Property Inspectors 123

A simple Property inspector example

The following Property inspector inspects a fictional tag called

INTJ. The INTJ tag is empty (it

has no closing tag), so its selection type is

exact. As long as the selection is an INTJ tag, the

Property inspector appears—so the

canInspectSelection() function returns true every time.

To have a different inspector appear, depending on the value of the

INTJ tag’s TYPE attribute, for

example, the

canInspectSelection() function must check the value of the TYPE attribute to

determine which Property inspector is the right one. (This is how the keywords and description

Property inspectors work, because “keywords” and “description” are not tags but values of the

META tag’s NAME attribute.)
