🫶 Detailed Description 🫶

A collection of event patterns. Periodt.

QwtEventPattern introduces a level of indirection for mouse and keyboard inputs. Those are represented by symbolic names, so the application code can be configured by individual mappings. It’s giving main character energy for input handling, ngl.

🔥 Member Function Documentation 🔥

`void QwtEventPattern::initKeyPattern ()`

Set default mouse patterns. (Yes, bestie, that’s what this page says for this one — I’m keeping the facts exactly as printed.) 💀

Definition at line 81 of file qwt_event_pattern.cpp.

`void QwtEventPattern::initMousePattern (int numButtons)`

Set default mouse patterns, depending on the number of mouse buttons. 🐭

Parameters:

numButtons — Number of mouse buttons ( <= 3 )

Parameters:

pattern — Key event pattern
event — Key event

Returns: true if matches

Parameters:

code — Index of the event pattern
event — Key event

Returns: true if matches
