Hi,
this is about the 'text' property and possibilities to determine the text label string.
At the moment, the only option is to specify a certain key and the renderer
will look up the corresponding tag value and display it (if found). This is
somewhat limited, it would be nice to show a localized name if present and fall
back to the generic or English name otherwise. Or display the name of a
building, and if no name is given, show the house number. This would be written
like 'text-source: auto;' or 'text-method: building;'. On top of that, is
should be possible to provide a static string as label or use an eval
expression to determine the text value.
Compared to a simple property such as 'width: 5;', the 'text' property works in
a more complicated manner as it explicitly refers to the object tags. So it
might be appropriate to change the name to something more complicated, like
'text-from-tag'. It is less memorable, but more clear in meaning.
Any suggestions how all this could be represented?
Sebastian
