# Qt Designer

In addition, the QFormBuilder class provides the possibility of constructing user interfaces from UI files at run-time.

Note: This documentation covers the tool Qt Designer and classes related to building graphical user interfaces for Qt Widgets. Qt Design Studio is a UI composition tool that covers all steps of UI design and implementation for Qt Quick user interfaces.

## Using the Module

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

### Building with CMake

Use the `find_package()` command to locate the needed module component in the `Qt6` package:

     find_package(Qt6 REQUIRED COMPONENTS Designer)
     target_link_libraries(mytarget PRIVATE Qt6::Designer)

For more details, see the Build with CMake overview.

### Building with qmake

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 += designer
