Force window to be in the foreground

[woelper]

Sorry for this potentially stupid issue but I have a very obscure use case where I trigger this very nice library from an electron app that communicates with a rust backend via rest/rocket. However the native file browser always opens in the background, making it hard or impossible to see. Is there a way to bring it to focus automatically?

Numerous commits are in the upstream nativefiledialog project devel branch as of today that have improved focus issues on MacOS and X/Linux/GTK targets.

It's still possible to get the file picker in the background. This is serious for full-screen games with a modal dialog. The user is stuck with a dead keyboard and mouse. CTL-ALT-DEL, or, if the window has a title bar, minimizing it, will expose the file picker, but that's about it.

Look in the "development" menu for an open file menu option.
