    @Annabelle You can just leave Qt Creator, it won't hurt to have it on there and you'll only save a bit of hard drive space not having it there.

    If you can't get just a mingw install with Qt, then you can always install mingw by itself. I would be careful to get the exact version used to compile whatever version of Qt you are using though, just to avoid issues.

    Here's a link to mingw:
    https://sourceforge.net/projects/mingw/files/

    Keep in mind installing it this way can be kind of complicated compared to just letting Qt's installer do it for you, but it works. I've used the mingw direct version for years.

    Is the coding for all the Qt widgets and parameters like buttons and checkboxes different from version to version (for example, 4.8 vs. 5.9)? I'm confused on that one!

      @Annabelle Qt 4 to 5 would be different. Not hugely so, but definitely has some differences. 4 and 5 are not compatible at all.

      However versions during the same major version of Qt tend to be the same. Some things may get deprecated and some things may get added to the interface, but the core stuff stays the same. Your applications should always compile with newer Qt versions with the same major version number.

        I went to the link you provided and got the latest version of mingw-get-setup.exe, however, when I open it, it takes me to an installation manager. Is that what's supposed to happen? Also, for some reason, I have to be connected to the Internet when opening the file. When I try the command line prompt "mingw-get --help", I get the following error. "mingw-get is not an operable program or recognized command". That's a bit strange, since the installation manager specifically asks me to enter that command to have access to its help file.

          @Annabelle I haven't installed mingw in a long time so I'll let someone else help with the specifics of that. I'm not really a windows guy. I do almost exclusively posix oses like linux or mac.

          As for the error you got, that is because you are not in the directory with the mingw-get executable. That is a generic dos error that is telling you it has no idea what mingw-get is.

            When I installed the Mingw-Get-Setup.exe file, it put some sort of Installation Manager on my computer, and I'm not sure what that does. Also, I'm still wondering how to put together the commands to compile a simple example of a program after wrtiing the code in Notepad++. I know one of you fellow members said something about "using ID's", and I'm not exactly sure what that means.

              @Annabelle You can compile using cmake or qmake on the command line. It was covered above on how to do it by me and a few others.

                @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.

                Would the header files be created in Notepad++ as well? So I'm guessing that the codes I write would be saved as .cpp files?

                  Read that post again. I explicitly say that the project file should be a. pro extension not a cpp file. You can write it in notepad++ that's fine.

                  All the help you need has been clearly outlined in earlier posts by various people. Make sure you read them carefully and understand.

                    She seems to be wanted to be spoon feed all the answers versus looking and learning her answers. Jaws is more than capable of reading internet pages. She really needs to learn the basics before she can jump into QT.

                    Use Cmake or Qmake on the command line.

                    Use notepad++ to do all your .cpp and .h coding

                    Me if i was blind and in your shoes i would use visual studio 2013 with jaws and learn all about how it works (google)

                      Do you have the code ready, with a .pro file (it is a project definition file that Qt uses to compile applications)? If yes, then you can compile your project from the command line. Open cmd.exe (I guess you are on Windows operating system) and type:

                      qmake yourprojectname.pro
                      make
                      

                      That should be enough, assuming your environment is prepared (qmake and compiler are both set up in PATH system variable).

                      As a side note, as far as I know there is an accessibility team working at Qt Company, I'm sure they will be happy to hear how both Qt and Qt Creator can be improved to help blind people. You can try reaching them at qt-creator@qt-project.org. You can also subscribe to Qt Creator mailing list here: http://lists.qt-project.org/mailman/listinfo/qt-creator.

                      I tried typing the code qmake ceremonyscriptgenerator.pro
                      make
                      into the command prompt (cmd.exe), but I get the following error.
                      "qmake" is not a valid internal or external command or operable program.
                      Does anyone know why this error occurs? Do I have to have Qt Creator installed on my machine?

                        You don't need Qt Creator. Qt itself is enough, because qmake is part of it. If cmd complaints it can't find qmake it's probably because it is not in the PATH environment variable. I have not used Qt on Windows for a long time, but if nothing's hanged, you can probably run a Qt-provided command line which has the tools properly set up.

                        Alternatively, with your current command line, you can point it directly to where qmake is located, like this:

                        c:\path\to\where\qt\is\bin\qmake.exe file.pro
                        

                        Oh, right. Possibly you need to type in "qmake.exe" instead of just "qmake" on Windows.

                            @Annabelle No you will have to install Qt. You don't need to install the Creator part of Qt, but if you do it won't hurt. You can disable the install of Qt Creator as an advanced part of the install.

                              I tried that, but even the installer can't be fully accessed with JAWS or NVDA. Not even the built-in Microsoft Narrator that comes with Windows 7 can access that checkbox you're talking about. I've put in an Email message to the Qt Creator team, and unfortunately they haven't sent me an answer yet.

                                @tekojo maybe you can use your magic powers to ping people at Qt Company? See the post by @Annabelle above.

                                  I'm confused! Who's Tekojo?

                                      @Annabelle It won't hurt to just do the default install with Qt Creator. You'll still get Qt and the command line tools like Qmake using the default install. So I wouldn't worry about not being able to access that checkbox.

                                      Would be a nice thing to have fixed for the future though.

                                        @ambershark Is it possible we could write Morse code aka keyboard and just tab through the boxes on the installer and select what she needs by pressing keys?

                                          @Sunfluxgames You wouldn't really have to write anything.. someone could just run the installer and figure out the exact keypresses she needs to get to the box she wants to uncheck and then list them here. If she's careful she can do it without a screen reader.

                                          Also having a friend help install it would work too.

                                          But again, it's not necessary at all to uncheck qt creator. I usually let it install Qt Creator and I pretty much never use it. I can spare the 200mb or whatever it is on my hard drive though. :)
