我最近開始通過一個C++ Gui編程與Qt 4書籍。包含/ Qt頭文件被棄用
但是,我無法越過第一個教程。
#include <QApplication>
#include <QTextEdit>
int main(int argv, char **args)
{
QApplication app(argv, args);
QTextEdit textEdit;
textEdit.show();
return app.exec();
}
每次我嘗試編譯,我得到這樣的:
C:\Qt\4.8.0\andrew>qmake -project
C:\Qt\4.8.0\andrew>qmake
C:\Qt\4.8.0\andrew>make
mingw32-make -f Makefile.Debug

由於我是新來的Qt和相當新的編譯,我認爲錯誤是我的結束。我是否聲明標題錯誤或什麼?
我.pro文件看起來是這樣的:

感謝
您是否嘗試過使用'#include'和'#include '?我還沒有嘗試過4.8,但他們可能只是想讓你通過_module_工作。 –
好吧,我試過了,得到了同樣的結果。我試圖編譯的這個特定教程直接來自Qt網站。我應該提到的一件事是,在Qt Creator中它說我的頭文件都不存在。我是否必須定義標題的完整路徑? –
如果在線和您的.pro文件的內容是否可以添加到確切教程的鏈接? –
