Qt signalplats segmenteringsfel

So from Qt 4.6, a new internal signal index which only includes the signal index is used. While developing with Qt, you only need to know about the absolute method index. But while browsing the Qt's QObject source code, you must be aware of the difference between those three. How Connecting Works.

I found out today that Qt’s slots/signals architecture is even better than I thought. Normally, developers connect widget signals to widget slots to be notified of events. Today I discovered that signals can actually be connected to other signals, which saved me from writing some really stupid code… This may seem weird, but consider this

Member Function Documentation QSignalBlocker:: QSignalBlocker (QSignalBlocker &&other) Move-constructs a signal blocker from other.other will have a no-op destructor, while responsibility for restoring the QObject::signalsBlocked() state is transferred to the new object. A list of texts is passed to the constructor. A signal mapper is constructed and for each text in the list a QPushButton is created. We connect each button's clicked() signal to the signal mapper's map() slot, and create a mapping in the signal mapper from each button to the button's text. My app, consists in 2 different object (QObject and QMainWIndow), and I am wondering how to communicate between them with SLOT/SIGNAL. Moreover, does existing better approach ? The remaining functions are qRound() and qRound64(), which both accept a double or float value as their argument returning the value rounded up to the nearest integer and 64-bit integer respectively, the qInstallMessageHandler() function which installs the given QtMessageHandler, and the qVersion() function which returns the version number of Qt at run-time as a string. Sep 16, 2005 · I found out today that Qt’s slots/signals architecture is even better than I thought. Normally, developers connect widget signals to widget slots to be notified of events. Today I discovered that signals can actually be connected to other signals, which saved me from writing some really stupid code… This may seem weird, but consider this HI, I wish to make a connection, and I'm aware that they both must have the same type of parameter in order to work. My question is: Is there a way, or workaround, to this issue? In my project, I want to connect a simple valuechanged signal to a a slot th A signal event is generated by a QStateMachine in response to a Qt signal. The QSignalTransition class provides a transition associated with a signal event. QStateMachine::SignalEvent is part of The State Machine Framework .

QtCore.SIGNAL() and QtCore.SLOT() macros allow Python to interface with Qt signal and slot delivery mechanisms. This is the old way of using signals and slots. The example below uses the well known clicked signal from a QPushButton. The connect method has a non python-friendly syntax.

A list of texts is passed to the constructor. A signal mapper is constructed and for each text in the list a QPushButton is created. We connect each button's clicked() signal to the signal mapper's map() slot, and create a mapping in the signal mapper from each button to the button's text. Finally we connect the signal mapper's mappedString() signal to the custom widget's clicked() signal.
