Qt Virtual Keyboard

The Qt Virtual Keyboard project provides an input framework and reference keyboard frontend for Qt 6 on Linux Desktop/X11, Windows Desktop, and Boot2Qt targets.

The input framework makes it easy to write custom input methods or to integrate 3rd party input engines. The input methods can be implemented in C++ or QML.

Using the Module

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.

Building with CMake

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

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

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 += virtualkeyboard
