Qt Programming Language

@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?

[Allanis]

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)

@sierdzio said in Qt Programming Language:

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?

[sierdzio]

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.

I've searched in my computer's hard drive, and I can't find Qmake.exe, as it was uninstalled along with Qt Creator. Is there a way for me to find a direct download to just the Qmake.exe component? If so, where do I search?

[ambershark]

@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.

[sierdzio]

@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?

[SGaist]

He's the community manager but currently pretty busy with the Qt Contributor Summit as well as Qt World Summit.

[ambershark]

@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.

[Sunfluxgames]

@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?

[ambershark]

@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. :)

I've got Qt Creator on my machine, and unfortunately I'm not able to create widgets without a mouse. I wonder, are there any keyboard equivalents to mouse clicks for creating widgets and wizard pages?

[ambershark]

@Annabelle Absolutely.. I do all my widgets in code. I almost never use the designer to create my forms/widgets.

I.e. if you want a label and text entry field you could do:

QWidget *w = new QWidget();
w->resize(600,400);
QHBoxLayout *box = new QHBoxLayout();
box->addWidget(new QLabel("Name"));
box->addWidget(new QTextEdit());
w->setLayout(box);
w->show();

Do you have any remote access software where you could log on to my computer and show me what you mean? For example, ITeleport? By keyboard shortcuts, I mean something like:
"Create New Widget" (Alt+W)
"Set Layout" (Control+Shift+L)
"Add Widget" (Alt+A)
"Show/Hide" (Control+Shift+H)
"Resize" (Control+R)

[Sunfluxgames]

@Annabelle You wouldn't need shortcuts to create anything.

In notepad++ you would create a class that can create dynamic widgets with you passing arguments for size and name in the function. All the designer lets us do is make it easier to drag and drop widgets into place while building code for us.

In your case you going to build your application through C++ and .h files.

I'm still a bit confused, because I want to try the Qt Designer, but I seem to be left in the dust as to how I would have access to the command to create, add, delete, and show/hide widgets without keyboard shortcuts. Since I have 0% vision, this is why I use a screenreader and keyboard shortcuts. I wonder if any of the Qt Creator administrators could help with making the program more screenreader friendly. Image-based icons are a screenreader's weak point. text-based icons and menus with detailed descriptions are what is accessible to both sighted and blind individuals alike.
