File picker

This page is all about letting a user choose files from their file system. NovaOS lets users select files from the registered Files@runnova app.

Requesting a file selector window

Here is the method to summon a choose file window with the default files app in NovaOS.

await ntx.olp.useHandler("file_manager", { 
 "opener": "any", 
 "dir": "Downloads/" 
});

This returns the selected file ID once the user has selected it.

Here, we use the OL protocol to launch the application with the data, which has some parameters.

Apps can access this feature through the myWindow method. To use the myWindow method, you have to use the greenflag() function. Otherwise, it will return undefined. This is due to the fact that the myWindow object is only defined after the app document is loaded.
