Creating Property inspectors for locked

content

After you create a translator, you need to create a Property inspector for the content so the

user can change its properties (for example, the file to be included or one of the conditions in

a conditional statement). Inspecting translated content is a unique problem for several

reasons:

■ The user might want to change the properties of the translated content, and those changes

must be reflected in the untranslated content.

■ The Document Object Model (DOM) contains the translated content (that is, the lock

tags and the tags they surround are nodes in the DOM), but the

outerHTML property of

the

documentElement object and the dreamweaver.getSelection() and

dreamweaver.nodeToOffsets() functions act on the untranslated source.

■ The tags you inspect are different before and after translation.

A Property inspector for the

HAPPY tag might have a comment that looks similar to the

following example:

<!-- tag:HAPPY,priority:5,selection:exact,hline,vline, attrName:xxx,¬

attrValue:yyy -->

The Property inspector for the translated HAPPY tag, however, would have a comment that

looks similar to the following example:

The canInspectSelection() function for the untranslated HAPPY Property inspector is

simple. Because the

selection type is exact, it can return a value of true without further

analysis. For the translated

HAPPY Property inspector, this function is more complicated; the

keyword

*LOCKED* indicates that the Property inspector is appropriate when the selection is

within a locked region, but because a document can have several locked regions, further

checks must be performed to determine whether the Property inspector matches this

particular locked region.
