这无疑是一个简单的问题，但我似乎无法得到它。我想要做的就是点击按钮运行一个功能。我创建了一个.ui并将其转换为.py文件并将其导入为Ui_Dialog。 gui本身打开正常，我的pushButton称为btn_browseDEM，lineEdit称为lineEdit_DEM。帮助??
class MyDialog(QDialog):
def __init__(self):
QDialog.__init__(self)
# Set up the user interface from Designer.
self.ui = Ui_Dialog()
self.ui.setupUi(self)
self.ui.btn_browseDEM.clicked.connect(self.btn_browseDEM_clicked)
def btn_browseDEM_clicked(self):
self.ui.lineEdit_DEM.setText('hello')
app = QApplication(sys.argv)
window = QDialog()
gui = MyDialog()
gui.ui.setupUi(window)
window.show()
sys.exit(app.exec_())
转换后的ui文件

您可能想直接显示创建的gui。
app = QApplication(sys.argv)
gui = MyDialog()
gui.show()
sys.exit(app.exec_())
