[praveenhi5]

In mainwindow constructor i am creating the member variable
kkkk= new Exp_IRIG_EMIT;

i am connecting the signal for updating progressbar range and value

calling initialize function to create thread in dll. and it will be loop
kkkk->Initialize();


click on ABORT push button on_pushButton_clicked() function get called

In side function i am calling signal to abort the thread

if i use kkkk object to abort its not calling abort signal

signal is get called when i create a new object with Exp_IRIG_EMIT.
