    @jdent i mean setDefault will not work when there is a focus in the LineEdit.Appart from that it will work.If you add a shortcut it will work as well

      @Ronel_qtmaster ok. How can I set a shortcut for the ENTER key?
      I tried

      searchButton->setShortcut(QKeySequence::StandardKey::)
      

      but there is no key for ENTER or RETURN!

        @jdent did you try pushButton->setShortcut(QKeySequence(Qt::Key_Enter));

          @Ronel_qtmaster I tried it - no results.

          In MFC (Microsoft Foundation Classes) you can do this, I can't see why we can't do it in Qt...
          There must be a way!!

          When I press ENTER when inside the line edit, can't I take that keystroke and invoke the Search button?

              See my discussion with @Chris-Kawa on this in https://forum.qt.io/topic/155461/qlineedit-returnpressed-when-something-else-has-a-key_return-shortcut. It might be worth trying Qt::Key_Return here, I suspect what you call the Enter key is what Qt calls the Return key. But it may be that those two are interchangeable, not sure.

              It can certainly be done with a shortcut if you want, but I (think I) prefer @jsulm's suggestion of connecting returnPressed.

                    You might want to connect both Enter and Return. If I'm not mistaken, Enter is the key located in the NumPad area.

                      @SimonSchroeder See the discussion around https://forum.qt.io/topic/155461/qlineedit-returnpressed-when-something-else-has-a-key_return-shortcut/16 for the pointlessness/potential evilness of the NumPad Enter key ;-)
