我在为Harmattan部署使用Qt 4.7.4/QtQuick 1.0编写的应用程序时遇到问题。 当模拟器中的所有内容都正确时，应用程序在诺基亚N9（MeeGo 1.2 Harmattan，版本PR1.1）上部署时不会绘制任何用户界面。部署成功，应用程序可以在设备上的应用程序列表中找到，甚至可以在QtCreator中看到控制台日志输出，但是没有迹象表明应用程序实际在设备上运行 - 我可以自由浏览系统并打开其他应用程序，而QtCreator说我的应用程序正在运行。Qt应用程序不会在MeeGo上在诺基亚N9上绘制任何用户界面
在QtCreator应用输出图说：

而且继承人的编译输出：

虽然编译输出可能会提供有关该错误的一些提示，我不知道是什么出错了。可笑的是，在一些早期的开发阶段，应用程序在设备上工作。但不幸的是，我不知道自那以后我有什么变化。
任何帮助，高度赞赏。提前致谢。
您的主QML文件中是否有PageStackWindow或Page？您是否导入QtQuick 1.0或1.1？ – fejd 2012-01-16 22:20:50
我的主要QML文件中既没有PageStackWindow也没有Page。我使用QtQuick 1.0。你认为导入QtQuick 1.1可以解决问题吗？我会试一试。 – endowzoner 2012-01-17 10:13:17
Qt 4.7.4可能包含Qt Quick 1.1，但无论如何它都可能包含1.0。当我在一个文件中包含1.1和另一个文件时，我遇到了问题。如果您在根项目中添加Component.onCompleted {//获取组件状态}，是否会在控制台中获得任何日志输出？否则，运行和部署日志对我来说看起来不错。我建议Page或PageStackWindow的原因是我见过的大多数例子似乎都使用它们，或者说Window。但既然你说过它在那之前工作，那可能不是问题。 – fejd 2012-01-17 21:00:49
