| - | [[http://click.apache.org/docs/user-guide/html/ch02.html#classes|Page class overview]] | + | Java classes can be accessed by the Velocity templates by adding them to the ''model'' Map of the Page class. Adding can be done explicitely (by calling a method), implizitely (by making them public) or by using an annotation. More: [[http://click.apache.org/docs/user-guide/html/ch02.html#classes|Page class overview]], [[http://click.apache.org/docs/user-guide/html/ch04s02.html#application-autobinding|Autobinding]] |

| + | ==== Manual adding == | ||
| + | |||
| + | Distinguish between plain dynamic data types like ''String'' or ''Date'' and Click Control types like ''Checkbox'' or ''FormTable''. | ||
| + | |||
| + | Plain data types are made available for the Velocity template by calling ''Page.addModel()'' in the constructor of the Page class or in ''Page.onInit()''. | ||
| + | |||
| + | Click Control types must be added with ''Page.addControl()'' in ''Page.onInit()'' | ||
| + | |||
| + | ==== Automatic adding == | ||
| + | |||
| + | As default, all public attributes of a Page class are added automatically to the Page's ''model''. | ||
| + | |||
| + | ==== Adding by annotation == | ||
| + | |||
| + | Alle attributes of a Page, annotated with ''@Bindable'' are added automatically to the Page's ''model''. | ||
| + | |||
| + | The @Bindable annotation is only respected, when autobinding ist set to ''annotation'' in ''click.xml'': | ||
| + | <code xml> | ||
| + | <pages package="sb.translator.page" autobinding="annotation"/> | ||
| + | </code> | ||
| + | |||
| + | Alle Java files must import Bindable: | ||
| + | <code java> | ||
| + | import org.apache.click.util.Bindable; | ||
| + | </code> | ||
| + | |||
| + | <note tip>Using the @Bindable annotation seems to be the best way of binding :?:</note> | ||
