ICPP-Qt - Writing GUI script with C++

An icpp module of the cross-platform GUI toolkit Qt.

• Writing GUI script with C++ becomes so easy;
• Supporting macOS/Linux/Windows;
• Packed with Qt6.9.0 (6.0.4 for Intel macOS/Linux);

C:\vpand>icpp qt
Module Qt6(v1.0.0) usage: icpp qt -- script.cc [argv...]

Follow the one-by-one step to build your own version of icpp-qt module.

Clone

Clone the qt main repository:

mkdir build
git clone https://code.qt.io/qt/qt5.git build/qt6
cd build/qt6

Clone the submodule repositories:

Unix

ARM Chip on macOS/Linux:

git switch 6.9
perl init-repository --module-subset=qtbase,qtshadertools,qtdeclarative,qthttpserver

Intel Chip on macOS/Linux:

git switch 6.0
perl init-repository --module-subset=qtbase,qtshadertools,qtsvg,qtdeclarative

Windows

git switch 6.9
.\init-repository.bat --module-subset=qtbase,qtshadertools,qtdeclarative,qthttpserver

Build

Set the current working directory as ICPP-QT/build:

cd ..

macOS

Building on macOS:

./qt6/configure -no-framework -prefix $PWD/install
cmake --build . --parallel 8
cmake --install .

Linux

Building on linux:

sudo apt-get install libx11-*
sudo apt-get install libx11*
sudo apt-get install libxcb-*
sudo apt-get install libxcb*
sudo apt-get install libxkbcommon-dev
sudo apt-get install libxkbcommon-x11-dev
sudo apt-get install libgl-dev libegl-dev libfontconfig1-dev libinput-dev
./qt6/configure -xcb -prefix $PWD/install
cmake --build . --parallel 8
cmake --install .

Linking the fonts:

# build/install/lib
ln -s ../../../fonts .

Windows

Make sure to open the correct command prompt (e.g. 'x64 Native Tools Command Prompt for VS 2022') which properly sets up the needed environment variables. Also make sure that Ninja can be found (by adding the path to ninja,exe to your PATH env var)

Building on windows:

.\qt6\configure.bat -prefix %cd%/install
cmake --build .
cmake --install .

Post Build

If you switched to another qt version, you should copy the exist icpp module configuration qt-*.json to a new file, and modify the binary-libs list which can be generated as follows:

icpp post-build.cc

Pack

Pack an icpp module(e.g.: qt-osx.json):

imod --create=./icpp-x.json

Install

Install the icpp-qt module(e.g.: qt-osx-arm64.icpp):

imod --install=./qt-x-x.icpp

Test

Don't miss the "--", it's important to make the qt related script running correctly. The following command arguments mean: run the qt module with the script file argument. The script will be running under the control of the qt module.

Run a qt related icpp script:

icpp qt -- test/helloworld.cc
