Hi Tarek,
Studio Developer comes with a brand new user interface designer for both GUI windows and Block Mode screens.
The UI Designer can be used with or without Rapide.
Apart from the support for Rapide described below, the new UI designer provides many enhancements to the way that you design UIs in Gen. These are described on the Studio Developer web site under UI Designer and Screen Designer and include enhancements like undo/redo, manipulate co-ordinates using arrow keys for fine adjustment or type in precise values, design the layout before needing to bind controls to specific views and more.
If you are using Rapide then all of the extended capabilities of Rapide are integrated in the UI Designer without needing to use a separate plug-in like the old toolset. This includes designing the additional types of controls supported by Rapide like tree views, tab controls, calendar controls, spinners, sliders, etc. In addition all of the additional Rapide properties for controls are displayed in the same property sheets as the standard Gen properties.
Studio Developer also has an integrated generation capability for Rapide which enables all of the components of a Rapide application to be generated, installed and assembled from within Studio Developer, again without needing to launch a separate plug-in.
Best wishes,
Darius
