Field Detail

tr

public static final WTemplate.Function tr

A function that resolves to a localized string.

For example, when bound to the function "tr", template that contains the placeholder

 ... ${tr:name} ...

 

will be resolved to the value of:

 WString::tr("name")

WTemplate.addFunction(String name, WTemplate.Function function)

block

public static final WTemplate.Function block

A function that renders a macro block.

The function will consider the first argument as the key for a localized string that is a macro block, and additional arguments as positional parameters in that block.

For example, a template that contains:

 ...
 ${block:form-field category}
 ...

 

would look-up the following message:

 <message id="form-field">
 <div class="control-group">
 ${{1}-info}
 </div>
 </message>

 

and render as:

 ...
 <div class="control-group">
 ${category-info}
 </div>
 ...

 

while_f

public static final WTemplate.Function while_f

A function that renders a macro block as long as the given condition is true.

The function will consider the first argument as the condition, and the second argument as the key for a localized string that is a macro block.

Just like the block function, you can provide additional arguments, so the third argument will be what is filled in into {1} in the macro block, etc.

id

public static final WTemplate.Function id

A function that resolves the id of a bound widget.

For example, when bound to the function "id", template text that contains a place-holder

 ... ${id:name} ...

 

will be resolved to the value of:

 t.resolveWidget("name").id()

 

This is useful for binding labels to input elements.
