No no.. it's perfect!
I'm studing c++ and i don't know the try statement yet (this is why i
didn't think on it.
The program now works:
#include <++dfb.h>
#include <iostream>
using namespace std;
int main()
{
//here we declare the main interfaces
IDirectFB dfb;
IDirectFBInputDevice keyboard;
IDirectFBEventBuffer keybuffer;
DFBInputEvent keyevent;
//start directfb
DirectFB::Init();
dfb = DirectFB::Create();
//set up a keyboard
keyboard = dfb.GetInputDevice(DIDID_KEYBOARD);
//set up a keybuffer
keybuffer = keyboard.CreateEventBuffer();
while(1) //we start the main cicle, an infinite one
{
try
{
keybuffer.WaitForEventWithTimeout(2,0); //let us listen if a
key is pressed
}
catch (DFBException *ex) {} //if we get no event we do nothing
while(keybuffer.GetEvent(DFB_EVENT(&keyevent))) //if there is a
event...
{
if (keyevent.type == DIET_KEYPRESS) //and this event is a
key pressed
{
if(keyevent.key_id == DIKI_ESCAPE || keyevent.key_id ==
DIKI_F2) //and it's hte ESC or F2 button
return 1;
}
}
}
}
Thanks again :D
