Modules

Module Summary

A module is a selection of projects (also called components) which form a logical group based on a limited number of features to which they contribute. A module can contain libraries, plug-ins, applications and server components.

More details

浏览器

OS X

通过 Qt Online Installer for OS X

vim /etc/profile

export PATH=/Users/huihoo/Software/Qt/5.4/clang_64/bin:$PATH
或 export PATH=/Users/huihoo/Software/Qt/5.4/android_armv7/bin:$PATH

测试

$ qmake -v
QMake version 3.0
Using Qt version 5.4.0 in /Users/huihoo/Software/Qt/5.4/clang_64/lib

Debian

vim /etc/profile

#Qt
QTDIR=/home/huihoo/Qt/5.2.1/gcc_64
PATH=$QTDIR/bin:$PATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QTDIR PATH LD_LIBRARY_PATH

source /etc/profile
updatedb
qmake -v
QMake version 3.0
Using Qt version 5.2.1 in /home/huihoo/Qt/5.2.1/gcc_64/lib

Eclipse

Qt Eclipse Integration

VS

Qt Visual Studio Integration

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

http://qtnode.net/wiki/Qt4_with_Visual_Studio

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

apt-get install libqt4-dev

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)

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.
