Image::mipmap is an 'invalid property'

Robbert

I've just upgraded from Qt 5.2 to 5.3 with the latest and greatest Qt Creator 3.1.1. I want to try out the new mipmap property added to the QML Image type (see "Image::mipmap":http://qt-project.org/doc/qt-5/qml-qtquick-image.html#mipmap-prop), but Qt Creator marks the property as an 'invalid property name' in the QML editor and the application crashes if I try to run it.

Before upgrading, I uninstalled Qt 5.2 and removed C:\Qt entirely. In Projects > Build & Run, it says I'm building against Desktop Qt 5.3.0 MinGW 32bit. So there's no way it's still building against 5.2, is there?

What am I doing wrong?

@Image {
source: "image.png"

width: 10
height: 10

mipmap: true // Causes crash.

}@

I've reported this as a bug since I'm pretty sure I'm running Qt 5.3: "QTBUG-39302":https://bugreports.qt-project.org/browse/QTBUG-39302

Hi and welcome to devnet,

You should also post a minimal compilable example that shows the behavior. This way it ensures that the developer and you are testing using the same pieces of code with the same data.

Thanks for your help SGaist.

I found the problem - apparently the mipmap property was added to QtQuick 2.3 so a wrong import statement caused the problem.

This works:

@import QtQuick 2.3
Image {mipmap: true}@

I've closed the bug report in JIRA.

The "Image page":http://qt-project.org/doc/qt-5/qml-qtquick-image.html says Import Statement: QtQuick 2.2, which is what misled me. Can you update the page accordingly?

It's still a bug, but a documentation bug, a fix is on its way

Thanks SGaist! Wish I could help out with the docs, but I guess I'll have to spam the forums some more first.

Well, you can help, no problem with that :)
