Support for iPadOS Windowed Apps

[mydesweb]

As you probably know on iPadOS (26) the user if freely to resize the app window (either width or height) realtime, so my question is: how to handle this with Unistyles / React Native?

Currently, if I resize my app window to the minimum everything becomes extremely small.

Have you tried to listen to rt.screen.width and rt.screen.height in your StyleSheets?

@jpudysz Sure — I believe that when you resize the window, it behaves differently; it uses logical pixels instead of physical ones. That’s why the row separators, which use StyleSheet.hairlineWidth for their height, become invisible.

It’s more complex than it seems: on a mobile screen with the same dimensions as the resized iPad window, the interface looks fine — and it also looks fine in full-screen mode on the iPad.

You can try with:

I will try.. also do you know how to control how much the app window can be resized? I belive we should be able to set a minimum size.. and below that size the resize should not be posssible.

@jpudysz nativeBreakpointsMode doesn't solve the problem, basically points = pixels / pixelRatio , we should always use points for simplicity..

[jpudysz]

I have no idea, if the values from rt are correct that's all I can do. Maybe issue lies deeper in RN.

@jpudysz somehow on iPad (only) we should increase the size of every element proportionally with the reduced window size.. seems too complex to handle this, I will disable the feature, but if you want to try it on iPadOS 26 -> Settings -> Multitasking & Gestures -> enable Windowed Apps
