A dragdata object contains the information transferred when a drag and drop operation is performed between two user interface elements.

The type property must be defined and determines how the receiving element will process the information. The types supported by the framework are "number", "string", "dice", "shortcut" and "token", all containing (only) the respective data. Custom types can be identified by any string, but the use of as unambiguous identifiers as possible, considering the purpose, is recommended.

The actual data consists of one or more slots, and each slot contains a combination of the available data items (number, string, shortcut, token and database node). All built in types support only the first slot. It is up to the scripts handling custom types to interpret the data contained in the slots correctly.

Each instance of this object also optionally contains a description string and an icon resource name. The description can be used by elements such as the chat window and hot key bar to apply a descriptive label to the entirety of the drag data. The icon can be used to set a bitmap to be drawn at the mouse cursor while the drag is underway.

If the drag contains dice, all of them are drawn at the cursor. If there are no dice and an icon has been specified, the icon graphic will be used. In the absence of the above, the token prototype graphic is used if a token is defined. If none of the latter information is available, the string value, or finally, the number value, will be used for representing the drag.

To support specialized operations in cases where a default function is applicable, a base dragdata inherited object can be created. An example of such a case could be a token control that attaches extra information to a token, but it is still desired that the drag can be used as a framework supported "token" drag if the custom type is not supported by the target element. To implement this, the custom data should first be set, and the createBaseData function used to create the base object. The returned reference to the base object can then be used to set up data matching a built in type. Base objects can be chained.

The function isType should generally be used by all elements to check the type of a drop operation. It automatically causes further data reads from the object to return information from a matching base object. This functionality is also utilized by the framework, i.e. a custom drag with a supported base data item available in the chain can be used with an out of the box framework element. The currently active data is called top level data. Special cases requiring a rewind of the inheritance chain can use the resetType function.

When drag objects are set using the setData function, here is the expected format of the LUA table used to define the drag object:

  • type: String. Drag object type.
  • icon: String. Icon associated with this drag object.
  • description: String. Description associated with this drag object.
  • dbref: String (or databasenode). Data base node identifier (or databasenode object) associated with this drag object.
  • secret: Boolean. Flag indicating whether drag data should be displayed local only when dropped on chat window.
  • shortcuts: Table of shortcut records. Each shortcut record is a table containing class and recordname string fields. Any shortcut records associated with this drag object.
  • slots: Table of slot records. See below.

Each slot record is a LUA table with the following fields:

  • type: String. Slot type.
  • number: Number. Numeric value associated with this slot.
  • string: String. Textual value associated with this slot.
  • token: String. Token identified associated with this slot.
  • shortcut: Table. Shortcut associated with this slot. Each shortcut record is a table containing class and recordname string fields.
  • dice: Table. Dice associated with this slot. The table contains numerically indexed die resource names.
  • metadata: Table. Metadata associated with this slot.
  • custom: Object. Custom LUA variable associated with this slot. This information will not be saved for drag objects placed on hot key bar.
