Equinox下的WEB随想

从目前的��势来看�Q�OSGI在��Y件行业的应用相当被看好，ECLIPSE,WAS也全面采用OSGI规范了，�׃��eclipse自��n在采用OSGI之前有一套自恰的plugin机制�Q�而这�U�几乎具备无限扩充的plugin机制打开了一个巨大的plugin市场�Q�再加上OpenSource的东风，使得eclipse几乎一�l�Java的IDE市场�?br /> �?.0eclipse全面采用OSGI开始，便对OSGI多了一份研�IӞ��在以eclipse��景的桌面软�g开发领域，osgi如鱼得水�Q�但我更多的是在做Java的server端开发，很想能够看到web领域能从osgi/Equinox中得��C��些灵感，很希望，那灵�zȝ��plugin/bundle机制能发挥在web的前后端开发中�Q�之前在TSS上有人做了一个自�U�CؓRSP�Q�与RCP相响应）的DEMO�Q�展�C�Z��如何在Web��面中做��C��重启服务器来实现��面数据的动态组装及服务��h��。我们都知道在eclipse的插件开发中�Q�我们可以单独开发一个viewpart或者菜单来插入到现成的IDE中而保持独立性，如果�q�种�Ҏ��能在WEB中实现的话，那是相当的诱人的�Q�现在Equinox已经实现的OSGI 的大部分规范�Q�也提供了对serlvet及jsp的支持，但仍不够方便�Q�希望在不久以后能看�q�方面的�q�展�?br />

SWT中的Sytem Tray相关处理

SWT已经提供了对部分�q�_��Q�比如window�Q�上的系�l�托盘的支持。但支持得还不够好，我最�q�需要在一个聊天工具实现Balloon效果(�_�附于系�l�托盘上的一个消息气泡效果，在IM软�g中普遍被支持)�Q�查一下SWT API,到目前�ؓ上�ƈ没有提供支持。但一个好消息是在月底交要出来�?.2M6中，��对部分API做调��_��增加对Balloon的支持�?br />

Milestone Plan 3.2 M6 March 31 , 2006

Implement custom draw for table and tree
Implement native drag source effects for cursor
Implement ImageTransfer support
Implement Balloon tooltips
Implement Accessibility on Mac OS X

�q�儿是EclipseZone上的一个针对这一效果的文章：TrayIcons and ToolTips http://www.eclipsezone.com/eclipse/forums/t66093.rhtml

甚至在官方网站上�Q�已�l�提供了�q�一个API的Snippet

    Display display = new Display();
    Shell shell = new Shell(display);
    Image image = null;
    final ToolTip tip = new ToolTip(shell, SWT.BALLOON | SWT.ICON_INFORMATION);
    tip.setMessage("Here is message for the user. When the message is too long it wraps. I should say something cool but nothing comes to my mind.");
    Tray tray = display.getSystemTray();
    if (tray != null) {
        TrayItem item = new TrayItem(tray, SWT.NONE);
        image = new Image(display, Snippet225.class.getResourceAsStream("eclipse.png"));
        item.setImage(image);
        tip.setText("Notification from a tray item");
        item.setToolTip(tip);
    } else {
        tip.setText("Notification from anywhere");
        tip.setLocation(400, 400);
    }
    Button button = new Button (shell, SWT.PUSH);
    button.setText("Press for balloon tip");
    button.addListener(SWT.Selection, new Listener() {
        public void handleEvent(Event event) {
            tip.setVisible(true);
        }
    });
    button.pack();
    shell.setBounds(50, 50, 300, 200);
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch()) display.sleep();
    }
    if (image != null) image.dispose();
    display.dispose();
}
}

除此之外�Q�也有其它的�W�三方API实现了此一效果。是�?a >www.novocode.com提供的BalloonWindow。其API可在上述的网站中获得�?/p>
