在我的应用程序中,需要在用户提供输入时经常显示JOptionPane.showOptionDialog。使用自定义面板的JOptionPane.showOptionDialog无法正常工作
有时它不会显示,并等待用户输入并挂起。
在这里我附上了示例代码来重现相同。
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridBagLayout;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.JTextPane;
import javax.swing.ToolTipManager;
import javax.swing.text.BadLocationException;
import javax.swing.text.DefaultStyledDocument;
import javax.swing.text.Style;
import javax.swing.text.StyleConstants;
import javax.swing.text.StyleContext;
import javax.swing.text.StyledDocument;
public class TestJOptionPane {
public static void main(String[] args) {
for (int index = 0; index < 20; index++) {
String serverMessage = "Test question message index = "+index;
String hintText = "Test question hint index = "+index;
JPanel mainPanel = new JPanel(new BorderLayout(0,4));
JPanel answerPanel = new JPanel(new GridBagLayout());
StyleContext context = new StyleContext();
StyledDocument document = new DefaultStyledDocument(context);
Style style = context.getStyle(StyleContext.DEFAULT_STYLE);
StyleConstants.setFontFamily(style, "Dialog");
StyleConstants.setFontSize(style, 12);
StyleConstants.setBold(style, true);
try {
document.insertString(document.getLength(), serverMessage, style);
} catch (BadLocationException badLocationException) {
System.out.println(badLocationException.getMessage());
}
JTextPane questionTA = new JTextPane(document);
questionTA.setEditable(false);
questionTA.setOpaque(false);
final JTextField answerField = new JTextField();
answerField.setPreferredSize(new Dimension(410,23));
answerField.requestFocus();
JLabel hint = new JLabel();
ToolTipManager.sharedInstance().setDismissDelay(10000);
hint.setText("Hint");
// hint.setIcon(Utility.getIcon("HintQuestion.png"));
answerPanel.add(answerField);
answerPanel.add(new JPanel().add(hint));
answerPanel.setPreferredSize(new Dimension(450, 30));
mainPanel.add(questionTA,BorderLayout.NORTH);
mainPanel.add(answerPanel,BorderLayout.SOUTH);
hint.setToolTipText(hintText);
String[] options = {"OK"};
JOptionPane.showOptionDialog(null, mainPanel, "Test showOptionDialog", JOptionPane.OK_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[0]);
}
}
}
的O/P显示像
“测试的问题的消息索引= 0”,并点击OK
“测试的问题的消息索引= 1” 并点击OK
在一个随机,不显示JOptionPane.showOptionDialog。
请任何人都可以帮助我!提前致谢。
