Get screensize

[sierdzio]

Yeah I'm right but I shouldn't be :D RTL should not invert numbers, as far as I know, only regular text.

Perhaps this will work better (https://doc.qt.io/qt-5/qlocale.html#toString-6):

QLocale::toString(size.width()) + " x " + QLocale::toStringsize.height())

I think somewhere you have indeed set for Right-to-Left text output! Change your string " x " over to " <<< " and see which direction those chevrons come out --- is it indeed >>>?!

thank you for your answer.

chevrons?

what do i need to do?

I told you. Change your string " x " to " <<< ", how much clearer can I be?

msgBox.setText(QString::number(size.width()) + " <<< " + QString::number(size.height()));

EDIT I'm sorry, my bad, I've just realized I was thinking too literally, like a mirror!

Try:

msgBox.setText(QString::number(size.width()) + " abc " + QString::number(size.height()));

I want to know whether that comes out as abc or as cba?

@JonB

it return: cba

[JonB]

@Natural_Bugger
Yup! So we are all agreed: there is right-to-left going on here, the results of the screen size are correct but are being printed right-to-left! Not my area, but that is what needs sorting out....

[sierdzio]

@Natural_Bugger ok it's not a static method, eh.

Then:

QLocale locale;
msgBox.setText(locale.toString(size.width()) + " x " + locale.toStringsize.height()));

@JonB @sierdzio

i found the error.

i used a custom button class, i found online and it contains a method to reverse the text.

void CustomButton::reverseText()
{
    QString buttonText = text();
    std::reverse(buttonText.begin(), buttonText.end());
    setText( buttonText );
}

: )

thank you both

@Natural_Bugger
Using a custom button which calls reverse is not a good place to start from....

But I don't understand, the code you gave us uses QMessageBox::setText(), which is what we looked at, what has that got to do with any custom button, or the reverseText() method?

[sierdzio]

Hah, ok good that you've found it. Happy coding!
