All,
We are developing a Qt3D application that uses many threads for geometry
generation. We have some questions regarding the thread-safety of the
library:
- Is it possible to use more than one QBuilder and call
finalizedSceneNode() from different threads (at the same time)?
- Do we need to spe

Hi
I was trying to capture audio using QAudioInput. But I get nothing in the
output buffer. Please see the attached code. I try to send it to google for
text recognition after recording but buffer itself is empty.
Platform: Ubuntu Linux 32bit 12.10 with Qt5.0

Ah, I think I got an idea from the docs.
Apparently, one cannot modify the layout of a widget after it has been set
as a QScrollArea content. Damned... this prevents me from dynamically
changing the content of the dock without recreating everything at each
update

It was meant to be used only in the run() method. And as Frank H. replied, it
prevents people from trying to put another thread to sleep
Tried, with no success.
Surprisingly, if I directly set my QWidget as the QDockWidget content, it
works.
But if I put a QScrollArea as the QDockWidget content, and my QWidget as
QScrollArea content, it does not work.
Something is wrong with the QScrollArea

Hi,
Do you want to force the thread to sleep (ie pause its execution for some
time) from the main thread? I do not think there is a generic solution, you
cannot force a thread to pause.
But:
- If the thread uses an event loop, you can have a QObject that you create
and move to this thread using
Try calling gridlayout->update() and see if that helps?

Dear all,
I am encountering the following issue using QGridLayout in a widget.
The QGridLayout is currently used for displaying labels along a grid with
two columns, in a subclassed QWidget. This QWidget was set as the widget of
a QSCrollArea, the QScrollArea is the content of a QDockWidget.

Hi folks!
Today some doubt has ocurred on my office. Suppose that for some
reason we need to sleep a thread (not the main thread) for some time
(eg. 100 ms). The QThread::wait(int) "provides similar functionality
to the POSIX pthread_join()" and this don't will sleep the target
thread, but the cal

Apologies I've only just spotted this thread. This was discussed on the
development@ list
I couldnot find gstreamer 0.10.38..So I installed 0.10.36 as gstreamer should
be <1.0 but still
getting the same error as mentioned below.
Any pointers to enable gstreamer in configure verbose output?
