    Problem with DocumentGalleryModel filters??

    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 :
    Code:
        GridView {
            id: grid
    
            model: DocumentGalleryModel {
                //autoUpdate: true
                rootType: DocumentGallery.Image            
                properties: [ "url" ]
    
                filter: GalleryWildcardFilter {
                    property: "fileName"
                    value: "*.jpg"
                }
    
            }
    
            delegate: imageDelegate
        }

    GalleryEndsWithFilter :
    Code:
        GridView {
            id: grid
    
            model: DocumentGalleryModel {
                rootType: DocumentGallery.Image            
                properties: [ "url" ]
    
                filter:  GalleryEndsWithFilter {
                    property: "fileName"
                    value: ".jpg"
                }
    
            }
    
            delegate: imageDelegate
        }

    Re: Problem with DocumentGalleryModel filters??

    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
    }
    }
    }

    Re: Problem with DocumentGalleryModel filters??

    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:

    Code:
    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 ...
