swt中的对话框

对话框主要有以下六种：

1.MessageBox，消息对话框

只有OK按钮的：
                MessageBox messageBox = new MessageBox(shell, SWT.ICON_WARNING
                        | SWT.OK);
                messageBox.setText("title");
                messageBox.setMessage("这是一个测试");
                messageBox.open();

有是和否按钮的：

                MessageBox messageBox = new MessageBox(shell,
                        SWT.ICON_INFORMATION | SWT.YES | SWT.NO);
                messageBox.setText("title");
                messageBox.setMessage("这是一个测试");
                int rc = messageBox.open();
                if (rc == SWT.YES) {
                    text.setText("你点击了YES");
                } else if (rc == SWT.NO) {
                    text.setText("你点击了NO");
                }


 

2.DirectoryDialog，文件夹选择框

                DirectoryDialog dlg = new DirectoryDialog(shell);
                dlg.setText("SWT’s DirectoryDialog");
                dlg.setMessage("Select a directory");
                String directoryName = dlg.open();
                if (directoryName != null) {
                    text.setText(directoryName);
                }


 

3.FileDialog，文件选择对话框
                FileDialog dlg = new FileDialog(shell, SWT.OPEN);
                dlg.setFilterExtensions(new String[] { "*.doc;*.xls;*.ppt" });
                String fileName = dlg.open();
                if (fileName != null) {
                    text.setText(fileName);
                }

 

4.FontDialog，字体选择对话框

                FontDialog dlg = new FontDialog(shell);
                FontData fontData = dlg.open();
                if (fontData != null) {
                    Font font = new Font(shell.getDisplay(), fontData);
                    Color color = new Color(shell.getDisplay(), dlg.getRGB());
                    text.setFont(font);
                    text.setForeground(color);
                }


 

5.ColorDialog，颜色选择对话框
                ColorDialog dlg = new ColorDialog(shell);
                RGB rgb = dlg.open();
                if (rgb != null) {
                    Color color = new Color(shell.getDisplay(), rgb);
                    text.setForeground(color);
                }

 

6.PrintDialog，打印对话框

这个稍复杂

 

通过扩展Dialog类，还可以自定义对话框
