Hi, ~TND5! Welcome to Qt Developer Network! As DerMan explained - any Qt top-level widgets without parents displays with QFrame. So if you run this code: @ QWidget a; // a - without parent a.setGeometry(10,10,300,200); // x = 10, y = 10, width = 300, height = 200 a.show(); // show it @ It will show new window which will contain all that a contains. But if you run this code in MainWindow for e.g: @ QWidget a(this); // a - with parent a.show(); // show it @ It will display a in this widget.

I revised the line to : glPolygonMode(GL_BACK, GL_LINE); the problem still exists, HHHOoooWWwwever, glPolygonMode(GL_FRONT, GL_LINE); sloved the problem and the two items come out to be as expected. Why?

I have resolved it, client missed CA certificate so: @Socket->addCaCertificates("C:/SOURCE/Project/Qt/server.csr");@ added to client fixed my problem.

@Lukas: Thank you for the links. I'm studying multithreading only to know its possibilities, and those links are just what I needed :-)

Well then a Hash is definetly the right thing and an encryption is definetly the wrong thing to use. Further one shouldn't make up own security/authorization protocols when not proficient in it. Your scheme looks like it's vulnerable to replay attacks (due to the determinism in "Server increments question"). Make your application work with the standard mechanisms in the field: https://en.wikipedia.org/wiki/Cryptographic_nonce https://en.wikipedia.org/wiki/Cryptographic_salt

bq. What happens when you don’t use the public slots notation, but Q_SLOTS? does qmake run successfully? --Thank you.The code after replacing public slots notation to Q_SLOTS compiled and run successfully.That is because of includes of QWT in the project I guess with high likelihood and having a reason. Solved.

tnx

Your a life saver Zlatomir, thanks.

I don't understand your question, may be you want to use "itemAt()":http://qt-project.org/doc/qt-4.8/qgraphicsscene.html#itemAt or "itemAt()":http://qt-project.org/doc/qt-4.8/qgraphicsscene.html#itemAt-3 at "QGraphicsScene::MousePressEvent":http://qt-project.org/doc/qt-4.8/qgraphicsscene.html#mousePressEvent. Note that you must pass "scenePos()":http://qt-project.org/doc/qt-4.8/qgraphicsscenemouseevent.html#scenePos to itemAt() as parameter.

Hi, Eric, welcome to Devnet! Please be sure to wrap your code snippets in @ tags for formatting. Also, please open new threads for additional topics/questions. Thanks, and welcome again!

Well have a list of points variable in your scene most likely. @QList<QPoint> clicked_points_;@ and in your QGraphicsScene derive "mousePressEvent":http://qt-project.org/doc/qt-4.8/qgraphicsscene.html#mousePressEvent in it check the functions argument for button() to see which button is pressed If left button append the "button down in screen pos":http://qt-project.org/doc/qt-4.8/qgraphicsscenemouseevent.html#buttonDownScreenPos to clicked_points_ or if right button display clicked_points_ values and clear list after that if needed if you want to "return on right click" have a signal to emit clicked_points_, catch that in a slot and you'd be done.

Hi, Here is how I resolved the problem: @ QRegExp [removed]"^CREATE.(TABLE |TABLE IF NOT EXISTS |VIEW |DATABASE |PROCEDURE |FUNCTION |TRIGGER |EVENT ).[A-Za-z_\\d%]*\.{0,1}[A-Za-z_\\d%]*{0,1}"); expression.indexIn(line); QRegExp expression2("[A-Za-z_\\d%]*\.[A-Za-z_\\d%]*"); expression2.indexIn(line); symbolName = expression2.capturedTexts().at(0); if (symbolName.isEmpty()) { QRegExp expression3("[A-Za-z_\\d%]*"); expression3.indexIn(line); symbolName = expression3.capturedTexts().at(0); } symbolName = symbolName.replace("`", ""); symbolsLineNumber.insert(symbolName, counter); listSymbols->addItem(new QListWidgetItem(QIcon(icon), symbolName)); @

I haven't tried it myself, but you might be able to run "Doxygen":http://www.stack.nl/~dimitri/doxygen/ against the Qt source tree to generate PDF docs. Of course, there may be something much easier, too.

Never mind - I was being dim, my view was going out of scope.

Sorry for so dealyed reply , actually I was busy :P . Anyways the error which I am getting is :QNetworkReply::SslHandshakeFailedError which has error code as 6 .

"Here":http://doc-snapshot.qt-project.org/4.8/sharedlibrary.html.

I would rather write (don't know whether it works though): QRegExp regx("&lt;iframe .*src=\"(.+?)(\".*&gt;&lt;/iframe>)"); Note the + instead of your *. + stands for at least one character and maybe more, whilst * stands for zero or one character. [quote author="ThaRez" date="1340956318"]I also tried: @QRegExp regx("<iframe .src="(.?)(".></iframe>)"); QRegExp regx("<iframe .src="(.?)(".></iframe>)");@ But neither matched anything... Any further suggestions? Thanks! -RS [/quote]
