! Introduction
The ''action-deletetiddler'' widget is an [[action widget|ActionWidgets]] that deletes a tiddler. ActionWidgets are used within triggering widgets such as the ButtonWidget.
There are several differences compared to the [[WidgetMessage: tm-delete-tiddler]]:
* The user is not prompted to confirm the deletion
* No automatic updating of the story list
* No special handling of draft tiddlers
! Content and Attributes
The ''action-deletetiddler'' widget is invisible. Any content within it is ignored.
|!Attribute |!Description |
|$tiddler |The title of the tiddler to be deleted (if not provided defaults to the [[WidgetVariable: currentTiddler]] |
! Examples
Here is an example of a button that deletes the tiddler HelloThere. Note:
<$macrocall $name='wikitext-example-without-html'
src='<$button>
<$action-deletetiddler $tiddler="HelloThere"/>
Go to Control Panel "Appearance" tab
</$button>'/>
