Object Library  CORE_FRM

This object library contains all of the basic level reusable objects of the CORE. Every CORE based listing and detail form uses some of these objects (toolbar, visual attributes). The different CORE objects are grouped on object library tabs to facilitate direct form development (done without template). See the purpose of individual tabs at their section. 

A general rule for the project that property classes don't have to be subclassed into forms, they can be directly referenced from the objects (forms, blocks) which require them. This helps keeping the size of the development units of the project lower. Other objects (e.g.: the main toolbar, visual attributes, standard parameters) have to be subclassed into the form since internal functions will look for them in the form.

The main toolbar which is included in every form (listing, detail). None of its items (button) are navigable by keyboard. The command item will be fully operational only in the next release of the CORE.

The block is a memory block, its database related properties are set according to this (query, insert, update are set to No and "Single Record" is set to Yes).

Property Class   CORE_LSTB  

Property class for the listing block of the listing form. Disables inserting, deleting and updating in the block by setting these attributes to false design time. It supports changing the color of the currently selected row when the user enters query mode (green) and changing back to normal mode (blue). This functionality is handled in the WHEN-NEW-RECORD-INSTANCE trigger of the block(prop.class).
