Igor,
You might want to look at QCryptographicHash and then truncate or
concatenate to N chars. Either that or QDateTime using the epoch. Your
solution depends on how you are defining unique. Either way should be
fairly simple.

Hi.
Does Qt have something for generating unique string of N chars?
Or maybe does somebody know simple way to do it?

In a last ditch effort, I got this to work.
I needed to change my m_dests to m_videoSurfaces, then set the source of the
dest to this. I only figured this out by reviewing the VideoOutput source code.
I had seen a statement about providing a writable mediaObject or videoSurface

One possible way would be to connect the rowsRemoved signal for the model to a
slot that calls model.select() or some other function that resets the model and
updates the view.

Hi.
How to correctly remove row from QSqlTableModel?
I’ve used removeRow() and removeRows() but they are half-worked. They remove
row from the database table and in the view I see that data is gone, but empty
row in the view is still displayed...___

I think the Qt libraries in Ubuntu's repositories haven't been updated and
probably won't be until the next Ubuntu version.
That was the reason why I used the installer from Qt's website instead. It
has its own updater and you can stay up-to-date.

I still see the problem with the latest version of QtCreator 3.0.1, (file
system browser and file-open dialog) and I upgraded all my KDE ubuntu

I wanted to update from Qt 5.2.0 to Qt 5.2.1 on Linux.
I ran MaintenanceTool and it spent about 3 minutes contacting the server
before it told me it had to update
itself. Then it did, it restarted, spent another 3 minutes looking for
updates, and the told me I had one for QtCreator. But no update
When I first downloaded Qt5 that was the case with me too. But I found a
bug report about it and since a certain version (I don't remember which) it
seems to have been fixed, as it follows my KDE settings. Make sure you have
the latest version.

Yes, sure.

In the KDE3 days, whenever my source-built (or binary downloaded) versions
of Qt4 behaved differently than the debian builds with respect to my KDE
preferences for mouse-click-open files and folders behaviour, I could fix
it by running "qtconfig" and changing it from single to a double-click

If you register the class with QMetaType with Q_DECLARE_METATYPE(Class*),
you can then call QMetaType::type("Class"). With the returned int, you can
then call QMetaType::metaObjectForType(integer). I think this is what you

I'm not 10% udnerstanding your intentions, but this might help. You can create
any QObject through QMetaObject by the class name, then get the meta object for
the created object. Look at QMetaObject::newInstance(..)
You need a "class factory" design pattern.
Here is an example:

Hi,
The SDK version is available via:

see qtandroidextras/src/androidextras/android/qandroidfunctions.h
There might be a tiny bit more information hidden in private headers but they
come along with the usual "use at your own risk we may change it" statement.
