Processus : Main

Événements

Le module nativeTheme déclenche les événements suivants :

Événement 'updated'

Émis lorsque quelque chose dans le NativeTheme sous-jacent a changé. This normally means that either the value of shouldUseDarkColors, shouldUseHighContrastColors or shouldUseInvertedColorScheme has changed. You will have to check them to determine which one has changed.

Propriétés

Le module nativeTheme dispose des propriétés suivantes :

nativeTheme.shouldUseDarkColors Lecture seule

A boolean for if the OS / Chromium currently has a dark mode enabled or is being instructed to show a dark-style UI. If you want to modify this value you should use themeSource below.

nativeTheme.themeSource

Une propriété string qui peut être system, light ou dark. It is used to override and supersede the value that Chromium has chosen to use internally.

Setting this property to system will remove the override and everything will be reset to the OS default. By default themeSource is system.

Settings this property to dark will have the following effects:

  • nativeTheme.shouldUseDarkColors will be true when accessed
  • Any UI Electron renders on Linux and Windows including context menus, devtools, etc. will use the dark UI.
  • Any UI the OS renders on macOS including menus, window frames, etc. will use the dark UI.
  • The prefers-color-scheme CSS query will match dark mode.
  • The updated event will be emitted

Settings this property to light will have the following effects:

  • nativeTheme.shouldUseDarkColors will be false when accessed
  • Any UI Electron renders on Linux and Windows including context menus, devtools, etc. will use the light UI.
  • Any UI the OS renders on macOS including menus, window frames, etc. will use the light UI.
  • The prefers-color-scheme CSS query will match light mode.
  • The updated event will be emitted

L'utilisation de cette propriété devrait s'accorder avec le "mode sombre" classique du système dans votre application où l'utilisateur a trois options.

  • Suivant OS --> themeSource = 'system'
  • Mode sombre --> themeSource = 'dark'
  • Mode clair --> themeSource = 'light'

Votre application devrait alors toujours utiliser shouldUseDarkColors pour déterminer quel CSS appliquer.

nativeTheme.shouldUseHighContrastColors macOS Windows Lecture seule

A boolean for if the OS / Chromium currently has high-contrast mode enabled or is being instructed to show a high-contrast UI.

nativeTheme.shouldUseInvertedColorScheme macOS Windows Lecture seule

A boolean for if the OS / Chromium currently has an inverted color scheme or is being instructed to use an inverted color scheme.

nativeTheme.inForcedColorsMode Windows Readonly

A boolean indicating whether Chromium is in forced colors mode, controlled by system accessibility settings. Currently, Windows high contrast is the only system setting that triggers forced colors mode.
