! Introduction
|
|
|
|
The <<.wid qualify>> widget sets a variable
|
|
to a unique string that encodes its position within the widget tree, as identified by the stack of transcluded tiddlers that lead to that position.
|
|
|
|
Internally, it is implemented using the transclusion variable.
|
|
|
|
! Content and Attributes
|
|
|
|
The content of the <<.wid qualify>> widget is the scope for the value assigned to the <<.var name>> variable.
|
|
|
|
|!Attribute |!Description |
|
|
|//title// |The prefix for the string, normally a tiddler title |
|
|
|//name// |The name of the variable to be set to the unique string |
|
|
|
|
! Examples
|
|
|
|
The two examples below are identical, but produce different results because the second one has been transcluded from [[another tiddler|$:/editions/tw5.com/widget-examples/qualify-transcluded]].
|
|
|
|
Each example shows the result of calling <<.var qualify>> and then the value of the <<.vlink transclusion>> variable.
|
|
<$macrocall $name=".example" n="1"
|
|
eg="""<$qualify title="BaseTiddler" name="iamnotanumber">
|
|
<ul>
|
|
<li><code><<iamnotanumber>></code></li>
|
|
<li><code><<transclusion>></code></li>
|
|
</ul>
|
|
</$qualify>

|
! Remarks
|
|
|
|
In most cases it will be simpler to use the [[qualify Macro]]. |
