Font size of Xterm output when running console application?

[cacb]

When you run a console application from the Code::Blocks IDE, you get an Xterm under Ubuntu 20.04. By default, the font size in this terminal window is extremely small. Is there a way to control that from a C::B setting? If not, is there some other way?

Edit: To see actual size of attachment font, it looks like the file must be downloaded

or switch to use the gnome-terminal.

Thanks for the quick and helpful reply...

It turns out it was much easier than I thought. Since I use KDE, there is an option to simply use konsole, the standard KDE terminal from Code::Blocks. Then I get my default font settings for that.  All is good, thanks again.

We have to do something more clever about this, but I'm not totally sure what and I don't have much time to experiment at the moment.
Probably some kind of auto-detect dialog would be a good idea or a detection scheme which tries to run them one by one using some hard-coded priority.

Also, there are these two, but I cannot spend time on them at the moment, but are important:

https://sourceforge.net/p/codeblocks/tickets/1005/

Can you try the patch from 1005 and tell me if it works for you? It would be helpful give that you don't use the ubuntu defaults of gnome+gnome-terminal.

Not sure how to apply a patch and it would take me time to figure out, and I don't have the time now.

BUT: why not leave the problem to the operating system and/or desktop environment? Maybe, instead of C::B calling a specific xterm, konsole, gnome-terminal or whatever, would it perhaps be a smarter solution if C::B called on x-terminal-emulator instead, and let the OS start the correct terminal emulator pre-configured by the desktop, or even reconfigured by the user?

Code Select Expand

which x-terminal-emulator
/usr/bin/x-terminal-emulator

If I start x-terminal-emulator from the KDE menu search field, I get an instance of konsole because on my system x-terminal-emulator maps to konsole:

Code Select Expand

sudo update-alternatives --config x-terminal-emulator

There are 5 choices for the alternative x-terminal-emulator (providing /usr/bin/x-terminal-emulator).

  Selection    Path                 Priority   Status
------------------------------------------------------------
* 0            /usr/bin/konsole      40        auto mode
  1            /usr/bin/koi8rxterm   20        manual mode
  2            /usr/bin/konsole      40        manual mode
  3            /usr/bin/lxterm       30        manual mode
  4            /usr/bin/uxterm       20        manual mode
  5            /usr/bin/xterm        20        manual mode

Press <enter> to keep the current choice[*], or type selection number:

So I am guessing that under Gnome, x-terminal-emulator maps to gnome-terminal? If that is so, would it not be a much simpler and generic solution under linux if C::B used x-terminal-emulator for console output? If correct, C::B terminal output would seamlessly adapt to the current environment.

1. This is what the patch in 1005 does
2. This is debian/ubuntu specific. I don't have x-terminal-emulator on my gentoo. I don't think this is available on redhat based distros as well.
