How I Can change text on the button

Could you post MainWindow declaration.

If you use MainWindow that was created by QtCreator wizard then
@
ui->pushButton->setText("Hello");
@

When i write @ ui->@ i see "ui is not declarate"

There is no MainWindoww include in the source file.
@
#include "MainWindoww.h"

void ReWriteQuestion(string files) is not a part of MainWindoww.
That is why you are getting "ui is not declared".

Add it to the MainWindoww declaration and change the definition accordingly.

@
class MainWindoww : public ......

.....
void ReWriteQuestion(string files)
.....
};

@
void MainWindoww::ReWriteQuestion(string files)
{
......
ui->pushButton->setText("C++ rocks");
......
}
