Detailed Description

Creates and displays a popup-menu.

To show a popup-menu, you create one of these, add some items to it, then call its show() method, which returns the id of the item the user selects.

E.g.

void MyWidget::mouseDown (const MouseEvent& e)
{
    PopupMenu m;
    m.addItem (1, "item 1");
    m.addItem (2, "item 2");
 
    m.showMenuAsync (PopupMenu::Options(),
                     [] (int result)
                     {
                         if (result == 0)
                         {
                             // user dismissed the menu without picking anything
                         }
                         else if (result == 1)
                         {
                             // user picked item 1
                         }
                         else if (result == 2)
                         {
                             // user picked item 2
                         }
                     });
}

Submenus are easy too:

void MyWidget::mouseDown (const MouseEvent& e)
{
    PopupMenu subMenu;
    subMenu.addItem (1, "item 1");
    subMenu.addItem (2, "item 2");
 
    PopupMenu mainMenu;
    mainMenu.addItem (3, "item 3");
    mainMenu.addSubMenu ("other choices", subMenu);
 
    m.showMenuAsync (...);
}

Member Enumeration Documentation

◆ ColourIds

enum juce::PopupMenu::ColourIds

A set of colour IDs to use to change the colour of various aspects of the menu.

These constants can be used either via the LookAndFeel::setColour() method for the look and feel that is set for this menu with setLookAndFeel()

See also: setLookAndFeel, LookAndFeel::setColour, LookAndFeel::findColour

Enumerator
backgroundColourId	The colour to fill the menu's background with.
textColourId	The colour for normal menu item text, (unless the colour is specified when the item is added).
headerTextColourId	The colour for section header item text (see the addSectionHeader() method).
highlightedBackgroundColourId	The colour to fill the background of the currently highlighted menu item.
highlightedTextColourId	The colour to use for the text of the currently highlighted item.

Member Function Documentation

◆ addColouredItem() [1/2]

void juce::PopupMenu::addColouredItem	(	int	itemResultID,
		String	itemText,
		Colour	itemTextColour,
		bool	isEnabled,
		bool	isTicked,
		std::unique_ptr< Drawable >	iconToUse )

Appends a text item with a special colour.

This is the same as addItem(), but specifies a colour to use for the text, which will override the default colours that are used by the current look-and-feel. See addItem() for a description of the parameters.

◆ addColouredItem() [2/2]

void juce::PopupMenu::addColouredItem	(	int	itemResultID,
		String	itemText,
		Colour	itemTextColour,
		bool	isEnabled = true,
		bool	isTicked = false,
		const Image &	iconToUse = {} )

Appends a text item with a special colour.

This is the same as addItem(), but specifies a colour to use for the text, which will override the default colours that are used by the current look-and-feel. See addItem() for a description of the parameters.

◆ addColumnBreak()

void juce::PopupMenu::addColumnBreak ( )

Adds a column break to the menu, to help break it up into sections. Subsequent items will be placed in a new column, rather than being appended to the current column.

If a menu contains explicit column breaks, the menu will never add additional breaks.

◆ addCommandItem()

void juce::PopupMenu::addCommandItem	(	ApplicationCommandManager *	commandManager,
		CommandID	commandID,
		String	displayName = {},
		std::unique_ptr< Drawable >	iconToUse = {} )

Adds an item that represents one of the commands in a command manager object.

Parameters

commandManager	the manager to use to trigger the command and get information about it
commandID	the ID of the command
displayName	if this is non-empty, then this string will be used instead of the command's registered name
iconToUse	an optional Drawable object to use as the icon to the left of the item. The menu will take ownership of this drawable object and will delete it later when no longer needed

◆ addCustomItem() [1/2]

void juce::PopupMenu::addCustomItem	(	int	itemResultID,
		Component &	customComponent,
		int	idealWidth,
		int	idealHeight,
		bool	triggerMenuItemAutomaticallyWhenClicked,
		std::unique_ptr< const PopupMenu >	optionalSubMenu = nullptr,
		const String &	itemTitle = {} )

Appends a custom menu item that can't be used to trigger a result.

This will add a user-defined component to use as a menu item. The caller must ensure that the passed-in component stays alive until after the menu has been hidden.

If triggerMenuItemAutomaticallyWhenClicked is true, the menu itself will handle detection of a mouse-click on your component, and use that to trigger the menu ID specified in itemResultID. If this is false, the menu item can't be triggered, so itemResultID is not used.

itemTitle will be used as the fallback text for this item, and will be exposed to screen reader clients.

Note that native macOS menus do not support custom components.

◆ addCustomItem() [2/2]

void juce::PopupMenu::addCustomItem	(	int	itemResultID,
		std::unique_ptr< CustomComponent >	customComponent,
		std::unique_ptr< const PopupMenu >	optionalSubMenu = nullptr,
		const String &	itemTitle = {} )

Appends a custom menu item.

This will add a user-defined component to use as a menu item.

Note that native macOS menus do not support custom components.

itemTitle will be used as the fallback text for this item, and will be exposed to screen reader clients.

◆ addItem() [1/6]

void juce::PopupMenu::addItem	(	int	itemResultID,
		String	itemText,
		bool	isEnabled,
		bool	isTicked,
		const Image &	iconToUse )

Appends a new item with an icon.

Parameters

itemResultID	the number that will be returned from the show() method if the user picks this item. The value should never be zero, because that's used to indicate that the user didn't select anything.
itemText	the text to show.
isEnabled	if false, the item will be shown 'greyed-out' and can't be picked
isTicked	if true, the item will be shown with a tick next to it
iconToUse	if this is a valid image, it will be displayed to the left of the item.

See also: addSeparator, addColouredItem, addCustomItem, addSubMenu

◆ addItem() [2/6]

void juce::PopupMenu::addItem	(	int	itemResultID,
		String	itemText,
		bool	isEnabled,
		bool	isTicked,
		std::unique_ptr< Drawable >	iconToUse )

Appends a new item with an icon.

Parameters

itemResultID	the number that will be returned from the show() method if the user picks this item. The value should never be zero, because that's used to indicate that the user didn't select anything.
itemText	the text to show.
isEnabled	if false, the item will be shown 'greyed-out' and can't be picked
isTicked	if true, the item will be shown with a tick next to it
iconToUse	a Drawable object to use as the icon to the left of the item. The menu will take ownership of this drawable object and will delete it later when no longer needed

See also: addSeparator, addColouredItem, addCustomItem, addSubMenu

◆ addItem() [3/6]

void juce::PopupMenu::addItem	(	int	itemResultID,
		String	itemText,
		bool	isEnabled = true,
		bool	isTicked = false )

Appends a new text item for this menu to show.

Parameters

itemResultID	the number that will be returned from the show() method if the user picks this item. The value should never be zero, because that's used to indicate that the user didn't select anything.
itemText	the text to show.
isEnabled	if false, the item will be shown 'greyed-out' and can't be picked
isTicked	if true, the item will be shown with a tick next to it

See also: addSeparator, addColouredItem, addCustomItem, addSubMenu

◆ addItem() [4/6]

void juce::PopupMenu::addItem ( Item newItem )

Adds an item to the menu. You can call this method for full control over the item that is added, or use the other addItem helper methods if you want to pass arguments rather than creating an Item object.

◆ addItem() [5/6]

void juce::PopupMenu::addItem	(	String	itemText,
		bool	isEnabled,
		bool	isTicked,
		std::function< void()>	action )

Adds an item to the menu with an action callback.

◆ addItem() [6/6]

void juce::PopupMenu::addItem	(	String	itemText,
		std::function< void()>	action )

Adds an item to the menu with an action callback.

◆ addSectionHeader()

void juce::PopupMenu::addSectionHeader ( String title )

Adds a non-clickable text item to the menu. This is a bold-font items which can be used as a header to separate the items into named groups.

◆ addSeparator()

void juce::PopupMenu::addSeparator ( )

Appends a separator to the menu, to help break it up into sections. The menu class is smart enough not to display separators at the top or bottom of the menu, and it will replace multiple adjacent separators with a single one, so your code can be quite free and easy about adding these, and it'll always look ok.

◆ addSubMenu() [1/3]

void juce::PopupMenu::addSubMenu	(	String	subMenuName,
		PopupMenu	subMenu,
		bool	isEnabled,
		const Image &	iconToUse,
		bool	isTicked = false,
		int	itemResultID = 0 )

Appends a sub-menu with an icon.

If the menu that's passed in is empty, it will appear as an inactive item. If the itemResultID argument is non-zero, then the sub-menu item itself can be clicked to trigger it as a command.

◆ addSubMenu() [2/3]

void juce::PopupMenu::addSubMenu	(	String	subMenuName,
		PopupMenu	subMenu,
		bool	isEnabled,
		std::unique_ptr< Drawable >	iconToUse,
		bool	isTicked = false,
		int	itemResultID = 0 )

Appends a sub-menu with an icon.

If the menu that's passed in is empty, it will appear as an inactive item. If the itemResultID argument is non-zero, then the sub-menu item itself can be clicked to trigger it as a command.

The iconToUse parameter is a Drawable object to use as the icon to the left of the item. The menu will take ownership of this drawable object and will delete it later when no longer needed

◆ addSubMenu() [3/3]

void juce::PopupMenu::addSubMenu	(	String	subMenuName,
		PopupMenu	subMenu,
		bool	isEnabled = true )

Appends a sub-menu.

If the menu that's passed in is empty, it will appear as an inactive item. If the itemResultID argument is non-zero, then the sub-menu item itself can be clicked to trigger it as a command.

◆ clear()

void juce::PopupMenu::clear ( )

Resets the menu, removing all its items.

◆ containsAnyActiveItems()

bool juce::PopupMenu::containsAnyActiveItems ( ) const

noexcept

Returns true if the menu contains any items that can be used.

◆ containsCommandItem()

bool juce::PopupMenu::containsCommandItem ( int commandID ) const

Component * juce::PopupMenu::createWindow	(	const Options &	options,
		ApplicationCommandManager **	managerOfChosenCommand ) const

private

◆ dismissAllActiveMenus()

bool JUCE_CALLTYPE juce::PopupMenu::dismissAllActiveMenus ( )

static

Closes any menus that are currently open.

This might be useful if you have a situation where your window is being closed by some means other than a user action, and you'd like to make sure that menus aren't left hanging around.

		const Item *	itemToUse )

staticprivate

◆ setLookAndFeel()

void juce::PopupMenu::setLookAndFeel ( LookAndFeel * newLookAndFeel )

Specifies a look-and-feel for the menu and any sub-menus that it has.

This can be called before show() if you need a customised menu. Be careful not to delete the LookAndFeel object before the menu has been deleted.

◆ showMenuAsync() [1/3]

void juce::PopupMenu::showMenuAsync ( const Options & options )

Runs the menu asynchronously.
