[CLOSED] String and classes

? Offline

Hello, I have two classes

Class 1 = MainWindow

Class 2 = Dialog

Dialog contains textedit and should store string into MainWindow... How can I do that???

How it should looks like

Class 1
QString test;

Class 2
void Dialog::onButtonClicked{
test = uiDialog->textEdit->text();
}

Hi,

Add a getter to your dialog and retrieve the string after you have called exec on it

I would recommend going through Qt's examples and demos. You'll find a lot of valuable information to get you started

I was trying to find example on Google but not very successfully...

I used Refractor in Qt and it made Getter and Setter, but don't know what to do with it now...

Dialog .h
@#ifndef DIALOG_H
#define DIALOG_H
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDialog>

namespace Ui {
class Dialog;
}

class Dialog : public QDialog
{
Q_OBJECT

public:
explicit Dialog(QMainWindow *parent = 0);
~Dialog();
Ui::MainWindow *ui;
QString string;

QString getString() const;
void setString(const QString &value);

private slots:
void on_button_clicked();

private:
Ui::Dialog *uis;
};

#endif // DIALOG_H

@

Dialog .cpp
@#include "dialog.h"
#include "ui_dialog.h"
#include "ui_mainwindow.h"
#include "mainwindow.h"

Dialog::Dialog(QMainWindow *parent) :
QDialog(parent),
uis(new Ui::Dialog)
{
uis->setupUi(this);
}

Dialog::~Dialog()
{
delete uis;
}
QString Dialog::getString() const
{
return string;
}

void Dialog::setString(const QString &value)
{
string = value;
}

void Dialog::on_button_clicked()
{

}

Why would you need MainWindow::Ui in your dialog ?

@
QString Dialog::getString() const
{
return uis->myLineEdit->text();
}

void Dialog::setString(const QString &value)
{
uis->myLineEdit->setText(value);
}@

I would recommend reading Qt's documentation/tutorials/examples before going further. You'll get a better grasp on how things work

Oh I was testing something, thats why MainWindow::Ui is there...

Where exactly do I have to read??? I went through few documentations but none of them explained use of getter/setter...

I figured out I can design QDialog even without designer pretty well, therefore I won't need these functions at this moment...

Thanks anyways
