当我显示带有此代码的messagebox时Python 如何修改pyqt5 messagebox以永久显示按钮上的快捷键,python,pyqt,pyqt5,Python,Pyqt,Pyqt5,当我显示带有此代码的messagebox时 def exitActionProcedure(self, ask): """ # Method: exitActionProcedure. # Description: The procedure for closing the application # and all the opened files. """ if ask is True

buttonReply = QMessageBox.question(
None, 'Exit', "Quit Program?",

这是显示的
按alt键时,按钮中会显示下划线/快捷键
像这样
如何在不按alt键的情况下显示下划线/快捷键?修复程序是对pyqt5 5.15.0的升级 感谢eyllanesc指出这一点。你可以试试。在我的Windows计算机上,只有Fusion样式显示下划线 我从菜单中的表单…预览中获得了Qt Designer的样式名称。Linux或Mac可能有不同的可用样式 守则:
from PyQt5 import uic, QtCore, Qt
from PyQt5.QtWidgets import (QApplication, QMainWindow, QMessageBox,
QStyleFactory)
form_class = uic.loadUiType('qstyle.ui')[0]
class MainWindow(QMainWindow, form_class):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent=parent)
self.setupUi(self)
self.setWindowTitle("QMessageBox Style Test")
verString = 'PyQt version: ' + Qt.PYQT_VERSION_STR + '\n'
verString += 'Qt version: ' + QtCore.qVersion()
self.lblVersion.setText(verString)
@QtCore.pyqtSlot(int)
def on_bgrpRadio_buttonClicked(self, button):
global app
# style name is lower case version of objectName with rdb removed
style_name = self.bgrpRadio.checkedButton().objectName()
style_name = style_name.replace('rdb', '').lower()
print(style_name)
app.setStyle(QStyleFactory.create(style_name))
@QtCore.pyqtSlot()
def on_btnMessageBox_clicked(self):
buttonReply = QMessageBox.question(
None, 'Exit', "Quit Program?",
QMessageBox.Yes | QMessageBox.No, QMessageBox.No)
if __name__ == '__main__':
app = QApplication([])
win = MainWindow()
win.show()
app.exec_()

在我的例子中,默认情况下,我会在Linux和PyQt5 5.15.0以及python 3中获得下划线,您的环境是什么?环境:PyQt5版本:5.14.1,python 3.8.2,ubuntu 20。04@eyllanesc:感谢您提供指向更新的pyqt5版本的指针。这立刻解决了我的问题。所以这是一个Qt错误
