Detailed Description

Represents a generic Resource for a text input object.

This class does not directly correspond to a Wayland resource, but is a generic contract for any interface which implements a text input, e.g. the unstable wl_text_input interface.

It does not expose the actual interface to cover up the fact that the interface is unstable and might change. If one needs to know the actual used protocol, use the method interfaceVersion.

A TextInputInterface gets created by the TextInputManagerInterface. The individual instances are not exposed directly. The SeatInterface provides access to the currently active TextInputInterface. This is evaluated automatically based on which SurfaceInterface has keyboard focus.

See also: TextInputManagerInterface; SeatInterface

Since: 5.23

ContentHint allows to modify the behavior of the text input.

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
TitleCase	prefer casing for titles and headings (can be language dependent)
HiddenText	characters should be hidden
SensitiveData	typed text should not be stored
Latin	just latin characters should be entered
MultiLine	the text input is multi line

Definition at line 100 of file textinput_interface.h.

enum KWayland::Server::TextInputInterface::ContentPurpose : uint32_t

The ContentPurpose allows to specify the primary purpose of a text input.

This allows an input method to show special purpose input panels with extra characters or to disallow some characters.

Enumerator
Normal	default input, allowing all characters
Alpha	allow only alphabetic characters
Digits	allow only digits
Number	input a number (including decimal separator and sign)

Email	input an email address
Name	input a name of a person
Password	input a password
Date	input a date
Time	input a time
DateTime	input a date and time
Terminal	input for a terminal

Member Function Documentation

void KWayland::Server::TextInputInterface::commit ( const QByteArray & text )

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 (preEdit). It could be also an empty text when some text should be removed (see deleteSurroundingText) or when the input cursor should be moved (see cursorPosition).

Any previously set composing text should be removed.

Parameters

text	The utf8-encoded text to be inserted into the editor widget

See also: preEdit; deleteSurroundingText

Definition at line 102 of file textinput_interface.cpp.

TextInputInterface::ContentPurpose KWayland::Server::TextInputInterface::contentPurpose ( ) const

See also: contentTypeChanged

Definition at line 108 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::contentTypeChanged ( )

signal

Emitted when the contentPurpose and/or contentHints changes.

signal

See also: cursorRectangle

void KWayland::Server::TextInputInterface::deleteSurroundingText	(	quint32	beforeLength,
		quint32	afterLength
	)

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

The Client processes this event together with the commit string

Parameters

beforeLength	length of text before current cursor position.
afterLength	length of text after current cursor position.

See also: commit

Definition at line 157 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::enabledChanged ( )

signal

Emitted whenever this TextInputInterface gets enabled or disabled for a SurfaceInterface.

See also: isEnabled; surface

TextInputInterfaceVersion KWayland::Server::TextInputInterface::interfaceVersion ( ) const

Returns: The interface version used by this TextInputInterface

Definition at line 204 of file textinput_interface.cpp.

bool KWayland::Server::TextInputInterface::isEnabled ( ) const

Returns: Whether the TextInputInterface is currently enabled for a SurfaceInterface.

See also: surface; enabledChanged

Definition at line 222 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::preEdit	(	const QByteArray &	text,
		const QByteArray &	commitText
	)

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

Parameters

text	The new utf8-encoded pre-edit text
commitText	Utf8-encoded text to replace preedit text on reset

See also: commit; preEditCursor

Definition at line 132 of file textinput_interface.cpp.

QByteArray KWayland::Server::TextInputInterface::preferredLanguage ( ) const

The preferred language as a RFC-3066 format language tag.

This can be used by the server to show a language specific virtual keyboard layout.

See also: preferredLanguageChanged

Definition at line 96 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::preferredLanguageChanged ( const QByteArray & language )

signal

Emitted whenever the preferred language changes.

See also: preferredLanguage

void KWayland::Server::TextInputInterface::requestHideInputPanel ( )

signal

Requests input panels (virtual keyboard) to hide.

See also: requestShowInputPanel

void KWayland::Server::TextInputInterface::requestReset ( )

signal

Invoked by the client when the input state should be reset, for example after the text was changed outside of the normal input method flow.

void KWayland::Server::TextInputInterface::requestShowInputPanel ( )

signal

Requests input panels (virtual keyboard) to show.

See also: requestHideInputPanel

void KWayland::Server::TextInputInterface::setCursorPosition	(	qint32	index,

The overlappedSurfaceArea defines the area overlapped by the input panel (virtual keyboard) on the SurfaceInterface having the text focus in surface local coordinates.

Parameters

visible	Whether the input panel is currently visible
overlappedSurfaceArea	The overlapping area in surface local coordinates

Definition at line 181 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::setLanguage ( const QByteArray & languageTag )

Definition at line 193 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::setPreEditCursor ( qint32 index )

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.

The Client applies the index together with preEdit.

Parameters

index The cursor position relative to the start of the composing text

See also: preEdit

Definition at line 175 of file textinput_interface.cpp.

void KWayland::Server::TextInputInterface::setTextDirection ( Qt::LayoutDirection direction )
