pyqt 向导在向导结束时添加页面(setFinishButtonEarly)

pyqt wizard add page on end of wizard (setFinishButtonEarly)

我正在寻找资源以查看 pyqt4 中的某些方法。

我有一个 finalPage,它从 class 向导获取参数,并希望根据该参数显示一些结果,完成按钮应该在 [=22] 的最后一个=] 向导和 finalPage 只有关闭按钮。

我的代码

from PyQt4 import QtCore, QtGui
import sys
from ex import dbconnect
data = [['Male', 0, 'cheap', 'Low', 'Bus'], ['Male', 1, 'cheap', 'Medium', 'Bus'], ['Female', 1, 'cheap', 'Medium', 'Train'], ['Female', 0, 'cheap', 'Low', 'Bus'], ['Male', 1, 'cheap', 'Medium', 'Bus'], ['Male', 0, 'standard', 'Medium', 'Train'], ['Female', 1, 'standard', 'Medium', 'Train'], ['Female', 1, 'expensive', 'High', 'Car'], ['Male', 2, 'expensive', 'Medium', 'Car'], ['Female', 2, 'expensive', 'High', 'Car']]
data1 = ['Gender', 'car ownership', 'Travel Cost', 'Income Level', 'Transportation mode']

#this class i got helped with it

class Wizard(QtGui.QWizard):

   def __init__(self):

               if not x in y:
                   y.append(x)
           datas.append(y)
       titles = data1
       self.setStyleSheet(('font:50 10pt "MS Shell Dlg 2";'))

   global data, data1
   app = QtGui.QApplication(sys.argv)

       app = QtGui.QApplication([])

   wizard.addpage(finalpage(wizard.results())

run1()

不知道何时何地调用最终页面

如果要在更改页面之前从 QWizard 或 QWizardPage 获取信息,则必须重写 initializePage 方法。
