Awesomium running inside O$ 4.3.X

Introduction

The following project is a Tech-Demo demonstrating the usage of Awesomium as an Omnis Studio External to display HTML5 content and to invoke Omnis Studio code from JavaScript and vice versa.

Awesomium is a commercial product for commercial apps, which exposes Chromium through an easy to use C++ API.

As it is currently unclear if the source/header/bin files from Omnis Studio and/or Awesomium can freely be distributed, we removed them from the initial release.

Any feedback regarding mistakes, possible errors and improvements is welcome.

To experience the Tech-Demo download the repo and follow the instructions.

Requirements

• Win 7
• O$ 4.3.X Non-Unicode
• Omnis Externals SDK for O$ 4.3.1
• Awesomium 1.7.X SDK with C++ examples
• Visual Studio C++ 2008 (Express)

Installation

• Install Awesomium and copy the following files into the specified project directory:

  • AWESOMIUM\build\bin to deploy\bin\ext\web\browser\system
  • AWESOMIUM\build\bin\awesomium.dll to deploy\bin\xcomp
  • AWESOMIUM\build\lib\awesomium.lib to include\lib
  • AWESOMIUM\include\Awesomium to include\awesomium
  • C:\Users\Public\Documents\Awesomium SDK Samples\1.7.4.X\Awesomium\BuildSamples\common\js_delegate.h to src\js_delegate.h#
  • C:\Users\Public\Documents\Awesomium SDK Samples\1.7.4.X\Awesomium\BuildSamples\common\method_dispatcher.h to src\method_dispatcher.h
  • C:\Users\Public\Documents\Awesomium SDK Samples\1.7.4.X\Awesomium\BuildSamples\common\method_dispatcher.cpp to src\method_dispatcher.cpp

• Install the Omnis External SDK and copy the following files into the specified project directory:

  • OMNISDK\LIBS\omnis.lib to include\lib
  • OMNISDK\COMPLIB to include\omnis

• Copy the contents of deploy\bin\xcomp into OMNIS431INSTALLDIR\xcomp

• Modify the files resources\testdebug.bat and testtrelease.bat to match your local installation

• Start Visual Studio 2008 C++ and open the proj\webLib.vcproj file

Building the external

• Build the C++ Project inside Visual Studio and make sure no errors occur during the build process
• After a successful build run the C++ program in Debug Mode
• When asked for an executable, select your omnis.exe and the path to you're lbs\demo.lbs from this project as an commandline parameter
• When the lbs\demo.lbs is launched for the first time a modification inside the StartupTask is necessary. The variable iBasePath has to match the path of the root folder of this project

Samples

The demo.lbs contains the following examples:

• Websites

  • html5test.com
  • google.com
  • media.tojicode.com/q3bsp/ (WebGL Demo)

• Event Demo
  • Demonstrates how to read properties in JavaScript from Omnis Studio and how to use these inside JavaScript
  • Shows how to send events from JavaScript to Omnis Studio (show Omnis OK message, Close current window from JavaScript)

• Ace9 Code Editor inside Omnis Studio
  • Demonstrates how to wrap a HTML component and how a two-way interaction is possible (setData & getData)

• Download
  • Download of a pdf File with a callback in Omnis Studio to return the path, where the file should be saved to.

Notes

• Lacks documentation
• Ugly C++ char conversion
• Windows only
• Every instance of the component creates its own process, which could be changed so that they every WebView is a child of one master WebView, which would save cpu & memory
• It should be possible to us the JsClient inside Omnis and communicate between Omnis Fat-Client and Omnis JsClient

Thanks

• Thanks to David McKeone for the NVObjTemplate (https://github.com/dmckeone/NVObjTemplate) he published on github
