Overview

Qt is a cross-platform application framework.

Go (often referred to as golang) is a free and open source programming language created at Google.

This binding aims to make it as simple as possible to write applications for all operating systems supported by Qt in Go.

The project is pretty much a WIP and not recommended to be used in production yet.

However it should already contain everything you need to build fully featured Qt applications in Go.

Installation

Full or stub installation?

The full installation requires at least 8gb free ram and takes 20 min.

The stub installation requires only 2gb free ram and takes 10 min.

The only difference between those two version is, that you won't be able to use go run/build to build your applications if you choose to install the stub version. You are therefore limited to the use of qtdeploy to build your application.

To build the stub version export QT_STUB=true system wide and proceed with the installation as usual.

Environmental variables

If you define environmental variables during the installation export them system wide, as they are needed not only during the installation but also later.

Add the environmental variables into your $HOME/.bash_profile or $HOME/.profile on macOS or Linux.

Or if you are on Windows simply use the advanced system settings.

Docker Images

You can also use Docker images from hub.docker.

To cross compile to Windows, Linux and Android.

You will still need to install the desktop version for your host system first!

But if you want to use the images only for CI, then you probably don't need to install the binding or Qt on the host. Simply installing and using qtdeploy should be enough.

Command line debugging

You can export QT_DEBUG=true before "qtdeploying" your application to enable printing of the current function name at runtime.

Speedup your development

Instead of using qtdeploy during development, you might want to use qtrcc, qtmoc, qtminimal manually with go build/run -tags=minimal ...

In general qtminimal should always be called after the use of the optional use of qtrcc and qtmoc.

qtrcc is used to bundle your project/qml folder so you can access the files within by using the qrc prefix, like this qrc:///qml/somefile from various Qt functions.

qtmoc is used to subclass core.QObject based classes and to add your own signals/slots/properties as shown in some examples.

qtminimal is used to create a small subset of the binding tailored to your code to reduce the binary size. (Use the -tags=minimal flag to make use of it)

If you use the STUB version, you are forced to use qtminimal otherwise it's optional like qtrcc and qtmoc.
