How to display buttons from pl/sql?

Question

I am creating a page from pl/sql. Is there a way to display a html db button from pl/sql? I have looked in htmldb_item and wwv_flow_item but there is no function for buttons. I can of cause make my own using the two gif that the I can se the buttons consists of, but it would be easyer if there were a function some where :-)

The PL/SQL packahe HTP allows you to output data (HTML etc) that is to be streamed to the browser. Very simply example. Create a dynamic PL/SQL region in HTMLDB and code the following as the contents:
begin
  HTP.prn( 'Hello World );
end;So it is fairly simply to add HTML (or other Mime type) contents to a HTMLDB generated web page using custom written PL/SQL.
However, despite the fact that a button can easily be generated from a PL/SQL proc, a button influences the "processing" of a page. Buttons are used to submit forms, trigger JavaScript and so on.
Thus you need to think very carefully as to what that custom button is going to do and hook into HTMLDB's dynamic web page and flow processing.. And why you're not using (and bypassing) HTMLDB itself?
