Qt是跨平台的C++图形开发框架，发家史/辛酸史详细去看[http://zh.wikipedia.org/wiki/Qt  wikipedia],KDE环境就是用Qt开发的,最新的版本是Qt4.5.2。 

=编译环境=
== Hello World  ==
<source lang="cpp">
#include <QtGui/QApplication>
#include <QtGui/QLabel>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel label("Hello, world!");
    label.show();
    return app.exec();
}

</source>
编译：
 qmake -project 
 qmake 
 make

= Qtcreator  =

Qt4.5后 附带的轻量级IDE开发环境。

== 安装  ==

*从 '''[[UbuntuHelp:SynapticHowto/zh|新利得软件包管理器]][[UbuntuHelp:Synaptic|Synaptic]]'''或者[[Kpackagekit|KPackageKit(Kubuntu默认的软件管理)]] 中搜索qt-creator,选择安装<br /> 
*Firefox浏览器地址栏中输入apt:qt-creator 
*从 apt-get 命令安装：<br />
<pre>sudo apt-get install qtcreator
</pre>

== 中文界面  ==

如果安装的qtcreator是显示英文菜单，需要安装KDE的中文包才能显示中文菜单。 
<pre>sudo apt-get install language-pack-kde-zh language-pack-kde-zh-base
</pre> 
== 编译环境  ==
安装KDE 开发环境：
 sudo aptitude install kde-devel build-essential xorg-dev cdbs debhelper cmake \
 kdesdk-scripts subversion ssh xserver-xephyr doxygen dbus-x11 \
 libxml2-dev libxslt1-dev shared-mime-info libical-dev libgif-dev libssl-dev \
 libboost-dev libboost-program-options-dev libgpgme11-dev libxine-dev \
 libqimageblitz-dev libbz2-dev libdbus-1-dev libpam0g-dev libpcre3-dev \ 
 libkrb5-dev libsm-dev libclucene0ldbl libclucene-dev libjpeg62-dev \
 libxtst-dev xsltproc libxrender-dev libfontconfig1-dev automoc4
==Fakevim的使用==
在编辑器中按住ALT键同时按两下字母键V，就可以进入仿vim模式，在此模式下可以用vim的快捷键来编辑文件。退出vim模式可以连按两下字母键“，”。
The FakeVim feature can be triggered using Alt+V, V, enabling Qt Creator to emulate vim. In this mode, typical vim
commands can be used to edit text. To exit this mode, simply type “,,”.

== Hello World ==
<!-- KDE 4 Hello world -->

<source lang="cpp">
#include <KApplication>

                         "tutorial1",

                         // If null, program name is used instead.
                         0,
                         // A displayable program name string.
                         ki18n("Tutorial 1"),
                         // The program version string.
                         "1.0",
                         // Short description of what the app does.
                         ki18n("Displays a KMessageBox popup"),
                         // The license this code is released under
                         KAboutData::License_GPL,
                         // Copyright Statement
                         ki18n("(c) 2007"),
                         // Optional text shown in the About box.
                         // Can contain any information desired.
                         ki18n("Some text..."),
                         // The program homepage string.
                         "http://tutorial.com/",
                         // The bug report email address
                         "submit@bugs.kde.org");

    KCmdLineArgs::init( argc, argv, &aboutData );
    KApplication app;
    KGuiItem yesButton( i18n( "Hello" ), QString(),
                        i18n( "This is a tooltip" ),
                        i18n( "This is a WhatsThis help text." ) );
    KMessageBox::questionYesNo( 0, i18n( "Hello World" ),
                                i18n( "Hello" ), yesButton );
    return 0;
}
</source>
保存为main.cpp

现在需要一个CMakeLists.txt:
<pre>project (tutorial1)
find_package(KDE4 REQUIRED)
include (KDE4Defaults)
include_directories(${KDE4_INCLUDES})
set(tutorial1_SRCS main.cpp)
kde4_add_executable(tutorial1 ${tutorial1_SRCS})
target_link_libraries(tutorial1 ${KDE4_KDEUI_LIBS})
install(TARGETS tutorial1  ${INSTALL_TARGETS_DEFAULT_ARGS})</pre>
编译：
<source lang="bash">
mkdir build && cd build
cmake ..
make
./tutorial1
</source>

=KDevelop=
KDE开发的IDE。

==安装==
*从 '''[[UbuntuHelp:SynapticHowto/zh|新利得软件包管理器]][[UbuntuHelp:Synaptic|Synaptic]]'''或者[[Kpackagekit|KPackageKit(Kubuntu默认的软件管理)]] 中搜索kdevelop,选择安装<br> 
*Firefox浏览器地址栏中输入apt:kdevelop
*从 apt-get 命令安装：<br>
<pre>sudo apt-get install kdevelop
</pre> 
<br />

== 中文界面  ==
