          i used qDebug() << "focus widget " << qApp->focusObject(); at button click event.

          it doesn't fire at first time . but at second time click on Button "a" i get "focus widget QPushButton(0x26bbc00, name= "Buttona")" log .

          i think at first time my keyboard widget doesn't get activate. after click on widget anywhere it gets activate and after that it works proper.

          how to solve this issue.?

            Hi,

            from my experience, this behaviour comes from the focus shift,

            you click a button and than it gets the focus a and only than the clicked mechanimn works.

            IIRC, you can change that a couple of different ways.

            the following comes to my mind:

            • Chaning the signal from clicked to released
            • Subclassing QPushButton and manually emitting the pressed signal during focus in event

            Be aware of the Qt Code of Conduct, when posting : https://forum.qt.io/topic/113070/qt-code-of-conduct


            Q: What's that?

            Q: What does it do?
            A: It turns blue.

              Thank you for your reply.

              1. At the first time my Push button click event is not getting fired so released event is also not working.
              2. I have implemented focus in event but at first time its also not getting emitting.

                Hi
                for my keyboard, I find it needed to have
                NoFocus for focusPolicy on the buttons or they steal focus from Lineedit.

                    It may be a silly question, does it happen with all the buttons of your keyboard?
                    Are you sure that the first time you push on a button of your keyboard the slot keyboardHandler() gets called?

                      Yes, it happens with all the buttons of a keyboard. slot keyboardHandler() does not get called for the first time. another thing I observed that when I called a keyboard on QPushbutton clicked event then keyboard works properly. this issue happens with QlineEdit Only.

                        I would call lineEditkeyboard->setLineEdit(line) only when the lineEdit gets the focus.
                        In addition, in the setLineEdit(), I would call this->setFocusProxy(line). In order to avoid your keyboard to steal the focus from your linedit.

                          one more thing to share when I called keyboard widget with a show() like
                          lineEditkeyboard->setLineEdit(line);
                          lineEditkeyboard->show();

                          the keyboard works properly but when I called Keyboard like

                          lineEditkeyboard->setLineEdit(line);
                          lineEditkeyboard->setWindowModality(Qt::ApplicationModal);
                          lineEditkeyboard->show();

                          then I face the same issue of the first click.

                            hi, we need to find out what is happening.
                            please do
                            qDebug() << "focus widget " << qApp->focusObject();
                            which tells us when you open the keyboard, who has focus.
                            Meaning who will get the keys if u type.
                            I think you have something that steals keyboard focus when u open the
                            lineEditkeyboard

                              as you said I have done same when keyboard widget is shown.
                              output is

                              DBG default: focus widget QLineEdit(0x227ca90, name = "lineEdit")

                              lineEdit is Nothing but the QLineEdit on Keyboard widget.

                                    so the widget appear frozen for a moment ?
                                    Do you have any kind of loops in constructor or anything like that ?

                                          As I mentioned Previously when I set WindowModality of Keyboard widget to QApplicationModal I face this First Click issue otherwise it works fine. but if I didn't set windowModality then Keyboard goes back to the parent widget.

                                          **lineEditkeyboard->setWindowModality(Qt::ApplicationModal); **
