使用 qt designer 在 pyqt 中打印来自文本框和 LineEdit 的值

Question

这是我的 test_gui.py 文件。这是从 QT 设计器生成的 .ui 文件中隐藏的。

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。在这里：我正在尝试将文本框和 lineedit 中的文本打印到输出。在 textBox 中，我们有用户输入的详细信息，lineedit 将包含文件名。我需要做的就是在屏幕上打印用户详细信息和文件名。我收到以下错误：

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_())

Answer 1

我想你在方法 generate_report.

的以下几行中忘记了 .ui

此外，你不能打电话给textEdit.text()，恐怕。

这里有一个替换建议：

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