Altering the Color of GUI Elements in Fyne

Within the realm of the Fyne library, it is possible to encounter a query regarding the customization of GUI component colors. While Fyne offers a theming mechanism for the application as a whole, it lacks native support for altering the color of individual elements.

Proposed Solution: Individual Styling

This issue has been discussed in fyne-io/fyne issue 255, where the suggestion of assigning individual styles to widgets was put forth. However, this proposal was not implemented.

Rationale

As stated by fyne-io/fyne's maintainer Andy Williams, the design philosophy of Fyne emphasizes consistency in the user experience. Therefore, the library prioritizes a predetermined style for its widgets, which can be modified through theming.

Alternative Approach

Despite the absence of direct color customization, Fyne provides alternate methods to achieve variations in appearance.

• Custom Widgets: Developers can create custom widgets that inherit specific colors based on their implementation.
• Semantic Styles: Fyne assigns semantic styles to certain widgets, such as "primary" for buttons. These styles utilize the highlight color defined in the theme.
