SIGNAL / SLOT problem between 2 classes

[Groot]

Hello all :)

I have 2 ui classes into an "Application" class

class Application
		{
		public:
			Application();
			Application(QString name, QString version);
			void run();

		private:

			QString name_;
			QString version_;

			/********* UI ********/
			Menu_ui menu_;
			Employee_sheet_ui employee_sheet_;

			/**********************/
		};

I want to show "employee_sheet_ when I press a button from "menu_"
ATM, I thought it was necessary to do like that:

void Application::run()
{
	menu_.show();

	QObject::connect(menu_.ui.pushButton, SIGNAL(clicked()), &employee_sheet_, SLOT(employee_sheet_.show()));
}

...but it doesn't work

Someone can explain me my error please?

Thanks a lot in advance :)

For information, my Enployee_sheet class:

#include <QWidget>
#include "ui_employee_sheet_ui.h"

class Employee_sheet_ui : public QWidget
{
	Q_OBJECT

public:
	Employee_sheet_ui(QWidget *parent = Q_NULLPTR);
	~Employee_sheet_ui();


	Ui::Employee_sheet_ui ui;

};

Your connect() is wrong => please take time to read documentation: https://doc.qt.io/qt-5/signalsandslots.html
And prefere using new connect syntax so you will get connection error at compilation time.

I have understand! i'm stupid! (thx Lelev)

I must remplace:

QObject::connect(menu_.ui.pushButton, SIGNAL(clicked()), &employee_sheet_, SLOT(employee_sheet_.show()));

to:

	QObject::connect(menu_.ui.pushButton, SIGNAL(clicked()), &employee_sheet_, SLOT(show()));

Yes, but as @KroMignon said it would be even better if you decided to change over to:

QObject::connect(menu_.ui.pushButton, &QPushButton::clicked, &employee_sheet_, &EmployeeSheet::show);
