Qt Programming Language

@Annabelle
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

@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..

@Annabelle My suggestion would be to start small. Split your project up into small pieces rather than look at it as a whole. I would use a Qwizard and make pages with the ability to select options and those options give out the results you are looking for.

I would get some Ebooks on C++ and learn the basics. Start with console applications and learn the basics of what you are trying to do. Make a text story with options and results base on what is written in the command prompt. Little stuff like this will help you understand the basics of programming.

When it comes to QT your gonna have to learn it from the ground up. Learn about the main..

So for example, in the Wedding Elements Page of the wizard, there are checkboxes with different titles, and I want to give a description of what each title means. Would I give it as a "QToolTip", or a "QWhatsThis"? The following is an example in HTML of one of the Checkboxes. The part that says "<span Data-tooltip" is the part where I need help converting to Qt, and is the part where I'm confused on which widget to choose, either QToolTip or QWhatsThis.

							<label class="checkbox">
								<span data-tooltip="It is required by law that a wedding ceremony include a Declaration of Intent to marry between the two individuals electing to join in the marriage contract." This can be in the form of an "I Do", where the minister/officiant asks questions to the soon-to-be married couple beginning with "Do you", and in turn, the couple answers "I do". Or it can be in the form of an "I Will", where the minister/officiant asks questions to the soon-to-be married couple beginning with "Will you", and in turn, the couple answers "I will.".>
									<input checked="checked" value="declarationOfIntent" id="elements-declaration-of-intent" type="checkbox">
									Declaration of Intent
								</span>
							</label>

It is incredible how many people are helping Annabelle.... But why?

What makes you ask why? Is it because I'm confused on whose advice to take? There are so many answers, I can't seem to tell which one to choose first. I mean, one wants me to make wizard pages. One wants me to use the Qt Creator to make the program, when my screenreader can't access it. one wants me to look at books that are most likely either only available as a physical print copy, or as a format which can't be read by my screenreader. One tells me I should go to outside sources other than the Qt website to find answers. Now my mind is in a whirlpool!

ambershark

@Annabelle Definitely don't use Qt Creator. If your screen reader doesn't support it that will just make things a lot harder.

I have written Qt apps for about 16 years and never used Qt Creator. You definitely don't need it.

As for what you need.. You said you need to be able to compile on the command line. Doing this is quite easy with Qt. First answer a couple questions for me and I can give you a complete step by step on how to get a program building. Once you can build a simple program, then you can worry about what goes into it like wizards and such.

What operating system are you using?
What compiler are you using? If windows is it visual studio or mingw? If linux it will probably be gcc, and if osx it will probably be clang. So mostly I just need to know in case of using windows.

@mrdebug We're all helping because it is very inspiring to see someone who is blind trying to learn and do something so sight oriented. The challenge she faces seems almost insurmountable to me. I am willing to help everyone on these forums but some people just deserve that extra attention. :)

I think the compiler I have is Mingw.
On one machine, I have Windows XP 32 Bit (I haven't upgraded that machine to Windows 7 64 Bit, as it would be $787 for a whole new machine, money I don't have right now.) On the machine on which I'm making my program's code, I have Windows 7 64 Bit.

ambershark

Ok so for mingw/windows you will need to open a command prompt, press window+r and type cmd then press enter.

Once in the command prompt cd to your code directory.

Then, if you do not have a project file, *.pro, you can create one with qmake -project. This will create a <name of your directory>.pro file for you.

You can then edit that file to include other sources and add QT options and CONFIG options.

Then just run qmake and then finally mingw32-make to build your project.

You will need to make sure that your environment path has the path to qmake and mingw32-make. I prefer to use an msys environment for my qmake/make since I'm a linux user and it is bash like. That's probably a bit much for first time though, so stick with the command prompt for now.

Additionally to what @ambershark said,
You should between the step qmake -project and qmake change your directory to a so called Shadow-Build Folder otherwise the commands qmake and make will create a big mess in your project folder.
They will automatically create a whole lot of files and directories, that are not neccessary for your creation of the app, but the compiler will need those.

"Shadow Build folders"? What are those?

SGaist

It's a folder outside of the sources of your application, usually at the same level:

--Code
----MyCoolProject
----build-mycoolproject
