物业＆＃39; imageUrl＆＃39;对象ApplicationWindow_QMLTYPE_39_QML_108（0x1934a60）不是函数

Question

我正在尝试使用下面列出的QML代码中的imageUrl函数，但是我收到以下错误：Property 'imageUrl' of object ApplicationWindow_QMLTYPE_39_QML_108(0x1934a60) is not a function。

这是我的QML代码（请注意评论）：

ApplicationWindow {

    id:window
    visible: true
    width: 640
    height: 480
    title: qsTr("Open Picture")

    menuBar: MenuBar {
        Menu {
            title: qsTr("File")
            MenuItem {
                text: qsTr("&Open")
                onTriggered: fileDialoge.open()
            }
            MenuItem {
                text: qsTr("Exit")
                onTriggered: Qt.quit();
            }
        }
    }

    //this is my function
    function imageUrl(text)
    {
        console.log("Url: " + text);
    }

    // the user browse image from here
    FileDialog {
        id: fileDialoge
        nameFilters: [ "Image files (*.png *.jpg)", "All files (*)" ]
        selectedNameFilter: "Image files (*.png *.jpg)"
        selectMultiple: true
    }
    Button {
        text: "Open"
        anchors.verticalCenter: parent.verticalCenter
        onClicked: fileDialoge.open()
    }

    // and I want the function to be called here
    Button {
        x: 136
        text: "Send"
        anchors.verticalCenterOffset: 0
        anchors.verticalCenter: parent.verticalCenter
        onClicked: window.imageUrl(FileDialog.fileUrl)
    }
}
