Prompt to confirm saving when file already exists

[merilec]

When selecting a location and file name to save a file to (via saveFile), a file with that file name might already exist. The picker should then prompt the user to confirm saving and replace it, similar to how it is done in many other programs.

Is there any version of this feature planned to be implemented?

@bhlin790, sorry for keeping you waiting so long. Contributing to open-source has been a low priority for me for the last 12 months.
The Linux implementation is ready. Now, I'm working on the macOS and Windows implementation.

I just realized that macOS and Kubuntu (+ other Linux distributions that come with the CLI tool kdialog) always prompt the user to confirm overwriting an existing file.

Only on other Linux distributions that ship with the CLI tool zenity (e.g. Ubuntu) and on Windows, it is possible to enable/disable this additional prompt dialog when the user chooses an already existing file.

Initially, I planned to add a new parameter confirmOverwrite to FilePicker.saveFile() to enable/disable this behavior. Now that I know that we cannot control the behavior on macOS nor on Kubuntu, we could also decide to enable the confirm dialog on all platforms. Most probably it is still best to let users of our library decide which behavior they want? Even though it cannot be disabled on macOS and Kubuntu?

@miguelpruivo , @bhlin790 what would be your preferred approach?

Update: I made the decision to adapt only the Windows implementation so that it behaves identical to the macOS and Linux implementation. As we cannot enable / disable the confirmation prompt on macOS nor on some Linux distributions, it doesn't make sense to make this behavior configurable. Instead, I think it's best to make all platforms show this confirmation dialog.

Will be implemented with v5.2.7. Now, we're waiting for approval from Miguel 😉
