If the CONFIG variable contains the qt value, qmake's support for Qt applications is enabled. This makes it possible to fine-tune which of the Qt modules are used by your application. This is achieved with the QT variable which can be used to declare the required extension modules. For ex...
So here is the solution: I forgot to declare the class an export by using the QT define generated when the project first gets made. The class line of the first file (Interface) should read: class BUILDERCORE_EXPORT IBuilderMode : QObject, BuilderObject ...
When this code is run, an error will display in the console that refers explicitly to the line number where the string value was set, and stating Error: Cannot assign QString to int, making the code easier to troubleshoot. If a value with the wrong type is assigned to a variable of ...
This macro can be used to declare variable that should be constructed at compile-time, or an inline function that can be computed at compile-time. It expands to "constexpr" if your compiler supports that C++11 keyword, or to nothing otherwise. ...
Because QVariant is part of the Qt Core module, it cannot provide conversion functions to data types defined in Qt GUI, such as QColor, QImage, and QPixmap. In other words, there is no toColor() function. Instead, you can use the QVariant::value() or the qvariant_cast() template ...
