In today's fast-paced business environment, where responsiveness and user experience are paramount, Qt signals and slots have emerged as a game-changer in software development. This powerful communication mechanism enables seamless interaction between different components of an application, ensuring lightning-fast response times and a seamless user experience.
Qt signals are events emitted by objects to notify other parts of the application about a specific occurrence, such as a button click or a change in a data structure. Qt slots are member functions of objects that are invoked when a specific signal is received. This decoupled communication mechanism provides a highly flexible and efficient way to structure your code and handle events in a concise and maintainable way.
Signal | Description |
---|---|
clicked() | Emitted when a button is clicked |
valueChanged(int) | Emitted when the value of an integer property changes |
textChanged(QString) | Emitted when the text of a string property changes |
Slot | Description |
---|---|
onButtonClicked() | Invoked when the clicked() signal is emitted |
onValueChanged(int) | Invoked when the valueChanged(int) signal is emitted |
onTextChanged(QString) | Invoked when the textChanged(QString) signal is emitted |
