fuchsia.ui.input

Protocol for iterating over the initial set of active devices.

This iterator is returned upon registering a listener and is used to bootstrap the client's state with the devices that are already present.

Added: HEAD

GetNext

Returns the next batch of active devices.

Returns an empty vector when all existing devices have been iterated through. The client should then close this channel and rely on the DeviceListener for subsequent events.

KeyboardEvent represents event generated by a user's interaction with a keyboard.

Those events are triggered by distinct pressed state changes of the keys.

The state transitions should be as follows: PRESSED -> (REPEAT ->) RELEASED or PRESSED -> (REPEAT ->) CANCELLED

The input system will repeat those events automatically when a code_point is available.

DEPRECATED: Will be removed in favor of fuchsia.ui.input.KeyEvent.

TextRange

Defined in fuchsia.ui.input/text_editing.fidl

A range of characters in a string of text. Although strings in FIDL's wire format are UTF-8 encoded, these indices are measured in UTF-16 code units for legacy reasons. These text input APIs will eventually be replaced by fuchsia.ui.text, which uses code points instead.

Field Type Description Default

TextSelection

Defined in fuchsia.ui.input/text_editing.fidl

A range of text that represents a selection. Although strings in FIDL's wire format are UTF-8 encoded, these indices are measured in UTF-16 code units for legacy reasons. These text input APIs will eventually be replaced by fuchsia.ui.text, which uses code points instead.

Text selection is always directional. Direction should be determined by comparing base and extent.

KeyboardType flexible

Type: uint32

Requests a specific keyboard type from the text editing subsystem.

This is most relevant for virtual keyboards which have some leeway in how the keyboard is presented to the user, as well as which input is acceptable.

For example, a NUMBER keyboard type may only allow decimal numbers to be entered. In addition, a virtual keyboard might only show a numeric keypad for text entry.

Name	Value	Description
TEXT	`0`	Single-line text fields only. Use MULTILINE below for multiline text.
NUMBER	`1`	A text field intended for entering numbers only.
PHONE	`2`	A text field for entering phone numbers only (e.g. digits, limited punctuation, perhaps some validation).

UP	`4`	The pointer has stopped making contact with the device. For `MOUSE` devices, this is triggered when the primary button is released.

TextAffinity strict

Type: uint32

Defined in fuchsia.ui.input/text_editing.fidl

Whether a TextPosition is visually upstream or downstream of its offset.

For example, when a text position exists at a line break, a single offset has two visual positions, one prior to the line break (at the end of the first line) and one after the line break (at the start of the second line). A text affinity disambiguates between those cases. (Something similar happens with between runs of bidirectional text.)

We do not expect new values to be added to this enum.

Name Value Description

Name	Value	Description
UPSTREAM	`0`	The position has affinity for the upstream side of the text position. For example, if the offset of the text position is a line break, the position represents the end of the first line.
DOWNSTREAM	`1`	The position has affinity for the downstream side of the text position. For example, if the offset of the text position is a line break, the position represents the start of the second line.

UPSTREAM

0

The position has affinity for the upstream side of the text position.

For example, if the offset of the text position is a line break, the position represents the end of the first line.

DOWNSTREAM

1

The position has affinity for the downstream side of the text position.

For example, if the offset of the text position is a line break, the position represents the start of the second line.
