Constructor Detail

• Dropdown

  Dropdown(DropdownProperties properties, Vec2<Unit> at, Vec2<Unit> size, Unit.Pixel heightBeforeScrolls, Integer default, Dropdown.Entry entries)

Method Detail

• getProperties

   DropdownProperties getProperties()

• getSelected

   final Dropdown.Entry getSelected()

• getDropdown

   final Layout getDropdown()

• getActive

   final Boolean getActive()

• getDefault

   final Integer getDefault()

• accept

   Boolean accept(FocusedEvent event)

  Accept a FocusedEvent and handle it.

  Returns:

  true to consume the event (only applicable to FocusedEvent.Gained and FocusedEvent.Lost

• accept

   Boolean accept(Event event)

  called when this drawable receives an event.

  make sure to call Drawable.accept!

  Returns:

  true if the event should be consumed (cancelled so no more handlers are called), false otherwise.

• setup

   Unit setup(Renderer renderer, PolyUI polyUI)

  give this a renderer reference and a PolyUI reference.

  You can also use this method to do some calculations (such as text widths) that are not dependent on other sizes.

  If you need a method that has access to component's sizes, see here or here (if you are operating on yourself only).

  this method is called once, and only once.

• close

   final Unit close()

• open

   final Unit open()

• render

   Unit render()

  Render the children of this component.

  you must call super.render()!

• calculateSize

   Vec2<Unit> calculateSize()

  Implement this function to return the size of this drawable, if no size is specified during construction.

  This should be so that if the drawable can determine its own size (for example, it is an image), then the size parameter in the constructor can be omitted using:

  size: Vec2<org.polyfrost.polyui.unit.Unit>? = null; and this method needs to be implemented!

  Otherwise, the size parameter in the constructor must be specified.

• calculateBounds

   Unit calculateBounds()

  Calculate the position and size of this drawable. Make sure to call doDynamicSize in this method to avoid issues with sizing.

  This method is called once the layout is populated for children and component, and when a recalculation is requested.

  The value of layout's bounds will be updated after this method is called, so do not use layout's bounds as an updated value in this method.

• onInitComplete

   Unit onInitComplete()

  This function is called when initialization of a drawable is complete, so it has been fully calculated.

  This function is called once, and only once.

  0.19.0

• default

   final Unit default()

• from

   final static Array<out Dropdown.Entry> from(Class<?> enumClass)

  Constructs a dropdown from an enum class. This method will look at the first field in the enum entries, and if it is a String it will extract that; and use that as the name.

  Otherwise, it will use the name of the enum entry as it is declared in the source code.

  Since:

  0.19.0

• from

   final static Array<out Dropdown.Entry> from(Array<out Object> values)

  Constructs a dropdown from an array of values. This method will call Any.toString on each value to get the name.

  Since:

  0.19.0
