Review request for KDevelop.


Repository: kdev-qmljs


Description
-------

When the declaration corresponding to a name is being looked for, and the name is "onXXX", declarations named "XXX" are also returned if they are signals. This allows UseBuilder to register "onClicked" as being an use of the "clicked" signal.

This patch is very general and modifies directly getDeclaration(). This has the advantage that the search logic can be used everywhere (for instance, DeclarationBuilder will soon be able to expose the parameters of a signal to its slot), but getDeclarations() must be very careful not to return an unexpected declaration. For instance, if the user, in a Javascript file, declares an "line" variable, "online" must not be an use of "line". This is done by ensuring that the returned declaration, when "on" has been stripped, is a QML signal.

Testing
-------

Two unit tests have been added: one ensures that "onDataChanged" is an use of "dataChanged", and one ensures that "online" is not an use of "line" in Javascript.


Thanks,
