About the PropertySet Example

This example shows how to write a component and set it's properties. Once it is deployed, we'll be able to use a document with OO.o Basic macro to test the component and get its property informations.

First of all, let's look at the example test document “/API/Samples/Java/PropertySet/test/”. You could also get it from here File:PropertySetTest.odt. The example button triggers a macro which creates the “PropTest” example service and displays the supported interfaces and properties. You can take a closer look to the Basic macro by editing the macro:
Select Tools -> Macros -> Organize Macros -> StarOffice Basic, navigate into the document section of “PropertySetTest.odt”, select the Standard -> “PropTest” module, select the “PropetySetTest” macro and press the edit button.

Here is the OpenOffice.org Basic code of the macro:

  REM  *****  BASIC  *****
  Sub PropertySetTest
	dim propTest as object
	propTest = createUnoService("org.openoffice.sdk.example.propertyset.PropTestService")
	msgbox propTest.dbg_supportedinterfaces
	msgbox propTest.dbg_properties
  End Sub

CreateUnoService() method initializes the component / creates the service using service name “org.openoffice.sdk.example.propertyset.PropTestService”, the name which should be exactly the same as the service name property when component is written.

    private static final String[] m_serviceNames = {
        "org.openoffice.sdk.example.propertyset.PropTestService" };

If you would like to know more detail about above code, please read OO.o Basic chapters(English) or (Chinese version).

Create component project

The process to create the PropertySet project could refers to MinimalComponent project. Some important settings are addressed here. If you don't familiar with creating a component using OO.o API plugin, you may take a look at MinimalComponent example as starting point.

Use OpenOffice.org Component wizards

Set the project details
Project Name: PropertySet
Class Name: PropTest
Package: org.openoffice.sdk.example.propertyset

Define New Data Type

Service Property Name: PropertyTestService (it's default value)
Interface: com.sun.star.lang.XServiceInfo

Edit the Source file: PropTest.java

Change the Class definitions to:
public final class PropTest extends PropertySet implements com.sun.star.lang.XServiceInfo

the inherited relation between PropertySet and WeakBase is:

   └ com.sun.star.lib.uno.helper.WeakBase
     └ com.sun.star.lib.uno.helper.ComponentBase
         └ com.sun.star.lib.uno.helper.PropertySet

Import necessary libraries:

import com.sun.star.lib.uno.helper.PropertySet;
import com.sun.star.beans.PropertyAttribute;
import com.sun.star.lang.XTypeProvider;
import com.sun.star.uno.Any;
import com.sun.star.uno.Type;

Add following members to the class as component properties

public boolean boolA;
public char charA;
public byte byteA;
public short shortA;
public int intA;
public long longA;
public float floatA;
public double doubleA;
public String stringA; // MAYBEVOID
public Object objectA; // MAYBEVOID
public Any anyA; // MAYBEVOID
public Type typeA;// MAYBEVOID
public XInterface xinterfaceA;// MAYBEVOID
public XTypeProvider xtypeproviderA;// MAYBEVOID
public boolean[] arBoolA; // MAYBEVOID
public char[] arCharA; // MAYBEVOID
public byte[] arByteA; // MAYBEVOID
public short[] arShortA; // MAYBEVOID
public int[] arIntA; // MAYBEVOID
public long[] arLongA; // MAYBEVOID
public float[] arFloatA; // MAYBEVOID
public double[] arDoubleA; // MAYBEVOID
public String[] arStringA; // MAYBEVOID
public Object[] arObjectA; // MAYBEVOID
public Any[] arAnyA; // MAYBEVOID
public XInterface[] arXinterfaceA; // MAYBEVOID
public boolean[][] ar2BoolA; // MAYBEVOID 
public Boolean boolClassA; // MAYBEVOID
public Character charClassA; // MAYBEVOID
public Byte byteClassA; // MAYBEVOID 
public Short shortClassA; // MAYBEVOID 
public Integer intClassA; // MAYBEVOID
public Long longClassA; // MAYBEVOID
public Float floatClassA; // MAYBEVOID
public Double doubleClassA; // MAYBEVOID
// readonly
public int roIntA= 100;
public Integer roIntClassA= new Integer(100); 
public Object roObjectA= new Integer(101);
public Any roAnyA= new Any( new Type(int.class), new Integer(102));
public boolean bcBoolA;
public Boolean bcBoolClassA; // MAYBEVOID
public Object bcObjectA; // MAYBEVOID
public Any bcAnyA;       // MAYBEVOID
public Integer mvIntA;
public Object mvObjectA;
public Any mvAnyA;
public XInterface mvXinterfaceA;

In the constructor “PropTest( XComponentContext context )”, initialize those properties using registerProperty() method, the method registers a property with this class. It is presumed that the name of property is equal to the name of the member variable that holds the property value.

registerProperty("boolA", (short) 0);
registerProperty("charA", (short) 0);
registerProperty("byteA", (short) 0);
registerProperty("shortA", (short) 0);
registerProperty("intA", (short) 0);
registerProperty("longA", (short) 0);
registerProperty("floatA", (short) 0);
registerProperty("doubleA", (short) 0);
registerProperty("stringA", PropertyAttribute.MAYBEVOID);
registerProperty("objectA", PropertyAttribute.MAYBEVOID);
registerProperty("anyA", PropertyAttribute.MAYBEVOID);
registerProperty("typeA", PropertyAttribute.MAYBEVOID);
registerProperty("xinterfaceA", PropertyAttribute.MAYBEVOID);
registerProperty("xtypeproviderA", PropertyAttribute.MAYBEVOID);
registerProperty("arBoolA", PropertyAttribute.MAYBEVOID);
registerProperty("arCharA", PropertyAttribute.MAYBEVOID);
registerProperty("arByteA", PropertyAttribute.MAYBEVOID);

registerProperty("floatClassA", PropertyAttribute.MAYBEVOID);
registerProperty("doubleClassA", PropertyAttribute.MAYBEVOID);
registerProperty("roIntA", PropertyAttribute.READONLY);
registerProperty("roIntClassA", PropertyAttribute.READONLY);
registerProperty("roObjectA", PropertyAttribute.READONLY);
registerProperty("roAnyA", PropertyAttribute.READONLY);
registerProperty("bcBoolA",(short) ( PropertyAttribute.BOUND | PropertyAttribute.CONSTRAINED));
registerProperty("bcBoolClassA", (short) (PropertyAttribute.BOUND |PropertyAttribute.CONSTRAINED | PropertyAttribute.MAYBEVOID));
registerProperty("bcObjectA", (short) (PropertyAttribute.BOUND | PropertyAttribute.CONSTRAINED | PropertyAttribute.MAYBEVOID));

For information of PropertyAttribute, please visit SDK docuement: SDK_DIR/docs/java/ref/com/sun/star/beans/PropertyAttribute.html The document can be loaded into browser when the editing cursor on “PropertyAttribute” string in the editor and then press keys Alt + F1.


Deploy the component and load PropTest.odt to test your component. After the button pressed, two message boxes will show this component's supported interfaces and it's attributes.

msgbox propTest.dbg_supportedinterfaces
msgbox propTest.dbg_properties
