Python PyQt5中彈出子視窗解決子視窗一閃而過的問題
方法一：
from PyQt5.QtWidgets import *
import sys
class Main(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("主視窗")
button = QPushButton("彈出子窗", self)
button.clicked.connect(self.show_child)
def show_child(self):
self.child_window = Child()
self
.child_window.show()
class Child(QWidget):
def __init__(self):
super().__init__()
self.setWindowTitle("我是子視窗啊")
# 執行主視窗
if __name__ == "__main__":
app = QApplication(sys.argv)
window = Main()
window.show()
sys.exit(app.exec_())
方法二：
