Panels

There are various heitml components that can contain field components. They are called panels. A panel is always associated with an object containing several field values each identified with a unique name. A panel contains field components to display or modify these field values.

There are display panels that only display data and input/output panels that also process input. The same is true for the field components, there are display fields and input/output fields. Display field components just display as text while input/output fields usually render as HTML field components. However also input/output fields can show up just as text depending on the context used. For example a dbform can be controlled from the outside to render as text or as input form.

If a display field is used on an input/output panel it always displays the fields value as text. Input/output field always render as text when used inside a display panel.

Display panels are dbcontainer, dbdisplay, and dbscroller. More precisely the inner part of dbtextcolumn, dbselectlink, and of each repeater nested inside the dbcontainer or dbdisplay.

Typical input/output panels are dbform, mailform, sesform, and sleform.

The baseclass of all panels is panel, see the Class Hierarchy
