How to see output in a wxWidgets project?

[Otto]

Hi,

I would like to know how do I check what was printed with a std::cout in a GUI (wx) during development.
I can't find any output window/view.

I only see output if I run the app outside C::B via CLI.


Thanks.

Set the type of your project to console and it will show you the output

That didn't work. The output window appears, but nothing is printed.

I just tested it (on linux) and it works fine.

Hm, if you're on windows you should read here: http://msdn.microsoft.com/en-us/library/ms682073%28VS.85%29.aspx

You need AttachConsole + a way to redirect stdout/stdin to the console... let google be your friend...

Tested on Vista and it works out of the box.

I'm using Linux (Debian) and C::B 10.05.

I tested again and noticed it is only printed after I quit the program. I wasn't seeing because the output window is closed at that moment too. Have to keep "Pause when execution ends" checked.

Can't it be printed as soon as std::cout is called?

Tested again on linux (stepped through the code with debugger) and the output appears immediately after stepping over cout.

[Otto]

That's nice, but it doesn't work for me. Is there anything I can do?

Ps: you're testing in a GUI (configured later to console) app, right? The cout is called when I do a GUI action (Menu help > about).

Tested it and it works on Windows 6.1 AKA 7

Note: Flush was necessary to see output

Code Select Expand


std::cout << "Test Message" << std::flush;


Remember to change project properties for target to "Console Application" and checkmark "Pause when Execution Ends"

That was it! Thanks.

Sorry everyone, I'm new to C++.

[Jenna]

I used std::endl as last argument and that also seems to flush.

[Otto]

I confirm endl is enough.
