无法启动使用Qt4和Python 3.4创建的gui应用程序，并且无法找到QStringList类

我在Qt4中创建了GUI Design，你可以看到Design here。

与pyuic4相比，我将设计转换为GuiVezba2DialogQt4.py。 在这里，您可以看到该类的代码：

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _fromUtf8(s):
        return s

try:
    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
    return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig

比我的主python文件 - Vezba2.py我有这个：

import pypyodbc
import DetaljnaTacka
import Poligon
import Parcela
from GuiVezba2DialogQt4 import *
import sys

class MyForm(QtGui.QDialog):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_Dialog()
        self.ui.setupUi(self)
       QtCore.QObject.connect(self.ui.pushButton_4, QtCore.SIGNAL('clicked()'),self.
dispmessage)

    def dispmessage(self):
        self.ui.label_10.setText("Hello ")

if __name__ == "__main__":
    app = QtGui.QGuiApplication(sys.argv)
    myapp = MyForm()
    myapp.show()
    sys.exit(app.exec_())

当我运行程序时，使用debagger我将断点设为myapp=MyForm()。当该步骤尝试执行时，程序结束。我没有看到创建的GUI，我没有看到任何错误。

我该怎么办？

谢谢。

1 个答案:

答案 0 :(得分：0)

我弄错了。我键入：            #include "opencv2/opencv.hpp"代替app = QtGui.QGuiApplication

我有另一个问题。我做了一个app = QtGui.QApplication，我正在尝试用标题标签和数据创建他。

但是，当我尝试这个时：tableWidget

我有错误。我的列表myapp.ui.tableWidget.setHorizontalHeaderLabels(listaPolja)不是listaPolja。

我在网上看到了一些文章，它说我必须先创建QStringList。

QStringList位于QStringList。但是，当我尝试这个时，我发现错误：QtCore.QStringList。

This is Where I saw, that QtCore has QStringList

我该怎么办？
