Developer's Guide Examples

The Developer's Guide comes with a wide range of examples from all application areas which shows the use of the API in the context of the different functional areas. Furthermore the examples can be used as a first starting point to modify an existing example to their own needs.

Some fo the examples need a running office instance listening on a port. If this is necessary you will get further information in the makefiles.

All examples marked with a are executable and be started using a run target in the makefile. The name of the binary (C++) can differ compared to the source file, please see the run target in the appropriate makefile. Some of the examples which create a component have no run target. In these cases a document is provided which instantiates and runs the component (see the makefile output). Also the Basic examples provide documents which use and shows the implemented functionality. The database and forms examples need a running database, please see the description below. But note that is not described in detail how to create a working data source (see the office help).

ComponentTreeTraversal Helper classes for traveling through a tree of FormComponent's.
ControlLock Helper class for implementing the locking of control depending on the state of the underlying RowSet.
ControlValidation This is the main class for the control validation example. It creates a sample document, fills it with controls, and attaches several validators to those controls
ControlValidator Base class implementing the common denominator for components validating form controls.
DataAwareness This class implements the basic example for a form working on a database. Two tables will be created and a form (writer document) with a bussiness example will fill its fields from these tables.
DateValidator The class DateValidator implements an validator for a form control, which can check the content of a form date field.

InteractionRequest A simple implementation of a XInteractionRequest. Not tied to the form layer example, but a general helper.
KeyGenerator Helper class which is able to generate (unique) keys for a (RowSet ) column. An instance of this class can be tied to a specific row set column. It then monitors the state of the underlying row set, and upon inserting a new record into it (two operation modi are possible here), it automatically inserts a newly created (two modi, too) key into the column.
ListSelectionValidator The class ListSelectionValidator implements an validator for a form control, which can veto certain selections in a list box control.
NumericValidator The class NumericValidator implements an validator for a form control, which can veto certain values in every control which allows exchanging numerical values.
SingleControlValidation Though form documents feature inbuilt mechanisms for visually indicating invalid control content (see com.sun.star.form.validation for discussions about validity), the ControlValidation example extends this. The validity state of every control in this example, as well as possible explanations for invalidity, are displayed in dedicated texts. The SingleControlValidation class ties together a validatable control and those status texts.
SpreadsheetDocument A specialized DocumentHelper which represents a spreadsheet document, and offers some form related functionality. For instance, this class allows the creation of CellValueBinding instances, which can be used to couple the content of a form control with the content of a spreadsheet cell.

Accessibility examples
Example Description
ConnectionTask A timer task that tries to (re-)connect to a running Office application. When it can not detect an Office application that accepts connections then it waits for some time and tries again.
EventHandler Handle all events that are used by this tool. It is called by the EventListenerProxy class with somewhat preprocessed events.
EventListenerProxy This proxy runs in its own thread to avoid deadlocks with the Office it listens to. It waits for top window events to be informed of new or removed top level windows and for some accessibility events that are relevant to display the currently focused object.
GraphicalDisplay This widget displays a graphical representation of the currently focused object. The focused object is painted as a green rectangle and its ancestors as gray rectangles to give an impression of the relative location of the objects.
IAccessibleObjectDisplay This interface is implemented by all classes that display the currently focused object, namely GraphicalDisplay and TextualDisplay. It allows the owner of the display classes to tell them to display a specific object: usually the focused object.
MessageArea A text area that shows messages about what the tools is currently doing.
NameProvider In contrast to the Java Accessibility API which uses Strings for event types, roles, states, and relation types, the UNO Accessibility API uses numbers for this task. In order to present them to the user in a more readable form this class returns the string name for each event, role, state, or relation.
RegistrationThread When a new window appears or an existing one is removed the tool registers or unregisters at all the window's children as accessibility event listener. This is handled by RegistrationThread objects in their own threads so that the user interface is not blocked.
SSR The main class sets up the user interface and starts the ConnectionTask object that eventually will initiate a connection to a running Office application and in turn will create RegistrationThread objects to register at all Office windows as accessibility event listener and thus gets informed about the currently focused object.
TextualDisplay Show some textual information about the currently focused object like its name, description, and role.
