强！简洁！SWT实现任务栏图标（系统托盘），带菜单和ToolTip

[zclgod]

今天在网上看到一个任务栏的例子。

简洁！SWT实现任务栏图标，带菜单和ToolTip。
不知道哪位再把她改进改进，让任务栏不显示，只要那个托盘的。







import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.widgets.Listener;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Tray;
import org.eclipse.swt.widgets.TrayItem;

public class Snippet143 {

public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
Image image = new Image(display, 16, 16);
final Tray tray = display.getSystemTray();
if (tray == null) {
System.out.println("The system tray is not available");
} else {
final TrayItem item = new TrayItem(tray, SWT.NONE);
item.setToolTipText("SWT TrayItem");
item.addListener(SWT.Show, new Listener() {
public void handleEvent(Event event) {
System.out.println("show");
}
});
item.addListener(SWT.Hide, new Listener() {
public void handleEvent(Event event) {
System.out.println("hide");
}
});
item.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
System.out.println("selection");
}
});
item.addListener(SWT.DefaultSelection, new Listener() {
public void handleEvent(Event event) {
System.out.println("default selection");
}
});
final Menu menu = new Menu(shell, SWT.POP_UP);
for (int i = 0; i < 8; i++) {
MenuItem mi = new MenuItem(menu, SWT.PUSH);
mi.setText("Item" + i);
}
item.addListener(SWT.MenuDetect, new Listener() {
public void handleEvent(Event event) {
menu.setVisible(true);
}
});
item.setImage(image);
}
shell.setBounds(50, 50, 300, 200);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
image.dispose();
display.dispose();
}
}

os这个东东好强好

刚才还弄出来一个不能改变位置的窗口

谁有OS的相关资料啊

另外
怎么提交到F/Q啊
感觉这个例子很多人都需要啊

[ghostvalley]

哈哈，看来最后的答案要归我了

在
Display display = new Display();
Shell shell = new Shell(display);
的后面加上两条语句：
final int hWnd = shell.handle;
OS.SetWindowLong(hWnd,OS.GWL_EXSTYLE,OS.WS_EX_TOOLWINDOW);

这样窗体显示的时候，任务栏就不显示，学过WIN32 API windows编程的朋友应该看得懂

C500 CPU+128M RAM同时运行OPERA＋ECLIPSE3.1.2+VC6+MSDN的速度简直能让人自杀

[zclgod]

怎么提交FAQ啊？

[ghostvalley]

忘说了，OS这个类在 org.eclipse.swt.internal.win32包里面

[YuLimin]

不错的贴子，结贴后右上角有个提交FAQ的链接啊。

那是因为你的电脑没有装SWT包

我也是JAVA初学者，我的eclipse3.1.2, 怎么无法导入这些包呢?

在任务栏里，右键的时候会有 Item0---Item7，这几个是做什么用的 啊！！

[zzhzzh204553]

要添加org.eclipse.swt
在添加库时,选择swt库

[洋溢2020]

get it

[ztjxcsdn]

不错,挺有用的!谢
