Detailed Description

A convertor which maps between key sequences pressed by the user and the character strings which should be sent to the terminal and commands which should be invoked when those character sequences are pressed.

Konsole supports multiple keyboard translators, allowing the user to specify the character sequences which are sent to the terminal when particular key sequences are pressed.

A key sequence is defined as a key code, associated keyboard modifiers (Shift,Ctrl,Alt,Meta etc.) and state flags which indicate the state which the terminal must be in for the key sequence to apply.

Member Enumeration Documentation

◆ Command

enum KeyboardTranslator::Command

This enum describes commands which are associated with particular key sequences.

Enumerator
NoCommand	Indicates that no command is associated with this command sequence.
SendCommand	TODO Document me.
ScrollPageUpCommand	Scroll the terminal display up one page.
ScrollPageDownCommand	Scroll the terminal display down one page.
ScrollLineUpCommand	Scroll the terminal display up one line.
ScrollLineDownCommand	Scroll the terminal display down one line.
ScrollLockCommand	Toggles scroll lock mode.
EraseCommand	Echos the operating system specific erase character.

Definition at line 170 of file KeyboardTranslator.h.

◆ State

enum KeyboardTranslator::State

The meaning of a particular key sequence may depend upon the state which the terminal emulation is in.

Therefore findEntry() may return a different Entry depending upon the state flags supplied.

This enum describes the states which may be associated with with a particular entry in the keyboard translation entry.

Enumerator
NoState	Indicates that no special state is active.
NewLineState	TODO More documentation.
AnsiState	Indicates that the terminal is in 'Ansi' mode. TODO: More documentation
CursorKeysState	TODO More documentation.
AlternateScreenState	Indicates that the alternate screen ( typically used by interactive programs such as screen or vim ) is active.
AnyModifierState	Indicates that any of the modifier keys is active.

Constructor & Destructor Documentation

◆ KeyboardTranslator()

KeyboardTranslator::KeyboardTranslator ( const QString & name )

Constructs a new keyboard translator with the given name.

Definition at line 802 of file KeyboardTranslator.cpp.

Member Function Documentation

◆ addEntry()

void KeyboardTranslator::addEntry ( const Entry & entry )

Adds an entry to this keyboard translator's table.

Entries can be looked up according to their key sequence using findEntry()

Definition at line 829 of file KeyboardTranslator.cpp.

References _entries, and KeyboardTranslator::Entry::keyCode().

Referenced by KeyboardTranslatorManager::loadTranslator().

◆ description()

QString KeyboardTranslator::description ( ) const

Returns the descriptive name of this keyboard translator.

Definition at line 811 of file KeyboardTranslator.cpp.

References _description.

Referenced by KeyboardTranslatorManager::saveTranslator(), and setDescription().

◆ entries()

QList< KeyboardTranslator::Entry > KeyboardTranslator::entries ( ) const

Returns a list of all entries in the translator.

Definition at line 824 of file KeyboardTranslator.cpp.

References _entries.

Referenced by KeyboardTranslatorManager::saveTranslator().

◆ findEntry()

KeyboardTranslator::Entry KeyboardTranslator::findEntry	(	int	keyCode,
		Qt::KeyboardModifiers	modifiers,
		States	state = `NoState`
	)		const

Looks for an entry in this keyboard translator which matches the given key code, keyboard modifiers and state flags.

Returns the matching entry if found or a null Entry otherwise ( ie. entry.isNull() will return true )

Parameters

keyCode	A key code from the Qt::Key enum
modifiers	A combination of modifiers
state	Optional flags which specify the current state of the terminal

◆ name()

QString KeyboardTranslator::name ( void ) const

Returns the name of this keyboard translator.

Definition at line 819 of file KeyboardTranslator.cpp.

◆ removeEntry()

void KeyboardTranslator::removeEntry ( const Entry & entry )

Removes an entry from the table.

◆ replaceEntry()

void KeyboardTranslator::replaceEntry	(	const Entry &	existing,
		const Entry &	replacement
	)

Replaces an entry in the translator.

If the existing entry is null, then this is equivalent to calling addEntry(replacement)
