Mouse & KeyBoard Event

Dear Friends,
I have a small problem, I want to close a QDialog if there is a MouseEvent in my application.
There are many Widget's and Buttons , I want to detect MouseEvent before them and close the dialog box, How can I do that? Can I detect mouseRelease or press event on QApplication.

Install an event filter on the application object.

if you want to close particular Dialog hard code like that

Code:

---

void className::mousePressEvent(QEvent *event)
{
 
dialogName->close();
 
}

---
