Detailed Description

Represents the state of the mouse buttons and modifier keys.

This is used both by mouse events and by KeyPress objects to describe the state of keys such as shift, control, alt, etc.

Member Enumeration Documentation

◆ Flags

enum juce::ModifierKeys::Flags

Flags that represent the different keys.

Enumerator

ctrlModifier	CTRL key flag.
altModifier	ALT key flag.
leftButtonModifier	Left mouse button flag.
rightButtonModifier	Right mouse button flag.
middleButtonModifier	Middle mouse button flag.
commandModifier	Command key flag - on windows this is the same as the CTRL key flag.

ctrlAltCommandModifiers	Represents a combination of all the alt, ctrl and command key modifiers.

Constructor & Destructor Documentation

◆ ModifierKeys() [1/3]

juce::ModifierKeys::ModifierKeys ( )

default

Creates a ModifierKeys object with no flags set.

◆ ModifierKeys() [2/3]

juce::ModifierKeys::ModifierKeys ( int flags )

noexcept

Creates a ModifierKeys object from a raw set of flags.

Parameters

flags to represent the keys that are down

See also: shiftModifier, ctrlModifier, altModifier, leftButtonModifier, rightButtonModifier, commandModifier, popupMenuClickModifier

◆ ModifierKeys() [3/3]

juce::ModifierKeys::ModifierKeys ( const ModifierKeys & )

default

Creates a copy of another object.

Member Function Documentation

◆ getCurrentModifiers()

static ModifierKeys juce::ModifierKeys::getCurrentModifiers ( )

inlinestaticnoexcept

Creates a ModifierKeys object to represent the last-known state of the keyboard and mouse buttons.

This method is here for backwards compatibility and there's no need to call it anymore, you should use the public currentModifiers member directly.

◆ getCurrentModifiersRealtime()

static ModifierKeys juce::ModifierKeys::getCurrentModifiersRealtime ( )

staticnoexcept

Creates a ModifierKeys object to represent the current state of the keyboard and mouse buttons.

This method is here for backwards compatibility and you should call ComponentPeer::getCurrentModifiersRealtime() instead (which is what this method now does).

◆ getNumMouseButtonsDown()

int juce::ModifierKeys::getNumMouseButtonsDown ( ) const

noexcept

Returns the total number of mouse buttons that are down.

◆ getRawFlags()

int juce::ModifierKeys::getRawFlags ( ) const

inlinenoexcept

Returns the raw flags for direct testing.

References juce::gl::flags.

◆ isAltDown()

bool juce::ModifierKeys::isAltDown ( ) const

inlinenoexcept

Checks whether the ALT key's flag is set.

Referenced by juce::LassoComponent< SelectableItemType >::dragLasso().

◆ isAnyModifierKeyDown()

bool juce::ModifierKeys::isAnyModifierKeyDown ( ) const

inlinenoexcept

Tests for any of the modifier key flags.

◆ isAnyMouseButtonDown()

bool juce::ModifierKeys::isAnyMouseButtonDown ( ) const

inlinenoexcept

Tests for any of the mouse-button flags.

◆ isCommandDown()

bool juce::ModifierKeys::isCommandDown ( ) const

inlinenoexcept

Checks whether the 'command' key flag is set (or 'ctrl' on Windows/Linux).

This is a platform-agnostic way of checking for the operating system's preferred command-key modifier - so on the Mac it tests for the cmd key, on Windows/Linux, it's actually checking for the CTRL key.

Referenced by juce::SelectedItemSet< SelectableItemType >::addToSelectionBasedOnModifiers(), and juce::LassoComponent< SelectableItemType >::dragLasso().

◆ isCtrlDown()

bool juce::ModifierKeys::isCtrlDown ( ) const

inlinenoexcept

Checks whether the CTRL key's flag is set.

Remember that it's better to use the platform-agnostic routines to test for command-key and popup-menu modifiers.

See also: isCommandDown, isPopupMenu

◆ isLeftButtonDown()

bool juce::ModifierKeys::isLeftButtonDown ( ) const

inlinenoexcept

Checks whether the flag is set for the left mouse-button.

◆ isMiddleButtonDown()

bool juce::ModifierKeys::isMiddleButtonDown ( ) const

inlinenoexcept

◆ isPopupMenu()

bool juce::ModifierKeys::isPopupMenu ( ) const

inlinenoexcept

Checks whether the user is trying to launch a pop-up menu.

This checks for platform-specific modifiers that might indicate that the user is following the operating system's normal method of showing a pop-up menu.

So on Windows/Linux, this method is really testing for a right-click. On the Mac, it tests for either the CTRL key being down, or a right-click.

Referenced by juce::SelectedItemSet< SelectableItemType >::addToSelectionOnMouseDown().

◆ isRightButtonDown()

bool juce::ModifierKeys::isRightButtonDown ( ) const

inlinenoexcept

Checks whether the flag is set for the right mouse-button.

Note that for detecting popup-menu clicks, you should be using isPopupMenu() instead, as this is platform-independent (and makes your code more explanatory too).

◆ isShiftDown()

bool juce::ModifierKeys::isShiftDown ( ) const

inlinenoexcept

Checks whether the shift key's flag is set.

Referenced by juce::SelectedItemSet< SelectableItemType >::addToSelectionBasedOnModifiers(), and juce::LassoComponent< SelectableItemType >::dragLasso().

◆ operator!=()

bool juce::ModifierKeys::operator!= ( const ModifierKeys other ) const

inlinenoexcept

References juce::gl::flags.

◆ operator=()

ModifierKeys& juce::ModifierKeys::operator= ( const ModifierKeys & )

default

Copies this object from another one.

◆ operator==()

bool juce::ModifierKeys::operator== ( const ModifierKeys other ) const

inlinenoexcept

References juce::gl::flags.

◆ testFlags()

bool juce::ModifierKeys::testFlags ( int flagsToTest ) const

inlinenoexcept

Tests a combination of flags and returns true if any of them are set.

References juce::gl::flags.

◆ withFlags()

JUCE_NODISCARD ModifierKeys juce::ModifierKeys::withFlags ( int rawFlagsToSet ) const

inlinenoexcept

References juce::gl::flags.

◆ withOnlyMouseButtons()

JUCE_NODISCARD ModifierKeys juce::ModifierKeys::withOnlyMouseButtons ( ) const

inlinenoexcept

Returns a copy of only the mouse-button flags.

References juce::gl::flags.

◆ withoutFlags()

JUCE_NODISCARD ModifierKeys juce::ModifierKeys::withoutFlags ( int rawFlagsToClear ) const

inlinenoexcept

References juce::gl::flags.

◆ withoutMouseButtons()

JUCE_NODISCARD ModifierKeys juce::ModifierKeys::withoutMouseButtons ( ) const

inlinenoexcept

Returns a copy of only the non-mouse flags.

References juce::gl::flags.
