Hi,
when setting up your CustomPalette (following along the example) you can override the _update
function:
...
export default class CustomPalette {
constructor(create, elementFactory, palette, translate) {
this.create = create;
this.elementFactory = elementFactory;
this.translate = translate;
palette.registerProvider(this);
palette._update = function () {
// ...
}
}
getPaletteEntries(element) {
// ...
}
}
...
