Theme Editor

The Theme Editor lets you set the visual appearance and color scheme of each App individually, so every App matches your corporate branding or specific design requirements.

How to apply a theme

To set your App's theme:

1

Open Theme Editor

From the App Builder's Top Bar, open the Theme Editor ().

2

Choose a base theme

Select from Generic, Material, or Fluent to define the overall style of your widgets.

3

Select a color scheme

Choose a predefined scheme from the left menu or manually adjust individual colors to create a custom look.

4

Apply changes

Click Apply to refresh the UI preview with your new theme.

5

Exit

Click the App Editing icon () in the Top Bar to return.

Heisenware's theming engine is built on the DevExtreme framework. For advanced details on the base themes, see the official DevExtreme documentation.

How theming affects widgets

Most widgets carry color settings that respond directly to the App's theme. By default, a widget's color is Automatic.

• Automatic: The widget inherits its colors from the global App theme. If you change the theme later, the widget updates automatically.

• Manual override: If you set a specific color for a widget (for example, making a specific button solid red), that setting overrides the theme. This specific color remains fixed even if the global theme changes.
