[Qt-creator] How to match function invocation and definition?

You don't need the declaration as a string. Since you did a look up, the 
resulting symbols represent the possible declarations. E.g. check your 
"d" symbol (d->fileName(), d->line(), d->column(), d->type()).

If you need the matching definition for your declaration (recommended, 
see below), use SymbolFinder::findMatchingDefinition().

ModelItemInfo has fileName, line and column members. You could compare 
these to the fileName, line and column of the symbol/function returned 
by SymbolFinder::findMatchingDefinition().

Note that the locator data provides only information about definitions, 
e.g. function definitions, not their declarations. So if you have a 
symbol you want to match with the function from the locator data, make 
sure its origin is a function definition.

No since LocatorData does not provide these kind of types.
