You should be able to use QString::fromUtf8() for this: http://doc.qt.io/qt-5/qstring.html#fromUtf8

Could you please be so kind as to give me an example of what one of my icons would look like with the QString::fromUtf8() code? For example: 👦👶👧

Allanis

Sure. I'm not sure exactly what you mean. Do you want an image or a code example? either way I whipped up a quick example to demonstrate what it would look like. Here's an image.

Given that your first post mentioned you where visually impaired, I think I may have misunderstood your meaning, so here's an example in code:

  QRadioButton* rb = new QRadioButton();
  QString str = QString::fromUtf8("<Utf-8 code> Button Name");
  rb->setText(str);

Where <Utf-8 code> = the character you wish to display.
Pretty sure there is a nicer way to do it. But I'm off to bed. That should get you started though.

So are you thinking I should write something like:
QRadioButton* rb = new QRadioButton();
QString str = QString::fromUtf8("<👰> Button Name");
rb->setText(str);
And for "Button Name", would it be something like:
QRadioButton* rb = new QRadioButton();
QString str = QString::fromUtf8("<👰> Bride");
rb->setText(str);
Something along those lines?

Allanis

Yeah that will work. But remove the <> from around your unicode character. I only placed them their as placeholder. It will work by placing the unicode character in your source file as you have done, but I would recommend finding the value for it instead. I'm replying from my phone so I can't look ot up for you.

By value, do you mean the Unicode value? Or do you mean the hexidecimal value? I'm confused!

Sorry, I wasn't too clear. You should use the UCN for example: '\u2639' will represent ☹
There can be problems with this as compilers are required to support only the basic source characters. I'm not sure if Qt gives you much help in way of UCN's so if it doesn't display the character for you, use the literal '☹' in your source, and perhaps see if someone else can help you with the use of UCN as I'm not so sure without reading up on it. Perhaps also try reading up on character sets to understand encodings.

Edit:
I just checked up the code for 👧

  QString str1 = QString::fromUtf8("\U0001F467 Button 1");

So for Bride:

QString str1 = QString::fromUtf8("\U0001F470 Button 1");
-> Set Text = "Bride";

Allanis

@Annabelle said in Qt Programming Language:

\U0001F470

That's right. You've got it.

@Allanis said in Qt Programming Language:

So would this look right?

QString str1 = QString::fromUtf8("\U0001F470 Button 1");
-> Set Text = "Bride";
Not quite sure how to do the "Set Text" part, so I did the best I could when writing the code. So how would I compile the full version of the radio button? Would it look something like this?
QRadioButton *button = new QRadioButton ("Bride", this);
QString str1 = QString::fromUtf8("\U0001F470 Button 1");
-> Set Text = "Bride";

Allanis

QRadioButton* button = new QRadioButton();
QString str1 = QString::fromUtf8("\U0001F470 Bride");
button->setText(str1);

I would suggest reading a book to get yourself better acquainted with C++. Otherwise you will encounter many pitfalls.

Are there any books out there that are available in Braille? Since that's the primary format which I read. If that's not possible, is there a .chm help file that can explain the language in detail?

Allanis

It may be difficult to find such a technical book in Braille. I had a look but came up empty. You can find a copy of "C++ gui programming with qt4 2nd edition" in .chm.

https://github.com/sherlock/qt?files=1

I think your screen reader should be ok to read epub? If so you could pickup most textbooks from amazon or something.

I tried searching for the .chm file "C++ gui programming with qt4 2nd
edition" on the link you provided, but it says "No Matching Files Found". Where do I go next?

Hi, it is hidden inside a download button
this is direct link

I downloaded the .chm file, but now when I attempt to read any of the topics, it seems there's nothing in them. Is there something wrong with the file?

@Annabelle
Hi
Yes it seems that at least on windows 10, only the toc is there -
nothing is shown when you click on a topic.

If pdf is ok, here is direct link

Allanis

Sorry if I provided a bad link. (Didn't really download to check it).
See if your screen reader can read epubs ok. And you can find all you need on amazon. (Alternate outlets are available too.)

This machine I'm on is Windows XP.
My screenreader doesn't read PDF's.
What are EPubs?
Would I have to pay to find it on Amazon? If so, how much?

Would finding a pdf that would read her all the text from a basic C++ book work?

Then use Jaws to google examples or terms that she doesn't understand?

EPUB is an e-book file format with the extension .epub that can be downloaded and read on devices like smartphones, tablets, computers, or e-readers.

Which book of Basic C++ are you thinking of? PDF's in general don't work with my screenreader. .chm's, .txt's, and .doc's work just fine.
