    So you can compile it already?
    Or is it the compiling part that is hard to do ?

    Can the JAWS read a command prompt ?

    I can make the source code, it's the compiling the finished program part that's hard. Yes, JAWS can read a Command Prompt. What do I do in there?

    @Annabelle Sorry, I was at work when I made my initial response to this thread. A more elaborate answer for you follows as I take it you are beginning in Qt and it may be difficult for you to look up resources.

    Given the scope of your project I think it will suffice to use a simple Qmake project file such as:

    myapp.pro

    TEMPLATE = app
    
    QT += widgets
    
    SOURCES += main.cpp \
        MainWindow.cpp \
        SpouseWidget.cpp
    
    HEADERS += \
        MainWindow.h \
        SpouswWidget.h
    
    OTHER_FILES += \
        anyotherfile.png
    

    You may need to make changes to this in order to fit the needs of your project, but this should be a good enough example for you.

    Once you have this in place, you can open up your favorite Command Line Interface (eg. cmd.exe for Windows).

    Type:

    qmake myapp.pro
    make
    

    Your compiler will generate a binary file for your application at this point.

    I hope this helps,
    Have fun.

      Another thing I'd like to do is make icons for the push buttons, radio buttons, combo boxes, and checkboxes. I'd like to find out, is it OK for me to use unicode symbols as icons? For example:
      In the welcome screen, there are the following Radio Buttons
      ⚭ (Wedding Ceremony Radio Button)
      ~β›² (Baptism Ceremony Radio Button)
      β›Ό (Funeral Ceremony Radio Button)
      For the Spouse Genders, there should be the following Icons:
      πŸ‘° (Bride Radio Button)
      🀡 (Groom Radio Button)
      For the Baptism Person Types, there should be the following Icons:
      πŸ‘¦πŸ‘ΆπŸ‘§ (Infant Radio Button)
      πŸ‘¦πŸ‘§ (Child Radio Button)
      πŸ‘¦πŸ‘¨πŸ‘§πŸ‘© (Youth Radio Button)
      πŸ‘¨πŸ‘΄πŸ‘©πŸ‘΅ (Adult Radio Button)
      For the Funeral Ceremony Types, there should be the following icons:
      ⚰ (Funeral Radio Button)
      ⚱ (Memorial Service Radio Button)
      Note that some of the icons are composed of two or more unicode characters put together, as I couldn't find separate unicode symbols to represent them.

        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: πŸ‘¦πŸ‘ΆπŸ‘§

            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.

            0_1506120620297_annabelle.png

            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("<πŸ‘°> Button Name");
              rb->setText(str);
              And for "Button Name", would it be something like:
              QRadioButton* rb = new QRadioButton();
              QString str = QString::fromUtf8("<πŸ‘°> Bride");
              rb->setText(str);
              Something along those lines?

                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!

                    πŸ‘°

                    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 πŸ‘§

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

                          So would this look right?

                          -> 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");

                              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?

                                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.

                                  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.

                                  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?

                                      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?

                                        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

                                          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.)
