Have no idea how to create multiple windows!

JonathanAV95

I've been trying ways to figure it out but i cant seem to get it working or get it seem to go in the right direction.

All i want to do is have my MainWindow simply show another window. For example, have a MainWindow with a QButton, that upon clicking it, will show another window that has perhaps a label. I have no idea how to approach this! I might be asking anyone a lo here but this issue is holding me up greatly since i cant seem to fully understand Qt yet! I'd appreciate it if anyone can help !

All you need to do to create a separate window in Qt is to create a QWidget (like QPushButton, QLabel, etc.) without a parent (meaning: parent == 0).

Or, alternatively, you can use QDialog.

I personally do not know how to approach this?
Here is the source code i have so far, were can i insert a QDialog:

login_window.h
@
#ifndef LOGIN_WINDOW_H
#define LOGIN_WINDOW_H

#include <QWidget>
#include <vector>

namespace Ui {
class LoginWindow;
}

class LoginWindow : public QWidget
{
Q_OBJECT

public:
explicit LoginWindow(QWidget *parent = 0);
~LoginWindow();

bool checkStudentElement(int &refString, std::vector<int> &refVector);

private slots:
void on_loginButton_clicked();

private:
Ui::LoginWindow *ui;
std::vector<int> *studentIDList;
};

#endif // LOGIN_WINDOW_H
@

login_window.cpp
@
#include "login_window.h"
#include "ui_loginwindow.h"

LoginWindow::LoginWindow(QWidget *parent) : QWidget(parent), ui(new Ui::LoginWindow)
{
ui->setupUi(this);

}

LoginWindow::~LoginWindow()
{
delete ui;
}

void LoginWindow::on_loginButton_clicked()
{
std::string student_ID = (ui->le_studentID->text()).toStdString(); //convert to string
//Must then check if it is already in the system

if(checkStudentElement(student_ID, studentIDList) == true) //need to run function for check
{
    ui->loginStatus->setText("Login Successful");
    break;
}else{
    ui->loginStatus->setText("Login Failed");
    studentIDList->push_back(student_ID); //push the ID into the vector

}

}

bool LoginWindow::checkStudentElement(int &refString, std::vector<int> &refVector)
{
int counter = refString.Length();
if(counter > refString)
{

}
for(int i = 0; i <= refVector.size(); i++)
{
    //Will loop thru the elements to check for similar vector
    if(/*refVector.()begin == refVector*/)
    {
        //if it contain it
        break;

    }else{
        return false;
    } //else make sure to return that value
}

}
