WebComponent support

WebComponent support in BDL 2.30 allows you to add any html-based component to your BDL application.

Support for WebComponent introduced with Genero BDL 2.30. GDC can embed a Component based on HTML / JavaScript™ / Flash and, via a small interface API, create a bridge between the component and 4GL. This allows you to add any html-based component to your 4GL application, such as a simple Image map which triggers a 4GL action when clicking on an area.

The GDC internal browser uses WebKit technology. If you want to use a plug-in for your WebComponent, you need to make sure that the corresponding plug-in is installed on the workstation where GDC runs.

Note:

The plug-in must be compatible with WebKit ; usually Netscape plug-ins (the technology used by Mozilla Firefox) are supported by WebKit.
If you want to use Flash inside GDC, you need to install either the Stand-Alone Flash player or the FireFox Plug-in. Having only an Internet Explorer (IE) plug-in is not sufficient, as IE plug-ins are based on a different underlying technology.
Plug-ins are similar to external libraries that are loaded at runtime. This implies that the plug-in must be binary compatible with GDC: if you run a 64-bit GDC, you need a 64-bit plug-in. This may be an issue if you run a Flash-based plug-in on Windows™, as today Adobe™ only provides a preview version of their Flash player on 64-bit Windows (code name "Square").
