Better way to close old widget ui and open new widget ui

[TokaraForest]

Hello,

I have a push button and I want to open new ui that has a lineedit when I click that button. I managed it ,but it feels wrong because it is C language approach. Basically I added new widget class header file to original widget.h file. Then I created static object in push button's slot function and called object's show() function. When I click push button I see a new ui that has lineedit.

1. Is there a better way to achieve this ?
2. How can I get original widget class' member (QString text = "hello") from new widget class so that I can set text lineedit with that member ?

widget.h:

#ifndef WIDGET_H
#define WIDGET_H

#include <QWidget>
#include <QString>
#include "newform.h"

QT_BEGIN_NAMESPACE
namespace Ui { class Widget; }
QT_END_NAMESPACE

class Widget : public QWidget
{
    Q_OBJECT

public:
    Widget(QWidget *parent = nullptr);
    ~Widget();

private slots:
    void on_pushButton_clicked();

private:
    Ui::Widget *ui;
public:
    QString text = "hello";
};
#endif // WIDGET_H

widget.cpp:

#include "widget.h"
#include "ui_widget.h"

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

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


void Widget::on_pushButton_clicked()
{
    static newForm nf;
    this->hide();
    nf.show();
}

I have newform.h and newform.cpp files. I didn't change them. I will be very appreciated if you could help me.

@TokaraForest
Consider using a QStackedWidget to swap between what widget shown.

I don't know what you are doing with static newForm nf, but don't do it, and don't use static.

If you goal is to get a single text input, have a look at QInputDialog Class

    // pass text in c'tor and set it to your lineEdit in newForm.cpp
    newForm nf(text);
    // better show the window first before hiding the other
    nf.show();
    this->hide();

Thank you all ! I think @JonB 's suggestion will do the job since my goal is more comprehensive.
