Universal Rendering as standard

All front-ends (GDC, GAS, GMA, GMI) use now the GBC as rendering engine.

GBC as unique rendering engine

Genero version 3.20 introduced the Universal Rendering concept, which could be used as an option to display application forms on the GDC, GMA and GMI front-ends, using the GBC front-end as rendering engine.

Starting with version 4.00, the GBC front-end becomes the only available AUI tree rendering engine, to get an identical user interface on all type of front-ends (GDC, GMA, GMI, GAS).

The main new GUI feature of Genero 4.00 is Responsive Layout, implemented by the new V4 GBC. This feature available for all type of front-ends.

Feature changes

List of feature still supported, with slight change in behavior:
  • On desktop (GDC), program WINDOWs display now in the same window container. See Containers for program windows.
  • On a LAYOUT element (form/window), the MINWIDTH/MINHEIGHT attributes apply only to windows using the windowType="modal" style attribute.
  • With GDC 3.20 native mode, ERROR and MESSAGE notifications were displayed in the status bar. These are now rendered by default in a floating window by GBC.

  • Mobile platforms (GMA/GMI):
    • Mobile native rendering of listviews (AKA "full listviews", with two-column display and "embedded listviews"). Replacement for native listviews is TABLE + FLIPPED attribute, or SCROLLGRID.
