[PyQt] QxtSignalWaiter port

[Jason Hihn]

I was trying to get QxtSignalWaiter
(http://qtnode.net/wiki?title=QxtSignalWaiter) ported so I can use QHttp
with a synchronous process. 

 

The problem I am having is wait2()'s while never ends before the timeout,
meaning self.ready is always false, so it waits for the entire duration. 

 

My invocation:

self.w=SignalWaiter.QxtSignalWaiter(self.http, 'done(bool)')

self.http.get(getdata)

self.w.wait2(5000)

 

My implementation follows:

from PyQt4.Qt import * 

 

class QxtSignalWaiter(QObject):

            def __init__(self, sender, signal):

                        apply(QObject.__init__, (self, ) + ())

                        self.connect(sender, SIGNAL(signal), self,
SLOT('signalCaught'))

 

            def wait1(self, sender, signal, msec):

                        '''Returns True if the signal was caught, returns
False if the wait timed out'''

                        w=QxtSignalWaiter(sender, signal)

                        return w.wait2(msec)

 

            def wait2(self, msec):

                        ''' Returns True if the signal was caught, returns
False if the wait timed out'''

                        if(msec < -1): 

                                    return False

                        

                        if(msec != -1): 

                                    self.timerID = self.startTimer(msec)

                        

                        self.ready = self.timeout = False

                        while(self.ready==False and self.timeout==False):

 
QCoreApplication.processEvents(QEventLoop.WaitForMoreEvents)

                        

                        self.killTimer(self.timerID)

                        return self.ready or self.timeout

                        

            def signalCaught(self):

                        print 'signalCaught'

                        self.ready = True

 

            def timerEvent(self, event):

                        self.killTimer(self.timerID)

                        self.timeout = True
