Uniquely identifies the catalog item.

Delphi syntax:

property Key: OleVariant;

C++ syntax:

__property OleVariant Key={ read=Get_Key, stored=false };

Description

The Key property serves as the primary identifier for an object. In some cases, Key is a GUID, such as CLSID for a component; in some cases it is the item name, as with roles. To determine the meaning of the Key property, check the Microsoft documentation for the specific collection to which this item belongs.

Note:	If you add a new object to a collection and save it with the Key property of an existing object, you overwrite the existing object. 
===================================================================
Key property (TIBLicensingService)

Sets or returns the license key.

Delphi syntax:

property Key: String;

C++ syntax:

__property AnsiString Key = {read=FKey, write=FKey};

Use Key to set or return the license key.

Note: You must install InterBase 6 to use this feature.

Key codes

Key codes provide a symbolic representation of user key presses.

Unit

Qt

Description

Key codes allow you to represent keyboard values for non-alphanumeric keys. The Qt unit defines special constants for each key the user can press. These constants can then be used to refer to the keystroke in an OnKeyUp or OnKeyDown event handler.

To create a virtual key code for an alphanumeric value, use the Ord method. For example the virtual key code for ??is Ord(??.

The following table lists the key codes defined in the Qt unit:
