GUI Window doesnt close

[plopes21]

Hi everybody.

I have a problem with windows (widgets) in qt.

In my mainwindow.cpp has

th = new QThread;
 features = new Features(&Manager);
 features ->moveToThread(th);
 th->start();
 
Hardware cl(status,&Manager,features,this);
          a.exec();

th = new QThread;
 features = new Features(&Manager);
 features ->moveToThread(th);
 th->start();

Hardware cl(status,&Manager,features,this);
          a.exec();

To copy to clipboard, switch view to plain text mode 

The hardware class call other widgtet. This widget has a cancel button with done(REJECTED);
But the window(hardware) doesnt close.
