[Moved] QT and data input in ubuntu terminal
-
Sorry, the code was displayed wrong in the previous post:
@
#include <iostream>
using namespace std;
#include <cctype>int fuct (int);
int main()
{
int n;cout << "Input number: "; while (cin >> n) { int fk = fuct (n); cout << "\nFactorial: " << fk << "\n"; cout << "Input number: "; } return 0;
}
int fuct (int n)
{
if (n == 0) return 1;
else if (n == 1) return 1;
else return n * fuct(n-1);
}
@[EDIT: code formatting, Volker]

OK, thanks. I suppose that, given that Qt is a GUI development system, this is reasonable, though it may surprise some people who come from a more conventional IDE like Eclipse.
Is there at least a way to launch the terminal from Qt? Some minor level of integration would make it a little easier.
EDIT: let me rephrase that: there does appear to be some kind of terminal integration (though I can't get it to work for me); can one launch an app to terminal from Qt while still controlling the app through the Qt debugger? That would be slick.

It's not a problem of GUI or console development. You can have console input on a GUI program too :-)
Ah, seems that I was wrong!
In the run settings (project view of Creator) you can check a checkbox "run in terminal", this might be what you want. It's a bit cumbersome on the mac though (I remember you being on OS X, right?). You must set the terminal application on the mac to
/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal
(Settings, Environment, first tab)

There actually is a "launch in terminal" in the run settings of your project in Qt Creator... Go to project mode and visit the run settings there.

[quote author="mzimmers" date="1302358795"]That sure seems like it should work, doesn't it? But, when I try to start a debug session, I get an error message at launch, saying it can't start the terminal emulator '/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal'. Dunno...
[/quote]This should work. Where is your Terminal.app located? You'll need to enter
/path/to/Terminal.app/Contents/MacOS/Terminal
into the config field.
EDIT: You actually are on a Mac, aren't you?

For me it works, but the new terminal window is launched in the background. You have to select it via the dock or the running apps selector (cmd-tab). Also, the newly opened terminal is not quit once you terminate your application, you have to quit it manually (and watch out that you do not quit your regular terminal!)

Oho!
I just went back into preferences, and this time, I hit the apply button. This time the terminal launched. I had assumed just hitting "OK" would have done this for me.
Thanks for the help.
EDIT: just as an FYI for anyone reading this thread, note that while Terminal will launch your application, it will do so from the context of the default directory for your user account, NOT the directory that the application is in. You may need to move around data files or engage in directory processing within your program to achieve the desired results.

I seem to be having the opposite problem. My terminal window goes away, but according to the Application Output view, the app hasn't terminated yet. I hit the red square, and get a warning that the app is still running. Not a showstopper, but odd...
