Using a supported version?

• [X] I have searched searched open and closed issues for duplicates.

Overall summary

When receiving a file, iE a pdf. - Clicking on it will open the "Save" dialog, but neither file extension, nor filename are carried over. - I have to type the name myself.

Steps to reproduce

1. Go to any chat
2. Try to open a received file
3. look at the "Save" dialog

Expected result

The filename should be carried over to the "Save" dialog

Actual result

The filename is not being carried over.

This is likely an issue in the framework we use Electron. I'm not able to reproduce the issue likely because of OS differences. But if you wanted to report it back to Electron, the first step would be to see if you can reproduce it more minimally.

You can download the Electron Fiddle app and load this fiddle I've started for you: https://gist.github.com/beb77598fa7c7f3ad843fa32b359fa73. If you click "Run" you can see how the app behaves on your operating system.

I'm going to close this since I can't reproduce it

FYI I can repro this on Kubuntu 24.04. @jamiebuilds-signal, what distro are you using?

If I understand this correctly, your posted fiddle opens a dialog to select a file. - But how is this the same as if I would want to save a file, and want the dialog to receive that filename, which was given in the message from signal-chat?

What would I report to electron project, can you point me into the correct direction here, maybe?

I have fiddled a bit with what you have provided and I come up to the conclusion, it should be something along these lines, or am I off charts here??

async function main() {
  // Wait until the app is ready
  await app.whenReady()

  **const options = {
    defaultPath: app.getPath('documents') + '/electron-tutorial-app.pdf',
  }

  // Show a dialog to select a file
  const opened = await dialog.showSaveDialog(null, options, (path) => {console.log(Path);})**

  // Stop the dialog was closed without selecting a file
  if (opened.canceled) return

  // Get the selected file path
  const [filePath] = opened.filePaths

  // Get the selected file name ("/path/to/file.txt" -> "file.txt")
  const fileName = path.basename(filePath)

  // Show a dialog to save 
  await dialog.showSaveDialog({ defaultPath: fileName })

  // Goodbye
  app.quit()
}

@dominikegert Sorry yes it seems like you could simplify the code even more then:

const { app, BrowserWindow, dialog } = require('electron')

async function main() {
  // Wait until the app is ready
  await app.whenReady()

  // Create a new window
  const window = new BrowserWindow()

  // Show a dialog to save a file
  await dialog.showSaveDialog(window, { defaultPath: 'example.pdf' })

  // Goodbye
  app.quit()
}

main()

This is a screenshot from macOS (Not at my other computer for the moment):

When you open this updated fiddle are you not seeing "example.pdf" in the default file name?

Actually I am not...
