How to react to light/dark mode changes in macos?

[lasmr]

Hi,

I have an app with highly customized UI and I need to know what mode is used in macos when the app starts and I need to listen to changes in the mode.

But I can't find the rith Qt API to deal with this.

Thanks.

Hi,

Because, AFAIK, there's currently nothing specific for that available. You should check the macOS API to see if there's an event or equivalent that you can catch.

Have you found a solution?

I think the only thing you can rely on is QPalette colors.

for example the window background color:
palette().color(QPalette::Window);
returns:
QColor(ARGB 1, 0.196078, 0.196078, 0.196078) for dark mode
QColor(ARGB 1, 0.92549, 0.92549, 0.92549) for light mode
