Gantt settings transforms

Use this guide when you need to format values in Gantt hover tooltips through schedule.* settings.

What settings can control

For Gantt tooltip fields, settings can define label, template, hidden, and order directly.

transform is different: the settings API stores data, not executable JavaScript. Because of that, the panel resolves only safe declarative descriptors before calling createConfig(...) for @mes/aps.

Supported descriptor: valueMap

The panel currently supports transform.type = valueMap for:

• operationTooltipConfig
• constraintsTooltipConfig
• supplyTooltipConfig

Equivalent nested shape after useSettingsFind().mapSettings({ prefix: 'schedule' }):

{
  "operationTooltipConfig": {
    "late": {
      "label": "Опаздывает",
      "transform": {
        "type": "valueMap",
        "values": {
          "true": "Да",
          "false": "Нет"
        },
        "fallback": "Не задано"
      }
    }
  }
}

Settings API example:

schedule.operationTooltipConfig.late.label = "Опаздывает"
schedule.operationTooltipConfig.late.transform.type = "valueMap"
schedule.operationTooltipConfig.late.transform.values.true = "Да"
schedule.operationTooltipConfig.late.transform.values.false = "Нет"
schedule.operationTooltipConfig.late.transform.fallback = "Не задано"

schedule.operationTooltipConfig.locked.label = "Заблокирована"
schedule.operationTooltipConfig.locked.transform.type = "valueMap"
schedule.operationTooltipConfig.locked.transform.values.true = "Да"
schedule.operationTooltipConfig.locked.transform.values.false = "Нет"

Matching rules

• Mapping keys are matched by the string form of the source value.
• Boolean values therefore use keys true and false.
• Date values are matched by their ISO 8601 string form.
• If no mapping entry matches, the transform returns fallback when it is provided.

Important limitations

• Strings such as (value) => value ? 'Да' : 'Нет' are treated as plain data and are not executed.
• Unsupported transform descriptor types are ignored.
• Date formatting is still handled separately by the panel date-display layer.

Demo fixture

The local fixture application local-gantt-transform-demo demonstrates this behavior for operation hover tooltips.
