[Patch needs rework] User should be warned when UnGlue-ing two ways outside the download area

[anonymous]

If I attempt to delete a node on a way outside my download area, the program will warn me that I am doing something without all the facts. The warning dialog correctly warns me that I am operating on nodes that may belong to ways I can't see.

However, if I have two ways that cross outside my download area, I can UnGlue the two ways without a warning, even though it is possible that a third (unseen) way may also use the same node. I haven't tested it, but I presume that when the change set is uploaded, any unseen third way will remain attached to one of the duplicates, but not the other. This is bad, because the user will not be able to take any unseen ways into account when performing operations on the duplicates.

I suggest that when a user attempts to UnGlue two ways outside the download area, the program should present a warning dialog similar to the one that pops up when the user attempts to delete a node outside the download area.

Thanks!

Patch attached. I'm not sure whether I got the translation stuff correct.

No, i18n wont work this way. Never calculate or modify texts. Better is to make it generic (use e.g. "change" or "modify") and f.e. pass the complete title text as argument.

It should suffice to change …

Command.checkAndConfirmOutlyingOperation("unglue", getEditLayer(), p); 

… into …

Command.checkAndConfirmOutlyingOperation(marktr("unglue"), getEditLayer(), p); 

… in order to get I18n correct, right?

No. Don't assume foreign languages have the same structure as German or English. It is always hard to translate texts, when other text is inserted into it. This cannot always be prevent (sometimes you must construct strings) but should not be generalized. Better is always to pass complete strings whenever possible.

An example:

if(type == "way")
  text = tr("The object nr. {0} is a way.", id)
else if(type == "node")
  text = tr("The object nr. {0} is a node.", id)
else if(type == "relation")
  text = tr("The object nr. {0} is a relation.", id)

is much better than

  text = tr("The object nr. {0} is a {1}.", id, tr(type))

Look at one of the slavic languages and you see why :-)
