qt - 如何将默认文本填充到 QInputDialog

Question

我正在尝试将默认文本填充到 QInputDialog 的 LineEdit 字段中(例如填充旧值以重命名)。这是代码:

  bool dialogResult;
  QInputDialog *renameDialog = new QInputDialog();
  renameDialog->setTextValue("Test"); // has no effect
  QString result = renameDialog->getText(0, "Rename Label", "New name:", QLineEdit::Normal,
                                         "", &dialogResult);
  if(result.length() > 0 && dialogResult) setText(result);

如何为 InputDialog 设置一个值以使其默认填充？

Answer 1

您需要将默认文本作为第五个参数传递:

QString result = renameDialog->getText(0, "Rename Label", "New name:", QLineEdit::Normal,
                                       "DEFAULT TEXT", &dialogResult);

另见 QInputDialog::getText() :

... text is the default text which is placed in the line edit ...
