Qt

Qt是跨平台的C++图形开发框架，发家史/辛酸史详细去看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">

1. include <QtGui/QApplication>
2. 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 新立得软件包管理器、Synaptic或者KPackageKit(Kubuntu默认的软件管理) 中搜索qt-creator,选择安装
  
• Firefox浏览器地址栏中输入apt:qt-creator
• 从 apt-get 命令安装：
  

sudo apt-get install qtcreator

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。

sudo apt-get install language-pack-kde-zh language-pack-kde-zh-base

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

<source lang="cpp">

1. include <KApplication>
2. include <KAboutData>
3. include <KCmdLineArgs>
4. include <KMessageBox>

int main (int argc, char *argv[]) {

   KAboutData aboutData(                                                           
                        // The program name used internally.                       
                        "tutorial1",                                               
                        // The message catalog name
                        // 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
                        "[email protected]");

   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:

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})

编译： <source lang="bash"> mkdir build && cd build cmake .. make ./tutorial1 </source>

KDevelop

KDE开发的IDE。

安装

• 从 新立得软件包管理器、Synaptic或者KPackageKit(Kubuntu默认的软件管理) 中搜索kdevelop,选择安装
  
• Firefox浏览器地址栏中输入apt:kdevelop
• 从 apt-get 命令安装：
  

sudo apt-get install kdevelop

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。

sudo apt-get install language-pack-kde-zh language-pack-kde-zh-base
