ThemePanelWidget(Func<Hex1bTheme, Hex1bTheme>, Hex1bWidget)

A widget that applies theme customizations to its child widget tree. Use this to override theme elements (colors, characters, etc.) for a specific portion of your UI without affecting the rest of the application.

Parameters:

• ThemeMutator (Func<Hex1bTheme, Hex1bTheme>): A function that receives a clone of the current theme and returns a (possibly modified) theme. The returned theme is used for rendering the child subtree. The theme is already cloned, so you can safely call Set() directly.
• Child (Hex1bWidget): The child widget to render with the customized theme.

public ThemePanelWidget(Func<Hex1bTheme, Hex1bTheme> ThemeMutator, Hex1bWidget Child)

ThemeMutator

A function that receives a clone of the current theme and returns a (possibly modified) theme. The returned theme is used for rendering the child subtree. The theme is already cloned, so you can safely call Set() directly.
