Functions ¶
func CodeIsModifier ¶
CodeIsModifier returns true if given code is a modifier key
func HasAllModifierBits ¶
HasAllModifiersBits tests whether all of given modifier(s) bits were set
func HasAnyModifierBits ¶
HasAnyModifierBits tests whether any of given modifier(s) bits were set
func ModsFmString ¶
ModsFmString returns the modifiers corresponding to given string and the remainder of the string after modifiers have been stripped
func ModsString ¶
ModsString returns the string representation of the modifiers
func SetModifierBits ¶
SetModifierBits sets the bitflags based on a list of key.Modifiers
Types ¶
type Actions ¶
type Actions int32
Actions is the action taken on the key
func (*Actions) FromString ¶
type Chord ¶
type Chord string
key.Chord represents the key chord associated with a given key function -- it is linked to the KeyChordEdit in the giv ValueView system so you can just type keys to set key chords.
func (Chord) OSShortcut ¶
OSShortcut translates Command into either Control or Meta depending on platform
type ChordEvent ¶
type ChordEvent struct {
Event
}
key.ChordEvent reports events that are generated only on keyboard release, and that include the full chord information about all the modifier keys that were present when a non-modifier key was released -- these are generally appropriate for most uses
func (*ChordEvent) Type ¶
func (ev *ChordEvent) Type() oswin.EventType
type Codes ¶
type Codes uint32
Codes is the identity of a key relative to a notional "standard" keyboard.

Physical key codes.
For standard key codes, its value matches USB HID key codes. TODO: add missing codes.
type Event ¶
type Event struct {
oswin.EventBase
// 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 Codes
// Modifiers is bitflags representing a set of modifier keys: ModShift,
// ModAlt, etc. -- bit positions are key.Modifiers
Modifiers int32
// Action is the key action taken: Press, Release, or None (for key repeats).

}
key.Event is a low-level immediately-generated key event, tracking press and release of keys -- suitable for fine-grained tracking of key events -- see also key.ChordEvent for events that are generated only on key press, and that include the full chord information about all the modifier keys that were present when a non-modifier key was released
func (*Event) Chord ¶
Chord returns a string representation of the keyboard event suitable for keyboard function maps, etc -- printable runes are sent directly, and non-printable ones are converted to their corresponding code names without the "Code" prefix.
func (*Event) HasAllModifier ¶
HasAllModifiers tests whether all of given modifier(s) were set
func (*Event) HasAnyModifier ¶
HasAnyModifier tests whether any of given modifier(s) were set
func (*Event) SetModifiers ¶
SetModifiers sets the bitflags based on a list of key.Modifiers
type Modifiers ¶
type Modifiers int32
Modifiers are used as bitflags representing a set of modifier keys -- see SetModifiers method
