Invalid property name "title"

[dalishi]

Hi im trying the qt tutorial but got this invalid property name "title" error. Although the program is successfully compiled and running OK. Should I worry about this warning? im using Qt5.15 on Ubuntu20.

Hi,

QML is not a compiled language like C++ (this has changed a bit, see this article about the Qt Quick compiler old and new) hence the absence of compilation error.

As for the warning you are getting, it is correct the ApplicationWindow type does not have a title property directly but it has through inheritance from Window. So it's likely a glitch from the code model.

ApplicationWindow has title. Simply ignore the warning in qt creator.

@SGaist @JoeCFD thanks for the explanation.

So, the solution is ?....
I have many instance of this problem.
For example, try to import StateMachine as DSM just like document done. Many wrong error about random properties of State and DSM.State will be emitted every where!
