Ui_MainWindow 是由 designer 和 pyuic 生成的 .py 文件，我想将 PyQt GUI 元素文本值传递给另一个文件并进行一些基本操作并返回结果。
父文件

子文件 我试图从子文件中获取输入文本值...
from PyQt4 import QtCore, QtGui
from blog_tool import Ui_MainWindow
class Valued(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
app = self.ui.setupUi(self)
def callingdata():
blog_title = app.lineEdit.text()
blog_body = app.textEdit.toPlainText()
blog_tag = app.lineEdit_2.text()
print "Title\n\t%s\nBody\n\t%s\nTag\n\t%s" % (blog_title, blog_body, blog_tag)
请您参考如下方法:
您的示例代码有一些问题。主要问题是您正在修改 pyuic 生成的 GUI 模块，您永远不应该这样做。始终将 GUI 模块导入到您的主应用程序中，并在其中添加所有额外代码。
其他问题主要是由于未正确引用 GUI 中的小部件引起的。在您的示例中，这些都将成为您创建的 Ui_MainWindow 对象的属性，因此您可以通过 self.ui 访问它们。
我已经在下面重写了您的非 GUI 模块，以向您展示事情应该如何一起进行。但在尝试之前，请确保重新生成 GUI 模块。
from PyQt4 import QtCore, QtGui
from blog_tool import Ui_MainWindow
class Valued(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.ui.pushButton.clicked.connect(self.callingdata)
def callingdata(self):
blog_title = self.ui.lineEdit.text()
blog_body = self.ui.textEdit.toPlainText()
blog_tag = self.ui.lineEdit_2.text()
print "Title\n\t%s\nBody\n\t%s\nTag\n\t%s" % (
blog_title, blog_body, blog_tag)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Valued()
window.show()
sys.exit(app.exec_())
