How to set Electron file dialog to modal?

[zole40]

Hello. I want to open the file dialogue on the same screen as the application. Now it always opens on the main screen.
I found an issue and PR that made it possible, but the modal property is undefined by default, and I did not find a preference, a flag or any other way to set it to true.
Can I change it, or do I have to implement my ElectronFileDialogService?

In the meantime I made a workaround to fix it in our app, but I think there must be a better way.

Hi @zole40

There's currently no way to set the modal option via a preference. The expectation is that the callers of the FileDialogService pass the modal prop in the arguments, for example:

this.fileDialogService.showOpenDialog({ title: 'My Open Dialog', canSelectFiles: false, modal: true }, folder)

If you want all open and save dialogs created by the service to always be modal, then your workaround is the way to go.

Hope this helps!

I just double checked my own code, it's been a while since I wrote it.

The initial intention was that if the modal prop is undefined, it it still being evaluated as true. So all dialogs should have been modal by default.
This seems to no longer be the case and it's likely a regression. Could you open an issue for this, please?
