! Introduction
|
|
|
|
The button widget displays an HTML `<button>` element that can perform a combination of optional actions when clicked:
|
|
|
|
* Executing any ActionWidgets passed in the `actions` attribute
|
|
* Executing any ActionWidgets that are immediate children of the button widget
|
|
* Execute any integrated actions:
|
|
** Navigate to a specified tiddler
|
|
** Dispatch a user defined [[widget message|Messages]]
|
|
** Trigger a user defined [[popup|PopupMechanism]]
|
|
** Assign new text to a specified tiddler
|
|
|
|
The integrated actions are provided as a shortcut for invoking common actions. The same functionality is available via ActionWidgets, with the exception of the support for highlighting selected popups.
|
|
|
|
! Content and Attributes

The content of the `<$button>` widget is displayed within the button.

|
|
|
''Note:'' In almost all other cases where a TextReference is used as a widget attribute, it will be placed between curly brackets, to [[transclude|Transclusion in WikiText]] the value currently stored there. However, when we use a TextReference as the value of a button widget's <<.attr set>> attribute, we are referencing //the storage location itself//, rather than the value stored there, so we do ''not'' use curly brackets there. //Example:// we could code a button widget that sets the `caption` field of TiddlerA to be the same as that of TiddlerB as:
|
|
|
|
<<.tip """<$macrocall $name=".from-version" version="5.1.18"/> <$macrocall $name=".attr" _="setTitle"/>, <$macrocall $name=".attr" _="setField"/> and <$macrocall $name=".attr" _="setIndex"/> attributes allow specifying Tiddler states ''directly'', without interpreting them as [[TextReferences|TextReference]].
|
|
This is useful for edge-cases where titles may contain characters that are used to denote Tiddler fields or indices (`!!`, `##`)""">>
|
|
|
|
```
|
|
<$button set="TiddlerA!!caption" setTo={{TiddlerB!!caption}} >
|
|
|
|
Press me!
|
|
|
|
</$button>
|
|
```
|
|
|
|
''Tip:'' Set ''class'' to `tc-btn-invisible tc-tiddlylink` to have a button look like an internal link.
