    &MainWindow::on_ioGroup_clicked);

    OIC I missed that when OP said it was correct.

      ` Text ` = Text

        Interesting. I don't know and have never set a text color in any of my posts! :) @Pl45m4 post above with red text for Text is the first time I have seen any color.

        Oh, hang on! Like buttonClicked()? LMAO, until today's forum update that was in green, no wonder I didn't know about red! The "color" is just up to the forum style. The important thing is that code is in monospace font. Use the Code icon (</>) when you are typing in. Or

        `in-line codecharacters`
        

        ```

        multiline code
        multiline code
        

        ```
        First one is single-backtick inline, second one is triple-backtick above and below block.

          I use this text format every time I mention some Qt term or class. QPushButton, QObject, Q_OBJECT.
          So did/do you ;-)
          I don't know what exactly you did when writing these posts, but I used single backticks (don't know how they are called)
          ` QPushButton ` (now escaped to make them visible)

          LMAO, until today's forum update that was in green, no wonder I didn't know about red

          I could swear it was red before, with some kind of red-ish background.
          At least when used outside of a code section in regular paragraphs.

            @Pl45m4 Maybe. Whatever I thought the original question was how to write in red, rather than in monospace which happens to show as red!

              Thanks for the tip :)

              I finally found the Help button I was looking for yesterday that describes the markdown syntax.

                @Pfanne said in ui detect mouse event on objects:

                this worked:
                connect(ioGroup, &QButtonGroup::idClicked, this, MainWindow::on_ioGroup_clicked);

                Correct.

                finaly this worked:
                connect(ioGroup, SIGNAL(idClicked(int)), this, SLOT(on_ioGroup_clicked(int)));

                Since you had it correct first why change it?

                the first version:

                connect(ioGroup, &QButtonGroup::idClicked, this, MainWindow::on_ioGroup_clicked);
                

                is without the object ID, implementing the ID in this version a error occurse.

                  As I said earlier, you have to pass an address:

                  connect(ioGroup, &QButtonGroup::idClicked, this, &MainWindow::on_ioGroup_clicked);

                    You can see for yourself (when it's written in monospace) that in your
                    connect(ioGroup, &QButtonGroup::idClicked, this, MainWindow::on_ioGroup_clicked);

                    one method reference has a preceding & and the other does not, and thereby tell what you had is not correct.

                      connect(ioGroup, &QButtonGroup::idClicked, this, MainWindow::on_ioGroup_clicked);
                      

                      OK, I think I understand, but this try worked, without ID but it creates a event on every click.
                      Without the reference (&) to MainWindow....

                      But it´s OK, this try:

                      connect(ioGroup, SIGNAL(idClicked(int)), this, SLOT(on_ioGroup_clicked(int)));
                      

                      is exactly the way that I use (SIGNAL -> SLOT) for my other connections.

                      Thanks for your support!

                        But you should switch to the pmf syntax for your own sake.

                          should I use the pmf syntax only for object events or also for function events too?

                            What are object or function events from your perspective?
                            You can't connect events, you connect signals there.
                            And yes, use the function pointer connection style. Every time you make a signal connection
