Overview ¶
Package key defines an event for physical keyboard keys.
On-screen software keyboards do not send key events.
See the golang.org/x/mobile/app package for details on the event model.

Physical key codes.
For standard key codes, its value matches USB HID key codes. TODO: add missing codes.
type Event ¶
type Event struct { // Rune is the meaning of the key event as determined by the // operating system. The mapping is determined by system-dependent // current layout, modifiers, lock-states, etc. // // If non-negative, it is a Unicode codepoint: pressing the 'a' key // generates different Runes 'a' or 'A' (but the same Code) depending on // the state of the shift key. // // If -1, the key does not generate a Unicode codepoint. To distinguish // them, look at Code. Rune rune // Code is the identity of the physical key relative to a notional // "standard" keyboard, independent of current layout, modifiers, // lock-states, etc // // For standard key codes, its value matches USB HID key codes. // Compare its value to uint32-typed constants in this package, such // as CodeLeftShift and CodeEscape. // // Pressing the regular '2' key and number-pad '2' key (with Num-Lock) // generate different Codes (but the same Rune). Code Code // Modifiers is a bitmask representing a set of modifier keys: ModShift, // ModAlt, etc. Modifiers Modifiers // Direction is the direction of the key event: DirPress, DirRelease, // or DirNone (for key repeats). Direction Direction }
