在Pythonqt中使用Boolresult

Use BoolResult in pythonQt

本文关键字：Boolresult Pythonqt      更新时间：2023-10-16

在C 布尔苏尔特中被铸成指针：

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));

一个人如何在pyqt/pythonqt中检索" ok"布尔？

它尝试了以下几个行不通的：

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

ValueError: Could not find matching overload for given arguments:

 The following slots are available:
static getInt(QWidget parent, QString title, QString label, int value, int minValue, int maxValue, int step, PythonQt.BoolResult ok, Qt::WindowFlags flags) -> int
static getInt(QWidget parent, QString title, QString label, int value, int minValue, int maxValue, int step, PythonQt.BoolResult ok) -> int
static getInt(QWidget parent, QString title, QString label, int value, int minValue, int maxValue, int step) -> int
static getInt(QWidget parent, QString title, QString label, int value, int minValue, int maxValue) -> int
static getInt(QWidget parent, QString title, QString label, int value, int minValue) -> int
static getInt(QWidget parent, QString title, QString label, int value) -> int
static getInt(QWidget parent, QString title, QString label) -> int

在您的情况下的问题是您必须分配适当的值，并且不应使用None，例如，如果我们看到QT的文档：

int Qinputdialog :: getint(qwidget *parent，const qString＆const qString＆const qString＆amp＆amp; label，int value = 0，int min = -2147483647，int = -2147483647，int max = 2147483647，int int step = 1，布尔*ok = q_nullptr，qt :: windowflags flags = qt :: windowflags(((

因此，一个可能的解决方案是复制以下值：

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