有人能告诉我应该如何喜欢我的代码,或者我做错了什么吗? 我想使用“btn\u run”按钮来运行“view\u splash”功能。但有些人认为这是错误的,但“查看”不会启动。它没有显示错误。你知道吗
import sys
from PyQt4 import QtGui, QtCore
import time
class Window(QtGui.QMainWindow):
def __init__(self):
super(Window, self).__init__()
self.setGeometry(500, 150, 500, 600)
self.setWindowTitle('Test GUI')
self.threadclass = AThread()
self.connect(self.threadclass, QtCore.SIGNAL("view_splash()"), self.view_splash)
self.home()
def home(self):
btn_run = QtGui.QPushButton("Run", self)
self.threadclass = AThread()
btn_run.clicked.connect(self.threadclass.start)
btn_run.resize(120, 40)
btn_run.move(190, 540)
self.show()
def view_splash(self):
print('test')
label = QLabel("<font color=red size=10<b>" + "SPLASH" + "</b></font>")
label.setWindowFlags(Qt.SplashScreen | Qt.WindowStaysOnTopHint)
label.show()
QtCore.QTimer.singleShot(5000, label.close)
class AThread(QtCore.QThread):
def __init__(self):
super(AThread, self).__init__()
def run(self):
print(1)
print(2)
time.sleep(5)
print(3)
print(4)
self.emit(QtCore.SIGNAL("view_splash()"))
app = QtGui.QApplication(sys.argv)
GUI = Window()
sys.exit(app.exec_())
你需要创建和连接不同的信号。你知道吗
