[ Attributes ]

alignAlignmentType Specifies the horizontal alignment of the element.
  • left = left alignment
  • right = right alignment
  • center = center alignment
colspanInteger Specifies the column span of a form element within a multi column form  
defaultString Defines the button that should be activated when the Return key is pressed.

Annotation: The identifier or label of a form button must be specified.

heightString Sets the height of the form element. The height may be specified in absolute or percent terms.

Annotation: See HTML documentation for the attribute height.

helpString Allows to assign a help id for the element. If set, a help symbol will be displayed beside the element, which will generate an onHelp event if the icon is clicked. The id can be used to display a special page of the help system. The help system is not part of the Common-Controls Framework.

To generate the hyperlink some default framework resources where used:
Resource KeyDescriptionDefault optional onclick script handler. The handler can include a {0} placeholder for the help id- the target where to open the hyperlink_blank tooltip for the hyperlinkcontext help

Annotation: A jump screen of the Help system must be specified.

joinBoolean Indicates that two adjacent form elements should be joined together  
noframeBoolean Can be used to hide the border for the control. The buttons will still be displayed above the control (depends on the registered PainterFactory.  
permissionACL With this attribute, access to the element can be restricted.

Authorizations are checked using the object in the user session. The principal object is registered in the session with the method, Principal). It is made available by the application developer by implementing the principal interface. In this manner, any authorization system can be very easily connected within the framework.

Authorizations are always specified in the form of an Access Control List (ACL). What is involved here is a semicolon-delimited list with individual authorizations. The framweork supports the following authorization types, which, however, can be expanded at will by the application developer:

true|false ->
#rolename ->
$functionname ->

valignAlignmentType Specifies the vertical alignment of the element.
  • top = top alignment
  • bottom = bottom alignment
  • center = center alignment
