可以不用qt designer来加载qwt里面的控件

3、demo：

.pro文件：

QT+= core gui

TARGET= qwt_test

TEMPLATE= app

SOURCES+= main.cpp\

mainwindow.cpp

HEADERS+= mainwindow.h

FORMS+= mainwindow.ui

LIBS+= -L "C:\QtSDK\Desktop\Qt\4.8.1\mingw\lib" -lqwt

INCLUDEPATH+= "C:\QtSDK\Desktop\Qt\4.8.1\mingw\include\QWT"

#qwtsetting

QWT_ROOT= C:/Qwt-6.1.2

LIBS+= -L "D:\QtSDK\Desktop\Qt\4.8.1\mingw\lib" -lqwt

INCLUDEPATH+= "D:\QtSDK\Desktop\Qt\4.8.1\mingw\include\qwt"

include( ${QWT_ROOT}/features/qwt.prf)

#endqwt setting

.h文件

#ifndefMAINWINDOW_H

#defineMAINWINDOW_H

#include<QMainWindow>

#include"qwt_plot.h"

namespaceUi {

classMainWindow;

}

classMainWindow : publicQMainWindow

{

Q_OBJECT

public:

explicitMainWindow(QWidget*parent = 0);

~MainWindow();

QwtPlot*qwtPlot;

private:

Ui::MainWindow*ui;

};

#endif// MAINWINDOW_H

.cpp

#include"mainwindow.h"

#include"ui_mainwindow.h"

MainWindow::MainWindow(QWidget*parent):

QMainWindow(parent),

ui(newUi::MainWindow)

{

//ui->setupUi(this);

this->resize(800,480);

qwtPlot= newQwtPlot(this);

qwtPlot->setObjectName(QString::fromUtf8("qwtPlot"));

qwtPlot->setGeometry(QRect(0,20,400,200));

}

MainWindow::~MainWindow()

{

//delete ui;

}

运行结果：
