    • 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")

    • 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.
