Detailed Description

Allows you to iterate through the items in a pop-up menu, and examine their properties.

To use this, just create one and repeatedly call its next() method. When this returns true, all the member variables of the iterator are filled-out with information describing the menu item. When it returns false, the end of the list has been reached.

Constructor & Destructor Documentation

MenuItemIterator()

juce::PopupMenu::MenuItemIterator::MenuItemIterator	(	const PopupMenu &	menu,
		bool	searchRecursively = false
	)

Be careful not to add any items to a menu while it is being iterated, or things could get out of step.

Parameters

menu	the menu that needs to be scanned
searchRecursively	if true, all submenus will be recursed into to do an exhaustive search

~MenuItemIterator()

juce::PopupMenu::MenuItemIterator::~MenuItemIterator

(

getItem()

Item& juce::PopupMenu::MenuItemIterator::getItem ( ) const

noexcept

next()

bool juce::PopupMenu::MenuItemIterator::next

(

)

Returns true if there is another item, and sets up all this object's member variables to reflect that item's properties.
