Basically, that is the way of it. As you can't directly overwrite the paint
mechanism of the title bar and its buttons in Java (or can you?), you have
to use a stripped down window without all these stuff and draw everything
yourself. BTW, you can use the same technique to draw custom widgets (or
components, as they're called in Java), though you might want to use a
custom look-and-feel instead of reinventing the wheel.

Posted by: elysium922 Posted on: 2005-01-20 17:17 Sorry, I reached this link from the "latest posts" list and I thought your question is about Swing. Anyway, I don't think you can do that in SWT either, although I'm not completely sure about it. Anyway, take a look at lumaQQ (is this spelling correct?), which is a Java implementation of QQ, using SWT as its UI library.

你可以创建一个shell使用NO_TRIM属性，这样，你就获得了一个没有titlebar的窗口，然后用layout控制你的button所在的位置即可。在这种情况下的shell你可以通过api控制shell的最大化，最小化，关闭等，至于这些button的美化，你怎么做都可以，事件的监听就跟你自己说的一样。
如：
final Shell mainWin = new Shell(display,SWT.NO_TRIM);
shell.setLayout(new GridLayout());
Button maxButton = new Button(mainWin,SWT.NONE);
Button closeButton = new Button(mainWin,SWT.NONE);
closeButton.addSelectionListener(new SelectionListener() {
public void widgetSelected(SelectionEvent event) {
mainWin.dispose();
}
});

Posted by: cnfree Posted on: 2005-02-17 22:05 SWT.NO_TRIM,采用这个属性之后,窗口最大化最好不要使用setMaximized()方法，否则会覆盖到整个窗口，只能采用setSize来控制，Window操作系统底部一行高度为28。最后改变布局只用重新调用layout方法就可以了
