Review request for KDevelop.


Repository: kdev-qmljs


Description
-------

This patch adds a special-case for "parent" in ExpressionVisitor. Even if every QML object has a "parent" property of type QQuickItem, the user most of the time wants to refer to the enclosing QML component when he/she types "parent". If there is no enclosing QML component (the current component is a top-level one or something else happened), then ExpressionVisitor falls back to the old behavior and returns a QQuickItem instance.

I would like to be able to activate this special handling of "parent" only for QML files, because Javascript files may use "parent" for something else. Is it possible, given a DUContext, to find its language? (or is there a way for the QML/JS plugin to store in the DUContext that the file is a Javascript one or a QML one?)

Testing
-------

A new unit test has been added. "parent" is used to refer to the enclosing component of a sub-component, and uses are correctly built. The rest of the unit tests pass. Manual testing shows that the highlighting of "parent" and the code-completion for "parent." is as expected.


Thanks,

Denis Steckelmacher
