swt java 内嵌ActiveX控件

这里用的是SWT/JFace开发application中SWT自带的org.eclipse.swt.ole.win32 包可以支持内嵌OLE和ActiveX。 具体用法如下:

//创建一个OleFrame做为OLE(或ActiveX)的框架

OleFrame oleFrame = new OleFrame(this, SWT.NONE);

//创建ActiveX的容器,其中的classID是ActiveX的classid,在注册表中可以找到

OleControlSite oleControl = new OleControlSite(oleFrame, SWT.NONE, “classID”);

//OleAutomation类用来执行ActiveX中的方法

OleAutomation oleAutomation = new OleAutomation(oleControl);

//将ActiveX显示在application中

oleControl.doVerb(OLE.OLEIVERB_SHOW);

调用AcitveX中方法的具体过程:

1、不带参数的方法调用

//获取Method Name的ID,Method Name为ActiveX中具体的方法名

int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });

int dispIdMember = regspid[0];

//方法调用

oleAutomation.invoke(dispIdMember);

2、带参数的方法调用

//获取Method Name的ID,Method Name为ActiveX中具体的方法名

int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });

int dispIdMember = regspid[0];

//设置方法的具体参数。Variant数组的长度为Method Name方法参数的个数

//假设有四个参数

Variant[] rgvarg = new Variant[4];

rgvarg[0] = new Variant(fileID);

rgvarg[1] = new Variant(itdsURL);

rgvarg[2] = new Variant(idType);

rgvarg[3] = new Variant(reportURL);

//方法调用

oleAutomation.invoke(dispIdMember, rgvarg);

调用OLE Exemple:Java程序内嵌Word应用程序

package test.swt;

import java.io.File;

import org.eclipse.swt.SWT;

import org.eclipse.swt.graphics.Point;

import org.eclipse.swt.layout.GridData;

import org.eclipse.swt.layout.GridLayout;

import org.eclipse.swt.ole.win32.OLE;

import org.eclipse.swt.ole.win32.OleClientSite;

import org.eclipse.swt.ole.win32.OleFrame;

import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Composite;

public class ActiveXTest

{

private Shell sShell = null;

private Button button = null;

private OleClientSite clientSite;

public static void main(String[] args)

{

Display display = Display.getDefault();

ActiveXTest thisClass = new ActiveXTest();

thisClass.createSShell();

thisClass.sShell.open();

while (!thisClass.sShell.isDisposed())

{

if (!display.readAndDispatch())

display.sleep();

}

display.dispose();

}

/**

* This method initializes sShell

*/

private void createSShell()

{

GridData gridData = new GridData();

gridData.horizontalSpan = 2;

GridLayout gridLayout = new GridLayout();

gridLayout.numColumns = 3;

sShell = new Shell();

sShell.setText("Shell");

sShell.setLayout(gridLayout);

sShell.setSize(new Point(800, 600));

OleFrame frame = new OleFrame(sShell, SWT.NONE);

button = new Button(sShell, SWT.NONE);

button.setLayoutData(gridData);

button.setText("Save");

button.addSelectionListener(new org.eclipse.swt.events.SelectionAdapter() {

public void widgetSelected(org.eclipse.swt.events.SelectionEvent e)

{

clientSite.save(new File("d:/test.docx"),true);

}

});

frame.setSize(800,600);

clientSite = new OleClientSite(frame, SWT.NONE,"Word.Document.8");

clientSite.setSize(400,400);

clientSite.doVerb(OLE.OLEIVERB_SHOW);

}

}

SWT调用ActiveX简单总结

public class SWT_ActivexUtil {

private OleFrame _frame;

private OleControlSite _site;

private OleAutomation _auto;

SWT_ActivexUtil(String activexId, OleControlSite site){

if(site == null){

Shell shell = new Shell();

_frame = new OleFrame(shell, SWT.NONE);

_site = new OleControlSite(_frame, SWT.NONE, activexId);

_auto = new OleAutomation(_site);

}else{

_site = site;

_auto = new OleAutomation(site);; 

}

}

public int getID(String name){

try {

int[] ids = _auto.getIDsOfNames(new String[]{name});

if(ids.length>=0)

return ids[0];

} catch (RuntimeException e) { 

e.printStackTrace(); 

}

return -1;

}

public Variant[] createVariants(String[] paras){

Variant[] vr = new Variant[paras.length];

for(int i=0;i

vr[i] = new Variant(paras[i]);

}

return vr;

}

public Variant getProperty(String prop){

int propId = getID(prop);

Variant v = null;

try {

v = _auto.getProperty(propId);

} catch (Exception e) {

e.printStackTrace();

}

return v; 

}

public void setProperty(String name, String... params){

int propId = getID(name);

if(propId < 0)

return;

if(params.length==1)

_auto.setProperty(propId, new Variant(params[0]));

else{

Variant[] vs = new Variant[params.length];

int i=0;

for(String param:params){

vs[i] = new Variant(param);

i++; 

}

_auto.setProperty(propId, vs);

}

}

public void setProperty(String name, Variant... params){

    int propId = getID(name);

   if(propId < 0)

         return;

    _auto.setProperty(propId, params);

}

public Variant execute(String methodName, Variant... params){

    int mid = getID(methodName);

   if(mid<0)

         return null;

    Variant rtnv;

if(params == null)

    rtnv = _auto.invoke(mid);

else

    rtnv = _auto.invoke(mid, params);

    return rtnv;

}

public Variant execute(String methodName){

   int mid = getID(methodName);

   if(mid<0)

         return null;

    Variant rtnv = _auto.invoke(mid);

     return rtnv;

}

public void addEventListener(int eventID, OleListener listener){

     _site.addEventListener(eventID, listener);

}

public void removeEventListener(int eventID, OleListener listener){

       _site.removeEventListener(eventID, listener);

}

}
