Hi,
I develope the LPT_Interface.app and the gsmarkup file for the app
window is ready.
Now I want to give actions to buttons but don't know how to implement
these actions into the applicaton?
Say, the button is toggle type and it should to set, or reset a bit in
the parallel Data port.
To write to the Data port bit the code is in C:
---*
#include
#include
#include
#define base 0x378 /* printer port base address */
#define value 1 /* numeric value to send to printer port */
main(int argc, char **argv)
{
if (-1 == ioperm(base,1,1))
fprintf(stderr, "Couldn't get the port at %x\n", base), exit(1);
outb(value, base);
}
---*
and this must run with root privileges.
How can I implement this code in to the application?
Because the button is toggle type I must to write the code so so when
the button has title="1" then the action code must to write logical 1 to
the Data Port bit, but when the button title="0" then it must to write
logical 0 to the bit.
Is it good to write this code in main.m file?
Also, how can I achieve that that the Error messages appeares in the
label text which id="StatLine"?
Any advices will be appreciated!
