# Edit HMI Components

After [adding components](/hmi-designer/design-steps/add-hmi-components.md) to the panel you can edit them to change their appearance and determine how they will interact with the robot program.

Select the component that you want to edit and use the side toolwindow to change its properties.

Inside the side toolwindow you will find two different gropus of properties: **UI properties** and **Program Properties**.

**UI Properties** are used to configure the components graphical look, i.e colors, size, formatting, alignment, icons.

**Program Properties** instead are used to configure how the graphical element will interact with the robot program. This is achieved linking the component with variables or functions defined inside the robot program. I.e. you can link a button with a function, in this way each time the button is cliked the choosen function will be executed.

{% tabs %}
{% tab title="Universal Robots" %}

{% hint style="info" %}
You can develop the robot functions both with **Polyscope** or with **Scripting** as you prefer, just remeber to use the same function name to link it with the HMI component.
{% endhint %}
{% endtab %}

{% tab title="Doosan Robotics" %}

<figure><img src="/files/Eu6yAduAieBKIeV0GPKT" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
You can develop the robot functions both with **Task Editor** or with **Scripting** as you prefer, just remeber to use the same function name to link it with the HMI component.
{% endhint %}
{% endtab %}
{% endtabs %}

Each HMI components has is own characteristic properties that determines how it looks and how it will interact with the robot program. Have a look a the [HMI components list](/hmi-designer/hmi-components.md) to check properties of each element.
