How to access parents variables

[revellix]

Hi Folks,

I don't get it. I have a QWidget and a QThread(*parent). Now the QWidget starts the QThread(*parent). In this QThread I want to access the variables in the QWidget. Imagine the QWidget holds an iserinput like QLineEdit.

Finally I have two Headers:

#1.

#include ...
 
class UserInput : public QWidget
{
    Q_OBJECT
public:
    explicit UserInput(QWidget *parent = 0);
 
    QLineEdit *inputLine;
}

#include ...

class UserInput : public QWidget
{
    Q_OBJECT
public:
    explicit UserInput(QWidget *parent = 0);
    
    QLineEdit *inputLine;
}

To copy to clipboard, switch view to plain text mode 

#2

#include ...
 
class algorithmus : public QThread
{
    Q_OBJECT
public:
    explicit algorithmus(QWidget *parent)

#include ...

class algorithmus : public QThread
{
    Q_OBJECT
public:
    explicit algorithmus(QWidget *parent)

To copy to clipboard, switch view to plain text mode 

Now in the Contructor of the QWidget

....
 
    calc = new algorithmus(this);

....

    calc = new algorithmus(this);

To copy to clipboard, switch view to plain text mode 

Finally I want to access the QLineEdit in the QWidget for the calculation in QThread:

....
 
    return [U]this->parent()->inputLine.toInt()[/U] + 1000; //f.e.

....

    return [U]this->parent()->inputLine.toInt()[/U] + 1000; //f.e.

To copy to clipboard, switch view to plain text mode 

Is this even possible?? I am a newbie
