swt 菜单栏的编写

例2—1非常简单的shell

package pr;

import org.eclipse.swt.widgets.*;

public classSimpleShell {

    SimpleShell(){

        Displayd=newDisplay();//创建Display这个class的实例

        Shells=newShell(d);//将Display的实例传给shell的够着来创建Shell的实例

        s.setSize(500,500);//设置窗口的大小

        s.open();

        while(!s.isDisposed()){

            if(!d.readAndDispatch())

                d.sleep();

            }

        d.dispose();

        }

     

    public static void main(String[] args) {

        SimpleShellss=newSimpleShell();

    }

}

例2-3设定shell样式

package pr;

import org.eclipse.swt.widgets.*;

import org.eclipse.swt.*;

public classShellStylesExample {

    ShellStylesExample(){

        Displayd=newDisplay();

        Shells=newShell(d,SWT.CLOSE|SWT.RESIZE );//创建窗口的样式有关闭按钮且可以调整大小

        s.setSize(300,300);

        s.open();

        while(!s.isDisposed()){

            if(!d.readAndDispatch())

                d.sleep();

            }

        d.dispose();

        }  

    public static void main(String[] args) {

        ShellStylesExampless=newShellStylesExample();

    }

}

例2-5创建一个可以开启在parent shell范围中的shell的instance

package pr;

import org.eclipse.swt.widgets.*;

public classChildShell {

    ChildShell(Shellparent){

        Shellchild=newShell(parent);//创建一个可以开启在parent shell范围中的shell的实例

        child.setSize(200,200);//设置子窗口的大小

        child.open();

    }

     

}

例2-6：在parent shell之内开启childshell

package pr;

import org.eclipse.swt.widgets.*;

public classChildShellExample {

Display d=new Display();

ChildShellExample (){

    Shells=newShell(d);

    s.setSize(500,500);

    s.open();

    ChildShellcs=newChildShell(s);//在parent shell之内开启childshell

    while(!s.isDisposed()){

        if(!d.readAndDispatch())

            d.sleep();

    ChildShellExample1(){

        Shells=newShell(d);

        s.setSize(500,500);

        s.open();

        ChildShellcs1=newChildShell(s);

        ChildShellcs2=newChildShell(s);

        ChildShellcs3=newChildShell(s);//创建多个子窗口

        while(!s.isDisposed()){

            if(!d.readAndDispatch())

                d.sleep();

            }

        d.dispose();

        }  

    public static void main(String[] args) {

        ChildShellExample1ss=newChildShellExample1();

    }

    }

例2-9：application modal 的dialog

package pr;

import org.eclipse.swt.widgets.*;

import org.eclipse.swt.SWT;

public classDialogExample extends Dialog{

DialogExample(Shell parent)

{

    super(parent);

}  

    public String open()

    {

        Shellparent=getParent();

        Shelldialog=newShell(parent,

                SWT.DIALOG_TRIM|SWT.APPLICATION_MODAL);//创建一个application modal的dialog

        dialog.setSize(100,100);

        dialog.setText("A dialog");//设置标题

        dialog.open();

        Displaydisplay=parent.getDisplay();

        while(!dialog.isDisposed())

        {if(!display.readAndDispatch())

            display.sleep();

        }

        return"After Dialog";

    }

}

例2-10：开启dialog

package pr;

import org.eclipse.swt.widgets.*;

public classShellDialogExample {

    ShellDialogExample()

    {

        Displayd=newDisplay();

        Shells=newShell(d);

        s.setSize(300,300);

        s.open();

        DialogExamplede=newDialogExample(s);//用parent shell开启dialog

        Stringresult=de.open();

        System.out.println(result);

        while(!s.isDisposed()){

            if(!d.readAndDispatch())

                d.sleep();

            }

        d.dispose();

        }  

    public static void main(String[] args) {

        ShellDialogExampless=newShellDialogExample();

    }

    }

例 2-11:设定shell的icon

package pr;

import org.eclipse.swt.widgets.*;

import org.eclipse.swt.graphics.Image;

public classProfessionalShell {

     ProfessionalShell(){

         

         Display d=new Display();

            Shells=newShell(d);

            s.setSize(500,500);

            s.setImage(new Image(d,"f:\\a.jpg"));//设置窗口的图标

            s.setText("A Shell Example");

            s.open();

            while(!s.isDisposed()){

                if(!d.readAndDispatch())

                    d.sleep();

                }

            d.dispose();

            }      

        public static void main(String[] args) {

            ProfessionalShellss=newProfessionalShell();

        }

}

     s.setImage(newImage(d,"f:\\a.jpg"));

        s.setText("A Shell Menu Example");

        Menum=newMenu(s,SWT.BAR);//创建menu的instance

        s.setMenuBar(m);

        s.open();

        while(!s.isDisposed()){

            if(!d.readAndDispatch())

                d.sleep();

         s.setImage(newImage(d,"f:\\a.jpg"));

            s.setText("A Shell Menu Example");

            Menum=newMenu(s,SWT.BAR);//设置菜单

            MenuItemfile=newMenuItem(m,SWT.CASCADE);//建立File菜单且是层叠样式的菜单

            file.setText("File");

            Menufilemenu=newMenu(s,SWT.DROP_DOWN);//下拉式样式的菜单

            file.setMenu(filemenu);

            MenuItemopenItem=newMenuItem(filemenu,SWT.PUSH);//file菜单下的次级选项Open

            openItem.setText("Open");

            MenuItemexitItem=newMenuItem(filemenu,SWT.PUSH);//file菜单下的次级选项Exit

            exitItem.setText("Exit");
