◆ MultiChoicePropertyComponent() [1/2]

MultiChoicePropertyComponent::MultiChoicePropertyComponent ( const Value & valueToControl,
const String & propertyName,
const StringArray & choices,
const Array< var > & correspondingValues,
int maxChoices = -1 )

Creates the component.

Note that the underlying var object that the Value refers to must be an array.

Parameters
valueToControlthe value that the ToggleButtons will read and control
propertyNamethe name of the property
choicesthe list of possible values that will be represented
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
maxChoicesthe maximum number of values which can be selected at once. The default of -1 will not limit the number that can be selected

◆ MultiChoicePropertyComponent() [2/2]

MultiChoicePropertyComponent::MultiChoicePropertyComponent ( const ValueTreePropertyWithDefault & valueToControl,
const String & propertyName,
const StringArray & choices,
const Array< var > & correspondingValues,
int maxChoices = -1 )

Creates the component using a ValueTreePropertyWithDefault object.

This will select the default options.

Parameters
valueToControlthe ValueTreePropertyWithDefault object that contains the Value object that the ToggleButtons will read and control.
propertyNamethe name of the property
choicesthe list of possible values that will be represented
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
maxChoicesthe maximum number of values which can be selected at once. The default of -1 will not limit the number that can be selected

Member Function Documentation

◆ isExpanded()

bool MultiChoicePropertyComponent::isExpanded ( ) const
noexcept

Returns true if the list of options is expanded.

◆ isExpandable()

bool MultiChoicePropertyComponent::isExpandable ( ) const
noexcept

Returns true if the list of options has been truncated and can be expanded.

◆ setExpanded()

void MultiChoicePropertyComponent::setExpanded ( bool expanded)
noexcept

Expands or shrinks the list of options if they are not all visible.

N.B. This will just set the preferredHeight value of the PropertyComponent and attempt to call PropertyPanel::resized(), so if you are not displaying this object in a PropertyPanel then you should use the onHeightChange callback to resize it when the height changes.

◆ paint()

void MultiChoicePropertyComponent::paint ( Graphics & g)
overridevirtual

Components can override this method to draw their content.

The paint() method gets called when a region of a component needs redrawing, either because the component's repaint() method has been called, or because something has happened on the screen that means a section of a window needs to be redrawn.

Any child components will draw themselves over whatever this method draws. If you need to paint over the top of your child components, you can also implement the paintOverChildren() method to do this.

If you want to cause a component to redraw itself, this is done asynchronously - calling the repaint() method marks a region of the component as "dirty", and the paint() method will automatically be called sometime later, by the message thread, to paint any bits that need refreshing. In JUCE (and almost all modern UI frameworks), you never redraw something synchronously.

You should never need to call this method directly - to take a snapshot of the component you could use createComponentSnapshot() or paintEntireComponent().

Parameters
gthe graphics context that must be used to do the drawing operations.

◆ resized()

void MultiChoicePropertyComponent::resized ( )
overridevirtual

Called when this component's size has been changed.

A component can implement this method to do things such as laying out its child components when its width or height changes.

The method is called synchronously as a result of the setBounds or setSize methods, so repeatedly changing a components size will repeatedly call its resized method (unlike things like repainting, where multiple calls to repaint are coalesced together).

If the component is a top-level window on the desktop, its size could also be changed by operating-system factors beyond the application's control.

◆ refresh()

void MultiChoicePropertyComponent::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 PropertyComponent.

◆ onHeightChange

std::function<void()> MultiChoicePropertyComponent::onHeightChange

You can assign a lambda to this callback object to have it called when the height of this component changes in response to being expanded/collapsed.
