在 C++ 中 BoolResult 被强制转换为指针：

bool ok;
int i = QInputDialog::getInt(this, tr("QInputDialog::getInteger()"),
                             tr("Percentage:"), 25, 0, 100, 1, &ok);
if (ok)
    integerLabel->setText(tr("%1%").arg(i));

如何在 pyQt/pythonQt 中检索“ok”布尔值？

它尝试了以下不起作用：

from PythonQt.QtGui import QInputDialog, QWidget
from PythonQt.QtCore import Qt, QTimer
from PythonQt import BoolResult
...
x = QWidget()
x.setAttribute(Qt.WA_DeleteOnClose)
ok = BoolResult()
i = QInputDialog.getInt(x, "test", "hallo", 1000, None, None, None, ok)
print("ok:", ok)
print("i:", i)
print("i:", i)

这导致

您的问题是您必须分配适当的值并且您不应该使用None，例如，如果我们看到 Qt 的文档：

int QInputDialog::getInt(QWidget *parent, const QString &title, const QString &label, int value = 0, int min = -2147483647, int max = 2147483647, int step = 1, bool *ok = Q_NULLPTR, Qt::WindowFlags flags = Qt::WindowFlags())

所以一个可能的解决方案是复制这些值：

ok = BoolResult()
i = QInputDialog.getInt(push1, "test", "hallo", 1000, -2147483647, 2147483647, 1, ok)
print("ok:", ok)
print("i:", i)
