Hi,
See https://josm.openstreetmap.de/ticket/12075.
The idea is to ask for confirmation if a GeoImageLayer with modified
image properties is deleted. What is the best/right way to do that?
The AbstractModifiableLayer seems to serve that purpose. GeoImageLayer
could extend AbstractModifiableLayer instead of Layer. But there is not
a single file associated with the layer but one file per modified image.
There is not really a "recommended action" for the SaveLayersDialog.
The AbstractModifiableLayer would need to be extended to have something
like isAbleToUploadToServer() and isAbleToSaveToFile() to disable the
according check-boxes of the SaveLayersDialog. The logic in
Main.saveUnsavedModifications() would need to be changed to consider the
layer if neither requiresSaveToFile() nor requiresUploadToServer()
returns true. Would it make sense to add something like
requiresSomeAction() to AbstractModifiableLayer and
Main.saveUnsavedModifications()? The "action" could be a string that is
displayed in the SaveLayersDialog.
Thanks,
Holger
