通过RCP创徏的view�Q�怎样直接昄��出来

Ke — Fri, 08 Jun 2012 03:25:00 GMT

新创建的VIEW已经加到透视图中,但是打开�E�序时就是不昄��相应的视�?

解决�Ҏ��:

原来是设�|�了�q�个��D��?/p>

configurer.setSaveAndRestore(true);
代码如下:

package com.act.mac.upload.intro;

import org.eclipse.ui.application.IWorkbenchConfigurer;

import org.eclipse.ui.application.IWorkbenchWindowConfigurer;

import org.eclipse.ui.application.WorkbenchAdvisor;

import org.eclipse.ui.application.WorkbenchWindowAdvisor;

public class ApplicationWorkbenchAdvisor extends WorkbenchAdvisor {

private static final String PERSPECTIVE_ID = "com.act.mac.upload.perspective";

public WorkbenchWindowAdvisor createWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) {

return new ApplicationWorkbenchWindowAdvisor(configurer);

}

public void initialize(IWorkbenchConfigurer configurer) {

super.initialize(configurer);

//configurer.setSaveAndRestore(true);//注释掉就OK�?/span>

}

public String getInitialWindowPerspectiveId() {

return PERSPECTIVE_ID;

}

setShellStyle(�q�里可以��L��讄��样式);能够�? �|�的样式如下�Q�（以下属性可以多选，但是某些属性相冲突时会��D��讄��的其他属性失效）

SWT.BORDER //建立一个有�Ҏ��但没有标题栏的窗�?/span>
SWT.CLOSE //建立一个只有关闭按钮的�H�口
SWT.MIN  //建立一个不能最大化的窗�?/span>
SWT.MAX, //建立一个可以最大化最��化的窗�?/span>
SWT.NO_TRIM //建立一个没有�Q何边界和标题栏的�H�口

往Eclipse RCP视图中添加右键弹��单（轉）

Ke — Mon, 27 Jul 2009 05:50:00 GMT

源文�Q�http://hi.baidu.com/wyyhzc/blog/item/dbb498196a493e4042a9ad11.html
往eclipse的默认NavigationView中，��d��右键菜单��Ҏ��非常�Ҏ��的，甚至不需要自己写代码�Q�只要在plugin.xml中添加扩展项便可以了�?br /> 但是�q�远�q�达不到我们的要求。如果要我们在自��q��rcp�E�序的View中添加右键弹��单就不是很容易了。现在我介绍一下如何在一个树视图中针对不同的TreeObject��d��不同的右键弹��单的�Ҏ��?br /> 如果不清楚如何构��Z��个树�Q�请参�?/font>http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/CatalogSWT-JFace-Eclipse.htm, �q�里有很多关于eclipse Tree的实例。简单将来，Eclipse中创建树有两�U�，一�U�是使用SWT提供的树�Q�依照一定的格式�l�其提供数据�Q�我自己只用�q�种�Ҏ��创徏一些简单的�? 静态的树。另一�U�方法，针对于RCP�E�序�Q�可以��用JFace提供的TreeViewer�c�，非常灉|��q�且易于扩展。��用TreeViewer需要实�? ITreeContentProvider接口和ITreeLableProvider接口。由于我的时间有限，不能向大家提供具体的实现�Ҏ��Q�请原谅�? 可以参考以下文章：http://eclipse.org/articles/treeviewer-cg/TreeViewerArticle.htm
在大体了解了如何构造一个树之后�Q�我们下面就来介�l�右键弹��单context menu的实现方法�?br /> 一个TreeViewer 必须�l�承ViewPart�Ҏ��Q��ƈ且重写其中的createPartControl(Composite parent)�c�R�?/font>

1    public void createPartControl(Composite parent) {
2
3    /* Set the imput data and image model of the tree viewer,
4    * and layout the viewer on the left part of the composite.
5    */
6     viewer = new TreeViewer(parent);
7     viewer.setContentProvider(new ViewContentProvider());
8     viewer.setLabelProvider(new ViewLabelProvider());
9     viewer.setInput(createDummyModel());
10
11   createActions();
12   createMenus();
13   createContextMenu(parent);
14
15   //handles the actions related with treeviewer.
16   makeActions(parent);
17 }
其中�Q�第7�?行�ؓ讄��TreeViewer的内�Ҏ��供器、图像提供器、以及初始化时的输入数据。第13行�ؓ创徏右键弹出菜单�?br />
1     private void createContextMenu(Composite parent) {
2
3          MenuManager mgr = new MenuManager();
4          mgr.setRemoveAllWhenShown(true);
5          mgr.addMenuListener(new IMenuListener() {
6              public void menuAboutToShow(IMenuManager manager) {
7                 fillContextMenu(manager);
8              }
9          });
10     Menu menu = mgr.createContextMenu(viewer.getControl());
11      viewer.getControl().setMenu(menu);
12     getSite().registerContextMenu(mgr, viewer);
13   }
�W?行代�? 中，setRemoveAllWhenShown(true)的作用是清空以前昄��的菜单项�Q�当触发了menu事�g�Ӟ��重新填充 �Q�fillContextMenu�Q�，所以如果不把removeAllWhenShow�|��ؓtrue的话�Q�每点一下右键你��׃��看到菜单��多��Z��倍来�? Menu是swt的控�Ӟ��而Menumanager是Jface中的控�g�Q�不象SWT那样直接同底层打交道。用MenuManager可以创徏��Z��? Menu对象。第十行mgr.createContextMenu(viewer.getControl());�q�里的viewer即�ؓ上面的viewer。第十一行，然后我们��树的setMenu�Ҏ��树控�g与Menu控�g联系在一起就好了�?br /> 最重要的是�W�十二行�Q�这是context menu能不能显�C�的关键。一个视图中可以有多个context menu, 而每一个context menu都必��L��册给workbench。这需要通过调用org.eclipse.ui.IWorkbenchPartSite.registerContextMenu(MenuManager menuManager, ISelectionProvider selectionProvider)或者（当有多个注册的context menu�Ӟ��org.eclipse.ui.IWorkbenchPartSite.registerContextMenu(String menuId, MenuManager menuManager, ISelectionProvider selectionProvider) 增加的参数menuId用于区分不同的context menu�?br /> 接下来，我们有两�U�方法来创徏右键弹出菜单��V��第一�U�，实现fillContextMenu()�Ҏ��。典型的实现代码如下�Q?br /> 1     protected void fillContextMenu(IMenuManager manager) {
2
3         manager.add(openAction);
4         manager.add(removeAction);
5          manager.add(addAction);
6               }

�q�些Action都可��p��己定义创建�?br /> 另外的方法，可以�~�辑plugin.xml文�g。不需要自己写��M��代码便可以显�C�出自己惌��的弹出项�?br /> �q�次先讲到这里，下次介绍另外的一�U�实现方式。（主要是由于刚创徏Blog�Q�不知道如何插入囄��Q�这么写太费劲也太枯燥了�Q�相信大家一定不能忍了吧�Q�咱们下�ơ再�?/font>�Q?br />

eclispe RCP ��技巧（轉）

Ke — Mon, 27 Jul 2009 05:46:00 GMT

一、同时关闭所有打开的view

在view�?只有一个close,每次只能关闭当前�H�口
在eclipse的编辑窗口的标题上点右键,里面�?close All
可以使用遍历的方法，遍历所有打开的View�Q�然后将光��藏：
AsyncUtil.asyncExec(new Runnable()
{
       public void run()
       {
             IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
             IViewReference[] iViewReferences = page.getViewReferences();
             for (IViewReference iViewReference: iViewReferences)
                  if (!ID.equals(iViewReference.getId()))
                       page.hideView(iViewReference);
        }
});
二、RCP中��生目标区的Bar

产生�U�线区域的Bar,实现�Ҏ��如下�Q?br /> 1、这个是perspective�Q�要创徏多个perspective�Q�然后设�|�某个�ؓactive
2、在WorkbenchWindowAdvisor中preWindowOpen内，加下面这�D�代�?br /> public void preWindowOpen() {
        IPreferenceStore apiStore = PrefUtil.getAPIPreferenceStore();
        apiStore.setValue(IWorkbenchPreferenceConstants.DOCK_PERSPECTIVE_BAR,
                IWorkbenchPreferenceConstants.TOP_RIGHT);
        apiStore.setValue(
                IWorkbenchPreferenceConstants.SHOW_TRADITIONAL_STYLE_TABS,
                false);
}
3、需要加 config.setShowPespectivebar(true);
三、RCP��目�Q�－�H�口关闭事�g
在ApplicationWorkbenchWindowAdvisor中override
public boolean preWindowShellClose() {
        // do nothing, but allow the close() to proceed
        MessageBox msgBox = new MessageBox(new Shell(), SWT.YES|SWT.NO|SWT.ICON_QUESTION);
        msgBox.setText("退出系�l?);
        msgBox.setMessage("��定退出系�l?");
        if(msgBox.open()==SWT.YES){
            return true;
        }
        return false;
    }
以后使用IWorkbenchWindow的getShell().close();都会调用该处代码.
四、在RCP中设计界面适合桌面大小

final int screenWidth = Display.getCurrent().getBounds().width;
final int screenHeight = Display.getCurrent().getBounds().height;

五、Treeviewer中通过代码�Q�选中树上的某个node节点
StructuredSelection sel=new StructuredSelection(node);
tree.setSelected(sel);
六、TreeViewer实现双击展开、关�?nbsp;
private class DoubleEventPro implements MouseListener {
        public void mouseDoubleClick(MouseEvent e) {
            TreeItem item = viewer.getTree().getItem(new Point(e.x, e.y));

            if (item != null && item.getItem(0).getText().trim().length() == 0) {
                viewer.expandToLevel(item.getData(), 1);
                return;
            }

            if (item != null && item.getItemCount() > 0
                    && item.getItem(0).getText().trim().length() > 0) {
                item.setExpanded(!item.getExpanded());
            }
        }

        public void mouseDown(MouseEvent e) {
        }
        public void mouseUp(MouseEvent e) {

}
}
七�?如何屏蔽掉视囄��口上的右键弹��单？

�Ҏ��一�Q�在 postWindowOpen() 中执行下面语�?
PlatformUI.getWorkbench().getDisplay().addFilter(SWT.MouseUp, new Listener() {
    public void handleEvent(final Event event) {
        if(event.widget == your editor && event.button == 3) {
            int hwndCursor = OS.GetCapture ();
            OS.PostMessage(hwndCursor, OS.WM_LBUTTONDOWN, hwndCursor, OS.HTCLIENT | (OS.WM_MOUSEMOVE << 16));
        }
    }
});

其它�Q�org.eclipse.ui.internal.presentations.util包中的StandardViewSystemMenu�c�L��制着�q�些菜单�Q�还没来得急仔�l�研�IӞ��研究�q�后再补�?/font>

八、在使用tableviewer的时候导入大量数据的问题

创徏了一个tableviewer�Q�然后��用setInput�Ҏ��导入数据�Q�如果数据量很大的话�Ҏ��无效率可言了，以下是几�U�解决的�Ҏ��Q?/font>

�Ҏ��一�Q�通过�U�d��滚动条来辑ֈ�自动加蝲的目的，在滚动条的事件中加入��页的代码，可以参考《Eclipse从入门到�_�N��》第二版的P383

�Ҏ��二：分页昄��Q?/font>http://www.eclipseworld.org/bbs/read-cec-tid-11678-keyword-table.html�Q?/font>

�Ҏ��三：使用 Virtual Tables�Q�JFace3.2的Viewer已经支持SWT.VIRTUAL样式
http://www.eclipse.org/articles/Article-SWT-Virtual/Virtual-in-SWT.html

1 int COUNT = 10000;
2 final String [] itemStrings = new String [COUNT];
3 for (int i = 0; i < COUNT; i++) {
4   itemStrings = "item " + i;
5 }
6 final Table table = new Table(parent, SWT.BORDER | SWT.VIRTUAL);
7 table.addListener(SWT.SetData, new Listener() {
8   public void handleEvent(Event event) {
9     TableItem item = (TableItem)event.item;
10     int index = event.index;
11     item.setText(itemStrings [index]);
12   }
13 });
14 table.setItemCount(COUNT);

九、在透视囑ֿ��h��式栏中同时显�C�多个透视囑ֿ��h��?/font>

如果在程序中做了多个个透视图，默认只显�C�初始透视囑ֿ��h��式，每次都要打开透视�䏀�—other�Q�特�ȝ��Q�所以，一下提供两�U�方法：

1、在切换栏中昄��
public class PIMWorkbenchAdvisor extends WorkbenchAdvisor {
    @Override
    public void postStartup() {
        super.postStartup();
        IWorkbenchWindow activeWorkbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        //2007.01.11 讄��同时昄��多个透视图标
        PerspectiveBarManager barManager=((WorkbenchWindow)activeWorkbenchWindow).getPerspectiveBar();
        if(barManager != null){
            IPerspectiveDescriptor mailPerspective = WorkbenchPlugin.getDefault().getPerspectiveRegistry   ().findPerspectiveWithId("MyWork_mail.perspective");
            PerspectiveBarContributionItem item=new PerspectiveBarContributionItem(mailPerspective,activeWorkbenchWindow.getActivePage());
            barManager.addItem(item);
        }
}
2、在下拉框中(shortcut)昄��
public class UiPerspective implements IPerspectiveFactory
{
    public void createInitialLayout(IPageLayout layout){
....
        //增加透视�?br />         layout.addPerspectiveShortcut("net.sf.pim.plugin.UiPerspective");
        layout.addPerspectiveShortcut("MyWork_mail.perspective");
       }
}
十、控�?#8220;最�q�打开文档”的个�?br />        RCP中在�l�承ActionBarAdvisor的类中定�?
       private IContributionItem reOpenAction = ContributionItemFactory.REOPEN_EDITORS.create(window);
       然后在fillMenuBar(IMenuManager menuBar)�Ҏ��中添加上面的aciton
       �q�行�?#8220;最�q�打开的文�?#8221;只有4个，如果惌��己控�?#8220;最�q�打开的文�?#8221;的数量，则设�|�一下Workbench中的初始化首选项时RECENT_FILES的默认参数值如�Q?br /> WorkbenchPlugin.getDefault().getPreferenceStore().setDefault(IPreferenceConstants.RECENT_FILES,10);

十一、设�|�Eclipse RCP�E�序的外观和首选项
RCP应用�E�序的缺省外观是一个空白窗口，一般我们要通过一个WorkbenchAdvisor�c�d��界面�q�行定制�? WorkbenchAdvisor有很多回调方法，可以在preWindowOpen()�Ҏ��里设�|�菜单、工��h��、状态栏、进度栏、透视囑ֈ�换工��h��否可见，在fillActionBars()�Ҏ��里添加菜单和工具条项�Q�在getInitialWindowPerspectiveId()�Ҏ��里指定首选的透视图�?/font>

�~�省情况下，透视囑ֈ�换工具位于窗口左上角�Q�在Eclipse里可以通过Window->Preferences-> Workbench->Appearance改变它的位置�Q�那么怎样用程序控制它呢？有两个方法，�W�一个是使用如下代码讄�� IPreferenceStore中的变量�Q?/font>

IPreferenceStore apiStore = PrefUtil.getAPIPreferenceStore();
apiStore.setValue(IWorkbenchPreferenceConstants.DOCK_PERSPECTIVE_BAR, IWorkbenchPreferenceConstants.TOP_RIGHT);
另一个方法是在plugin所在目录徏一个名为plugin_customization.ini的文�Ӟ��里面写如下内容：

your.plugin.id/DOCK_PERSPECTIVE_BAR=topRight
其他与plugin相关的Preference值可以用同样�Ҏ��讄��?/font>

Update:在最新的Eclipse 3.1M5a版本中，对RCP应用�E�序菜单和工��h��的定制方法有所改变�Q�应该��用新加入的ActionBarAdvisor�c�L��完成此项工作�?/font>

十二、获得自己开发的plugin被安装的目录
/** *//**
     * @return 本插件的安装路径
     */
    public String getInstallDir() ...{
        if (installPath == null) ...{
            URL localUrl = null;
            try ...{
                localUrl = FileLocator.toFileURL(getDefault().getBundle()
                        .getEntry("/"));
                installPath = localUrl.getFile().substring(1);
            } catch (Exception e) ...{
                log(e);
            }
        }
        return installPath;
    }
