&MainWindow::on_ioGroup_clicked);

OIC I missed that when OP said it was correct.

Hi @JonB

Off topic question :
How to set text color as you do in red in your posts ?

` 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)

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!

@Pl45m4
Thanks for the tip :)

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

@JonB
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.

@Pfanne said in ui detect mouse event on objects:

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

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.

[Pfanne]

@JonB

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.

[Pfanne]

@Christian-Ehrlicher

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

[Pl45m4]

@Pfanne

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
