eclipse插件開發筆記

一個TableCombo簡單示例，部門經理幫咱下的源碼，然後咱自己發佈了一下，可以用了。關於插件開發就不多說了，直接上例子（將本案例代碼加到可以運行的eclipse插件項目即可）。

1、需要的東西

org.eclipse.nebula.widgets.tablecombo_1.0.0.201110222059.jar，將該包置於eclipse文件下的plugins中

這個是nebula項目中案例，現在好像木有jar包可以下，所以就將源碼下下來自己打包發佈，以供使用（後面一長串數字是eclipse打包的時候自己生成的，無影響使用，jar包及源碼稍後提供下載）。

2、將該jar包作爲插件添加到eclipse插件項目中，具體步驟如下：

（1）打開plugin.xml，選擇Dependencies頁面，選擇Required Plug-ins 的“Add...”按鈕，在彈出的對話框中輸入“org.eclipse.nebula.widget.tablecombo”，選中插件雙擊即可完成添加

（2）示例代碼

import java.util.ArrayList;
import java.util.List;

import org.eclipse.nebula.widgets.tablecombo.TableCombo;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.TableEditor;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableItem;
import org.eclipse.ui.forms.IManagedForm;
import org.eclipse.ui.forms.editor.FormEditor;
import org.eclipse.ui.forms.editor.FormPage;
import org.eclipse.ui.forms.widgets.ScrolledForm;

import com.plugindev.addressbook.bean.Model;
import com.plugindev.addressbook.util.ImageCache;
import com.plugindev.addressbook.util.ImageKeys;

public class OtherPage extends FormPage {

 private static List modelList;

 private int index;

 public OtherPage(FormEditor editor) {
  super(editor, "otherpage", "otherpage");

 }

 protected void createFormContent(final IManagedForm imanagedForm) {
  final ScrolledForm form = imanagedForm.getForm();
  form.setText("otherpage");
  form.setBackgroundImage(ImageCache.getInstance().getImage(
    ImageKeys.getImageDescriptor(ImageKeys.IMG_FORM_BG)));

  Composite composite = form.getBody();
  GridLayout layout = new GridLayout();
  layout.numColumns = 1;
  composite.setLayout(layout);
  GridData gd = new GridData();
  gd.horizontalSpan = 1;
  composite.setLayoutData(gd);

  TableCombo tc = new TableCombo(composite, SWT.BORDER | SWT.READ_ONLY);
  tc.setLayoutData(new GridData(150, SWT.DEFAULT));

  modelList = loadModel();

  // tell the TableCombo that I want 3 columns autosized with the
  // following column headers.
  tc.defineColumns(new String[] { "", "Id", "Description" }, new int[] {
    30, SWT.DEFAULT, SWT.DEFAULT });

  // 取第三列的值
  tc.setDisplayColumnIndex(2);

  // 顯示錶頭
  tc.setShowTableHeader(true);

  // 加載數據
  loadThreeColumnDataset(tc.getTable());

 }

 /**
  * load a list of rows with 3 columns
  *
  * @return
  */
 private void loadThreeColumnDataset(final Table table) {
  List<TableItem> rowList = new ArrayList<TableItem>();

  int total = (modelList == null ? 0 : modelList.size());

  TableEditor[] editors = new TableEditor[total];

  final Button[] buttons = new Button[total];
  table.setLinesVisible(true);
  for (index = 0; index < total; index++) {

   TableItem ti = new TableItem(table, SWT.NONE);
   editors[index] = new TableEditor(table);
   buttons[index] = new Button(table, SWT.CHECK);
   buttons[index].setBackground(new Color(Display.getDefault(), 255,
     255, 255));
   editors[index].grabHorizontal = true;
   editors[index].setEditor(buttons[index], ti, 0);

   Model model = (Model) modelList.get(index);
   ti.setText(new String[] { "", model.getId() + "",
     model.getDescription() });
   // rowList.add(ti);
  }

  // return rowList;
 }

 /**
  * load the Model data.
  *
  * @return
  */
 @SuppressWarnings("unchecked")
 private static List loadModel() {
  List items = new ArrayList();
  items.add(new Model(1, "One"));
  items.add(new Model(2, "Two"));
  items.add(new Model(3, "Three"));
  items.add(new Model(4, "Four"));
  items.add(new Model(5, "Five"));
  items.add(new Model(6, "Six"));

  return items;
 }

}

注意：需要建立Model實體

屬性自己定，只要和上面代碼中model.getXXX()匹配就行

public class Model {

 private int id;

 private String description;

 public int getId() {
  return id;
 }

 public void setId(int id) {
  this.id = id;
 }

 public String getDescription() {
  return description;
 }

 public void setDescription(String description) {
  this.description = description;
 }

 public Model(int id, String description) {
  this.id = id;
  this.description = description;
 }

}

（3）效果如圖
