Duplicated Property Name

Multiple properties in the same QML component scope have the same name.

Components with duplicate property names will not be created at runtime: they will be null instead.

 import QtQuick

 Item {
     property int helloWorld
     property int helloWorld
 }

To fix this warning, remove the duplicate property or rename it:

 import QtQuick

 Item {
     property int helloWorld
 }

Multiple signals in the same QML component scope have the same name.

Components with duplicate signal names will not be created at runtime: they will be null instead.

 import QtQuick

 Rectangle {
     signal helloWorld
     signal helloWorld
 }

To fix this warning, remove the duplicate signal or rename it:

 import QtQuick

 Rectangle {
     signal helloWorld
 }
