    Default QT GUI Thread

    I have a problem with assigning a parent to the thread in the constructor of the dialog constructor:
    Qt Code:
    1. Dialog::Dialog(QWidget *parent) :
    2. QDialog(parent),
    3. ui(new Ui::Dialog)
    4. {
    5. ui->setupUi(this);
    6. thread_ptr=new Mythread(this); // <------------ here is the problem
    7. connect(thread_ptr,SIGNAL(valueChanged(int)),this,SLOT(On_value_changed(int)));
    8.  
    9. }
    To copy to clipboard, switch view to plain text mode 
    The error as follows:

    Qt Code:
    1. error: no matching function for call to 'Mythread::Mythread(Dialog*)'
    2. thread_ptr=new Mythread(this);
    3. ^
    To copy to clipboard, switch view to plain text mode
