[SOLVED] Connecting signal and slot between ... - Qt Forum Hello, I have an application with a main widget (parentWidget). Within my main widget I create a new widget (we can call it childWidget). Within childWidget I create a new widget (call it grandchildWidget). I want to connect a signal from my grandchild to... How to Use Signals and Slots - Qt Wiki A developer can choose to connect to a signal by creating a function (a slot) and calling the connect() function to relate the signal to the slot. Qt's signals and slots mechanism does not require classes to have knowledge of each other, which makes it much easier to develop highly reusable classes. Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. Connect QML Signal with C++ Slot | Qt Forum

Not only you can now use typedef or namespaces properly, but you can also connect signals to slots that take arguments of different types if an implicit conversion is possible. In the following example, we connect a signal that has a QString as a parameter to a slot that takes a QVariant.
Qt 4.1: Qt Designer's Signals and Slots Editing Mode Both widgets and layout objects can be connected via an intuitive connection interface, and Qt Designer will present a menu of compatible signals and slots to use for each connection made.

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. It is necessary to inform the object, its signal (via macro ...
