Textarea

The textarea should always have a label attached. For this, use the label attribute.

Unlike the input field In there is no placeholder attribute to describe the meaning of a textarea, when no label is set.

<tc:textarea label="Text Area" value="Some text, some text, ..."/> Text Area Some text with more than one row. This is the 2nd row. Read Only Some text (read-only). Disabled Some text (disabled). Some text without a label at the control.

The following textarea should be selected after reloading this page. Use the focus attribute.

<tc:textarea label="Text Area (focus)" focus="true" value="Some Text"/> Text Area (focus) Some Text

The size can be changed with markup large or small.

Tobago is more than just a tag library. The following statements characterize Tobago and make it different from other frameworks: - The focus of Tobago is to create business applications without the need for HTML design. The development of Tobago pages follows more the development of conventional user interfaces than the creation of web pages. - The UI components are abstracted from HTML and any layout information that does not belong to the general page structure. The final output format is determined by the client/user-agent. - A theming mechanism makes it easy to change the look and feel and to provide special implementations for certain browsers. A fallback solution ensures that as much code is reused for new themes as possible. - A layout manager is used to arrange the components automatically. This means, no manual laying out with HTML tables or other constructs is needed. The development of Tobago started in 2002.
