How to use string from a class in other classes

hi, im new, i have this code

Code:

---

QString cuenta;
cuenta=ui->lineEdit->text();

---

this string its declared in public members in a Class names log, i need use this string in other classes, please help me, im novice in C++ and new in QT, thanks in advance, greetings

Then you can post questions in General Programming Forum...

Code:

---

class LogClass {
public:
	QString textString;
 
	QString getTextString(void) const;
};
 
QString LogClass::getTextString(void) const
{
	return textString;
}
 
function()
{
	LogClass log;
 
	// Both does the same
	QString text_1 = log.getTextString();
	QString text_2 = log.textString
}

---

thnks, i was try this but i have a error in the compilation, i did this:

Code:

---

MainWindow.cpp
 
#include "LogClass.h"
 
 
 log login;
    QString showme;
    showme=login.cuenta;
    ui->mostrarcuenta->setText(showtime);

---

the error its this:

login was not declarate in this scope

thnks

show the log class definition, also I guess there should be more errors, post them too

ok, this its:

Code:

---

#ifndef LOG_H
#define LOG_H
 
#include <QMainWindow>
#include <QWidget>
#include "mainwindow.h"
#include <QSqlQuery>
#include <QKeyEvent>
 
namespace Ui {
    class log;
}
 
class log : public QMainWindow
{
    Q_OBJECT
 
public:
    explicit log(QWidget *parent = 0);
 
 
    QString cuenta;
    ~log();
 
private:
    Ui::log *ui;
    MainWindow m;
 
private slots:
   // void funcion::keyPressEvent( QKeyEvent* );
    void on_pushButton_clicked();
};
 
#endif // LOG_H

---

then, i call the Qstring cuenta so:

this code is located in mainwindow.cpp

Code:

---

log login;
QString showme;
showme= login.cuenta;

---

the compiler does not show other error

first point, don't use a standard name like log (it can conflict with log() function in math.h), use a different class name.

next the error might related to Ui::log class, not ::log class (note the scope), try including "ui_log.h" (or whatever is the ui file name is) in mainwindow.cpp
