So, I'm completely stuck. Been searching and googeling for the last few days.
In my mainwindow, I have Loggin functions, and after pressing the "Loggin" button, and username and password is correct, I open a second dialog "loggedinasteacher".
When in this second dialog window I need the id-number corresponding to the username and password. This IdNr I need to send from my mainwindow to my second dialog.
And this is the problem, I can't pass it.
This is what I got so far:
mainwindow.h

#define MAINWINDOW_H
#include <QMainWindow>
#include <QObject>
#include "logginregister.h"
#include "loggedinasteacher.h"

}

{

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private slots:
void on_pushButton_loggIn_clicked();
private:
Ui::MainWindow *ui;
LogginRegister lr;
LoggedInAsTeacher *loggedTeacher;
int m_idNr;
};
#endif // MAINWINDOW_H
mainwindow.cpp
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QString>
#include <QMessageBox>
#include "loggedinasteacher.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
lr.AddTeacher("Prof. Snape", "PrSn", "123456", "Teacher", 20000);
this->loggedTeacher = new LoggedInAsTeacher(&this->lr, this);
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow:n_pushButton_loggIn_clicked()
{
std::string username = ui->lineEdit_userName->text().toStdString();
std::string password = ui->lineEdit_passWord->text().toStdString();
bool correctLoggIn = false;
correctLoggIn = lr.loggInCheck(username, password);
if(correctLoggIn != false)
{
m_idNr = lr.GetTeacherId(username, password);
this->hide();
loggedTeacher->show();
}
else
{
QMessageBox::warning(this, "Login", "Username or password is incorrect");
}
}

ui->label_userNameInfo->setText(QString::fromStdString(lr->TeacherDisplayUserName(t_idNr)));
}
LoggedInAsTeacher::~LoggedInAsTeacher()
{
delete ui;
