Detailed Description

TextInput represents a Wayland interface for text input.

The TextInput allows to have text composed by the Compositor and be sent to the client.

Depending on the interface the TextInputManager got created for this class encapsulates one of the following interfaces:

• wl_text_input
• zwp_text_input_v2

Member Enumeration Documentation

enum KWayland::Client::TextInput::ContentHint : uint32_t

Enumerator
None	no special behaviour
AutoCompletion	suggest word completions
AutoCorrection	suggest word corrections
AutoCapitalization	switch to uppercase letters at the start of a sentence
LowerCase	prefer lowercase letters
UpperCase	prefer uppercase letters

Time	input a time
DateTime	input a date and time
Terminal	input for a terminal

Definition at line 177 of file textinput.h.

enum KWayland::Client::TextInput::KeyState

strong

The possible states for a keyEvent.

Definition at line 120 of file textinput.cpp.

QByteArray KWayland::Client::TextInput::composingText

(

)

const

The currently being composed text around the composingTextCursorPosition.

Definition at line 115 of file textinput.cpp.

void KWayland::Client::TextInput::composingTextChanged ( )

signal

Emitted whenever the composing text and related states changed.

See also

composingText

composingTextCursorPosition

composingFallbackText

qint32 KWayland::Client::TextInput::composingTextCursorPosition

const

The cursor position inside the composingText (as byte offset) relative to the start of the composingText.

If index is a negative number no cursor is shown.

See also

composingText

composingTextChanged

Definition at line 110 of file textinput.cpp.

qint32 KWayland::Client::TextInput::cursorPosition

(

)

const

The cursor position in bytes at which the commitText should be inserted.

See also

committed

Definition at line 130 of file textinput.cpp.

TextInput::DeleteSurroundingText KWayland::Client::TextInput::deleteSurroundingText

(

)

const

Returns

The length in bytes which should be deleted around the cursor position

See also

committed

Definition at line 135 of file textinput.cpp.

void KWayland::Client::TextInput::disable

(

Surface *

surface

)

Disable text input in a surface (typically when there is no focus on any text entry inside the surface).

See also

enable

Definition at line 60 of file textinput.cpp.

void KWayland::Client::TextInput::enable

(

Surface *

surface

)

Enable text input in a surface (usually when a text entry inside of it has focus).

This can be called before or after a surface gets text (or keyboard) focus via the enter event. Text input to a surface is only active when it has the current text (or keyboard) focus and is enabled.

See also

deactivate

Definition at line 55 of file textinput.cpp.

void KWayland::Client::TextInput::entered ( )

signal

Emitted whenever a Surface is focused on this TextInput.

See also

enteredSurface

left

Surface * KWayland::Client::TextInput::enteredSurface

(

)

const

Returns

The Surface which has the text input focus on this TextInput.

See also

entered

left

Definition at line 45 of file textinput.cpp.

void KWayland::Client::TextInput::hideInputPanel

(

)

Requests input panels (virtual keyboard) to hide.

state	Whether the event represents a press or release event
modifiers	The hold modifiers on this event
time	Timestamp of this event

QByteArray KWayland::Client::TextInput::language

language

void KWayland::Client::TextInput::left ( )

signal

Emitted whenever a Surface loses the focus on this TextInput.

Should be called by an editor widget when the input state should be reset, for example after the text was changed outside of the normal input method flow.

Definition at line 75 of file textinput.cpp.

void KWayland::Client::TextInput::setContentType	(	ContentHints	hints,
		ContentPurpose	purpose
	)

Sets the content purpose and content hints.

Definition at line 85 of file textinput.cpp.

void KWayland::Client::TextInput::setCursorRectangle

(

const QRect &

rect

)

Sets the cursor outline rect in surface local coordinates.

Allows the compositor to e.g. put a window with word suggestions near the cursor.

Definition at line 90 of file textinput.cpp.

void KWayland::Client::TextInput::setPreferredLanguage

(

const QString &

language

)

Sets a specific language.

This allows for example a virtual keyboard to show a language specific layout. The language argument is a RFC-3066 format language tag.

Definition at line 95 of file textinput.cpp.

void KWayland::Client::TextInput::setSurroundingText	(	const QString &	text,
		quint32	cursor,
		quint32	anchor

Sets the plain surrounding text around the input position.

Parameters

text	The text surrounding the cursor position
cursor	Index in the text describing the cursor position
anchor	Index of the selection anchor, if no selection same as cursor

const

The text direction of input text.

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