基于QT开发的第三方库

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

Qtilities v1.4 is now available.

The main reason for the release is to add LGPL v2.1 to the list of licenses under which Qtilities is available. The project also underwent some additional changes, described on the "What's New" documentation page.

In addition, a handful of code changes were introduced. For details please see the detailed changelog.

As always, make sure the get in touch if you have problems or suggestions:

又一个Qt的扩展库

http://libqxt.org.

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.

QSint contains high-quality widgets for using in Qt applications, such as color pickers, Windows Vista/7-styled action boxes, recent files menus etc.

You can find it at: http://sintegrial.com/qsint

Version 0.2.beta contains following widgets:

ActionLabel

ActionBox

ActionGroup

ActionPanel

ColorButton

ColorGrid

RecentFiles

ScrollPanner

TabListMenu

WidgetPopup

The distribution contains source codes, examples and documentation. Also, Qt Desinger plugin is available.

Screenshot of QSint::ActionPanel:

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:

This class can be used to give move and resize ability to any top level QWidget with Qt::FramelessWindowHint flag set.

No need to change your existing code.

Its very easy to use. Just two lines of code.

Qt Code:
Switch view

QWidget* myWidget = new QWidget;

FramelessHelper fh;

fh.activateOn(myWidget);

To copy to clipboard, switch view to plain text mode

Only tested on Ubuntu 10.10.

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 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 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!

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.
