Re: [[SOLVED] Qt Visual Studio Add-in](Signal & Slots problems)

this is my .h file:

#pragma once

#include <QtWidgets/QMainWindow>
#include <QtWidgets/QTreeWidgetItem>
#include <QtCore/QUrl>
#include <QtWebKit/QWebElement>
#include <QtCore/QObject>

#include "ui_window.h"

class window : public QMainWindow, QObject
{
Q_OBJECT
public:
window(QWidget *parent = 0);
void detUrl(const QUrl &url);
void on_webView_loadFinished();
public slots:
void check();
private:
Ui::windowClass ui;
void examineChildElements(const QWebElement &parentElement,QTreeWidgetItem *parentItem);
};

when I compile that I have this error:
Severity Code Description Project File Line Suppression State
Error LNK2019 unresolved external symbol "public: void __cdecl window::check(void)" (?check@window@@QEAAXXZ) referenced in function "private: static void __cdecl window::qt_static_metacall(class QObject *,enum QMetaObject::Call,int,void * *)" (?qt_static_metacall@window@@CAXPEAVQObject@@W4Call@QMetaObject@@HPEAPEAX@Z) window C:\Users\Amin\Documents\Visual Studio 2017\Projects\window\window\moc_window.obj 1

I use VS 2017 C++ Qt, where is the problem?

@Aminmlp said in error lnk2019 in slot and signal qt visual studio 2017:

void check();

Did you implement it in your cpp file?
