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?

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?

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?

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.)

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.

Excuse my jumping in. I am not a Qt professional, but I have been following this thread.

I hope you find success in however you approach programming. Even for a fully-sighted person C++ can be a bit daunting! May I suggest you have a brief look at this answer https://stackoverflow.com/a/3274617/489865, from a blind person reporting success with C++. There are also interesting posts in https://stackoverflow.com/questions/118984/how-can-you-program-if-youre-blind

Sorry, I hope that my reply it isn't off topic.
If you have and idea about an application to write and you think that it will be have a business or you already have customers that have asked for it don't worry.
You can design the ui (that it is easy) and you can ask to someone that knows C++ to write the code for you.
In the past I had a customer that did somehing like this.

I know how to write some of the code. It's the compiling part that I have trouble with. Also, I want to find a .chm help file that explains more of the codes of the Qt programming language in detail.
I haven't even started my company, so I don't have any customers as of this moment.

@Annabelle I can't help you with the chm part, but if you need help compiling I can help you figure out both qmake and cmake. Cmake being my preferred method of building Qt projects.

I build everything command line and rarely use IDEs. That sounds exactly what you're looking for if you are using notepad++ and just need a command line build.

@ambershark this topic was already covered. From context that she has used "compile" in various times I think she means that she isn't sure how to "fit all the pieces" together to get her code working.

JAWS is really good with the command line method. What are the commands I should put in when compiling my program?

@Allanis said in Qt Programming Language:

@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.

The above was posted four days ago. You have not compiled and tested your program at all?

No I haven't compiled and tested my program yet. I'm still writing up the code. I'm wondering if there's a .chm help file out there, which will list all the available possibilities for parameters like buttons, checkboxes, radiobuttons, tooltips, infotips, comboboxes, and edit boxes (both single line and multi line).

Allanis · wrote on 27 Sept 2017, 08:20

@Annabelle I struggled to find a .chm for you. But the best place you can look for help with the SDK is the official documentation: http://doc.qt.io/qt-5/

Check out:
http://doc.qt.io/qt-5/qtwidgets-module.html
You will find what you need in relation to Radio Buttons, tooltips etc..
