是否可以将 QString 传递给 QMessageBox？
我正在开发 QT 应用程序，用户将在其中将其信息输入到多个 QLineEdit 中。然后他们将单击“提交”按钮。我希望出现一个 QMessageBox 询问他们是否要确认他们的信息（确定）或取消。我希望消息框显示他们输入的信息，以便他们可以检查信息是否准确。到目前为止，这是我的代码：
QString infoStr = (ui->lastEdit->text() + ", " + ui->firstEdit->text() + "\n" + ui->addressEdit->text() + "\n" + ui->cityEdit->text() + ", " + ui->stateBox->currentText() + " " + ui->zipEdit->text());
switch( QMessageBox::question(
this,
tr("Confirm"),
tr(infoStr&),
QMessageBox::Ok |
QMessageBox::Cancel ))
{
case QMessageBox::Ok:
QMessageBox::information(this, "OK", "Confirmed");
break;
case QMessageBox::Cancel:
//Cancel
break;
}
我是 QT 和 C++ 的新手。任何建议将不胜感激。
I'm working on QT application where the user will enter their information into several QLineEdits. They then will click son a Submit button. I would like a QMessageBox to appear asking if they would like to confirm their information(OK) or cancel. I want the messagebox to show the information they entered so that they can check to see if it's accurate. Here's my code so far:
QString infoStr = (ui->lastEdit->text() + ", " + ui->firstEdit->text() + "\n" + ui->addressEdit->text() + "\n" + ui->cityEdit->text() + ", " + ui->stateBox->currentText() + " " + ui->zipEdit->text());
switch( QMessageBox::question(
this,
tr("Confirm"),
tr(infoStr&),
QMessageBox::Ok |
QMessageBox::Cancel ))
{
case QMessageBox::Ok:
QMessageBox::information(this, "OK", "Confirmed");
break;
case QMessageBox::Cancel:
//Cancel
break;
}
I'm new to QT and C++. Anything suggestions would be greatly appreciated.

您应该阅读一本有关 C++ 的正确书籍。为此，您只需传递字符串作为参数，翻译可能不是您想要发生的情况，并且
&只是一个语法错误：You should read a proper book on C++. For this, you just need to pass the string as the argument, translating is probably not what you want to happen, and
&is just a syntax error:
