Create the instance of the class wherever you want to get the value of that class and write public function to get the value of controls.
Ex: if classA contains the textedit and you want to access the value in classB use the instance of classA in class B and expose a method in classA to get the value of textedit and use it in classB by calling it.

Store the lineedit value in a variable and call it in the other form using extern below is the code snippet
int input1;
input = lineEdit->text().toInt();
In the next window.cpp use
extern int input1;
ineEdit->setText(QString::number(input1,10 ) );
Hope this helps

This question was asked before. Several times. Please use the search engine of the forum.
Solutions: A signal/slot connection or a pointer to the other dialog.
