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

packagecom.test;

importorg.eclipse.swt.SWT;
importorg.eclipse.swt.events.SelectionAdapter;
importorg.eclipse.swt.events.SelectionEvent;
importorg.eclipse.swt.widgets.Combo;
importorg.eclipse.swt.widgets.Display;
importorg.eclipse.swt.widgets.List;
importorg.eclipse.swt.widgets.Shell;
importorg.eclipse.swt.widgets.Text;

publicclassCTShow{

privatestaticListlist;
privatestaticCombocombo;
privatestaticTexttext;
publicstaticvoidmain(String[]args){
finalDisplaydisplay=Display.getDefault();
finalShellshell=newShell();
shell.setSize(478,120);
shell.setText("comboandtext");
shell.open();
//构造text
text=newText(shell,SWT.BORDER);
text.setBounds(160,34,281,20);
//构造combo
combo=newCombo(shell,SWT.NONE);
combo.setItems(newString[]{"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(newSelectionAdapter(){
publicvoidwidgetSelected(SelectionEvente){
StringselText=combo.getText();
StringselValue=(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

packagecom.test;

importorg.eclipse.jface.dialogs.MessageDialog;
importorg.eclipse.swt.SWT;
importorg.eclipse.swt.events.SelectionAdapter;
importorg.eclipse.swt.events.SelectionEvent;
importorg.eclipse.swt.widgets.Button;
importorg.eclipse.swt.widgets.Display;
importorg.eclipse.swt.widgets.List;
importorg.eclipse.swt.widgets.Shell;

publicclassLBMShow{

privatestaticListlist;
/***//**
*Launchtheapplication
*@paramargs
*/
publicstaticvoidmain(String[]args){
finalDisplaydisplay=Display.getDefault();
finalShellshell=newShell();
shell.setSize(192,217);
shell.setText("listandbuttonandmessagebox");
//

shell.open();
//构造list
list=newList(shell,SWT.BORDER|SWT.MULTI|SWT.V_SCROLL);
list.setItems(newString[]{"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
finalButtonbutton=newButton(shell,SWT.NONE);
button.setText("提示");
button.setBounds(48,121,58,22);
//添加监听器
button.addSelectionListener(newSelectionAdapter(){
publicvoidwidgetSelected(SelectionEvente){
for(Stringstr: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

packagecom.test;

importorg.eclipse.swt.SWT;
importorg.eclipse.swt.widgets.Button;
importorg.eclipse.swt.widgets.Display;
importorg.eclipse.swt.widgets.Group;
importorg.eclipse.swt.widgets.Shell;
importorg.eclipse.swt.widgets.Text;

publicclassGroupShow{
privatestaticTexttext;
publicstaticvoidmain(String[]args){
finalDisplaydisplay=Display.getDefault();
Shellshell=newShell();
shell.setText("group");
shell.open();
//构造group
finalGroupgroup=newGroup(shell,SWT.NONE);
group.setText("组");
group.setBounds(41,28,143,100);
//把按钮放在group中，注意newButton(group这里
finalButtonbutton=newButton(group,SWT.NONE);
button.setText("按钮");
button.setBounds(42,59,48,22);
//构造text
text=newText(group,SWT.BORDER);
text.setBounds(32,28,80,25);
//
shell.layout();
while(!shell.isDisposed()){
if(!display.readAndDispatch()){
display.sleep();
}
}
}
}
