Problem with DocumentGalleryModel filters??

[robert26]

Hi!

I want to display jpg images in a gallery using a DocumentGalleryModel. If I dont use a filter it works just fine (but of course all image types are displayed in that case), but as soon as I apply a filter to the DocumentGalleryModel I get the following error: "QML DocumentGalleryModel: The value of filter is unsupported". I tried differrent filters: GalleryWildcardFilter, GalleryEndsWithFilter, but to no avail.

Hardware used: C7
SDK used: Qt SDK 1.1
Qt Creator 2.1.0
Qt version: 4.7.3
QT Mobility: 1.1.3

Any idea why I get the error all the time?

GalleryWildcardFilter :

    GridView {
        id: grid

        model: DocumentGalleryModel {
            //autoUpdate: true
            rootType: DocumentGallery.Image            
            properties: [ "url" ]

            filter: GalleryWildcardFilter {
                property: "fileName"
                value: "*.jpg"
            }

        }

        delegate: imageDelegate
    }

GalleryEndsWithFilter :

    GridView {
        id: grid

        model: DocumentGalleryModel {
            rootType: DocumentGallery.Image            
            properties: [ "url" ]

            filter:  GalleryEndsWithFilter {
                property: "fileName"
                value: ".jpg"
            }

        }

        delegate: imageDelegate
    }

I tried the following code in simulator/linux and it works fine for me.

import Qt 4.7
import QtMobility.gallery 1.1

Rectangle {
width: 1024
height: 768

GridView {
anchors.fill: parent
cellWidth: 128
cellHeight: 128

model: DocumentGalleryModel {
rootType: DocumentGallery.Image
properties: [ "url" ]
filter: GalleryWildcardFilter {
property: "fileName";
value: "*.jpg";
}
}

delegate: Image {
source: url
width: 128
height: 128
}
}
}

Hi gnuton,

can verify that your code snippet works on simulator/Windows, but it doesnt work on hardware. Same error message when testing with my Nokia C7:

Executable file: 10251 2011-06-14T10:30:29 C:\QtSDK11RC\Symbian\SDKs\Symbian3Qt473\epoc32\release\armv5\udeb\QtQuickTestApp.exe
Starting application...
Application running with pid 9890.
[Qt Message] file:///C:/Private/e13e4628/qml/QtQuickTestApp/main.qml:13:8: QML DocumentGalleryModel: The value of filter is unsupported

(main.qml contains nothing but your snippet)

Will also check the Qt bug-tracker for problems ...

There is some similar Bug reported for which poster has already commented. If required anyone interested can track it.

Yup, I commented on QtMobility-1656 and I am tracking it also. Keep you updated on the progress there (if there is any) ...
