@J.Hilk Your method is fine if you do not use QT Creator for style ... the best thing is to use it in GuiThread ... with these subclass I have a ToggledQLabel var ... so in mainwindow: if(ToggledQLabel){ ui->myToggledQLabel1->setstylesheet("ToggledQLabel{..............};");} else{ ui->myToggledQLabel1->setstylesheet("ToggledQLabel{......other style........};");} but I try to have I do not think that you are using a good approach, you have to use dynamic stylesheet properties, Using Dynamic properties with stylesheet You can add custom properties : you have to do things like that : simply I did not know it existed or their name .... the link on my abstracbutton addressed.

@J.Hilk sometime ago I was using Qt Creator 5.5.1. But when mrjj suggested using 5.7, I uninstalled 5.5.1 and installed 5.7. The program is built rand run using 5.7. Do you mean that I should uninstall 5.7 and install 5.8?

@ARASHz4 Well its a sample for "how to move the cursor" you must look at the doc and understand the code.... Then it will work :) Thank you to @J-Hilk for doing it for you :)

@matthew.kuiash Excellent, Your memory is good! Thank u very much.

By calling "prepareGeometryChange()" and then changing the fundamental parameters that are used in my overload of boundingRect()

@Paul-Colby thank you for answer it was work :)

@Massimiliano No, you do not drop it in your app directory! You just need to call it in a terminal window and pass the path to your binary as parameter. Please read the documentation: "The tool can be found in QTDIR/bin/windeployqt. It takes an .exe file or a directory that contains an .exe file as an argument, and scans the executable for dependencies."

Your first argument type may be wrong. It accepts qwidget type. You must be passing different type

@Chris-Kawa Thanks for this hint and this what i tried MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); ui->webView->load(QUrl("https://www.login.com")); // load page that have user name and password field QWebPage *page = ui->webView->page(); // get the current page manager = page->networkAccessManager(); // get the access manager from this page } MainWindow::~MainWindow() { delete ui; } // get button void MainWindow::on_pushButton_clicked() { reply = manager->get(QNetworkRequest(QUrl("https://www.login.com"))); // make get now after login connect(reply, SIGNAL(readyRead()),this,SLOT(readyRead())); connect(reply, SIGNAL(finished()),this, SLOT(finish())); } void MainWindow::readyRead() { QString str = QString::fromUtf8(reply->readAll()).trimmed(); // read the data ui->plainTextEdit->appendPlainText(str); } but i get the data of the first page without the login i want to get the page content after login please give me any hint or what i should do Thanks

You have to many backslashes, remove the ones that are on leaf lines. Then as @mostefa suggested, try to build a default application and if that succeed, try again using QString somewhere in it. If these two succeed, then there's something fishy with your code.

@mrjj Thank you. That could do the job.

Please read my previous edited post. I changed the name of Cal.exe file.

There are 4 pointers in that class: textEdit, customerList, paragraphsList and viewMenu. All of them need to be initialized somewhere. The first one is initialized in the initialization list of the class constructor as you mentioned. Using initialization list doesn't require you to init the member via a parameter. It can be initialized from any value, in this case it's a new statement. For example: class Foo { public: Foo() : bar(42) {} //initializing bar via value Foo(int param) : bar(param) {} //initializing bar via param Foo() { initBar(); } //initializing bar via member function private: void initBar() { bar = 42; } int bar; }; The example uses the first type of initialization for textEdit. All the other pointer members are initialized in the MainWindow::createDockWindows() which is called from the constructor's body. It's the third type of initialization from the example above.

@Panoss Np. Thats why i lurk around here :)

Calling qApp->quit() before exec() won't have any effect since the event loop isn't even started.

@Waxta well remove all qt. Install the 5.8 one. Maybe the Qt plugin for visual studio. It should just work. https://download.qt.io/official_releases/qt/5.8/5.8.0/qt-opensource-windows-x86-msvc2015_64-5.8.0.exe.mirrorlist

QVector for sequential access. QHash/QSet (basically the same thing) for non-sequential access but you need to provide a hashing function.

@goktug1415 When installing the Qt mingw packet then mingw is included. Not in the Creator download. Just try a new Defualt GUI project via the new project menu. If it runs. all is good :)
