CTK框架——CTK Widgets快速入门
一、CTK Widgets模块简介
1、CTK Widgets模块简介
CTK Widgets模块是CTK封装的用于通用功能以及生物医学成像专用领域的Qt组件库。
CTK中所有部分都有大量的测试相关代码，在源码目录下Libs/xxx/Testin/Cpp目录中。
CTK官方文档：
http://www.commontk.org/docs/html/modules.html
ImageGallery演示了CTK Widgets模块大部分组件的效果：

2、CTK Widgets构成
CTK Widgets模块主要包含4部分：
A、DICOM Widgets：用于支持医学数字影像通信（DICOM）领域的应用
B、Visualization VTK Widgets：支持VTK的组件
C、Widgets：通用的功能组件
D、XNAT Widgets：支持XNAT的组件
目前只包含一个类ctkXnatLoginDialog。
XNAT是华盛顿大学神经信息学研究小组开发的开源成像信息平台，最初在华盛顿大学的巴克纳实验室开发，目前由哈佛大学开发。
二、CTK Widgets快速入门
1、导入CTK Widgets模块
CTKWidgets模块使用与其它第三方库一样。
创建一个QtGUI应用并在工程文件中加入CTKWidgets模块。
1 QT += core gui
2
3 greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
4
5 TARGET = HelloCTKWidget
6 TEMPLATE = app
7
8 #CTK安装路径
9 CTK_INSTALL_PATH = /usr/local/CTK
10
11 #CTK插件相关库所在路径
12 CTK_LIB_PATH = $$CTK_INSTALL_PATH/lib/ctk-0.1
13
14 #CTK插件相关头文件所在路径
15 CTK_INCLUDE_PATH = $$CTK_INSTALL_PATH/include/ctk-0.1
16
17 LIBS += -L$$CTK_LIB_PATH -lCTKCore -lCTKWidgets
18
19 INCLUDEPATH += $$CTK_INCLUDE_PATH
20
21 SOURCES += main.cpp
22 Widget.cpp
23
24 HEADERS += Widget.h
2、使用CTK Widgets模块中的组件
1 #ifndef WIDGET_H
2 #define WIDGET_H
