在我的應用程序中,需要在用戶提供輸入時經常顯示JOptionPane.showOptionDialog。使用自定義面板的JOptionPane.showOptionDialog無法正常工作
有時它不會顯示,並等待用戶輸入並掛起。
在這裏我附上了示例代碼來重現相同。
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顯示像
「測試的問題的消息索引= 0」,並點擊OK
「測試的問題的消息索引= 1」 並點擊OK
在一個隨機,不顯示JOptionPane.showOptionDialog。
請任何人都可以幫助我!提前致謝。
