I want to draw a network topology diagram with qt.
To simplify, I only need to draw routers, pcs and links between them, but I want the routers able to be dragged with links with mouse and to save all the widgets into a file and reopened if possible.
The diagram will be only part of my program, I plan to configure the routers and computers and complete other functions, too.
Any good links or suggestions?
I find using graphics libraries with a scene graph much easier to provide solutions for tasks you describe. Unfortunately QT and GTK lacks the flexibility that the Browser (SVG, Canvas) or Flash platform offer but there were some scene graph integration into QT and GTK with Clutter library can well be a viable option.
Here is something to investigate for QT:

I want to build a simple desktop application using QML (need nice transition animations), but i can't find any demos. The demos on qt docs website are using some shared files i can't find (and anyway they have both pro and QML pro while my application has only one view, so it's really overkill). I've found some code on github, but it seems like it's Qt5 only.
What i'm building is simple QML app with JS logic (remote JSON API calls) and some C++ code for platform specific stuff. Mb QML is just wrong idea for me?
Thanks.

QML .qmlproject files used for QML Viewer but you can use QDeclarativeView widget and load QML file on it as described here: Integrating QML Code with Existing Qt UI Code.

I am trying to visualize a VXML file, and have been searching for hours for a free and if possible open-source application, that would run on Windows, despite my intensive search I could not find any application.
Does anyone know a VXML visualizer?
Take a look at the Eclipse Voice Tools Project. This open source tool lets you visually develop a voice application that runs on any VoiceXML 2.1 compatible system. The only problem with this tool, and any other VoiceXML tool, is they store the information as meta-data that is translated to VoiceXML either at deployment or at run-time. This will lock you into a tool vendor since it will not be portable from one tool to another. There are not any tools, open source or commercial, that can take straight VoiceXML and visually represent a higher level abstraction of the voice application.

I'm writing a Qt application that uses a QWebView to host the UI. Similar to the ImageAnalyzer example in the Qt SDK samples.
I would like to test this UI using an automated method. A scripting interface like Selenium Web-Driver would be preferable.
Any recommendations/examples on how to do this?
Edit:
I'm looking for a solution can identify HTML elements via classes and id's so that it's maintainable and robust to change.
Tools like Sikuli (which are appearance based), don't satisfy this criterion. Note: I believe those are great for quick one-off scripting, they just don't work very well across many different platforms/configurations and over time for my purpose.
There is a WebDriver implementationfor Qt: https://github.com/cisco-open-source/qtwebdriver
Using Selenium tests and this WebDriver you can automate QtWebkit, widget and QML applications
So, I'm not sure this would satisfy your "Qt application that uses a QWebView" requirement, but when you say "I'm looking for a solution can identify HTML elements via classes and id's so that it's maintainable and robust to change." I can think of WatiR (which is a "browser driver").
It's open source so perhaps you could adapt it to drive your application.
There is also a .Net version called WatiN, but then you are restricted to Windows.

I am trying to find a good network monitoring system, easy to configure and to still have a lot of features. I want to try Nagio but it seems to be very complicated. I saw that are also a lot of systems direved from it (or work with it), like groundwork or Shinken.
Do you know or recommend a good solution for this?
I use GroundWork Community version. It runs Nagios inside already. Very hand one try it out.
you can use zenoss , monitoring system , groundwork community or enterprise
opsview etc
I would recommend New Relic. It is super easy to use.

I've decided to rewrite most of my distributed server programs in Go to replace the existing c# based ones.
Can someone point me to a Go TCP libs or a Go general network programming lib.
Thanks
Edi: ... and how do i complile this code is visual stuido 2008? Thanks
Here's the official API docs for the net package.
Regarding how to compile: See the installation guide. As of yet there doesn't seem to be an obvious way to compile in VS:
The Go tool chain is written in C. To
build it, you need to have GCC, the
standard C libraries, the parser
generator Bison, and the text editor
ed installed.
So in order to develop on Windows, the easiest route would be to use cygwin.
Depending on the needs of your distributed software, you may also want to check out the rpc package which makes it quite easy to register an object's public methods and call them remotely.
