在pythonQt中使用BoolResult

C ++中的

BoolResult被转换为指针:

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));

如何检索" ok" bool in pyQt / pythonQt?

尝试了下面的工作:

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)

导致

答案 0 :(得分:1)

您的案例中的问题是您必须指定适当的值,而不应使用None,例如,如果我们看到Qt的docs

  

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)
