我的CMakeLists.txt看起来像:

cmake_minimum_required(VERSION 2.8)
if(CMAKE_BUILD_TYPE STREQUAL Release)
  SET(CMAKE_BUILD_TYPE Release)
  SET (PROJECT_NAME location_recognition)
  message("Release mode")
else()
  SET(CMAKE_BUILD_TYPE Debug)
  SET (PROJECT_NAME location_recognition)
  SET(CMAKE_CXX_FILES "-g -Wall")
  message("Debug mode")

endif()

我有一个使用CMake 2.8.9的相对简单的Qt 5.0项目:

的CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.9)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
project(hello-world)

find_package(Qt5Widgets REQUIRED)
qt5_wrap_ui(hello-world_UI MainWindow.ui)

add_executable(hello-world MainWindow.cpp main.cpp ${hello-world_UI})
qt5_use_modules(hello-world Widgets)

MainWindow.h:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
    class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

    public:

        MainWindow();
        virtual ~MainWindow();

    private:

        Ui::MainWindow * const ui;
};

#endif // CMAINWINDOW_H

MainWindow.cpp:

#include "MainWindow.h"
#include "ui_MainWindow.h"

MainWindow::MainWindow()
    : ui(new Ui::MainWindow)
{
}

MainWindow::~MainWindow()
{
    delete ui;
}

main.cpp中:

#include <QApplication>
#include "MainWindow.h"

int main(int argc, char * argv[])
{ …

我创建了表单，将其保存在项目目录中。现在我想添加一些代码。所以，我创建了头文件：

#ifndef SORTDIALOG_H
#define SORTDIALOG_H

#include <QtWidgets/QDialog>
#include <QtWidgets/QWidget>


#include "ui_sortdialog.h"


class SortDialog: public QDialog, public Ui::SortDialog
{
    Q_OBJECT
public:
    SortDialog(QWidget *parent=0);
    void setColumnRange(QChar first, QChar last);
}

#endif // SORTDIALOG_H

在编写代码 Qt creator 看到 ui_sortdialog.h，例如，我可以看到“Ui”命名空间。但是当我试图编译器写到 ui_sortdialog.h 没有找到

C:\Qt\Qt5.1.1\Tools\QtCreator\bin\untitled2\sortdialog.h:8: error: ui_sortdialog.h: No such file or directory
 #include "ui_sortdialog.h"
                       ^

我正在使用Qt创建一个GUI应用程序; 我尝试hello world使用Qt并且它工作得很好,但是当我创建自定义列表小部件undefined reference to vtable时,我在编译时遇到错误:

我正在使用eclipse和c ++

#ifndef QMENUFILTER_H_
#define QMENUFILTER_H_
#include <qmenu.h>
class CustomMenuFilter : QMenu
{
    Q_OBJECT
public:
    CustomMenuFilter () ;
    ~CustomMenuFilter() ;
private:
    QMenu FilterMenu;
    QAction *AddFilterAct ;
    QAction *DeleteFilterAct ;

     Q_SLOT
      void contextMenuEvent(QContextMenuEvent *event);
};
#endif /* QMENUFILTER_H_ */


#include "QMenuFilter.h"
CustomMenuFilter::CustomMenuFilter():QMenu()
{
    DeleteFilterAct = new QAction("DeleteFilter" , this);
    AddFilterAct = new QAction("AddFilter" , this);
    AddFilterAct->setText("AddFilter");
    DeleteFilterAct->setText("DeleteFilter");
}
