Library that bundles ForkAwesome for use within Qt applications

Build instructions


The library depends on the following Qt modules (version 5.6 or higher): core, gui

The additional library for Qt Quick integration (currently only providing a QQuickImageProvider) depends on the following further Qt modules: quick

At build time qtutilities and c++utilities are required. This library is built in the same way as these libraries so checkout the c++utilities repository for detailed instructions.

To generate the header with icon definitions, Perl and the module YAML::XS (or YAML) are required. To use a specific Perl binary, one can set the CMake variable PERL.

Providing the font file

Of course the font file and icon definitions for ForkAwesome need to be supplied as well. Just download an archive from https://github.com/ForkAwesome/Fork-Awesome/releases and specify its path via the CMake variables FORK_AWESOME_FONT_FILE and FORK_AWESOME_ICON_DEFINITIONS, e.g. add -DFORK_AWESOME_FONT_FILE=/path/to/Fork-Awesome-1.2.0/fonts/forkawesome-webfont.woff2 and -DFORK_AWESOME_ICON_DEFINITIONS=/path/to/Fork-Awesome-1.2.0/src/icons/icons.yml to the CMake invocation. The font file will be built into the library and is hence only required at build time. If none of the variables are specified, the build system will attempt to download the files from GitHub.

The Web Open Font Format (the .woff/.woff2 file) might not be supported by the font renderer. Notably, Window's native font rendering which Qt uses by default does not support it. Then it makes sense to use the True Type Font instead. Alternatively, one can force the platform plugin to use FreeType2 (e.g. by setting QT_QPA_PLATFORM=windows:fontengine=freetype). Recent versions of FreeType2 even support Web Open Font Format 2 (the .woff2 file) but this requires FreeType2 to be configured with Brotli support.

Further remarks

As usual with CMake projects, it is possible to control whether to build as static or shared library via the BUILD_SHARED_LIBS variable. If you build qtforkawesome as part of another project and only want to affect qtforkawesome, you can also use the variable QT_FORK_AWESOME_BUILD_SHARED_LIBS.


The installation provides a CMake find module called qtforkawesome which provides the imported target qtforkawesome. A pkg-config file is provided as well. Once configured, the library is fairly simple to use:

#include <qtforkawesome/icon.h>
#include <qtforkawesome/renderer.h>
auto renderer = QtForkAwesome::Renderer();
renderer.pixmap(QtForkAwesome::Icon::Globe, QSize(64, 64), Qt::black);

There's also renderer.render(…) which takes a QPainter directly.

Icon engine

A QIconEnginePlugin is provided as well. When it is loaded one can create a QIcon using a file name with .fa extension, e.g.:

const auto icon = QIcon(QStringLiteral("qrcode:blue.fa"));

The color will be deduced from the applications default color palette unless it is specified explicitly like in the example above.

To link against the plugin statically, find the CMake module qtforkawesomeiconengine, link against the imported target qtforkawesomeiconengine and add Q_IMPORT_PLUGIN(ForkAwesomeIconEnginePlugin) to one of your source files.


A QQuickImageProvider is provided as well in form of the additional library qtquickforkawesome.

Then just include the header:

#include <qtquickforkawesome/imageprovider.h>

Create an instance and add it to your QQmlEngine:

engine->addImageProvider(QStringLiteral("fa"), new QtForkAwesome::QuickImageProvider(renderer));

And use it like this:

Image {
source: "image://fa/syncthing"


It is also possible to build the library as part of your project. Simply add it via add_subdirectory. Checkout the Syncthing Tray's project file for an example.
