Qt Eclipse Integration

[编辑] VS

Qt Visual Studio Integration

Qt-logo.png is integrated with the Microsoft Visual Studio .NET and Eclipse integrated development environments. This means Qt programmers can use the IDE they are most comfortable with to do cross-platform development.

安装QT SDK 后，默认采用的是动态链接库的编译方式, 要生成静态的版本, 就需要自己重新进行编译. 

设置 QMAKESPEC 为 win32-msvc2008 或 win32-msvc2005 的环境变量
设置 QTDIR 环境变量 如: C:\Qt\2009.05\qt
加入 C:\Qt\2009.05\qt\bin 到 PATH中
打开一个 Visual Studio command prompt 命令窗口
echo %QMAKESPEC%
configure.exe --help
C:\Qt\2009.05\qt\mkspecs\win32-msvc2008\qmake.conf
QMAKE_LFLAGS            = -static
configure
nmake

常见错误 

cannot open input file 'QtCored4.lib'// 是因为没有进行静态编译. 需先进行前面的操作. Qt 2009.05


编译出的是类似 QtWebKitd4.lib, 而不是 QtWebKit4.lib // Qt 2009.05

编译出 QtWebKitd4.lib Failed to write the updated manifest to the resource of file QtWebKitd4.dll // Qt 2010.01

QtUiToolsd.lib没编译出来 ?

需要什么库就编译什么库, 如编译 SQLite3 

cd %QTDIR%\src\plugins\sqldrivers\sqlite
qmake "INCLUDEPATH+=C:\sqlite-3.6.22" "LIBS+=C:\Qt\2010.01\qt\plugins\sqldrivers\qsqlite.lib" sqlite.pro
nmake

在C:\Qt\2010.01\qt\plugins\sqldrivers下创建了qsqlite4.dll, qsqlite4.lib, qsqlited4.dll, qsqlited4.lib

PostgreSQL 

cd $QTDIR/src/plugins/sqldrivers/psql
qmake "INCLUDEPATH+=C:\pgsql-8.3.6\include" "LIBS+=C:\pgsql-8.3.6\lib\libpq.lib" psql.pro
nmake

在C:\Qt\2010.01\qt\plugins\sqldrivers下创建了 qsqlpsql4.lib, qsqlpsql4.dll, qsqlpsqld4.dll, qsqlpsqld4.lib

make: /usr/bin/uic-qt4: Command not found 

apt-get install libqt4-dev

[编辑] Code

Qt hello world 

#include <QtGui>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel label("Hello, world!");
    label.show();
    return app.exec();
}

Compiling and executing

1. Create a folder named Hello
2. Copy paste the above program as Hello.cpp in folder Hello
3. At Hello folder run 

 a. qmake -project
 b. qmake 
 c. make/gmake/nmake - as needed by OS and your compiler setups

4. Execute ./release/Hello (Or release\Hello.exe in Windows)

[编辑] Plugins

Qt provides two APIs for creating plugins:

  • A higher-level API for writing extensions to Qt itself: custom database drivers, image formats, text codecs, custom styles, etc.
  • A lower-level API for extending Qt applications.
