I'm developing a program using PyQt4 and sqlite,
I want to include a small sqlite browser/editor/manager, just like sqliteman or sqlitebrowser,
are there any one written by pyqt?
You might want to take a look at the C++ SQL Browser demo shipped with Qt, and perhaps port it to Python.
The Eric Python IDE has a sql browser. It is open source and it's been written by pyqt.

Is it possible to embed QtDesigner into a PyQt application. I did some searching but can't really find any examples. Found lots about using the interface API but not really how to get the interface in the first place.
You will need to make 3 steps:
Get QtDesigner & QtCreator source
Create bindings from QtDesigner C++ code to python using SIP or Shiboken
Look at QtCreator source of how to embed QtDesigner into your application
I don't think its possible to do it without the source code. I doubt Qt will hand it out either. https://github.com/qt-creator/qt-creator is the source for QtCreator, but I could not find anything similar for QtDesigner.
I need to integrate an editor into a window/dialog in my PyQt4 application.
It needs to support syntax highlighting for Python, Java and C++. It should run under Linux and ideally windows.
What would you suggest and where can I find the API and instructions?
I was thinking about Katepart, but I can't find instructions for it.

I need to play sounds under Qt with control of volume and panning. QSound doesn't do it, phonon may be too much for only this so I thought I'd try the native api.
eeermm, in Mac I have no idea, is there some simple interface to invoke on c++? (I've seen all this NSSound stuff but I am not familar with Objective C and I am not sure if it's possible to mix code (under QtCreator)) my idea would be to a module with simple native api calls to system features not found on Qt.
Thanks!
Qt AudioEngine in Qt5 will do this.
If you're using Qt4, making a single 'Objective-C++' file (extension .mm) which can be called from Qt, but makes NSFoo calls, is easy and works well. The header file should be plain C++, and everything will work together.
I am using Qt in order to build a cross platform GUI app (Windows and Mac). I want to be able to update the app efficiently and automatically whenever there is a new patch available.
I saw this post which got me to take a look at WyBuild. It looks great and probably what I may end up using for the Windows version but what about Mac? What are some alternatives available to me?
I've just started developing a Qt-based autoupdater called Fervor for my own needs. You can try it out, contributions are more than welcome too.
For Mac the best choice is Sparkle used by WebKit, Adium, Cyberduck and more. Its only for Mac but I guess native look matters on Mac a lot.
Not familiar with WyBuild so cannot comment. Sparkle is a fine choice but the poster preferred a single app for both platforms. BitRock InstallBuilder contains an autoupdater written in Qt that can be used independently (disclaimer, I am the original BitRock developer). It is a commercial app, but we have free licenses for open source projects.
There is Updatenode which seems to provide a real Qt cross-platform solution.
It comes with a prebuilt client for Windows, Mac and Linux. The online service lets you manage updates very easy and are able to see good charts of your application usage.
And here another one of the possibilities:
Using the Qt Installer Framework: It provides installers for Windows/Linux/Mac with an build-in updater. If you need an example - The MaintenanceTool of your Qt-Installation uses the framework.
To get an auto-updater from it, all you need to do is:
Create an online installer (Just check the documentation, it's not that hard)
Use the maintenancetool in your application to check for updates.
This cane be done using my QtAutoUpdater. Go there for more information about the whole process
If new updates are available, the maintenancetool can be started in updater mode to install the update
Update the online repository - and your update is out.
Advantages:
Installer and updater in 1 tool - this means less work for you
Easy to use (with or without the QtAutoUpdater library)
Cross-Platform for all desktop platforms supported by Qt
The installer itself is a Qt original
Disadvantages:
No "native" installers (i.e. no .msi on windows or .deb on ubuntu)
Must be used together - if you want to use the update feature, you have to use the framework as installer
This may be obvious, but for Linux you can use the built in package manager. For example, apt-get, yum, pacman, or what have you.
I'm planning to use Sqlite but I don't know how to integrate it to visual studio or use it. Any help please... thanks.
I really recommend using System.Data.Sqlite ( http://sqlite.phxsoftware.com).
Have been using it for quite some time and it works great every time! You can create tables using the designer, similar to for MSSQL etc. Recommended++
Depends on how you want to use it. The easiest is to get the amalgamation version - this version "contains all preprocessed C code combined into a single source file", meaning you have a single .h and .c file to add to your project. This is the officially recommended practice.
If you want to build a "proper" library or link against SQLite dynamically, you have a bit more work ahead, since there's no VS project/solution files included with SQLite. You'll have to set up your own library project, add the correct files from the sqlite-source-x.y.z.zip file, and set this project as a dependency on your main project. Doing this is actually officially discouraged.
EDIT:
Forgot to mention that the above solution is assuming C/C++, as OP didn't specify language.
use System.Data.Sqlite
System.Data.SQLite is an ADO.NET provider for SQLite.
