How Property inspector files work 281

How Property inspector files work

At start up, Dreamweaver reads the first line of each HTM and HTML file in the

Configuration/Inspectors folder, searching for the comment string that defines the type,

priority, and selection type of a Property inspector. Files that do not have this comment as

their first line are ignored.

When the user makes a selection in Dreamweaver or moves the insertion point to a different

location, the following events occur:

1. Dreamweaver searches for any inspectors that have a within selection type.

2. If there are any within inspectors, Dreamweaver searches up the document tree from the

currently selected tag to check whether there are inspectors for any tags that surround the

selection. If there are no

within inspectors, Dreamweaver searches for any inspectors that

have a selection type of

exact.

3. For the first tag that has one or more inspectors, Dreamweaver calls each inspector’s

canInspectSelection() function. If this function returns the value false, Dreamweaver

no longer considers the inspector a candidate for inspecting the selection.

4. If more than one potential inspector remains after calling the canInspectSelection()

function, Dreamweaver sorts the remaining inspectors by priority.

5. If more than one potential inspector shares the same priority, Dreamweaver selects an

inspector alphabetically by name.

6. The selected inspector appears in the Property inspector floating panel. If the Property

inspector file defines the

displayHelp() function, a small question mark (?) icon appears

in the upper-right corner of the inspector.

7. Dreamweaver calls the inspectSelection() function to gather information about the

current selection and populate the inspector’s fields.

8. Event handlers attached to the fields in the Property inspector interface execute as the user

encounters them. (For example, you might have an

onBlur event that calls the

setAttribute() function to set an attribute to the value that the user enters.)
