.. done little step ahead :
import sys
from PyQt4 import QtCore, QtGui
import time
class MyThread(QtCore.QThread):
def run(self):
n = 0
step = 1
while True:
n += step
print n
class Gui(QtGui.QWidget):
def __init__(self, parent=None):
QtGui.QGroupBox.__init__(self, parent)
self.gcenter = QtGui.QPushButton("X", self)
self.gcenter.setAutoRepeat(True)
guiLayout = QtGui.QGridLayout()
guiLayout.addWidget(self.gcenter,1,0)
self.setLayout(guiLayout)
self.thread = MyThread()
self.connect(self.gcenter, QtCore.SIGNAL("clicked()"),
self.thread.start)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
gui = Gui()
gui.show()
sys.exit(app.exec_())
now i need to stop it when i "release" the button,
tried with :
self.connect(self.gcenter, QtCore.SIGNAL("released()"),
self.thread.quit)
but give :
AttributeError: stop

Hi All,
i'm doing my first experience using pyqt and tring to learn more
about it
unlucky i'm not able to solve some problems by myself :-(
i googled a lot about and i tried to use QTassistant
....
but i'm pretty new to programming and i've some difficoult to learn.
i tried to resume my problem in a sample script, that is :
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.gcenter.setAutoRepeat(True)
self.connect(self.gcenter,
QtCore.SIGNAL("clicked()"),self.count)
guiLayout = QtGui.QGridLayout()
guiLayout.addWidget(self.gcenter,1,0)
self.setLayout(guiLayout)
def count(self):
n = 0
step = 1
while True:
n += step
print n
time.sleep(0.5)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
gui = Gui()
gui.show()
sys.exit(app.exec_())
as you can see the gui do not exit from the "while" statment
and it freeze ...
i know, i need to learn more about QTrhead usage...
an example on how to change the previouse code, will give me a great
help!
thanks for help me !!!
