JOptionPane是/否选项确认对话框问题
JOptionPane是/否选项确认对话框问题
提问于 2012-01-01 00:14:36
我已经创建了一个JOptionPane，它只有两个按钮YES_NO_OPTION。
在JOptionPane.showConfirmDialog弹出后，我想单击YES BUTTON继续打开JFileChooser，如果我单击了NO BUTTON，它应该会取消操作。
这看起来很简单，但我不确定我的错误在哪里。
代码片段：
if (textArea.getLineCount() >= 1) { //The condition to show the dialog if there is text inside the textArea
int dialogButton = JOptionPane.YES_NO_OPTION;
JOptionPane.showConfirmDialog (null, "Would You Like to Save your Previous Note First?","Warning",dialogButton);
if (dialogButton == JOptionPane.YES_OPTION) { //The ISSUE is here
JFileChooser saveFile = new JFileChooser();
int saveOption = saveFile.showSaveDialog(frame);
if(saveOption == JFileChooser.APPROVE_OPTION) {
try {
BufferedWriter fileWriter = new BufferedWriter(new FileWriter(saveFile.getSelectedFile().getPath()));
fileWriter.write(textArea.getText());
fileWriter.close();
} catch(Exception ex) {
}

尝尝这个,
int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
System.out.println("Yes option");
} else {
System.out.println("No Option");

int opcion = JOptionPane.showConfirmDialog(null, "Realmente deseas salir?", "Aviso", JOptionPane.YES_NO_OPTION);
if (opcion == 0) { //The ISSUE is here
System.out.print("si");
} else {
System.out.print("no");
