我在爲Harmattan部署使用Qt 4.7.4/QtQuick 1.0編寫的應用程序時遇到問題。 當模擬器中的所有內容都正確時，應用程序在諾基亞N9（MeeGo 1.2 Harmattan，版本PR1.1）上部署時不會繪製任何用戶界面。部署成功，應用程序可以在設備上的應用程序列表中找到，甚至可以在QtCreator中看到控制檯日誌輸出，但是沒有跡象表明應用程序實際在設備上運行 - 我可以自由瀏覽系統並打開其他應用程序，而QtCreator說我的應用程序正在運行。Qt應用程序不會在MeeGo上在諾基亞N9上繪製任何用戶界面
在QtCreator應用輸出圖說：

Found v1.4 driver, enabling brokenTexSubImage
而且繼承人的編譯輸出：

雖然編譯輸出可能會提供有關該錯誤的一些提示，我不知道是什麼出錯了。可笑的是，在一些早期的開發階段，應用程序在設備上工作。但不幸的是，我不知道自那以後我有什麼變化。
任何幫助，高度讚賞。提前致謝。
您的主QML文件中是否有PageStackWindow或Page？您是否導入QtQuick 1.0或1.1？ – fejd 2012-01-16 22:20:50
我的主要QML文件中既沒有PageStackWindow也沒有Page。我使用QtQuick 1.0。你認爲導入QtQuick 1.1可以解決問題嗎？我會試一試。 – endowzoner 2012-01-17 10:13:17
Qt 4.7.4可能包含Qt Quick 1.1，但無論如何它都可能包含1.0。當我在一個文件中包含1.1和另一個文件時，我遇到了問題。如果您在根項目中添加Component.onCompleted {//獲取組件狀態}，是否會在控制檯中獲得任何日誌輸出？否則，運行和部署日誌對我來說看起來不錯。我建議Page或PageStackWindow的原因是我見過的大多數例子似乎都使用它們，或者說Window。但既然你說過它在那之前工作，那可能不是問題。 – fejd 2012-01-17 21:00:49
