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.

No Such Slot Qt When you trying to link the slots and signals together you need to have a QObject::connect and also a emitting, I have created a basic demonstration of this with a QPushButton (link to qt signal and slots, and a QT link for the signal and slots). Qt connect "no such slot" when slot definitely does exist. I have a QMainWindow based class and I'm trying to send it signals involving QUuid. Object::connect: No such slot MainWindow::on_comp_connected (QUuid) in..\..\src\ Object::connect: (receiver name: 'MainWindow') It's driving me potty as the slot definitely does exist.

Function such as QHostInfo::lookupHost (until Qt 5.9) or QTimer::singleShot (until Qt 5.4) or QFileDialog::open take a QObject receiver and char* slot. This does not work for the new method. If one wants to do callback C++ way, one should use std::function But we cannot use STL types in our ABI, so a QFunction should be done to copy std::function.

SLOT. If you have a python slot, you can specify it just by tipping the method: previousRange.setValue. This works for all methods accessible by Python. If your slots should be accessible like C++ Qt slots, as you tried in your code, you have to use a special syntax. You can find information about pyqtSignature decorator on the PyQt website.

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. See also Supported HTML Subset and plainText.. lineWrapColumnOrWidth: int. This property holds the position (in pixels or columns depending on the wrap mode) where text will be wrapped. If the wrap mode is FixedPixelWidth, the value is the number of pixels from the left edge of the text edit at which text should be wrapped.If the wrap mode is FixedColumnWidth, the value is the column number. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop. Example.

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.
