New Icons

All icons have been renewed as you can see in the following example: the Preferences dialog.

New KB Explorer

The old Folder view has been renamed to the KB Explorer


Note: Tables are only shown if you go to Tools / View Tables.

Renewed Work with Objects Tool window

With Tools / Work with Objects you access this tool window that lets you select objects, view its properties and do several operations with Right-click on selected objects.


Note: The Latest Changes View tool window has been deprecated, and you get the same feature filtering the objects in this tool window.

Domains support Modules

With Tools / View Domains you access the Domains of your KB. Note that they can belong to Modules now. (Btw, several are already in modules and may be read-only: More information at: GeneXus Core module)


Colors are first class citizens

With the new Color Palette object, you can define Color Palettes and reference them from Themes.

More Information: Color Palette object

Abstract Layout Editor for Web and Smart Devices: Classes can be edited in Properties Window

The class associated to the selected control or object property can be now edited right there while you are editing the Object (e.g. Web Panel). 
When you change a value in the Class tab of the properties window, the associated theme is opened so that you are aware of the fact that you are starting to edit the Theme (e.g. Carmine) and not the object (e.g. Web Panel RwdMasterPage) itself.


Create Selected Object feature

While you are coding, you can create new objects:



Properties Window improved

Now you can filter those properties that were modified


Languages Editor improved


Attribute / Variable selector improved


Import images with multiple densities

When designers deliver to you images with multiple densities, all in a .zip file, you now can import that .zip and GeneXus automatically creates one image object containing the different images by density.

More information: Image object
