PHP Class Prado\Web\UI\WebControls\TLabel

TLabel displays a piece of text on a Web page. Use {@link setText Text} property to set the text to be displayed. TLabel will render the contents enclosed within its component tag if {@link setText Text} is empty. To use TLabel as a form label, associate it with a control by setting the {@link setForControl ForControl} property. The associated control must be locatable within the label's naming container. If the associated control is not visible, the label will not be rendered, either. Note, {@link setText Text} will NOT be encoded for rendering. Make sure it does not contain dangerous characters that you want to avoid.
