打开窗口时编辑文本

Question

我正在与Pyqt5和Python合作。每当我打开一个新窗口并且该窗口都有一个LineDit时，我都必须在LineDit中插入，才能写任何文本。有没有办法在我打开窗口的那一刻，首先不得不在窗口上写上文本？

谢谢！

编辑。这是我一直在使用的代码

from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QLabel, QVBoxLayout, QMainWindow
from PyQt5.QtGui import QImage, QPixmap
from PyQt5.QtCore import QTimer, QThread, pyqtSignal, pyqtSlot
from PyQt5 import QtWidgets, QtCore, QtGui

from PyQt5.uic import loadUi

class VentanaInicio(QMainWindow):
    path = "null"
    def __init__(self):
        super(VentanaInicio,self).__init__()
        loadUi('D:\Matt\Combi\Archivo.ui',self)

        self.pushButton.clicked.connect(self.conectar)

    # Abrir Ventana Video
    def conectar(self):
        self.crear_carpeta()
        iniciar = VentanaVideo()
        iniciar.exec_()
    # Salir
    def conectar1(self):
        self.close()

    def crear_carpeta(self):
        VentanaInicio.path = str(self.lineEdit.text())
        if not self.lineEdit.text():
            VentanaInicio.path = "null"

        try:
            os.mkdir(VentanaInicio.path)
            print("Carpeta Creada")
        except FileExistsError:
            print("Carpeta Existe")

        return VentanaInicio.path

多亏了MusicAmante，问题得到了解决。我添加了SetFocus（）。

    def __init__(self):
        super(VentanaInicio,self).__init__()
        loadUi('D:\Matt\Combi\Archivo.ui',self)
        self.lineEdit.setFocus(True)

        self.pushButton.clicked.connect(self.conectar)
