General and Desktop

Neither. The concept of 'Mouse Shortcuts' is best handled at the Desktop and KApplication layers, not down inside Qt.

Ah, I see - I hadn't considered these more complicated scenarios. Thanks for the INCLUDEPATH tip, too - I think this sounds like the best fit for my programming style.

It seems that it was a Microsoft compiler problem. I added a typedef for the list and implemented the getter and setter directly in the header and now it is working.

Hello ChrisW67 and Lukas First, I changed to: @ QString program = "../helper-functions/Perl/DiscoverNodes"; QProcess *myprocess = new QProcess(this); qRegisterMetaType<QTextCharFormat>("QTextCharFormat"); qRegisterMetaType<QTextCursor>("QTextCursor"); //myprocess->startDetached(program.toStdString().c_str()); myprocess->start(program);@ Next, about segfault: I did a core dump, and here is the info: #0 0x00007f4eb7f04525 in QTextLayout::createLine() () from /usr/lib/x86_64-linux-gnu/libQtGui.so.4 #1 0x00007f4eb7f3976a in ??

[quote author="Krzysztof Kawa" date="1357229504"]You need to layout the label in the parent widget: @ void MyWidget::AnimatedLogo(QString logotype) { QMovie *MyLogoMovie = new QMovie(logotype); MyLogoLabel = new QLabel(); MyLogoLabel ->setMovie(MyLogoMovie); MyLogoMovie->start(); MyLogoLabel->setAlignment(Qt::AlignCenter); // MyLogoLabel >show(); //this is redundant QVBoxLayout* layout = new QVBoxLayout(); layout->addWidget(MyLogoLabel); setLayout(layout); } @ Btw. identifier names starting with capital letter are usually used for class names not variables.[/quote] THANK YOU! bq. Btw. identifier names starting with capital letter are usually used for class names not variables. Thanks for the tip.

Well according to the doc cannonicalPath() indeed returns empty string if the file doesn't exist but you should be fine with absolutePath()

Hi Leon I mean that : If user enter time then youTube video should be played for that time interval only. Thanks & Regards priya_sipl

Try something like this: @ QWidget widget; QLineEdit* lineEdit = new QLineEdit; QLabel* label = new QLabel; QVBoxLayout* layout = new QVBoxLayout; //replace these with your for loop layout->addWidget( lineEdit ); layout->addWidget( label ); // you can use this at the end of the widgets (after the for loop) layout->addStretch(); widget.setLayout( layout ); // important @

QTcpSocket will always buffer your data for asynchronous transfer. You can set the amount of data buffered while reading using "QAbstractSocket::setReadBufferSize()":http://doc.qt.digia.com/qt/qabstractsocket.html#setReadBufferSize. Technically QTcpSocket has one abstraction layer less than QDataStream, so it may provide better performance. However, I seriously doubt that there is any difference in pratice, because usually the network bandwidth will be the limiting factor, not the processing power. So go for the most convenient solution, regardless wheter you use QDataStream, QTcpSocket or low level read() and write(), as you will almost always provide data at a higher rate your network can handle.
