vs2013+qt5.51+vtk 實現的 雙view，顯示並聯動操作
阿新 • • 發佈：2019-02-15
1.首先我們必須將QVTKWidget加入到Qt Designer，只需找到編譯好的vtk的release版本下的QVTKWidgetPlugin.dll，QVTKWidgetPlugin.exp，QVTKWidgetPlugin.lib放入到自己QT下的designer下即可（我的目錄是：F:\Qt\Qt5.5.1\5.5\msvc2013\plugins\designer）
2.寫好CmakeLists.txt
CMAKE_MINIMUM_REQUIRED( VERSION 2.8 ) PROJECT( qt ) #---------------------------------------------------------------------------------- FIND_PACKAGE( VTK REQUIRED ) FIND_PACKAGE( Qt5Widgets ) INCLUDE( ${VTK_USE_FILE} ) #---------------------------------------------------------------------------------- # 定義變數PROJECT_SRCS，其值為所列表的檔案列表，包含所有原始檔 SET( PROJECT_SRCS main.cpp ProjectMainWindow.cpp ProjectMainWindow.h ) # 定義變數PROJECT_UIS，其值為所列表的檔案列表，包含所有的ui檔案 SET( PROJECT_UIS ProjectMainWindow.ui ) # 定義變數PROJECT_MOC_HDRS，其值為所列表的檔案列表，包含所有Q_OBJECT的標頭檔案 SET( PROJECT_MOC_HDRS ProjectMainWindow.h ) #---------------------------------------------------------------------------------- # QT5_WRAP_UI通過QT的uic.exe生成UI檔案對應的ui_xxx.h檔案， # 並將生成的moc_xxx.h檔案列表儲存於變數PROJECT_UIS_H 裡 QT5_WRAP_UI( PROJECT_UIS_H ${PROJECT_UIS} ) # QT5_WRAP_CPP通過QT的moc.exe將包含的Q_OBJECT的檔案生成對應的moc_xxx.cxx檔案， # 並將生成的moc_xxx.cxx檔案列表儲存於變數PROJECT_MOC_SRCS裡 QT5_WRAP_CPP( PROJECT_MOC_SRCS ${PROJECT_MOC_HDRS} ) #---------------------------------------------------------------------------------- # Qt的MOC和UIC程式生成的moc_xxx.cxx和ui.xxx.h等檔案是存放在CMAKE的 # where to bulid the binaries 裡指定的目錄，所以必須把這些路徑包含進來 INCLUDE_DIRECTORIES( ${PROJECT_SOURCE_DIR} ${CMAKE_CURRENT_BINARY_DIR} ${VTK_DIR} ) # Qt程式如果有資原始檔（*.qrc）,要包含資原始檔， # qt5_add_resources 用的rcc.exe生成相應的qrc_xxx.cpp檔案， # 並將生成的檔案列表儲存於變數Project_RCC_SRCS裡 # set（Project_RCCS YourProjectName.qrc） # qt5_add_resources(Project_RCCS_SRCS ${Project_RCCS}) # 根據程式的cpp檔案、標頭檔案以及生成的ui_xxx.h、moc_xxx.cxx、qrc_xxx.cxx # 等生成可執行檔案，並連結Qt的動態庫（Qt的動態都定義在QT_LIBRARIES變數裡了） ADD_EXECUTABLE( qt ${PROJECT_SRCS} ${PROJECT_UIS_H} ${PROJECT_MOC_SRCS} ) TARGET_LINK_LIBRARIES ( qt ${VTK_LIBRARIES} #QVTK )
3.用cmake編譯
4.main函式
#include "ProjectMainWindow.h" #include <QTextCodec> //程式釋出時，可以不要註釋以下語句，編譯的時候就不會帶控制檯輸出視窗 //#pragma comment( linker, "/subsystem:windows /entry:mainCRTStartup" ) int main( int argc, char **argv ) { QApplication *app = new QApplication(argc, argv); ProjectMainWindow *window = new ProjectMainWindow(); window->show(); return app->exec(); };
5.ProjectMainwindow.h
#ifndef Project_MainWindow_H #define Project_MainWindow_H #include <QMainWindow> #include "ui_ProjectMainWindow.h" #include <vtkSmartPointer.h> class vtkImageViewer2; class vtkRenderer; class vtkEventQtSlotConnect; class vtkObject; class vtkCommand; class ProjectMainWindow : public QMainWindow { Q_OBJECT public: ProjectMainWindow(QWidget *parent = 0); ~ProjectMainWindow(); private: Ui::ProjectMainWindowClass ui; private slots: //響應開啟影象檔案的槽函式 void onOpenSlot(); private: vtkSmartPointer< vtkRenderer > m_pRenderder_left; vtkSmartPointer< vtkRenderer > m_pRenderder_right; vtkEventQtSlotConnect* m_Connections; }; #endif

顯示效果圖
無論點那個都可以使影象聯動
