Question

我目前正在学习eclipse插件的工作原理。我想在一个视图中得到一个表，我一直在搞乱示例视图插件一段时间，但我仍然无法让它工作。以下是示例视图插件中的代码段：

package com.example.helloworld2.views;


import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.part.*;
import org.eclipse.jface.viewers.*;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.layout.GridData;
import org.eclipse.jface.action.*;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.ui.*;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.SWT;

public class SampleView extends ViewPart {

    /**
     * The ID of the view as specified by the extension.
     */
    public static final String ID = "com.example.helloworld2.views.SampleView";

    private TableViewer viewer;
    private Action action1;
    private Action action2;
    private Action doubleClickAction;

    /*
     * The content provider class is responsible for
     * providing objects to the view. It can wrap
     * existing objects in adapters or simply return
     * objects as-is. These objects may be sensitive
     * to the current input of the view, or ignore
     * it and always show the same content 
     * (like Task List, for example).
     */

    class ViewContentProvider implements IStructuredContentProvider {
        public void inputChanged(Viewer v, Object oldInput, Object newInput) {
        }
        public void dispose() {
        }
        public Object[] getElements(Object parent) {
            return new String[] { "Onsdfsde", "Twosdfsd", "Threesdf" };
        }
    }
    class ViewLabelProvider extends LabelProvider implements ITableLabelProvider {
        public String getColumnText(Object obj, int index) {
            return getText(obj);
        }
        public Image getColumnImage(Object obj, int index) {
            return getImage(obj);
        }
        public Image getImage(Object obj) {
            return PlatformUI.getWorkbench().
                    getSharedImages().getImage(ISharedImages.IMG_OBJ_ELEMENT);
        }
    }
    class NameSorter extends ViewerSorter {
    }

    /**
     * The constructor.
     */
    public SampleView() {
    }

    /**
     * This is a callback that will allow us
     * to create the viewer and initialize it.
     */
    public void createPartControl(Composite parent) {
        viewer = new TableViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL);
        viewer.setContentProvider(new ViewContentProvider());
        viewer.setLabelProvider(new ViewLabelProvider());
        viewer.setSorter(new NameSorter());
        viewer.setInput(getViewSite());

        // Create the help context id for the viewer's control
        PlatformUI.getWorkbench().getHelpSystem().setHelp(viewer.getControl(), "com.example.helloworld2.viewer");

    }

...
}

视图内容提供者似乎负责将内容放入视图中，但我究竟会如何插入表？理想情况下，我最终希望插入一个复杂的树表：

但是，如果有人能用我能读到的类似甚至某种资源直接指出我，那就太棒了。

Answer 1

您已经在createPartControl（）中插入一个表作为“new TableViewer（）”调用的一部分。要插入不同的小部件，您可以更改createPartControl（）以执行不同的操作，例如使用TreeTableViewer。

Answer 2

Table table = viewer.getTable();

根据我从你的问题推断，我认为上面的代码应该做你想要的。
