Description
Consider the following example:
import QtQuick 2.4 import QtQuick.Window 2.2 Window { visible: true Rectangle { anchors.fill: parent property alias mouseArea: mouseArea width: 360 height: 360 MouseArea { id: mouseArea anchors.fill: parent onClicked: { var b = { "employees":[ {"firstName":"John", "lastName":"Doe"}, {"firstName":"Anna", "lastName":"Smith"}, {"firstName":"Peter", "lastName":"Jones"} ] } var x = {a: 12, b: [1,2,3]}; Qt.quit(); } } } }
In QtCreator set a breakpoint at "Qt.quit()" and trigger the code clicking somewhere. With Qt 5.4 you get the correct values for the local variables x and b in the "Loxals and Expressions" view. With Qt 5.5 you get data from some mouse event:
Locals this object x object accepted true boolean button 1 number buttons 0 number isClick true boolean modifiers 0 number objectName string objectNameChanged object wasHeld false boolean x 54 number y 54 number Inspector Window object Window Expressions returned value Tooltip
