UI events with signals and slots
In the previous recipe, we demonstrated the use of signals and slots on a push button. Now, let’s explore the signals and slots that are available in other common widget types.
How to do it…
To learn how to use signals and slots with UI events, follow these steps:
- Let’s create a new Qt Widgets Application project.
- Drag and drop a PushButton, Combo Box, Line Edit, Spin Box, and Slider widget from the Widget Box into your UI canvas:
