I want to view my QTextEdit from class A in mainLayout in class B.

[inger]

How is it possible?
I have a project with several classes. In class A I make the layout. In class B I get the signals and make a QTextEdit, named received_msg, that I want to show in class A' s layout, called mainLayout.

How is it possible?

How can I make the connection?

You ask the object of class A (let's call it ObjectA) a pointer to its layout B->layoutPointer = ObjectA->layout() ... or something similar, if ObjectA created it somewhere else.

After that you just add your field to that layout B->layoutPointer->addWidget(B->received_msg).

Thanks.

I really dont understand what to do. Will you please help me further.

my main() is:

#include <QtGui/QApplication>
#include "overfore.h"
#include "vindu.h"
#include <QObject>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Overfore ov;
    return a.exec();
}

#include <QtGui/QApplication>
#include "overfore.h"
#include "vindu.h"
#include <QObject>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Overfore ov;
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

my overfore.cpp is:

#include "overfore.h"
#include "ui_overfore.h"
 
Overfore::Overfore(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Overfore)
{
    ui->setupUi(this);
    textOverfore = new QTextEdit;
    textOverfore->append("Hello");
    Vindu *vindu = new Vindu;
    vindu->layout();
}

#include "overfore.h"
#include "ui_overfore.h"

Overfore::Overfore(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Overfore)
{
    ui->setupUi(this);
    textOverfore = new QTextEdit;
    textOverfore->append("Hello");
    Vindu *vindu = new Vindu;
    vindu->layout();
}

To copy to clipboard, switch view to plain text mode 

and my vindu.cpp is:

#include "vindu.h"
 
Vindu::Vindu(QWidget *parent) :
    QWidget(parent)
{
    QPushButton *button = new QPushButton("button");
    textfield = new QTextEdit;
    QHBoxLayout *buttonLayout = new QHBoxLayout;
    buttonLayout->addWidget(button);
    buttonLayout->addWidget(textfield);
 
    setLayout(buttonLayout);
    setVisible(buttonLayout);
}

#include "vindu.h"

Vindu::Vindu(QWidget *parent) :
    QWidget(parent)
{
    QPushButton *button = new QPushButton("button");
    textfield = new QTextEdit;
    QHBoxLayout *buttonLayout = new QHBoxLayout;
    buttonLayout->addWidget(button);
    buttonLayout->addWidget(textfield);

    setLayout(buttonLayout);
    setVisible(buttonLayout);
}

To copy to clipboard, switch view to plain text mode 

What I really want is when I push "button" in class Vindu, I want the "textfield" from class Overfore to be shown in the field textOverfore in object vindu class Vindu. The variables are defined in the header files.
