that provides run-time introspection of object

hierarchies, object inheritance, signal/slot connections, and signal

emissions.

Conan contains a single widget (conan::ConanWidget) that provides the

following functionality:

-object hierarchies can be added, discovered, browsed and exported to XML

-signals/slots, including active connections, can be examined

-any signal/slot connection can be disconnected

-duplicate connections can be found

-signal emissions can be monitored and logged

See /doc/html/index.html for detailed information.

Conan has been used to identify multiple duplicate connections in the source code of Qt!

Q7Goodies - Windows 7 features for Qt

I'd like to introduce you Q7Goodies: a new Qt add-on, that adds Windows 7 features to your application. It
integrates seamlessly with existing applications by encapsulating complexity and using Qt design patterns and API style. You can use: jump list, taskbar thumbnails, thumbnail toolbar and more in a Qt way with just a few additional lines of code.



Jump List - Your application's own start menu.



Tabbed Thumbnails - Any widget displayed as a separate thumbnail.



Thumbnail Toolbar - Quick access to key commands.



Thumbnail Progress Bar - Progress information that's always visible.

Overlay Icon - Status or notifications directly on the taskbar.

It doesn't add runtime dependency on Windows 7 libraries (DLLs), so software incorporating Q7Goodies can be
run on older Windows version. Q7Goodies comes with the full source code and a commercial royalty-free
license.
