Member Function Documentation

addListener()

void juce::MarkerList::addListener

(

Listener *

listener

)

Registers a listener that will be called when the markers are changed.

getMarker() [1/2]

const Marker* juce::MarkerList::getMarker ( const String &  name ) const

noexcept

Returns a named marker, or nullptr if no such name is found.

Note that name comparisons are case-sensitive.

getMarker() [2/2]

const Marker* juce::MarkerList::getMarker ( int  index ) const

noexcept

Returns one of the markers in the list, by its index.

getMarkerByName()

Marker* juce::MarkerList::getMarkerByName ( const String &  name ) const

privatenoexcept

getMarkerPosition()

double juce::MarkerList::getMarkerPosition	(	const Marker &	marker,
		Component *	parentComponent
	)		const

Evaluates the given marker and returns its absolute position.

The parent component must be supplied in case the marker's expression refers to the size of its parent component.

getNumMarkers()

int juce::MarkerList::getNumMarkers ( ) const

noexcept

Returns the number of markers in the list.

markersHaveChanged()

void juce::MarkerList::markersHaveChanged

(

)

Synchronously calls markersChanged() on all the registered listeners.

operator!=()

bool juce::MarkerList::operator!= ( const MarkerList &  ) const

noexcept

Returns true if not all the markers in these two lists match exactly.

operator=()

MarkerList& juce::MarkerList::operator=

(

const MarkerList &

)

Copies another marker list to this one.

operator==()

bool juce::MarkerList::operator== ( const MarkerList &  ) const

noexcept

Returns true if all the markers in these two lists match exactly.

removeListener()

void juce::MarkerList::removeListener

(

Listener *

listener

)

Deregisters a previously-registered listener.

removeMarker() [1/2]

void juce::MarkerList::removeMarker

(

const String &

name

)

Deletes the marker with the given name.

removeMarker() [2/2]

void juce::MarkerList::removeMarker

(

int

index

)

Deletes the marker at the given list index.

setMarker()

void juce::MarkerList::setMarker	(	const String &	name,
		const RelativeCoordinate &	position
	)

Sets the position of a marker.

If the name already exists, then the existing marker is moved; if it doesn't exist, then a new marker is added.
