这是我的test_gui.py文件。这是从QT设计器生成的.ui文件转换而来的。

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    test_gui = QtGui.QDialog()
    ui = Ui_test_gui()
    ui.setupUi(test_gui)
    test_gui.show()
    sys.exit(app.exec_())

我正在使用另一个代码来调用此代码并使用自定义插槽实现它。这里是：我正在尝试打印文本框中的文本并将lineedit输出到输出。在textBox中，我们有用户输入的详细信息，lineedit将包含文件名。我只需要在屏幕上打印用户详细信息和文件名。我得到以下错误：

Traceback (most recent call last): File "C:\cygwin64\home\Actual_test_gui.py", line 29, in generate_report data_line = self.lineEdit.displayText() AttributeError: 'AppGui' object has no attribute 'lineEdit'

import sys, os, shutil, glob
from PyQt4 import QtCore, QtGui 
from test_gui import Ui_test_gui
from __builtin__ import str, int
from subprocess import Popen

class AppGui(QtGui.QDialog,Ui_test_gui):
    def __init__(self):
        QtGui.QDialog.__init__(self)
        self.ui = Ui_test_gui()
        self.ui.setupUi(self)
        self.ui.pushButton.clicked.connect(self.generate_report)

    def generate_report(self):
        data_text = self.textEdit.text().ascii()
        data_line = self.lineEdit.displayText()
        print data_line
        print data_text

app = QtGui.QApplication(sys.argv)
window = AppGui()
ui = Ui_test_gui()
window.show()
sys.exit(app.exec_())

我想您忘记了.ui方法generate_report中的下面几行。

另外，恐怕你不能打电话给textEdit.text()。

这里有一个替代方案：

data_text = self.ui.textEdit.toPlainText()
data_line = self.ui.lineEdit.displayText()
