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