各位達人，遇到一個奇怪的問題：python3.7+pyqt5，滑鼠劃過選單欄時狀態欄內容就會消失
見下圖：
代碼如下：
Qt Designer自動生成的代碼：
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):

自己寫的視窗類：
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QFileDialog
import MainWindowTemplate
class MyWindow(QtWidgets.QMainWindow, MainWindowTemplate.Ui_MainWindow):
def __init__(self, parent=None):
super(MyWindow, self).__init__(parent)
self.setupUi(self)
self.init_ui()
self.pb_open.clicked.connect(self.open_file)
self.action_open.triggered.connect(self.open_file)
def init_ui(self):
self.setWindowTitle('PyQt MainWindow 模板')
self.resize(600, 400)
self.move_center()
self.status = self.statusBar()
self.status.showMessage('這是狀態欄。')
def move_center(self):
size_screen = QtWidgets.QDesktopWidget().screenGeometry()
size_window = self.geometry()
x = int((size_screen.width()-size_window.width())/2)
y = int((size_screen.height()-size_window.height())/2)
self.move(x, y)
def open_file(self):
file, ok = QFileDialog.getOpenFileName(self, '打開檔案', 'J:\\', '所有檔案(*.*);;文本檔案(*.txt)')
if ok:
self.status.showMessage(file)
主函式：
import sys
from PyQt5 import QtWidgets
import MyWindow
import ctypes
def hide_window():
wnd_cmd = ctypes.windll.kernel32.GetConsoleWindow()
if wnd_cmd != 0:
ctypes.windll.user32.ShowWindow(wnd_cmd, 0)
ctypes.windll.kernel32.CloseHandle(wnd_cmd)
def main():
app = QtWidgets.QApplication(sys.argv)
window = MyWindow.MyWindow()
window.show()
sys.exit(app.exec_())
if __name__ == '__main__':
hide_window()
main()
uj5u.com熱心網友回復：
showMessage() 有一個 timeout 引數，標識超時時間，當超過這個時長時，文本就會消失。如果不設定 timeout，則會一直顯示，除非主動呼叫 clearMessage()。
uj5u.com熱心網友回復：
timeout引數未設，文本消失是因為滑鼠劃過了選單欄，只要滑鼠不劃過選單欄，等多久文本都不會消失。

你好，我也遇到了同樣的問題，請問解決了嗎，我試了下使用QTimer方法可以讓訊息一直顯示轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/226692.html
