<<.from-version "5.3.0">> The ''\widget'' [[pragma|Pragmas]] is used to [[define custom widgets|Custom Widgets]]. It is a shortcut syntax for the SetVariableWidget with an implicit ParametersWidget.
|
||
|
|
|
||
|
|
The usual form allows custom widgets to span multiple lines:
|
||
|
|
|
||
|
|
```
|
||
|
|
\widget <widget-name>(<param-name>[:<param-default-value>],<param-name>[:<param-default-value>]...)
|
||
|
|
<multiple-line-definition-text>
|
||
|
|
\end [<widget-name>]
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that the `\end` marker can optionally specify the name of the widget to which it relates which allows widget definitions to be nested.
|
||
|
|
|
||
|
|
There is also a single line form for shorter widgets:
|
||
|
|
|
||
|
|
```
|
||
|
|
\widget <widget-name>(<param-name>[:<param-default-value>],<param-name>[:<param-default-value>]...) <single-line-definition-text>
|
||
|
|
```
|
||
|
|
|
||
|
|
The first line of the definition specifies the widget name and any parameters. Each parameter has a name and, optionally, a default value that is used if no value is supplied on a particular call to the widget. The lines that follow contain the text of the widget text (i.e. the snippet represented by the widget name), until `\end` appears on a line by itself:
