Hello All
i'm tring to learn how to use Qthreads inside my app, so i wrote this example :
(it print out the text from the lineEdit widget, at any "text-changes")
import sys
from PyQt4 import QtCore, QtGui
import time
class Gui(QtGui.QWidget):
def __init__(self, parent=None):
QtGui.QGroupBox.__init__(self, parent)
self.gcenter = QtGui.QPushButton("X", self)
self.textout = QtGui.QLineEdit("default")
self.textout2 = QtGui.QLineEdit("")
guiLayout = QtGui.QGridLayout()
guiLayout.addWidget(self.gcenter,1,0)
guiLayout.addWidget(self.textout,1,1)
self.setLayout(guiLayout)
self.thread = logJ()
self.thread.start()
self.connect(self.gcenter, QtCore.SIGNAL("clicked()"),
self.thread.toggle)
self.connect(self.textout,
QtCore.SIGNAL("textChanged(QString)"), self.thread.setValue)
class logJ(QtCore.QThread):
def __init__(self, parent = None):
QtCore.QThread.__init__(self, parent)
self.value = 0
self.alive = 1
self.running = 0
def run(self):
while self.alive:
while self.running:
try :
a = self.aggiorna()
#startj(0,0)
print a
time.sleep(1)
except :
print 'exit from Joy mode'
def toggle(self):
if self.running:
self.running = 0
else :
self.running = 1
def stop(self):
self.alive = 0
self.running = 0
self.wait()
def setValue(self, value):
self.value = value
def aggiorna(self):
newvalue = str(self.value)
return newvalue
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
gui = Gui()
gui.show()
sys.exit(app.exec_())
####################
as you can see, it start the thread using the value : 0
"self.value = 0"
what i need instead, is to start the thread using the "text" from
"self.textout.text()"
have you any hints ?
thanks a lot for your preciouse help!
regards,
Massimo.
