How to input the arrow keys when debugging

[falao84]

Hello everyone !
I have a C program to identify the keyboard input.
But when debugging, the debugger can not get input from the arrow keys.

CodeLite version : 5.4 (from the CodeLite apt repositories)
OS : debian wheezy
gcc version : 4.7.2
gdb version : 7.4.1

Here is a test source.

Code: Select all

#include <stdio.h>

int main(int argc, char **argv)
{
	int ch;
	while (1)
	{
		ch = getchar();
		printf("ch = %d\n" , ch);    // insert a breakpoint here!
		if (ch == 'q')
		{
			break;
		}
	}
	return 0;
}

I insert a breakpoint to watch the input value, but I cannot input the arrow keys when debugging.
thanks a lot for help.

Does it work without the debugger?

Yes. The test program will work well.
But It cannot get arrow key in debug model.

I would say that one terminal send special character for arrow key (something like ^[[A if I remember correctly).

Its probably a limitation with the current terminal emulator that codelite uses
Can you please file a bug report for this?

I have submitted a bug report, but I'm not familiar with the process and format.

I hope it can be improved.
