I do a qualified import for felgo (import Felgo 3.0 as FelgoModule) as a solution to namespace problems I had.

Now I call a method of FileUtils as: fileName = FelgoModule.FileUtils.storageLocation(FelgoModule.FileUtils.DocumentsLocation, nameString)

this results in a runtime error: TypeError: Property ‘storageLocation’ of object [object Object] is not a function

How to call this function with a qualified import.??

Hi,

you can see examples in the documentation at e.g: https://felgo.com/doc/apps-howto-access-and-store-files/

The FileUtils are available with the context property fileUtils (lowercase!) just like nativeUtils. For accessing the enums, you can still use the FileUtils type with uppercase.

Best,
Alex

Hi Alex,

 

I have read the documentation but the examples do not import Felgo 3.0 in a separate namespace but do the Felgo import as last to prevent namespace errors, something advised by you in several posts. I prefer to import the module in a new namespace as I wrote in the post. Like I said I than get the error storageLocation is not seen as a function of FileUtils, irrespective of using a capital F or not.

So the question is how to call that function in the qualified namespace?

I prepared an example following my explanation above:

import Felgo 3.0 as FelgoModule
import QtQuick 2.0
      
FelgoModule.App {
  FelgoModule.NavigationStack {
    FelgoModule.Page {
      title: "Qualified Import"
      
      FelgoModule.AppText {
        text: fileUtils.storageLocation(FelgoModule.FileUtils.DownloadLocation, "_packages/myPackage/myImage.png")
      }
    }
  }
}

fileUtils is an instance of type FileUtils, available as context property from anywhere. You can read more on the concept of context properties and how to use them yourself here: https://felgo.com/cross-platform-development/how-to-expose-a-qt-cpp-class-with-signals-and-slots-to-qml

Cheers,
Alex

Ok, thanks Alex.

I understand that the function call does not need the namespace but the enum does

Made the change and it works.
