Property Methods

The following methods control the setting and getting of properties on various object types within Cadcorp SIS Desktop.

Properties fall into two categories: members and user-defined attributes. Members are the internal, system properties of an object (e.g. Item ID and Pen on an item or number of overlays on a window).

User-defined attributes are the properties added programmatically by an application or interactively by the user (e.g. "CostPerSqM#").

Note: Some members can only be queried and not set, e.g. Item ID.

Some members have special meaning (each is returned as a space-separated list):

_properties$	- all of the properties of an object (members and attributes).
_properties_edit$	- all of the editable members of an object.
_members$	- all of the members of an object.
_attributes$	- all of the user-defined attributes of an object.

The following object types can have their properties queried and set:

• SIS_OT_CURITEM
• SIS_OT_DEFITEM
• SIS_OT_DATASET
• SIS_OT_OVERLAY
• SIS_OT_WINDOW
• SIS_OT_NOL
• SIS_OT_FTABLE
• SIS_OT_SCHEMA
• SIS_OT_SCHEMACOLUMN
• SIS_OT_THEME
• SIS_OT_THEMECOMPONENT
• SIS_OT_PRINTER
• SIS_OT_SYSTEM
• SIS_OT_OPTION
