p4a_Application:
The application itself, the receptor of the user events and the container of all objects
p4a_Control:
Base class
|
|---------------->>p4a_BarMenu:
| menu bar containing (at the moment) only 'main items'.
|
|---------------->>p4a_ListView:
| List View to represent rows of a table or an array.
| It can responds to several user events like column
| click, row click, etc
|
|---------------->>p4a_Form:
| Form to maintain and display data of a source that can
| be a table or an array, it has events like update,
| insert, next, previous, unlock...
|
|---------------->>p4a_SimpleForm:
| Form not linked to a 'DataSource' object, it only has
| two events, one of this sends all data fields to the
| server-side.
|
|---------------->>p4a_Panel:
| The other container of the p4a framework. This is an
| important object that contains other objects, in the same
| way of p4a_Application, and it controls the layout
| disposition of all ones. One important thing of this
| container is that it can be invisible, doing, by this way,
| all its objects invisibles so. This object acts as
| the 'frame' control in Visual Basic.
|
|------------------>>p4a_Label:
| A simple label that contains optionally an image.
|
|------------------>>p4a_PlainButton:
| A simple button that responds to the click event and
| can have an image.
|
p4a_DataSource:
Object not visible that has to be passed to a Form or a ListView and that implements some methods like getRecords. The source of the data can be a table in a database or whatever that implements the interface methods of DataSource.
