Deleting a layer with modifications

[mihau]

When deleting a layer containing modifications a warning message should be displayed - e.g. similar as the one when exiting the application (Unsaved changes/There are unsaved changes. Discard the changes and continue? Yes/No)

• create a new layer
• create some elements (e.g. nodes)
• delete the layer => layer get's deleted without warning message

It happened to me twice by pressing delete button instead of hide.

There is usually a confirmation dialog, it can be set to auto-hide by the user.

The current confirmation appears whether or not the layer contains changes, and says nothing about the layer containing unsaved changes, or losing work if the changes are not uploaded.

This is different from the original request, which was to warn the user if the layer to be deleted contains changes, and that the changes will be lost if they do not upload them.

I do not think it is necessary to ask for confirmation when a layer that does not contain changes is deleted: if one accidentally deletes a layer that has no changes, no work has been lost—it can simply be downloaded again.

However, the confirmation is important if the layer contains changes, as work can be lost if a layer that contains changes is deleted before uploading.

I had the same problem. The attached patch now shows a confirmation dialog in case of changes. It's just like the dialog you get when you close the application, only I left out the "Some changes came from uploading new data to the server" part, as it's not clear to me what exactly that means.

Fixed in r745.
