Syntax
public sealed class ScyllaPresetSelector : VisualElement, IEventHandler, IResolvedStyle, ITransform, ITransitionAnimations, IExperimentalFeatures, IVisualElementScheduler, ICustomStyle
Remarks

The inner DropdownField fills the available width via style.flexGrow = 1. Callers can add the element to any flex row and the dropdown will fill the remaining space after sibling elements.

Use SetSelectedIndexWithoutNotify(int) to programmatically select a preset during initialization without triggering PresetSelected.

Constructors

ScyllaPresetSelector(string, IList<string>, int)

Creates a new preset selector with the given label, preset list, and initial selection. Fires PresetSelected whenever the user changes the dropdown value.

Declaration
public ScyllaPresetSelector(string label, IList<string> presets, int initialIndex = 0)
Parameters
Type Name Description
string label

Label text displayed to the left of the dropdown by the UnityEngine.UIElements.DropdownField. Pass an empty string for a label-free control.
IList<string> presets

The list of preset names to populate the dropdown. A defensive copy is made, so mutating the source list after construction has no effect; use SetPresets(IList<string>) to update the choices.
int initialIndex

Zero-based index of the preset selected on construction. Default: 0.

Properties

SelectedIndex

Gets the zero-based index of the currently selected preset within the current choices list.

Declaration
public int SelectedIndex { get; }
Property Value
Type Description
int

The selected index, or -1 when no preset is selected.

SelectedPreset

Gets the name of the currently selected preset, as shown in the dropdown.

Declaration
public string SelectedPreset { get; }
Property Value
Type Description
string

The selected preset name, or an empty string when the preset list is empty.

Methods

SetPresets(IList<string>)

Replaces the list of available presets. A defensive copy is made from presets. The current selection is cleared if it no longer exists in the new list.

Declaration
public void SetPresets(IList<string> presets)
Parameters
Type Name Description
IList<string> presets

The new list of preset names. Must not be null.

SetSelectedIndexWithoutNotify(int)

Programmatically selects the preset at index without raising PresetSelected. Use this during initialization to restore a saved selection without side effects.

Declaration
public void SetSelectedIndexWithoutNotify(int index)
Parameters
Type Name Description
int index

Zero-based index of the preset to select. If out of range the selection is set to an empty string.

Events

PresetSelected

Raised when the user selects a different preset in the dropdown. The argument is the newly selected preset name. Not fired when the selection is changed programmatically via SetSelectedIndexWithoutNotify(int).

Declaration
public event Action<string> PresetSelected
Event Type
Type Description
Action<string>
