Parent Widget scope

[_Jack_]

Hi, probably this question was discussed before, but I do not find the answer in the forum archive...
Short: I need to access the parent Widget scope from a child widget...
The code I use is the follow, in the child widget :

foreach (QWidget *widget, QApplication::topLevelWidgets())
       {
       this->myMainForm = qobject_cast<MainForm *>(widget);
       if(this->myMainForm)
         {
         break;
         }
       }
 
    this->myMainForm->parentivar;

foreach (QWidget *widget, QApplication::topLevelWidgets())
       {
       this->myMainForm = qobject_cast<MainForm *>(widget);
       if(this->myMainForm)
         {
         break;
         }
       }

    this->myMainForm->parentivar;

To copy to clipboard, switch view to plain text mode 

The code works, but is it the correct and best approach to access a parent widget ivar, from a child widget ?
Thank you in advance for the answer.

just use the parent() method.
