Normalerweise ist es ausreichend, wenn Sie die Anweisungen des Herstellers kurz überprüfen und Sie werden mit Sicherheit keine weiteren Fragen mehr … The missing one is how can i create QDialog using QT Creator (. QGroupBox(Dialog). Create a button to open the modal and a Icon or a expression inside the modal to close it. Regulate the Qt Event Queue 332. exec() in the exported function from the qt gui dll. Then we will see how to build dialogs using Qt Designer, Qt's visual design tool. I have installed Qt and Qt for VS plugin. Everything works fine, UI applications compile and run that's ok, but connecting signals and slots doesn't. I have Q_OBJECT in my class and for connecting I am using this code in constructor: connect(ui.mainTableView, SIGNAL(activated(const QModelIndex &)), this, SLOT(showDetail(const QModelIndex &))); I choosed the Qt extension for VS since I wasn't able to run remote debug (Win10 <-> Win10) with Qt Creator. After some fiddling around with the Qt VS Tools, the remote debug seems to work for me. However, I haven't found a way how to connect a signal comming from a GUI element to a defined slot function - the Qt creator has a few-click See full list on doc.qt.io Signal and Slot Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks. In GUI programming, when we change one widget, we often want another widget to be notified.

Personally. Qt is by far the best lib for graphics (GUI) prog and is transferable to any C++ IDE. Learning curve is a bit steep, but it is much more than just a GUI toolkit.

I have Q_OBJECT in my class and for connecting I am using this code in constructor: connect(ui.mainTableView, SIGNAL(activated(const QModelIndex &)), this, SLOT(showDetail(const QModelIndex &))); In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal.

Porém eu necessito saber quando o processo termina, então criei um connect com um signal já existente no QProces" de nome finished, este que tem como SLOT criado por mim, porém este signal nunca é chamado gostaria de saber se há algo errado em meu(que já revisei várias vezes), ou se não é possível utilizar este signal em um QThread.

Let's try making a trivial application that has a single window that shows a QLabel and a QLineEdit. To do this follow these simple steps: Start up Qt Creator: Go to File — New File or Project menu entry Choose Qt Gui Application and choose a name for it: Enter a project name, "qt-tutorial-01", say. Select one or more versions of Qt to target.

Qt's widgets have many pre-defined slots, but it is common practice to subclass widgets and add your own slots so that you can handle the signals that you are interested in. The signals and slots mechanism is type safe: The signature of a signal must match the signature of the receiving slot.
