public class A
extends E4HtmlContentElement
implements E4HtmlElement_Intf

Main class for building anchor tags. An anchor tag provides a link (HREF) to another page (in our case a E4Method) or a E4JavaScript that is executed when the content of the A tag is clicked.

Constructor Detail

A

public A(E4EventHandlerA handle)

Create an <A>-tag, using an event handler. This results into a <A OnClick=".." > tag, using E4JavaScript to execute some action defined in the handler due to a specified event in the handler (e.g. On-Click, On-Mouse-Over, ..).

Parameters:

handle - the event-handle

A

public A(A href)

A

protected A()

A

public A(E4Method functionname)

Create an <A>-tag, using the specified E4Method as link to a function that shall be executed when this link becomes activated by the user.

Parameters:

functionname - the function to be called

See Also:

A(String, e4s.html.E4Method)

A

public A(java.lang.String question,
         E4Method functionname)

Create an <A>-tag, using the specified E4Method as link to a function that shall be executed when this link becomes activated by the user.

Parameters:

question - a question that will be poped up first, the execution continues only if the user selects the "Yes" button in this dialog. The message is displayed using a E4JavaScript function.
