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.
For Qt 4.8.6 Qt Quick examples and demos located at QML Examples and Demos
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.

Does anyone know if an offline version of the latest PyQt4 and PyQt5 documentation is available somewhere on the Internet? I don't want to depend on whether I have a working Internet connection or not. I can of course grab it using wget or similar but I would prefer if I can do that the "normal" way (a PDF version would also be nice).
Note: Mny things are covered by the official Qt documentation (C++) however there are also things specific to Python. An example for such a treat is the fact that in C++ there are functions which have multiple overloaded versions while in Python such a thing is not possible. I find myself ever so often looking into the PyQt docs to see how this and that Qt thing looks like in Python.
The PyQt source releases contain the documentation in doc/html.
You can also use the Python builtin help() on a PyQt object - often that way you'll get more relevant information (like the exact Python signatures) compared to the documentation.
Qt comes with a dedicated program, called Qt Assistant, that can be used to browse the documentation off-line. I use it regularly. It's C++ only obviously.
I don't know where it is installed on your system but it may very well be in the same directory as the Qt Designer.

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 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'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 keep hearing that Flex is open source and I figured that a great way to learn about the inner workings would be to look at it. I can easily find the Flex SDK (http://opensource.adobe.com/wiki/display/flexsdk/Get+Source+Code), but I'm wanting to look at the class definitions for the MXML core library (like NumericStepper). Have I misunderstood, or is this kind of thing available somewhere?
Note, I'm looking for the source of some core MXML components so I can see how they work internally, not for the compiler's source. Does what I've linked above have what I'm looking for and I just can't find it in the director structure?
If you have installed the sdk or Flex builder all of the source files are installed locally on your computer, I believe.
I have flex builder 3 installed source is located here(depending on where you installed):
Source for flex 3 sdk
C:\Program Files\Adobe\Flex Builder 3\sdks\3.0.0\frameworks\projects\framework\src\mx
Source for flex 2 sdk
C:\Program Files\Adobe\Flex Builder 3\sdks\2.0.1\frameworks\source\mx
Hope this helps and alleviates the need to be online to view the source...
The source is found in the SVN repository that is here:
http://opensource.adobe.com/wiki/display/flexsdk/Get+Source+Code
Here's a direct link to the NumericStepper code: http://opensource.adobe.com/svn/opensource/flex/sdk/trunk/frameworks/projects/framework/src/mx/controls/NumericStepper.as
And here's the complete code of the framework: http://opensource.adobe.com/svn/opensource/flex/sdk/trunk/frameworks/projects/framework/src/mx/
The open source stuff appears to be at:
http://opensource.adobe.com/wiki/display/flexsdk/Downloads
I don't know if everything is available there yet, there may be issues with third-party stuff.
