Who is the parent of that dialog? How do you invoke the base class constructor in your dialog's constructor?

Hi
Thanks for your mail.

Dialog class name is MyDialog , the constructor is

MyDialog::MyDialog(QWidget *parent)
: QDialog(parent)
{

}


In Class Sample1.h file i included MyDialog.h header file and in Cpp file i placed one QPushButton . when we click that push Button , I want to display MyDialog class.


Here is the code which i wrote

void Sample1::showMydialog()
{
MyDialog *dlg=new MyDialog(this);
}

your MyDialog will be placed in the center of Sample1 Widget and not the screen.

Using QDesktopWidget you can get the size of the screen and then center your MyDialog.

Using QDesktopWidget you can get the size of the screen and then center your MyDialog.

AFAIR it will be enough, if you won't specify the parent.
