Qt Programming Language

Here's a screenshot of yet another error. I'm not sure what I did wrong. I deleted the lines with pasted numbers, but even Visual Studio didn't like something I did then.

My screenreader can't tell if an underline has a color or is squigly. It can say _ (underline). Is that the mark you're talking about?

In your latest screenshot, there was a red squiggly line underneath "#include". Did your screenreader announce that? If not, don't worry -- the error is repeated under the Error List pane: "cannot open source Hello World! file "stdafx.h". Did your screenreader announce that?

@Annabelle said in Qt Programming Language:

Here's a screenshot of yet another error.

Change <stdafx.h> to "stdafx.h". In other words, change the angular brackets to double quotation marks.

It seems that when I type #include "stdafx.h", the quotation marks, for some reason, are automatically changed to angular brackets (<>). How do I prevent that from happening?

Annabelle

How's this?

This looks fault-free, and seems to have run without error! I don't know where the "Hello world" output went though? On that Output tab you have the Show output from combobox set to Debug, you may have to set that to something else to see/hear the program output?

How do I do that, I wonder? After I make the "Hello World" program, what do I do next?

@Annabelle
Ignore my comment about the Debug tab, I think. The question is: when you run the program, it should output Hello world!, where does that output go to? Does it maybe open a console window, send it there, and then close it as soon as your program finishes, all of which would be near "instantaneous"? It may depend on your project type, I don't know. You may need hep on this from VS C++ people here....

When you run your program (Ctrl + F5), a window should pop up and that window should contain the words "Hello world!". The window will close if you press any key while the window has focus.

Did JAWS read the contents of that window to you?

This is what the output window looks like in a screenshot. 0_1541609206448_6d656a50-ae21-4c35-b9e3-89f42a2c7ce5-image.png
What is the meaning of this message?
"The program '[2880] Hello World!.exe' has exited with code 0 (0x0)."

@Annabelle

"The program '[2880] Hello World!.exe' has exited with code 0 (0x0)."

It's just Visual Studio letting you know good news! It's telling you that you just ran your program executable (Hello World!.exe), it ran to completion and exited, and it returned an "exit code" of 0 (which is good, is what your code does, but which you don't care about).

My question still remains, however. When that program ran it sent the string Hello World! to its "output" (that's the purpose of this program). Where did that "output" go? (I don't use Visual Studio, and with your project type, so I don't know. @JKSH said earlier:

Did JAWS read the contents of that window to you?

So how does this behave for you? Did you get to hear about that output? Did you press a key to close a window which had opened?

I didn't hear about the output. When I pressed the shortcut to run the program, it first asked me if I wanted to build it, and I said "Yes". Then it launched the Command Prompt. What's up with that, I wonder?

It is probably in that Command Prompt window that I would expect the text of Hello World! to have been output. Is that possible?

JAWS doesn't show anything in the Command Prompt. If the text was shown, I'd be able to read it with the left and right arrow keys.

JonB

@Annabelle
At this point, wait for somebody helpful to try just what you have in Visual Studio and explain what it is they see about where the output goes.

This user (KrolPolski) found that arrow keys don't work in the Command Prompt for JAWS, but another user (Graham87) described a workaround: https://www.reddit.com/r/Blind/comments/8zf1f1/using_a_command_prompt_with_jaws/

See if you can get JAWS to read something on the Command Prompt before it closes. The Command Prompt should contain the text, "Hello world!"

If you still have no luck with JAWS, does the Microsoft Narrator work?

I ran it again, and in the Command Prompt, I got:
"Hello World! Press any key to continue..."
What do I do next?

JonB

@Annabelle

What do I do next?

Well, that's it for "Hello World": you've done it! (And very well done!) You have written a program, compiled it, and run it successfully with the expected output.

What you do now is up to you :) If you mean you want to turn to Qt you'd have to install it, I don't know what you intended to do.

I wonder if I could make Qt programs with Visual Studio. Or is that just for C++?

JonB

@Annabelle
You can integrate Visual Studio with Qt to develop programs, or you can use Qt Creator as your "IDE" (Integrated Development Environment). I don't know whether previous discussions have indicated a preference for which one for you.

I think from what I've experienced so far, Visual Studio is the more accessible one for me. That being said, how would I make Qt programs with Visual Studio?
