[quote author="Arukas" date="1326976934"]I don't agree. I tried many things, and I eventually removed the show. "Here's a link to some example code.":http://dl.dropbox.com/u/481280/layoutDeleter.zip It doesn't matter that I use a QWidget or not, the layout is still not deleted from the GUI. [/quote] I inspected your code, and that's not actually what I meant. please check "this":http://dl.dropbox.com/u/3699382/layoutDeleter2.zip and be noted that any layout instance will be deleted as soon as place holder widget is gone. And see the difference and wanna hear your review on it.

I find it surprising that a patch should be necessary. This ought to be something that can be overridden by environment variables.

I ran into this problem again. I wish I knew what I was doing wrong. I am using events to cause graphic item position changes. It's like the scene's BspTreeIndex needs to refresh it's cache. I am guessing that Qt assumes an order and I am violating it. Anyhow, I will drop back to QGraphicsScene::NoIndex. Hopefully I won't get too much of a performance penalty.

Did not know that. Figured it did, but now I know for sure. Thanks!

There still is no need to do expensive stuff needlessly just because you need to do other expensive stuff anyway.

Thanks Volker, I'll do this way and keep this thread updated.

Thank u :)

I would recommend against using toLocal8Bit(...) here: You might end up getting different output results based on the system/user using your application! All of toLatin1(...), toAscii(...) and toUtf8(...) have a well defined output.

You're welcome ;-) Make sure you add "[Solved]" to your initial posts title to indicate that there is a solution inside.

bq. BTW: there is a difference you use “Resources” and “Resource”. If it is copy and paste from your source this might be the problem. have just mistyped... :) Mistake was, I've used "qrc:/Resources/404.html" and not ":/Resources/404.html" Thanks!

[solved] I answer to myself : the method dockWidgetArea() is in QMainWindow class : @QMainWindow::dockWidgetArea ( QDockWidget * dockwidget )@

Thanks... It's exactly what I've looking for. BR,

My mistake. I interpreted UTF-16 as UTF-8, using .constData()' instead of qPrintable(...)'. Everything's fine now, and thanks to all of you for your help.

I don't think there's one, but see http://developer.qt.nokia.com/doc/qt-4.8/threads-modules.html

The Button was chekable To this worke after pressing of pushButton we must call method QWidget::setStyleSheet("")

Of course it does work, because QString.h and qstring.h (and as well QSTRING.H or qStRiNg.H) are all the same file. On Unix/Linux these are different files. On the Mac the filesystem usually (default settings) is case-IN-sensitive either, as on Windows. The recommended way to include directives in C++ in general is @ #include <QString> @ i.e. using case (if used in the API docs) and without a trailing .h - this is expected to be portable across all platforms. If you do differently, you might run into troubles.

Me neither, hence the forum post. I thank you for your help anyway.

have tried this allready... doesn't help... looks like I must subclass QStatusBar and reimplement its paintEvent...
