Qt Designer forms are processed at run-time to produce dynamically generated user interfaces. In order to generate a form at run-time, a resource file containing a UI file is needed.
A form loader object, provided by the QUiLoader class, is used to construct the user interface. This user interface can be retrieved from any QIODevice. For example, a QFile object can be used to obtain a form stored in a project's resources. The QUiLoader::load() function takes the user interface description contained in the file and constructs the form widget.
Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.
find_package() command to locate the needed module component in the
find_package(Qt6 REQUIRED COMPONENTS UiTools) target_link_libraries(mytarget PRIVATE Qt6::UiTools)
For more details, see the Build with CMake overview.
To configure the module for building with qmake, add the module as a value of the
QT variable in the project's .pro file:
QT += uitools
