4 SWT编程须知
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 }
