Detailed Description

Represents a key press, including any modifier keys that are needed.

E.g. a KeyPress might represent CTRL+C, SHIFT+ALT+H, Spacebar, Escape, etc.

Constructor & Destructor Documentation

◆ KeyPress() [1/4]

KeyPress::KeyPress ( )

default

Creates an (invalid) KeyPress.

See also: isValid

◆ ~KeyPress()

KeyPress::~KeyPress ( )

default

Destructor.

◆ KeyPress() [2/4]

KeyPress::KeyPress	(	int	keyCode,
		ModifierKeys	modifiers,
		juce_wchar	textCharacter )

noexcept

Creates a KeyPress for a key and some modifiers.

e.g. CTRL+C would be: KeyPress ('c', ModifierKeys::ctrlModifier, 0) SHIFT+Escape would be: KeyPress (KeyPress::escapeKey, ModifierKeys::shiftModifier, 0)

Parameters

keyCode	a code that represents the key - this value must be one of special constants listed in this class, or an 8-bit character code such as a letter (case is ignored), digit or a simple key like "," or ".". Note that this isn't the same as the textCharacter parameter, so for example a keyCode of 'a' and a shift-key modifier should have a textCharacter value of 'A'.
modifiers	the modifiers to associate with the keystroke
textCharacter	the character that would be printed if someone typed this keypress into a text editor. This value may be null if the keypress is a non-printing character

See also: getKeyCode, isKeyCode, getModifiers

◆ KeyPress() [3/4]

KeyPress::KeyPress ( int keyCode )

explicitnoexcept

Creates a keypress with a keyCode but no modifiers or text character.

◆ KeyPress() [4/4]

KeyPress::KeyPress ( const KeyPress & )

default

Creates a copy of another KeyPress.

Member Function Documentation

◆ operator=()

KeyPress & KeyPress::operator= ( const KeyPress & )

default

Copies this KeyPress from another one.

◆ operator==() [1/2]

bool KeyPress::operator== ( const KeyPress & other ) const

noexcept

Compares two KeyPress objects.

◆ operator!=() [1/2]

bool KeyPress::operator!= ( const KeyPress & other ) const

noexcept

Compares two KeyPress objects.

◆ operator==() [2/2]

bool KeyPress::operator== ( int keyCode ) const

noexcept

Returns true if this keypress is for the given keycode without any modifiers.

◆ operator!=() [2/2]

bool KeyPress::operator!= ( int keyCode ) const

noexcept

Returns true if this keypress is not for the given keycode without any modifiers.

◆ isValid()

bool KeyPress::isValid ( ) const

noexcept

Returns true if this is a valid KeyPress.

A null keypress can be created by the default constructor, in case it's needed.

◆ getKeyCode()

int KeyPress::getKeyCode ( ) const

noexcept

Returns the key code itself.

This will either be one of the special constants defined in this class, or an 8-bit character code.

◆ getModifiers()

ModifierKeys KeyPress::getModifiers ( ) const

noexcept

Returns the key modifiers.

See also: ModifierKeys

◆ getTextCharacter()

juce_wchar KeyPress::getTextCharacter ( ) const

noexcept

Returns the character that is associated with this keypress.

This is the character that you'd expect to see printed if you press this keypress in a text editor or similar component.

◆ isKeyCode()

bool KeyPress::isKeyCode ( int keyCodeToCompare ) const

noexcept

Checks whether the KeyPress's key is the same as the one provided, without checking the modifiers.

The values for key codes can either be one of the special constants defined in this class, or an 8-bit character code.

See also: getKeyCode

Referenced by TextEditorKeyMapper< CallbackClass >::invokeKeyFunction().

◆ createFromDescription()

static KeyPress KeyPress::createFromDescription ( const String & textVersion )

static

Converts a textual key description to a KeyPress.

This attempts to decode a textual version of a keypress, e.g. "ctrl + c" or "spacebar".

This isn't designed to cope with any kind of input, but should be given the strings that are created by the getTextDescription() method.

If the string can't be parsed, the object returned will be invalid.

See also: getTextDescription

◆ getTextDescription()

String KeyPress::getTextDescription ( ) const

Creates a textual description of the key combination.

e.g. "ctrl + c" or "delete".

To store a keypress in a file, use this method, along with createFromDescription() to retrieve it later.

◆ getTextDescriptionWithIcons()

String KeyPress::getTextDescriptionWithIcons ( ) const

Creates a textual description of the key combination, using unicode icon symbols if possible.

On OSX, this uses the Apple symbols for command, option, shift, etc, instead of the textual modifier key descriptions that are returned by getTextDescription()

◆ isCurrentlyDown()

bool KeyPress::isCurrentlyDown ( ) const

Checks whether the user is currently holding down the keys that make up this KeyPress.

Note that this will return false if any extra modifier keys are down - e.g. if the keypress is CTRL+X and the user is actually holding CTRL+ALT+x then it will be false.

◆ isKeyCurrentlyDown()

static bool KeyPress::isKeyCurrentlyDown ( int keyCode )

static

Checks whether a particular key is held down, irrespective of modifiers.

The values for key codes can either be one of the special constants defined in this class, or an 8-bit character code.
