Qtcharts with visual C++

[awawawa]

Hi everybody!

I am working on a project on visual c++ and I try to add a form class with a QChartView inside. In this project :

• After adding the QtCharts directoy folder and linking qt5Charts.lib with my project,

• I draw a form with QtDesigner

• I add a Widget that I promote as a QChartView.

When I try to compile my project, I have some errors. The origin of these errors seems that in the generated ui_XXX.h of my form, the namespace qtCharts is not used. If I add it manually, the project will compile and seems to work well. The problem is that the line I add is deleted each time the ui_XXX.h is generated.

Can you, please, tell me, what point which will fixe this probleme that I forgot?

Here is some part of the code :

• Here is the class that I create :

#ifndef TEST_H
#define TEST_H
#include "ui_test.h"

class test : public QMainWindow
{
	Q_OBJECT
public:
	test(QWidget *parent = 0);
	~test();
private:
	Ui::testClass ui;	
};
#endif // TEST_H

This class contains a Ui::testClass element which is generated by the QtDesigner. Here is the code :

#ifndef UI_TEST_H
#define UI_TEST_H

#include <QtCore/QVariant>
#include <QtWidgets/QAction>
#include <QtWidgets/QApplication>
#include <QtWidgets/QButtonGroup>
#include <QtWidgets/QHeaderView>
#include <QtWidgets/QMainWindow>
#include <QtWidgets/QMenuBar>
#include <QtWidgets/QStatusBar>
#include <QtWidgets/QToolBar>
#include <QtWidgets/QWidget>
#include "QtCharts\qchartview.h"

QT_BEGIN_NAMESPACE

//using namespace QtCharts; I have to add this line if I want the compilation works

class Ui_testClass
{
public:
    QWidget *centralWidget;
    QChartView *widget; // without namespace this must be QtCharts::QChartView
    QMenuBar *menuBar;
    QToolBar *mainToolBar;
    QStatusBar *statusBar;

//BLA BLA BLA...

Hi.

Try in your test.h as follows:

#ifndef TEST_H
#define TEST_H

#include <QtCharts>
QT_CHARTS_USE_NAMESPACE

#include <QMainWindow>
#include "ui_test.h"

class test : public QMainWindow
{
[...]

Do not modify your ui_test.h.
