this

Example

import { ShapePanel } from './ShapePanel';
interface ShapePanelOptions {}
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
    .useFieldConfig({})
    ...
    ...
    .setDataSupport({
      annotations: true,
      alertStates: true,
    });

setDefaults method

Signature

setDefaults(defaults: TOptions): this;

Parameters

This function is called before the panel first loads if the current version is different than the version that was saved.

This is a good place to support any changes to the options model

Signature

setMigrationHandler(handler: PanelMigrationHandler<TOptions>): this;

Parameters

Returns:

this

setNoPadding method

Signature

setNoPadding(): this;

Returns:

this

Returns:

this

setPanelOptions method

Enables panel options editor creation

interface ShapePanelOptions {}
// when plugin should use all standard options

// when plugin should only display specific standard options
// note, that options will be displayed in the order they are provided
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
 .useFieldConfig({
   standardOptions: [FieldConfigProperty.Min, FieldConfigProperty.Max]
  });
// when standard option's default value needs to be provided
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
 .useFieldConfig({
   standardOptions: [FieldConfigProperty.Min, FieldConfigProperty.Max],
   standardOptionsDefaults: {
     [FieldConfigProperty.Min]: 20,
     [FieldConfigProperty.Max]: 100
   }
 });
// when custom field config options needs to be provided
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
 .useFieldConfig({
   useCustomConfig: builder => {
     builder
      .addNumberInput({
        id: 'shapeBorderWidth',
        name: 'Border width',
