Tinderbox v9 Icon


Many aspects of Tinderbox are set and stored by using attributes, such as a note's name, the colour of its icon in a Map view, etc. Attributes apply to every note (including special notes like separators and adornments) and agents.

An Attribute has a case-sensitive name, a value type, a value and an optional default value. Some attributes are read-only, meaning they cannot be modified by the user. If no default value is set the attribute is empty/zero/false/etc., according to data type. There are two primary types of attributes:

Additionally, system attributes may be:

The two primary attribute listings, General and User, and their data types, etc., are covered in more detail in the Attributes section and all General attributes are described system attribute list. Values used by attributes are often inherited. There are also naming rules for attributes.

System attributes will generally have a default value which may be set via Preferences or, at document level, by editing the default value.

In Tinderbox all attributes are global in the sense that they exist and can be given a value for any note or agent, even if it might not be useful in a particular case. Just ignore attributes when they do not make sense. Put in database terms, Tinderbox implements one big table (flat file style), rather than a set of related tables.

The attributes of TBX document are set at document creation by Tinderbox and may be altered via the Document Inspector's System tab, though some can also be set via Document Settings. Thus you can set the Map view's background colour by opening the document's Info view and changing the $MapBackgroundColor attribute; be aware changing this attribute only affects the document if the current 'item' is the document and not a note, i.e. no note is currently selected.

In Action code, attribute values are referred to in Tinderbox attribute coding by using a '$' prefix, e.g. $Color returns the _value_ for the attribute 'Color' (i.e. the note's colour in the view pane). By general informal usage, the Tinderbox community will also use (misuse!) the $-prefix in general writing to make explicit they are talking about a the name of an attribute. Thus "See the $Name of…" or "You can use the $Height…" where in both cases the context implies that "$X" means the "the attribute named X". This latter convention is used in aTbRef.

There are a variety of methods for editing attribute values.

Give consideration to naming attributes in a manner that matches Tinderbox's assumptions. If attribute names are wrong, either due to import or because they were created before reading the notes on naming styles, attributes can be renamed.

Attributes all have one of a number of data types.
