基本上，当按下切换按钮（连接到重新配置方法）时，我希望重新配置方法中的所有内容都作为单独的线程/进程运行，因此主GUI仍然可访问且不被阻止。以下是我的代码的淡化版本。
import sys, time
from PyQt4 import QtGui, QtCore
from PyQt4.Qt import *
#//Popup Class - Will appear when the Switch Button is pressed
class Popup(QWidget):
def __init__(self):
QWidget.__init__(self)
#//nothing here now, it will have a message telling user to wait while program is run
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
grid = QtGui.QGridLayout()
label_header = QtGui.QLabel("TEST RECONFIGURE")
font = label_header.font()
font.setPointSize(24)
label_header.setFont(font)
#//Creating Static Labels that will be placed in the GUI
label_1 = QtGui.QLabel("Menu 1:")
label_2 = QtGui.QLabel("Menu 2:")
label_spacer = QtGui.QLabel("")
label_cfg = QtGui.QLabel("Current Configuration: '/tmp/directory_here' ")
global comboBox1
comboBox1 = QtGui.QComboBox()
comboBox1.addItem("1")
comboBox1.addItem("2")
global comboBox2
comboBox2 = QtGui.QComboBox()
comboBox2.addItem("3")
comboBox2.addItem("4")
#//Switch Button!!!
global switchButton
switchButton = QPushButton("Switch")
switchButton.clicked.connect(self.reconfigure)
quitButton = QtGui.QPushButton('Quit')
quitButton.clicked.connect(QtCore.QCoreApplication.instance().quit)
#//Configure the grid layout
grid.addWidget(label_spacer, 0,0,9,9)
grid.addWidget(label_header, 0,0,1,6)
grid.addWidget(label_1, 1,0,1,1)
grid.addWidget(comboBox1, 2,0,1,1)
grid.addWidget(label_2, 3,0,1,1)
grid.addWidget(comboBox2, 4,0,1,1)
grid.addWidget(switchButton, 5,0,1,2)
grid.addWidget(label_cfg, 6,0,1,9)
grid.addWidget(quitButton, 9,9,1,1)
self.setLayout(grid)
self.setGeometry(640,300,400,600)
self.show()
#//open up the popup window for switch button, and reconfigure
def reconfigure(self):
print "Opening New Window"
self.w = Popup()
self.w.setGeometry(QRect(self.x()+100,self.y()+100,400,200))
self.w.show()
txt1 = str(comboBox1.currentText())
txt2 = str(comboBox2.currentText())
print " reconfiguring to option %s and option %s" %(txt1, txt2)
#
# This is where most of the work is done, and takes about 1/2 an hour for everything to run
# Want to make this method a separate thread/process so the rest of the main GUI is still accessible
# while the program is running as the whole class will be a separate tab in a larger GUI
#
print "all done!"
#//runner
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
我觉得我必须使用线程和信号来实现这一目标，但我没有太多运气。任何帮助将不胜感激。谢谢！
