Objects Classes

1. Go to the object navigator.

2. Select the Tools > Parameters main menu item.

3. At the left part select the Custom Metadata item and go to the Object Classes tab.

To create a new object class, execute one of the following operations:

• Click the Add button on the Object Classes tab.

• Select the Add context menu item in the objects list area.

The dialog box with description of a new class opens. The dialog box also enables the user to determine the list of operations, which will be available for objects of this class. Determine required settings and click the OK button to save the class.

To edit the existing class, execute one of the following operations:

• Select the class in the list and click the Edit button.

• Select the class in the list and select the Edit context menu item.

• Double-click the class in the list.

The dialog box for setting up class description, operations and operations handlers opens. Edit required settings and click the OK button to save changes.

To delete one or several classes, select the class(es) in the list and click the Delete button or select the same context menu item.

The class(es) will be deleted after confirmation.

To move a class in the list, select it and use the and buttons. The order of classes in the list affects the order, in which they will be displayed in the context menu and in the list of commands of the New Object button on the ribbon in the object navigator.

A proper set of operations can be set for each custom class. Access permissions can be distributed for these operations (For details see Additional Security Parameters).

The list of operations is formed on the Operations tab, which is available in parameters when editing or creating a class. The Event Handlers tab is used to set a class and a script that will be used to handle operations in the desktop and web applications, respectively.

To save icons and translate information about custom classes into different languages, set the Resources object for classes. To do so, select the existing repository resources in the drop-down list or click the New button.

The following information is saved in the resource:

• Class names.

• Class description.

• Names of operations created for classes.

• Two groups of icons: 16*16 and 32*32.

If required, each class settings can contain their own Resources, which will store information about this class only.

Resources identifiers:

• String resources with the CLSNAMEn identifier are created for class names, where n is the number of the class, for example, CLSNAME1.

• String resources with the CLSDESCRn identifier are created for class descriptions, where n is the number of the class, for example, CLSDESCR1.

• String resources with the CLSn1OPn2<> identifier are created for class operations, where n1 is the number of the class, n2 is the number of the operation, for example, CLS1OP2.

• Collections of small and large icons are stored in graphic resources that have idenSMALLICON and idenLARGEICON identifiers respectively, where iden is the ID of custom class container.

NOTE. After the Resources object is specified, string resources and icons for all existing classes are created automatically. Current names and descriptions are applied to default language.

Setting up of icons requires that the Resource object, in which icons should be stored, is set for all classes or the certain class.

After that use the Large Icon and the Small Icon buttons to select the file with icon for the class in the class description. The icon will be saved in resources. To use the icon, click on the white space next to the buttons and select the icon from the list of existing icons. The large and the small icon should have the same index in the list.

To move custom class settings from test repository into a commercial one, update mechanism is used that is also used for other repository objects. To add custom classes to the update, select them in the list and execute the appropriate context menu item. Classes will be added as special objects. The further work on saving and applying the update is executed in the update manager.
