CrossWindow

Documentation | Demos | Other Libraries

Cross Window is a cross platform system abstraction library for managing windows and performing OS tasks. It's designed to be easy to integrate, intuitive, and support everything you might need for your apps.

Features

• 🌟 Simple Window, File Dialog, and Message Dialog Creation.

• ⌨️ 🖱️ 👆 🎮 Basic Input (Keyboard, Mouse, Touch, and Gamepad).

• 👻 Platform specific features (Mac Transparency, Mobile Accelerometer, etc.).

• 💊 Unit Tests + Test Coverage (Appveyor for Windows, CircleCI for Android / MacOS / iOS, [Travis][travis-url] for Linux/Noop).

Supported Platforms

• 🖼️ Windows - Win32

• 🍎 Mac - Cocoa

• 📱 iOS - UIKit

• 🐧 Linux - XCB or XLib

• 🤖 Android (In Progress)

• 🌐 WebAssembly - Emscripten

• ❌ Noop (Headless)

Installation

First add the repo as a submodule in your dependencies folder such as external/:

# ⤵️ Add your dependency as a git submodule:
git submodule add https://github.com/alaingalvan/crosswindow.git external/crosswindow

Then in your CMakeLists.txt file, include the following:

# ⤵️ Add to your CMake Project:
add_subdirectory(external/crosswindow)

# ❎ When creating your executable use CrossWindow's abstraction function:
xwin_add_executable(
    # Target
    ${PROJECT_NAME}
    # Source Files (make sure to surround in quotations so CMake treats it as a list)
    "${SOURCE_FILES}"
)

# 🔗 Link CrossWindow to your project:
target_link_libraries(
    ${PROJECT_NAME}
    CrossWindow
)

Fill out the rest of your CMakeLists.txt file with any other source files and dependencies you may have, then in your project root:

# 🖼️ To build your Visual Studio solution on Windows x64
cmake -B build -A x64

# 🍎 To build your XCode project On Mac OS for Mac OS
cmake -B build -G Xcode

# 📱 To build your XCode project on Mac OS for iOS / iPad OS / tvOS / watchOS
cmake -B build -G Xcode -DCMAKE_SYSTEM_NAME=iOS

# 🐧 To build your .make file on Linux
cmake -B build

# 🔨 Build on any platform:
cmake -B build --build

For WebAssembly you'll need to have Emscripten installed. Assuming you have the SDK installed, do the following to build a WebAssembly project:

# 🌐 For WebAssembly Projects
mkdir webassembly
cd webassembly
cmake .. -DXWIN_OS=WASM -DCMAKE_TOOLCHAIN_FILE="$EMSDK/emscripten/1.38.1/cmake/Modules/Platform/Emscripten.cmake" -DCMAKE_BUILD_TYPE=Release

# Run emconfigure with the normal configure command as an argument.
$EMSDK/emscripten/emconfigure ./configure

# Run emmake with the normal make to generate linked LLVM bitcode.
$EMSDK/emscripten/emmake make

# Compile the linked bitcode generated by make (project.bc) to JavaScript.
#  'project.bc' should be replaced with the make output for your project (e.g. 'yourproject.so')
$EMSDK/emscripten/emcc project.bc -o project.js

For more information visit the Emscripten Docs on CMake.

For Android Studio you'll need to make a project, then edit your build.gradle file.

// 🤖 To build your Android Studio project
android {
    ...
    externalNativeBuild {
        cmake {
            ...
            // Use the following syntax when passing arguments to variables:
            // arguments "-DVAR_NAME=ARGUMENT".
            arguments "-DXWIN_OS=ANDROID",
            // The following line passes 'rtti' and 'exceptions' to 'ANDROID_CPP_FEATURES'.
            "-DANDROID_CPP_FEATURES=rtti exceptions"
        }
    }
  buildTypes {...}

  // Use this block to link Gradle to your CMake build script.
  externalNativeBuild {
    cmake {...}
  }
}

for more information visit Android Studio's docs on CMake.

Usage

Then create a main delegate function void xmain(int argc, const char** argv) in a .cpp file in your project (for example "XMain.cpp") where you'll put your application logic:

#include "CrossWindow/CrossWindow.h"

void xmain(int argc, const char** argv)
{
    // 🖼️ Create Window Description
    xwin::WindowDesc windowDesc;
    windowDesc.name = "Test";
    windowDesc.title = "My Title";
    windowDesc.visible = true;
    windowDesc.width = 1280;
    windowDesc.height = 720;

    bool closed = false;

    // 🌟 Initialize
    xwin::Window window;
    xwin::EventQueue eventQueue;

    if (!window.create(windowDesc, eventQueue))
    { return; }

    // 🏁 Engine loop
    bool isRunning = true;

    while (isRunning)
    {
        // ♻️ Update the event queue
        eventQueue.update();

        // 🎈 Iterate through that queue:
        while (!eventQueue.empty())
        {
            const xwin::Event& event = eventQueue.front();

            if (event.type == xwin::EventType::MouseInput)
            {
                const xwin::MouseInputData mouse = event.data.mouseInput;
            }
            if (event.type == xwin::EventType::Close)
            {
                window.close();
                isRunning = false;
            }

            eventQueue.pop();
        }
    }
}

This xmain function will be called from a platform specific main function that will be included in your main project by CMake. If you ever need to access something from the platform specific main function for whatever reason, you'll find it in xwin::getXWinState().

Development

Be sure to have CMake Installed.

CMake Options	Description
XWIN_TESTS	Whether or not unit tests are enabled. Defaults to OFF, Can be ON or OFF.
XWIN_API	The OS API to use for window generation, defaults to AUTO, can be can be NOOP, WIN32, COCOA, UIKIT, XCB , ANDROID, or WASM.
XWIN_OS	Optional - What Operating System to build for, functions as a quicker way of setting target platforms. Defaults to AUTO, can be NOOP, WINDOWS, MACOS, LINUX, ANDROID, IOS, WASM. If your platform supports multiple apis, the final api will be automatically set to CrossWindow defaults ( WIN32 on Windows, XCB on Linux ). If XWIN_API is set this option is ignored.

First install Git, then open any terminal in any folder and type:

# 🐑 Clone the repo
git clone https://github.com/alaingalvan/crosswindow.git --recurse-submodules

# 💿 go inside the folder
cd crosswindow

# 👯 If you forget to `recurse-submodules` you can always run:
git submodule update --init

From there we'll need to set up our build files. Be sure to have the following installed:

• CMake

• An IDE such as Visual Studio, XCode, or a compiler such as GCC.

Then type the following in your terminal from the repo folder:

# 🖼️ To build your Visual Studio solution on Windows x64
cmake -B build -A x64 -DXWIN_TESTS=ON

# 🍎 To build your XCode project on Mac OS
cmake -B build -G Xcode -DXWIN_TESTS=ON

# 🐧 To build your .make file on Linux
cmake -B build -DXWIN_TESTS=ON

# 🔨 Build on any platform:
cmake -B build --build

Whenever you add new files to the project, run cmake .. from your solution/project folder /build/, and if you edit the CMakeLists.txt file be sure to delete the generated files and run Cmake again.
