Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Enter

enter event

Notify the text_input object when it received focus. Typically in response to an activate request.

Fields of Enter

surface: WlSurface
Leave

leave event

Notify the text_input object when it lost focus. Either in response to a deactivate request or when the assigned surface lost focus or was destroyed.

ModifiersMap

modifiers map

Transfer an array of 0-terminated modifier names. The position in the array is the index of the modifier as used in the modifiers bitmask in the keysym event.

Fields of ModifiersMap

map: Vec<u8>
InputPanelState

state of the input panel

Notify when the visibility state of the input panel changed.

Fields of InputPanelState

state: u32
PreeditString

pre-edit

Notify when a new composing text (pre-edit) should be set around the current cursor position. Any previously set composing text should be removed.

The commit text can be used to replace the preedit text on reset (for example on unfocus).

The text input should also handle all preedit_style and preedit_cursor events occurring directly before preedit_string.

Fields of PreeditString

serial: u32text: Stringcommit: String
PreeditStyling

pre-edit styling

Sets styling information on composing text. The style is applied for length bytes from index relative to the beginning of the composing text (as byte offset). Multiple styles can be applied to a composing text by sending multiple preedit_styling events.

This event is handled as part of a following preedit_string event.

Fields of PreeditStyling

index: u32length: u32style: u32
PreeditCursor

pre-edit cursor

Sets the cursor position inside the composing text (as byte offset) relative to the start of the composing text. When index is a negative number no cursor is shown.

This event is handled as part of a following preedit_string event.

Fields of PreeditCursor

index: i32
CommitString

commit

Notify when text should be inserted into the editor widget. The text to commit could be either just a single character after a key press or the result of some composing (pre-edit). It could also be an empty text when some text should be removed (see delete_surrounding_text) or when the input cursor should be moved (see cursor_position).

Any previously set composing text should be removed.

Fields of CommitString

serial: u32text: String
CursorPosition

set cursor to new position

Notify when the cursor or anchor position should be modified.

This event should be handled as part of a following commit_string event.

Fields of CursorPosition

index: i32anchor: i32
DeleteSurroundingText

delete surrounding text

Notify when the text around the current cursor position should be deleted.

Index is relative to the current cursor (in bytes). Length is the length of deleted text (in bytes).

This event should be handled as part of a following commit_string event.

Fields of DeleteSurroundingText

index: i32length: u32
Keysym

keysym

Notify when a key event was sent. Key events should not be used for normal text input operations, which should be done with commit_string, delete_surrounding_text, etc. The key event follows the wl_keyboard key event convention. Sym is an XKB keysym, state a wl_keyboard key_state. Modifiers are a mask for effective modifiers (where the modifier indices are set by the modifiers_map event)

Fields of Keysym

serial: u32time: u32sym: u32state: u32modifiers: u32
Language

language

Sets the language of the input text. The "language" argument is an RFC-3066 format language tag.

Fields of Language

serial: u32language: String
TextDirection

text direction

Sets the text direction of input text.

It is mainly needed for showing an input cursor on the correct side of the editor when there is no input done yet and making sure neutral direction text is laid out properly.

Fields of TextDirection

serial: u32direction: u32
