Can you call QWidget::close

[soumya]

if i do that only one form will get closed and the other will be open i need to close both the forms together

Make 2nd one parent as first form and launch 2nd form as non-modal. Set the single closing slot where you are closing the parent form.

Else you can use QPrecess.

I am closing the form using keypress event if i press escape key from keyboard one of my form will be closed but i need to close both the forms together.

[navi1084]

use installEventFilter() from parent class and in eventFilter() check for the Keypressed event and ESCAPE Character. depending on that close everything

Are your forms custom widgets ?
If yes, you can override closeEvent of your widget and call qApp->quit().

Or yet another suggestion:

QWidget *a, *b;
...
a->setAttribute(Qt::WA_DeleteOnClose);
b->setAttribute(Qt::WA_DeleteOnClose);
connect(a, SIGNAL(destroyed()), b, SLOT(deleteLater()));
connect(b, SIGNAL(destroyed()), a, SLOT(deleteLater()));

QWidget *a, *b;
...
a->setAttribute(Qt::WA_DeleteOnClose);
b->setAttribute(Qt::WA_DeleteOnClose);
connect(a, SIGNAL(destroyed()), b, SLOT(deleteLater()));
connect(b, SIGNAL(destroyed()), a, SLOT(deleteLater()));
