| Genero Web Client Basics / How the GAS / GWC uses Web Technologies to deliver an application | |
The Genero Web Client is able to interact with the browser using the browser framework (HTTP, HTML Forms, and so on) named Page Mode. The Genero Web Client provides the browser a complete xHTML page describing the current 4GL application state. JavaScript™ can be used on the browser side for any purpose such as a calendar pop-up or input control as picture, format, and so on.
GWC is also able to interact with the browser using a JavaScript framework. In this case, the GWC provides to this JavaScript framework incremental HTML modifications (according to the template and template snippets) and some dialog structures directly issued from the DVM. The JavaScript framework can then have a more 4GL-like behavior.
We provide a template/snippets customization set with a complete JavaScript framework. You could customize widgets dynamic behavior by modifying JavaScript hooks, however main modifications can (and should) be done mostly on snippets and thru CSS.
