PHP Class Prado\Web\UI\WebControls\TWebControl

TWebControl is the base class for controls that share a common set of UI-related properties and methods. TWebControl-derived controls are usually associated with HTML tags. They thus have tag name, attributes and body contents. You can override {@link getTagName} to specify the tag name, {@link addAttributesToRender} to specify the attributes to be rendered, and {@link renderContents} to customize the body content rendering. TWebControl encapsulates a set of properties related with CSS style fields, such as {@link getBackColor BackColor}, {@link getBorderWidth BorderWidth}, etc. Subclasses of TWebControl typically needs to override {@link addAttributesToRender} and {@link renderContents}. The former is used to render the attributes of the HTML tag associated with the control, while the latter is to render the body contents enclosed within the HTML tag.
