How can I force the window to keep fullscreen?

[Mr-Milk]

If I don't want my user to exit fullscreen by pressing keyboard ESC or F11 and by switching between desktop. Is there any way I could achieve this in tauri?

hello, I think I accidentally found (part of) the answer, though I am pretty unsure. I am creating a windows screensaver app, and screensavers on windows are essentially executables running fullscreen with .scr extension. I only have only have "fullscreen": true and "title" property under tauri.conf.json > tauri > windows[]. The result of this is that I can't use either f11 or esc to exit fullscreen. Do note that I only have windows machine tested currently. If you are on other platforms, you can try it out yourself to verify my claim.

It works on linux too.

Thank you, on macOS, it does open in fullscreen mode but it leaves when pressing esc.
The only workaround I found so far is by adding a global event listener:

    const onKeyDown = (event: KeyboardEvent) => {
      if (event.key !== "Escape") {
        return;
      }

      event.preventDefault();
    };

    window.addEventListener("keydown", onKeyDown);

I am all ears for a more elegant solution though.

Hi,
In js you can do that :

import { appWindow } from "@tauri-apps/api/window";
await appWindow.setFullscreen(true);

In tauri.conf.json :

    "tauri": {
        "allowlist": {
            "window": {
                "setFullscreen": true
            }
        },

Thanks brother, appreciate it.

With Tauri v2:

JavaScript

import { getCurrentWindow } from '@tauri-apps/api/window';
await getCurrentWindow().setFullscreen(true);

capabilities.json

"permissions": [
  "core:window:allow-set-fullscreen"
]
