Description
This project provides bindings that allow the QT Gui toolkit to be used from the Ruby Programming language. Overall it is a repackaging of a subset of the KDE bindings ruby and smoke systems into a format that lends itself well to packaging into a Ruby gem.

Just install the gem and have platform-independent GUI that just works on Mac, Windows, and Linux. -

Gladiator (Glimmer Editor)
Gladiator (short for Glimmer Editor) is a Glimmer DSL for SWT sample project under on-going development that demonstrates how to build a text editor in Ruby using Glimmer DSL for SWT (JRuby Desktop Development GUI Library). It is not intended to be a full-fledged editor by any means, yet mostly a fun educational exercise in using Glimmer. Gladiator is also a personal tool for shaping an editor exactly the way I like, with all the keyboard shortcuts I prefer. I leave building truly professional text editors to software tooling experts who would hopefully use Glimmer one day. Otherwise, I have been happily using Gladiator to develop all my open-source projects since May of 2020. -

README
qtbindings - Ruby bindings to QT
Warning: This project is no longer maintained. It only supports Qt4 which the latest linux distributions no longer include in their package repos. No future releases or changes are planned. If you would like to take over, please fork, and make the changes to support Qt5/Qt6. This will be really difficult as the Smoke libraries used in this project do not work well with C++11+. Its been a fun 10 years maintaining this for the Ruby community, but at this point I would recommend using Python if you want to create a modern desktop application using Qt. I'm personally switching to developing web apps using Vue.
Note: The current windows gem (since 4.8.6.4) only works with Ruby 2.4 and Ruby 2.5. To use Ruby 2.0 to Ruby 2.3 please install version 4.8.6.3
This project provides bindings that allow the QT Gui toolkit to be used from the Ruby Programming language. Overall it is a repackaging of a subset of the KDE bindings ruby and smoke systems into a format that lends itself well to packaging into a Ruby gem.
Goals
- To make it easy to install a Qt binding for Ruby on all platforms using RubyGems
- To maintain an up-to-date binary gem for Windows that is bundled with the latest version of Qt 4
- To reduce the scope and maintenance of the bindings to only bind to the libraries provided by the Qt SDK.
- To increase compatibility with non-linux platforms
Note: Qt 4.8.7 and 5.X is currently NOT supported.
For Ruby 1.9.3 you should use version 4.8.5.2.
For Ruby 1.8.x you can try installing version 4.8.3.0, however upgrading Ruby is highly recommended.
Usage Notes
Ruby threading is now fully supported out of the box. All GUI access however must be done inside the main thread. To support updating the GUI using other threads, use the following function provided in Qt4.rb:
Qt.execute_in_main_thread do # block the main thread
# GUI code which executes and then allows the main thread to execute
end
Qt.execute_in_main_thread(false) do # don't block the main thread
# GUI code which executes in parallel with the main thread
end
To use Qt plugins (Reading jpgs, etc) on Windows, you should add this line after creating your Qt::Application.
Qt::Application.instance.addLibraryPath(Qt::PLUGIN_PATH)
Tested Environments
Mac OSX 10.13.6 (High Sierra)
XCode 5 (clang)
Brew - QT 4.8.6
CMake 3.10.2
Ruby 2.6.5 - Must be compiled with clang (rvm install --with-gcc=clang)
Windows 7 SP1
QT SDK 4.8.6-1
CMake 3.6.3
Ruby 2.5.7 installed from rubyinstaller.org
Ubuntu Linux 16.04 QT SDK 4.8.6 Cmake 2.8.5
Compiling
Compiling qtbindings requires the following prerequisites:
- Ruby (Ruby must be compiled with --enable-shared on all platforms and with --with-gcc=clang on OSX)
On Windows use the latest from RubyInstaller
You'll need both the 32bit and 64bit installers to make the fat binary gem - CMake 3.6.x
- On Windows get OpenSSL 1.0.2 x64 (not Light)
Install with all defaults to C:\OpenSSL-Win64 - QT 4.8.6 (mingw version for Windows)
On Windows install to C:\Qt\4.8.6-Ruby24 (when installing specify the mingw inside the 32bit DevKit)
On Windows install a second copy to C:\Qt\4.8.6-64-Ruby24 (when installing specify the mingw inside the 64bit DevKit)
Install Jom to C:\Qt\4.8.6-64-Ruby24 (or anywhere in your path) - gcc 4.x, 5.x, or 6.x (or clang for OSX 10.9)
On Windows gcc 4.x is included in the DevKit
Note for OSX 10.9. The default compiler has changed from gcc to clang. All libraries need to be compiled with clang or you will get segfaults. This includes ruby, qt, and qtbindings. *** rvm does not compile with clang by default. You must add --with-gcc=clang when installing a version of ruby ***
Additionally: all of the operating system prequisites for compiling, window system development, opengl, etc must be installed.
Rakefile
Perform the following steps to build the gem on Unix or Mac:
rake VERSION=4.8.x.y gem
Where the x is the subversion of QT and y is the patch level of qtbindings
Perform the following steps to build the gem on Windows:
- cd vendor
- Edit BuildWindowsGems.bat to ensure all paths are correct
- Run: BuildWindowsGems.bat
Note: The gem is built two times to create two FAT binaries which will work on Ruby 2.4 and higher (x64/x86).
After building the gem, verify the examples work by running:
rake examples
Operating Systems Notes:
Debian Linux
- The following should get you the packages you need:
sudo aptitude install build-essential bison openssl libreadline5 \
libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim \
libsqlite3-0 libsqlite3-dev sqlite3 \
libxml2-dev git-core subversion autoconf xorg-dev libgl1-mesa-dev \
libglu1-mesa-dev ruby-dev libqt4-dev
Fedora Linux
You will also need these packages:
sudo yum install qtwebkit-devel qtwebkit
Mac OSX Snow Leopard
- XCode
- Brew (http://mxcl.github.com/homebrew/)
Install qt withbrew install qt
Windows - Note: Only necessary for debugging (binary gem available)
Qt should be rebuilt using Devkit before building.
- Run vendor\PatchQt4.8.6Ruby24.bat
- Copy vendor\BuildQt4Win32Ruby24.bat to C:\Qt\4.8.6-Ruby24 and run it
- Copy vendor\BuildQt4Win64Ruby24.bat to C:\Qt\4.8.6-64-Ruby24 and run it
Install
On linux/MacOSX you must make sure you have all the necessary prerequisites installed or the compile will fail.
gem install qtbindings
This should always work flawlessly on Windows because everything is nicely packaged into a binary gem. However, the gem is very large ~90MB, so please be patient while gem downloads the file.
