Python 禁用下一步按钮pyqt5 QQ向导的enterkey

我正在

QWizard

我有

QLineEdit

和

QPushButton

# Enter token
self.enter_token_box = QLineEdit()
# Enter token button
self.btn = QPushButton('OK')
# connect button to function, checks the token..
self.btn.clicked.connect(self._EnterToken)

我在这一行中输入了一个回车键，并运行与单击“OK”按钮相同的功能

问题是它将触发向导的

OK

按钮和

Next

按钮

MVCE:

import sys
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *


class Wizard(QWizard):
    def __init__(self, parent=None):
        super(Wizard, self).__init__(parent)

        self.addPage(EnterToken(self)) 
        self.addPage(ProcessData(self))

class EnterToken(QWizardPage):
    def __init__(self, parent=None):
        super(EnterToken, self).__init__(parent)

        self.setTitle("Enter your token here")
        self.setSubTitle(" ")           

        # Enter Token Widgets
        self.label = QLabel()
        self.enter_token_box = QLineEdit()        

        self.btn = QPushButton('OK')

        # layout options
        layout = QVBoxLayout()
        layout.addWidget(self.label)        
        self.label.setText("Enter Your 12 Digit Code.")
        layout.addWidget(self.enter_token_box)
        layout.addWidget(self.btn)

        # Enter Key TRigger
        self.enter_token_box.returnPressed.connect(self._EnterToken)

        self.btn.clicked.connect(self._EnterToken)

        self.setLayout(layout)        


    def _EnterToken(self):
        """ Method for processing user input after the button is pressed"""

        QMessageBox.about(self, "I want only this!!", "I want only you and not the next page!!")


class ProcessData(QWizardPage):
    """ Sensor Code Entry """
    def __init__(self, parent=None):
        super(ProcessData, self).__init__(parent)        

        # num of logs combo box
        self.num_logs_combo = QComboBox(self)

        # ~buttons
        self.btn = QPushButton('OK')

        layout = QVBoxLayout()
        layout.addWidget(self.num_logs_combo)
        layout.addWidget(self.btn)  
        self.setLayout(layout)    

if __name__ == '__main__':
    app = QApplication(sys.argv)
    wizard = Wizard()
    wizard.show()
    sys.exit(app.exec_())

如果运行上述代码并单击

确定

，您将保留在页面上。如果选择了

QLineEdit

框之外的任何内容，也会发生同样的情况

如果您在

QLineEdit

框中并按

Enter

，您将进入下一页并显示消息框

如何阻止

Enter键链接到
Next
按钮

如何访问和覆盖
QWizard
中的
BACK
、
NEXT
和
FINISH
按钮的属性？
要访问按钮，必须使用
按钮（）
方法并传递
QWizard:：WizardButton
，在您的情况下，必须禁用QPushButton的
默认值

class Wizard(QWizard):
    def __init__(self, parent=None):
        super(Wizard, self).__init__(parent)

        self.addPage(EnterToken(self)) 
        self.addPage(ProcessData(self))

    def showEvent(self, event):
        self.button(QWizard.NextButton).setDefault(False)
        super(Wizard, self).showEvent(event)

更新：

class Wizard(QWizard):
    def __init__(self, parent=None):
        super(Wizard, self).__init__(parent)

        self.addPage(EnterToken(self)) 
        self.addPage(ProcessData(self))

        self.buttons = [self.button(t) for t in (QWizard.NextButton, QWizard.FinishButton)]

        for btn in self.buttons:
            btn.installEventFilter(self)

    def eventFilter(self, obj, event):
        if obj in self.buttons and event.type() == QEvent.Show:
            obj.setDefault(False)
        return super(Wizard, self).eventFilter(obj, event)

你可以提供一个，我不能复制你的问题。公平点！！我已经更新了我的答案！我以前试过
setAutoDefault
和
setDefault
，但它在页面类中<代码>设置默认值

在

向导

类中可以完美工作@johnashu如果你是对的，请同时尝试这两种方法，并在复制时删除不正确的一种方法。效果很好。。如何覆盖finish按钮？我的意思是，我添加了相同的自动和不自动功能，并将NextButton更改为FinishButton，它仍然突出显示finish按钮。非常优雅！。。这是完美的，而且对于肾盂疗法来说更有意义！：）

class Wizard(QWizard):
    def __init__(self, parent=None):
        super(Wizard, self).__init__(parent)

        self.addPage(EnterToken(self)) 
        self.addPage(ProcessData(self))

        self.buttons = [self.button(t) for t in (QWizard.NextButton, QWizard.FinishButton)]

        for btn in self.buttons:
            btn.installEventFilter(self)

    def eventFilter(self, obj, event):
        if obj in self.buttons and event.type() == QEvent.Show:
            obj.setDefault(False)
        return super(Wizard, self).eventFilter(obj, event)
