前几篇讲到了简单控件的使用，复杂控件使用原则上与简单控件差不多，不过数据的使用还有一些布局还有些额外的技巧。
成果展示：
这里介绍下Tab页，列表，以及树的使用。
Tab页
这个tab页仍然采用SWT控件的一贯作风，子页都以挂载的方式连接到Tab容器上，但是需要使用一个组个对象才能在里面放置内容，并不支持直接进行布局。
TabFolder tabFolder = new TabFolder(shell,SWT.BORDER); TabItem tabItem1 = new TabItem(tabFolder,SWT.NONE); tabItem1.setText("第一页"); Composite compsoite1 = new Composite(tabFolder,SWT.NONE); tabItem1.setControl(compsoite1); 这样再在Composite容器内放置其他的控件。
树形结构
而列表以及树的使用基本上差不多，树稍微复杂一点，有一个父亲孩子的概念，多使用几次就了解其中的关系技巧了。
tree = new Tree(treeGroup,SWT.SINGLE); tree.setLayoutData(new GridData(GridData.FILL_BOTH)); TreeItem stu1 = new TreeItem(tree,SWT.NONE); stu1.setText("xingoo"); { TreeItem info1 = new TreeItem(stu1,SWT.NONE); info1.setText("age:25"); TreeItem info2 = new TreeItem(stu1,SWT.NONE); info2.setText("tel:12345"); } TreeItem stu2 = new TreeItem(tree,SWT.NONE); stu2.setText("halo"); { TreeItem info3 = new TreeItem(stu2,SWT.NONE); info3.setText("age:25"); TreeItem info4 = new TreeItem(stu2,SWT.NONE); info4.setText("tel:67890"); } 表格
比较常用的一般就是列表，一般导向页，对话框也都是使用Table来制作。
table = new Table(tableGroup,SWT.SINGLE | SWT.BORDER | SWT.FULL_SELECTION); table.setHeaderVisible(true);//设置表头可见 table.setLinesVisible(true);//设置线条可见 table.setLayoutData(new GridData(GridData.FILL_BOTH)); TableColumn column1 = new TableColumn(table,SWT.NULL); column1.setText("Tree Item"); column1.pack(); column1.setWidth(150); TableColumn column2 = new TableColumn(table,SWT.NULL); column2.setText("Parent"); column2.pack(); column2.setWidth(150); TableItem item = new TableItem(table,SWT.NONE); item.setText(new String[]{“123”，“445”});
那么下面还是看一个搭配使用的例子
首先应用的是一个Tab容器，在第一页放置了一个树形控件，和一个列表控件。点击树形控件的节点，会在列表中添加相关的内容。
源码参考如下：
1 public void todo(Shell shell) { 2 TabFolder tabFolder = new TabFolder(shell,SWT.BORDER); 3 4 TabItem tabItem1 = new TabItem(tabFolder,SWT.NONE); 5 tabItem1.setText("第一页"); 6 7 Composite compsoite1 = new Composite(tabFolder,SWT.NONE); 8 tabItem1.setControl(compsoite1); 9 10 GridLayout layout = new GridLayout();11 layout.numColumns = 1;12 compsoite1.setLayout(layout);13 Group treeGroup = new Group(compsoite1,SWT.NONE);14 treeGroup.setText("Tree");15 GridData griddata = new GridData(GridData.FILL_BOTH);16 griddata.heightHint = 50;17 treeGroup.setLayoutData(griddata);18 treeGroup.setLayout(new GridLayout(1,false));19 {20 tree = new Tree(treeGroup,SWT.SINGLE);21 tree.setLayoutData(new GridData(GridData.FILL_BOTH));22 23 TreeItem stu1 = new TreeItem(tree,SWT.NONE);24 stu1.setText("xingoo");25 {26 TreeItem info1 = new TreeItem(stu1,SWT.NONE);27 info1.setText("age:25");28 29 TreeItem info2 = new TreeItem(stu1,SWT.NONE);30 info2.setText("tel:12345");31 }32 TreeItem stu2 = new TreeItem(tree,SWT.NONE);33 stu2.setText("halo");34 {35 TreeItem info3 = new TreeItem(stu2,SWT.NONE);36 info3.setText("age:25");37 38 TreeItem info4 = new TreeItem(stu2,SWT.NONE);39 info4.setText("tel:67890");40 }41 42 tree.addSelectionListener(new SelectionAdapter() {43 public void widgetSelected(SelectionEvent evt){44 TableItem item = new TableItem(table,SWT.NONE);45 item.setText(new String[]{tree.getSelection()[0].toString(),tree.getSelection()[0].getText()});46 }47 });48 }49 Group tableGroup = new Group(compsoite1,SWT.NONE);50 tableGroup.setText("Table");51 GridData gd = new GridData(GridData.FILL_BOTH);52 gd.heightHint = 20;53 tableGroup.setLayoutData(gd);54 tableGroup.setLayout(new GridLayout(1,false));55 { //创建一个单选的，有边界的，一行全选的表格56 table = new Table(tableGroup,SWT.SINGLE | SWT.BORDER | SWT.FULL_SELECTION);57 table.setHeaderVisible(true);//设置表头可见58 table.setLinesVisible(true);//设置线条可见59 table.setLayoutData(new GridData(GridData.FILL_BOTH));60 61 TableColumn column1 = new TableColumn(table,SWT.NULL);62 column1.setText("Tree Item");63 column1.pack();64 column1.setWidth(150);65 66 TableColumn column2 = new TableColumn(table,SWT.NULL);67 column2.setText("Parent");68 column2.pack();69 column2.setWidth(150); 70 }71 72 73 TabItem tabItem2 = new TabItem(tabFolder,SWT.NONE);74 tabItem2.setText("第二页");75 } 全部源码
