But you try to connect to, so indeed there is no such slot! @SLOT (proccessData (reply,object))@. You need to change that to: @SLOT (proccessData (QNetworkReply*, QScrollArea*))@. Also you may consider changing your function's signature to: @proccessData (const QNetworkReply &reply const QScrollArea &area)@. Reply Quote. 0.

[solved] "No such slot" error | Qt Forum.

The Qt signals/slots and property system are based on the ability to introspect the objects at runtime. Introspection means being able to list the methods and properties of an object and have all kinds of information about them such as the type of their arguments. QtScript and QML would have hardly. Invokes the member (a signal or a slot name) on the object obj. Returns true if the member could be invoked. Returns false if there is no such member or the parameters did not match. The invocation can be either synchronous or asynchronous, depending on type: If type is Qt::DirectConnection, the member will be invoked immediately..

5. I think the problem is that in your SLOT definition you put a variable name "depart" in, which is not correct. The SLOT and SIGNAL definitions must only have the function name and types. So: connect (chp3, SIGNAL (clicked ()), this, SLOT (prendpixel1 (Pixel))); BTW I think it is also space sensitive, so SLOT (anotherfn (Pixel, Pixel)) would. Signals and slots were one of the distinguishing features that made Qt an exciting and innovative tool back in time. So since Qt 5.0, a new overload to QObject::connect exists, and supports passing as second and fourth arguments a function pointer to specify which member function should be called.

This section provides an overview of what Qt is, and why a developer might want to use it. It should also mention any large subjects within Qt, and link out to the related topics.

Problem is that I keep getting the 'No Such Slot' runtime error in Qt Creator every time I launch a 'settings' window from my main window. I've found Qt to be quite counter-intuitive so far and this slots 'n signals concept seems a bit of a stretch from simply passing vars or function calls.

Qt4 - Error 'no such slot' qt - Stack Overflow.

Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that Slots can be used for receiving signals, but they are also normal member functions. Just as an object does not know if anything receives its signals, a slot.

Re: No Such Slot. the signal from your sizeslider has the name "valueChanged (int)". Using the connection by name. Qt tries to connect the slot on_sizeslider_valuechanged (int) to a signal valuechanged (int) of sizeslider. The slider signal is valueChanged (int) (capital C), so no connection can be established.

General and Desktop. QObject::connect: No such slot error. MainWindow* mainWin = new MainWindow; mainWin->show(); } Also, for destroying the objects when closed, I use, setAttribute(Qt::WA_DeleteOnClose); in the Mainwindow's constructor. While developing with Qt Signal/Slots, I came across a few segmentation faults that had me puzzled as to what was causing it. I found, most unfortunately, when trying to change such error checks into obnoxiously-loud assertions that there were thousands of places in the system that were violating.
