Detailed Description

A PropertyComponent that shows its value as a combo box.

This type of property component contains a list of options and has a combo box to choose one.

Your subclass's constructor must add some strings to the choices StringArray and these are shown in the list.

The getIndex() method will be called to find out which option is the currently selected one. If you call refresh() it will call getIndex() to check whether the value has changed, and will update the combo box if needed.

If the user selects a different item from the list, setIndex() will be called to let your class process this.

Constructor & Destructor Documentation

◆ ChoicePropertyComponent() [1/5]

juce::ChoicePropertyComponent::ChoicePropertyComponent ( const String & name,
const StringArray & choiceList,
const Array< var > & correspondingValues )
private

Delegating constructor.

◆ ChoicePropertyComponent() [2/5]

juce::ChoicePropertyComponent::ChoicePropertyComponent ( const String & propertyName)
protected

Creates the component. Your subclass's constructor must add a list of options to the choices member variable.

◆ ChoicePropertyComponent() [3/5]

juce::ChoicePropertyComponent::ChoicePropertyComponent ( const Value & valueToControl,
const String & propertyName,
const StringArray & choices,
const Array< var > & correspondingValues )

Creates the component.

Note that if you call this constructor then you must use the Value to interact with the index, and you can't override the class with your own setIndex or getIndex methods. If you want to use those methods, call the other constructor instead.

Parameters
valueToControlthe value that the combo box will read and control
propertyNamethe name of the property
choicesthe list of possible values that the drop-down list will contain
correspondingValuesa list of values corresponding to each item in the 'choices' StringArray. These are the values that will be read and written to the valueToControl value. This array must contain the same number of items as the choices array

◆ ChoicePropertyComponent() [4/5]

juce::ChoicePropertyComponent::ChoicePropertyComponent ( const ValueTreePropertyWithDefault & valueToControl,
const String & propertyName,
const StringArray & choices,
const Array< var > & correspondingValues )

Creates the component using a ValueTreePropertyWithDefault object. This will add an item to the ComboBox for the default value with an ID of -1.

Parameters
valueToControlthe ValueTreePropertyWithDefault object that contains the Value object that the combo box will read and control.
propertyNamethe name of the property
choicesthe list of possible values that the drop-down list will contain
correspondingValuesa list of values corresponding to each item in the 'choices' StringArray. These are the values that will be read and written to the valueToControl value. This array must contain the same number of items as the choices array

◆ ChoicePropertyComponent() [5/5]

juce::ChoicePropertyComponent::ChoicePropertyComponent ( const ValueTreePropertyWithDefault & valueToControl,
const String & propertyName )

Creates the component using a ValueTreePropertyWithDefault object, adding an item to the ComboBox for the default value with an ID of -1 as well as adding separate "Enabled" and "Disabled" options.

This is useful for simple on/off choices that also need a default value.

Member Function Documentation

◆ changeIndex()

void juce::ChoicePropertyComponent::changeIndex ( )
private

◆ getChoices()

const StringArray & juce::ChoicePropertyComponent::getChoices ( ) const

Returns the list of options.

◆ getIndex()

int juce::ChoicePropertyComponent::getIndex ( ) const
virtual

Returns the index of the item that should currently be shown. This is the index of the item in the choices StringArray that will be shown.

◆ initialiseComboBox()

void juce::ChoicePropertyComponent::initialiseComboBox ( const Value & v)
private

◆ refresh()

void juce::ChoicePropertyComponent::refresh ( )
overridevirtual

Updates the property component if the item it refers to has changed.

A subclass must implement this method, and other objects may call it to force it to refresh itself.

The subclass should be economical in the amount of work is done, so for example it should check whether it really needs to do a repaint rather than just doing one every time this method is called, as it may be called when the value being displayed hasn't actually changed.

Implements juce::PropertyComponent.

◆ refreshChoices() [1/2]

void juce::ChoicePropertyComponent::refreshChoices ( )
private

◆ refreshChoices() [2/2]

void juce::ChoicePropertyComponent::refreshChoices ( const String & defaultString)
private

◆ setIndex()

void juce::ChoicePropertyComponent::setIndex ( int newIndex)
virtual

Called when the user selects an item from the combo box.

Your subclass must use this callback to update the value that this component represents. The index is the index of the chosen item in the choices StringArray.

Member Data Documentation

◆ choices

StringArray juce::ChoicePropertyComponent::choices
protected

The list of options that will be shown in the combo box.

Your subclass must populate this array in its constructor. If any empty strings are added, these will be replaced with horizontal separators (see ComboBox::addSeparator() for more info).

◆ comboBox

ComboBox juce::ChoicePropertyComponent::comboBox
private

◆ isCustomClass

bool juce::ChoicePropertyComponent::isCustomClass = false
private

◆ value

ValueTreePropertyWithDefault juce::ChoicePropertyComponent::value
private
