Qt signal slot custom class

By Guest

I'm using Qt Creator 2.0.1 and I have a custom slot my QMainWindow ... now I have a pushbutton, which on clicked should call the custom slot on the main window. Can do in code yes, but can't do this with the signal-slot editor. When I open the signal-slot editor, I see the custom slot on the right but the entire set of slots are disabled.

Creating Custom Qt Types | Qt 4.8 Standard types such as QSize, QColor and QString can all be stored in QVariant objects, used as the types of properties in QObject-based classes, and emitted in signal-slot communication. In this document, we take a custom type and describe how to integrate it into Qt's object model so that it can be stored in the same way as standard Qt types.

Contents: Overview. In the Custom Type Example, we showed how to integrate custom types with the meta-object system, enabling them to be stored in QVariant objects, written out in debugging information and used in signal-slot communication.. In this example, we create a new value class, Block, and register it with the meta-object system to enable us to send instances of it between threads ... Signals & Slots — Qt for Python 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.
