Managing Events, Custom Signals, and Slots

This chapter introduces the concept of events. To maintain a working state, messages are passed around from the windowing system to the application, and within the application itself. These messages may contain data that could be useful when delivered at some destination. The messages being talked about here are referred to as events in Qt.

In this chapter, we will cover the following topics:

• Events
• Event handlers
• Drag and drop
• Custom signals
