QCoreApplication QMetaCallEvent Compression Every queued slot call ends up in the posting of a QMetaCallEvent to the target object. The event contains the sender object, the signal id, the slot index, and packaged call parameters. On Qt 5, the signal id generally doesn’t equal the value returned by QMetaObject::signalIndex(): it is an index computed as … Read more
Use QSocketNotifier to be notified of things being available on stdin. Call nonblocking getch() in a loop until no more input is available. This is vitally important: the notifier will notify only when new data is available, but this doesn’t mean that it notifies on every character! If you receive multiple characters at a time, … Read more
Well, the Qt FAQ says: int main(int argc, char **argv) { QApplication app(argc, argv); QString str1 = “Test”; QByteArray ba = str1.toLocal8Bit(); const char *c_str2 = ba.data(); printf(“str2: %s”, c_str2); return app.exec(); } So perhaps you’re having other problems. How exactly doesn’t this work?
Put the loop variable in a default argument, like this: lambda state, instance=instance: findInstance.projectsInstance.myslot( “TWCH”, findInstance, instance.text(), instance.checkState(), instance) This will give each lambda its own local copy of the instance variable. EDIT Here’s a simple script that demonstrates how to use default lambda arguments: from PyQt4 import QtGui class Window(QtGui.QWidget): def __init__(self): QtGui.QWidget.__init__(self) layout … Read more
