event

Overview ¶

Package event contains the types for event handling.

The Queue interface is the protocol for receiving external events.

For example:

var queue event.Queue = ...

for _, e := range queue.Events(h) {
	switch e.(type) {
		...
	}
}

In general, handlers must be declared before events become available. Other packages such as pointer and key provide the means for declaring handlers for specific event types.

The following example declares a handler ready for key input:

import github.com/cybriq/p9/pkg/gel/gio/io/key

ops := new(op.Ops)
var h *Handler = ...
key.InputOp{Tag: h}.Add(ops)
