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 aren't familiar with creating a component using OO.o API plugin, you may take a look at the MinimalComponent example as a 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:
java.lang.Object
└ 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;
import com.sun.star.uno.XInterface;
Add following members to the class as component properties, it's a list of usable data type
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)); // BOUND & CONSTRAINED public boolean bcBoolA; public Boolean bcBoolClassA; // MAYBEVOID public Object bcObjectA; // MAYBEVOID public Any bcAnyA; // MAYBEVOID // 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("arShortA", PropertyAttribute.MAYBEVOID); registerProperty("arIntA", PropertyAttribute.MAYBEVOID); registerProperty("arLongA", PropertyAttribute.MAYBEVOID); registerProperty("arFloatA", PropertyAttribute.MAYBEVOID); registerProperty("arDoubleA", PropertyAttribute.MAYBEVOID); registerProperty("arStringA", PropertyAttribute.MAYBEVOID); registerProperty("arObjectA", PropertyAttribute.MAYBEVOID); registerProperty("arAnyA", PropertyAttribute.MAYBEVOID); registerProperty("arXinterfaceA", PropertyAttribute.MAYBEVOID); registerProperty("ar2BoolA", PropertyAttribute.MAYBEVOID); registerProperty("boolClassA", PropertyAttribute.MAYBEVOID); registerProperty("charClassA", PropertyAttribute.MAYBEVOID); registerProperty("byteClassA", PropertyAttribute.MAYBEVOID); registerProperty("shortClassA", PropertyAttribute.MAYBEVOID); registerProperty("intClassA", PropertyAttribute.MAYBEVOID); registerProperty("longClassA", 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)); registerProperty("bcAnyA", (short) (PropertyAttribute.BOUND | PropertyAttribute.CONSTRAINED |PropertyAttribute.MAYBEVOID)); registerProperty("mvIntA", PropertyAttribute.MAYBEVOID); registerProperty("mvObjectA", PropertyAttribute.MAYBEVOID); registerProperty("mvAnyA", PropertyAttribute.MAYBEVOID); registerProperty("mvXinterfaceA", 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.
Delopyment
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
