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。

QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets TARGET = HelloCTKWidget TEMPLATE = app #CTK安装路径 CTK_INSTALL_PATH = /usr/local/CTK #CTK插件相关库所在路径 CTK_LIB_PATH = $$CTK_INSTALL_PATH/lib/ctk-0.1 #CTK插件相关头文件所在路径 CTK_INCLUDE_PATH = $$CTK_INSTALL_PATH/include/ctk-0.1 LIBS += -L$$CTK_LIB_PATH -lCTKCore -lCTKWidgets INCLUDEPATH += $$CTK_INCLUDE_PATH SOURCES += main.cpp\ Widget.cpp HEADERS += Widget.h

2、使用CTK Widgets模块中的组件

#ifndef WIDGET_H #define WIDGET_H #include <QWidget> #include <QGridLayout> #include <ctkCheckablePushButton.h> #include <ctkCollapsibleButton.h> #include <ctkColorPickerButton.h> #include <ctkRangeWidget.h> #include <ctkCollapsibleGroupBox.h> #include <ctkCoordinatesWidget.h> #include <ctkTreeComboBox.h> #include <ctkSearchBox.h> #include <ctkDirectoryButton.h> #include <ctkCheckableComboBox.h> #include <ctkMaterialPropertyWidget.h> #include <ctkMatrixWidget.h> #include <ctkPathLineEdit.h> class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0) { m_layout = new QGridLayout(this); //复选按钮 m_ctkCheckableButton = new ctkCheckablePushButton(this); m_ctkCheckableButton->setText("ctkCheckablePushButton"); //可折叠按钮 m_ctkCollapsibleButton = new ctkCollapsibleButton(this); m_ctkCollapsibleButton->setText("ctkCollapsibleButton"); m_layout->addWidget(m_ctkCheckableButton, 0, 0, 1, 2); m_layout->addWidget(m_ctkCollapsibleButton, 0, 2, 1, 2); //颜色拾取器 m_ctkColorPickerButton = new ctkColorPickerButton(this); m_ctkColorPickerButton->setText("ctkColorPickerButton"); //滑块 m_ctkRangeWidget = new ctkRangeWidget(this); m_layout->addWidget(m_ctkColorPickerButton, 1, 0, 1, 2); m_layout->addWidget(m_ctkRangeWidget, 1, 2, 1, 2); //分组框 m_ctkCollapsibleGroupBox = new ctkCollapsibleGroupBox(this); m_ctkCollapsibleGroupBox->setTitle("GroupBox"); m_layout->addWidget(m_ctkCollapsibleGroupBox, 3, 0, 3, 4); //坐标组件 m_ctkCoordinatesWidget = new ctkCoordinatesWidget(this); //树形组合狂 m_ctkTreeComboBox = new ctkTreeComboBox(this); m_ctkTreeComboBox->addItems(QStringList() << "A" << "B"); m_layout->addWidget(m_ctkCoordinatesWidget, 6, 0, 1, 2); m_layout->addWidget(m_ctkTreeComboBox, 6, 2, 1, 2); //搜索框 m_ctkSearchBox = new ctkSearchBox(this); //目录按钮 m_ctkDirectoryButton = new ctkDirectoryButton(this); m_layout->addWidget(m_ctkSearchBox, 7, 0, 1, 2); m_layout->addWidget(m_ctkDirectoryButton, 7, 2, 1, 2); //带复选功能的组合框 m_ctkCheckableComboBox = new ctkCheckableComboBox(this); m_ctkCheckableComboBox->addItems(QStringList() << "A" << "B"); //路径行编辑框 m_ctkPathLineEdit = new ctkPathLineEdit(this); m_ctkPathLineEdit->addCurrentPathToHistory(); m_layout->addWidget(m_ctkCheckableComboBox, 8, 0, 1, 2); m_layout->addWidget(m_ctkPathLineEdit, 8, 2, 1, 2); //材料属性组件 m_ctkMaterialPropertyWidget = new ctkMaterialPropertyWidget(this); //矩阵组件 m_ctkMatrixWidget = new ctkMatrixWidget(this); m_layout->addWidget(m_ctkMaterialPropertyWidget, 9, 0, 1, 2); m_layout->addWidget(m_ctkMatrixWidget, 9, 2, 1, 2); setLayout(m_layout); } private: QGridLayout* m_layout; ctkCheckablePushButton* m_ctkCheckableButton; ctkCollapsibleButton* m_ctkCollapsibleButton; ctkColorPickerButton* m_ctkColorPickerButton; ctkRangeWidget* m_ctkRangeWidget; ctkCollapsibleGroupBox* m_ctkCollapsibleGroupBox; ctkCoordinatesWidget* m_ctkCoordinatesWidget; ctkTreeComboBox* m_ctkTreeComboBox; ctkSearchBox* m_ctkSearchBox; ctkDirectoryButton* m_ctkDirectoryButton; ctkCheckableComboBox* m_ctkCheckableComboBox; ctkMaterialPropertyWidget* m_ctkMaterialPropertyWidget; ctkMatrixWidget* m_ctkMatrixWidget; ctkPathLineEdit* m_ctkPathLineEdit; }; #endif // WIDGET_H

#include "Widget.h" #include <QApplication> int main(int argc, char *argv[]) { QApplication a(argc, argv); Widget w; w.show(); return a.exec(); }

3、CTK Widgets应用编译结果

4、CTK Widgets学习示例

CTK Widgets测试代码位于CTK/Libs/Widgets/Testing/Cpp中，可以作为学习示例。
