/**
|
|
|
14 |
* TLiteral class
|
|
|
15 |
*
|
|
|
16 |
* TLiteral displays a static text on the Web page.
|
|
|
17 |
* TLiteral is similar to the TLabel control, except that the TLiteral
|
|
|
18 |
* control does not have style properties (e.g. BackColor, Font, etc.)
|
|
|
19 |
* You can programmatically control the text displayed in the control by setting
|
|
|
20 |
* the {@link setText Text} property. The text displayed may be HTML-encoded
|
|
|
21 |
* if the {@link setEncode Encode} property is set true (defaults to false).
|
|
|
22 |
*
|
|
|
23 |
* TLiteral will render the contents enclosed within its component tag
|
|
|
24 |
* if {@link setText Text} is empty.
|
|
|
25 |
*
|
|
|
26 |
* Note, if {@link setEncode Encode} is false, make sure {@link setText Text}
|
|
|
27 |
* does not contain unwanted characters that may bring security vulnerabilities.
