swt入门 --常用组件的使用

swt的常用组件button ,text ,combo,list ,还有一些容器类composite ,group，这里选择几个，列写简单的用法
不写解释了，因为代码很简单，而且代码上的注释足以说明.
1,combo 和text

package com.test;

import org.eclipse.swt.SWT;

import org.eclipse.swt.events.SelectionAdapter;

import org.eclipse.swt.events.SelectionEvent;

import org.eclipse.swt.widgets.Combo;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.List;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Text;

public class CTShow

{

private static List list;

private static Combo combo;

private static Text text;

public static void main(String[] args)

{

final Display display = Display.getDefault();

final Shell shell = new Shell();

shell.setSize(478, 120);

shell.setText("combo and text");

shell.open();

//构造text

text = new Text(shell, SWT.BORDER);

text.setBounds(160, 34, 281, 20);

//构造combo

combo = new Combo(shell, SWT.NONE);

combo.setItems(new String[]

{ "one", "two", "three", "four"});

combo.setData("one", "1");

combo.setData("two", "2");

combo.setData("three", "3");

combo.setData("four", "4");

combo.setBounds(28, 34, 102, 20);

//添加监听器

combo.addSelectionListener(new SelectionAdapter()

{

public void widgetSelected(SelectionEvent e)

{

String selText = combo.getText();

String selValue = (String)combo.getData(selText);

text.setText("text: " + selText + " value: " + selValue);

}});

shell.layout();

//消息循环

while (!shell.isDisposed())

{

if (!display.readAndDispatch())

display.sleep();

}

2,list、 button 、messagebox

package com.test;

import org.eclipse.jface.dialogs.MessageDialog;

import org.eclipse.swt.SWT;

import org.eclipse.swt.events.SelectionAdapter;

import org.eclipse.swt.events.SelectionEvent;

import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.List;

import org.eclipse.swt.widgets.Shell;

public class LBMShow

{

private static List list;

/** *//**

* Launch the application

* @param args

public static void main(String[] args)

{

final Display display = Display.getDefault();

final Shell shell = new Shell();

shell.setSize(192, 217);

shell.setText("list and button and messagebox");

shell.open();

//构造list

list = new List(shell, SWT.BORDER|SWT.MULTI|SWT.V_SCROLL);

list.setItems(new String[]

{ "语文", "数学", "英语", "物理", "化学"});

list.setData("化学", "HX");

list.setData("物理", "WL");

list.setData("语文", "YW");

list.setData("数学", "SX");

list.setData("英语", "YY");

list.setBounds(29, 25, 100, 75);

//构造button

final Button button = new Button(shell, SWT.NONE);

button.setText("提示");

button.setBounds(48, 121, 58, 22);

//添加监听器

button.addSelectionListener(new SelectionAdapter()

{

public void widgetSelected(SelectionEvent e)

{

for (String str : list.getSelection())

{

//messagebox提示

MessageDialog.openInformation(null, null, str);

}

});

shell.layout();

//消息循环

while (!shell.isDisposed())

{

if (!display.readAndDispatch())

display.sleep();

}

3,group组

package com.test;

import org.eclipse.swt.SWT;

import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Group;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Text;

public class GroupShow

{

private static Text text;

public static void main(String[] args)

{

final Display display = Display.getDefault();

Shell shell = new Shell();

shell.setText("group");

shell.open();

//构造group

final Group group = new Group(shell, SWT.NONE);

group.setText(" 组 ");

group.setBounds(41, 28, 143, 100);

//把按钮放在group中，注意new Button(group这里

final Button button = new Button(group, SWT.NONE);

button.setText("按钮");

button.setBounds(42, 59, 48, 22);

//构造text

text = new Text(group, SWT.BORDER);

text.setBounds(32, 28, 80, 25);

shell.layout();

while(!shell.isDisposed())

{

if (!display.readAndDispatch())

{

display.sleep();

}

Swt/Jface tableViewer入门教程一(显示tableViewer)

1，简单显示,表格的式样见注释中的内容

import org.eclipse.jface.viewers.TableViewer;

import org.eclipse.swt.SWT;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Table;

import org.eclipse.swt.widgets.TableColumn;

public class TestTableViewer

{

private static Table table;

/** *//**

* Launch the application

* @param args

public static void main(String[] args)

{

final Display display = Display.getDefault();

final Shell shell = new Shell();

shell.setSize(500, 375);

shell.setText("SWT Application");

//注意这里,SWT.NULTI代表可以选择多行,SWT.FULL_SELECTION代表可以整行选择,SWT.BORDER边框，SWT.V_SCROLL ,SWT.H_SCROLL滚动条

final TableViewer tableViewer = new TableViewer(shell, SWT.MULTI | SWT.FULL_SELECTION | SWT.BORDER|SWT.V_SCROLL|SWT.H_SCROLL);

table = tableViewer.getTable();

table.setLinesVisible(true);

table.setHeaderVisible(true);

table.setBounds(97, 79, 373, 154);

final TableColumn newColumnTableColumn = new TableColumn(table, SWT.NONE);

newColumnTableColumn.setWidth(39);

newColumnTableColumn.setText("ID");

final TableColumn newColumnTableColumn_1 = new TableColumn(table, SWT.NONE);

newColumnTableColumn_1.setWidth(85);

newColumnTableColumn_1.setText("姓名");

final TableColumn newColumnTableColumn_2 = new TableColumn(table, SWT.NONE);

newColumnTableColumn_2.setWidth(41);

newColumnTableColumn_2.setText("性别");

final TableColumn newColumnTableColumn_3 = new TableColumn(table, SWT.NONE);

newColumnTableColumn_3.setWidth(43);

newColumnTableColumn_3.setText("年龄");

final TableColumn newColumnTableColumn_4 = new TableColumn(table, SWT.NONE);

newColumnTableColumn_4.setWidth(126);

newColumnTableColumn_4.setText("创建日期");

shell.open();

while (!shell.isDisposed())

{

if (!display.readAndDispatch())

display.sleep();

}

2，加入布局
显示的效果不好，我们要加入布局，让view填充整个画面在shell.open()后加上
ok,效果达到
3，为TableViewer加上数据，光突突的样子不好看。这里是demo所以不再从数据库里边取数据了。自己构造一个List用来做数据。实际使用中也是这么使用，不过不同的是这里是随意构造的list，而显示实际使用中是从数据库取出数据构造list.
（1）构造一个people类，同时给People类提供一个构造假数据的方法getPeople()

import java.util.ArrayList;

import java.util.Date;

import java.util.List;

public class People

{

private Long id;

private String name;

private String sex;

private Integer age;

private Date createDate;

public People(Long id,String name,String sex,Integer age,Date createDate)

{

this.id = id;

this.name = name;

this.sex = sex;

this.age = age;

this.createDate = createDate;

}

public Integer getAge()

{

return age;

}

public void setAge(Integer age)

{

this.age = age;

}

public Date getCreateDate()

{

return createDate;

}

public void setCreateDate(Date createDate)

{

this.createDate = createDate;

}

public Long getId()

{

return id;

}

public void setId(Long id)

{

this.id = id;

}

public String getName()

{

return name;

}

public void setName(String name)

{

this.name = name;

}

public String getSex()

{

return sex;

}
