Not able to add a list property to QML element

jess0pher

This seems like valid QML to me

@Rectangle {
width: 360
height: 360

Image {
    id: charsprite
    property list<string> frames: ["qrc:/chrsprite/walk1.png","qrc:/chrsprite/walk2.png"]
    property int frame: 1
    height: 200
    width: 100
    source: frames[frame]
}
Timer {
    interval: 500
    running: true
    repeat: true
    onTriggered: charsprite.frame = charsprite.frame+1 % 2
}

}@

But whenever I run the code, the QML parser gives the following error:
@...qml/MiniGame/main.qml:10:40: Expected a qualified name id
property list<string> frames: ["qrc:/chrsprite/walk1.png","qrc:/chrsprite/walk2.png"] @

What am I doing wrong here in my declaration/initialization of the charsprite.frames property?

jess0pher

and position 10:40 is "qrc:/charsprite/walk1.png", fyi

Well it would be nice to have the type safety, but one can use variant instead of list<string>, so I'm just going with that for now.

HI,

From memory currently only lists of object types (and not basic types like strings) are supported using the property list<type> syntax. You might want to check http://bugreports.qt.nokia.com to see if there is an existing suggestion for this, or add one if there isn't.

Regards,
Michael

Yup, thats it. I guess the documentation does sneak that in (the word object is used, but its not specific about what sort of object). So the only thing i can see actually erroneous about the behavior is how and where the parser reports it. It should be reporting it in the LHS, since the type itself is malformed. Thanks Michael.

i know long time ago. but for the next
try that.

property variant frames: ["qrc:/chrsprite/walk1.png","qrc:/chrsprite/walk2.png"]

i tested it with int and it works fine.
