Question

我的项目中有奇怪的qml错误，

Warning: QQml_colorProvider: no color provider has been set! 
"qrc:/gui/FirstPage.qml:5 Type GuiPage unavailable
qrc:/gui/GuiPage.qml:4 Invalid property assignment: color expected

这是我的GuiPage.qml：

import QtQuick 2.1

Rectangle {
    color:"transparent"
    implicitWidth: 380
    implicitHeight:  350
    property string pageName: "sample"
    property bool active : false
    readonly  property int firstPage: 1
    readonly  property int lastPage: 2
    readonly property int normalPage : 3
    property int pageType : firstPage
    signal pageActivate
    signal pageClose

    property bool hasBlockers: false

    property int pageId: 0
    property QtObject fontLoader:  FontLoader{
        source: "font/Cuprum-Regular.ttf"
    }
}

我使用git stable branch的最后一个Qt，静态构建。

为了避免这个问题，需要在Qt5上放一个小补丁（Qt 5.1.1版本仍需要）
