Hi,
the following example fails after 9 loop iterations:

I am loading a QML document with the following structure:

At some point in the application I am iterating over all B components and
want to do:
qmlContext(B)->setContextProperty("bla", "value")
I need to assign different values to each instance of B. But I get

is there a way to set Qt::PreciseTimer as the default timer type for all
QTimer instances in an application? According to the QTimer documentation
[1], Qt::CoarseTimer is the default.
Thanks

Hi,
is there an easy way to register a QObject-derived class in the QML type
system so that I can instantiate it from within JavaScript code using
operator new?
function someJavaScriptFunction(){
var myObject = new MyClass("blabla");
// ...
}
Right now I am registering another class as

I know, but I wanted to use operator new in order to achieve a better look &
feel. Please note that this is/was easily possible in Qt Script. See the
code snippets at

what is the expected event execution order in the following scenario?

- Thread T2 sends an event E2 to T1 (queued)

You mean concatenating header and source files containing a Q_OBJECT macro
and feeding moc the result? I cannot imagine that this would be a safe
transformation in

Unless you build with link-time optimization enabled, I suppose. Because

Hello,
when configuring and building Qt, almost all top-level folders are
configurable. The mkspecs folder seems to be hardcoded. Is there a way to
move mkspecs, for instance into a subdirectory, so that the resulting folder
structure looks like:
Qt
+--bin
+--lib
+--res
+--mkspecs
+--xxx
I want to replace QML's console object with a custom implementation.
I have tried to replace the "console" property in the global object with not
luck.
I have tried to replace the method properties of the global console object

No, not complete. QJSEngine provides less APIs and less control of the script
execution and context arrangement. Whether your application is portable depends
on which features of QtScriptEngine you use.

Hi Volker,
