| -------------------------------- | --------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **hmi\_set\_enabled**(id, value) | Set enable status of UI component. This function can be used to enable or disable a HMI component while robot program is running. | **id** - String, Id of UI component. Identifier of UI component whose enable status you want to change. In the HMI editor, right-click on component and select Copy Id to get its string identifier. **value** - Bool, Enable status value to set for UI component. False will disable the component, True will enabled it. |
| **hmi\_set\_visible**(id, value) | Set visibility of UI component. This function can be used to hide or show a HMI component while robot program is running.         | **id** - String, Id of UI component. Identifier of UI component whose visibility you want to change. In the HMI editor, right-click on component and select Copy Id to get its string identifier. **value** - Bool, Visibility value to set for UI component. False will hide the component, True will display it.          |
