Key Code Finder

Post by arras »

Just press keyboard key to find out its EKEY_CODE representation.
To my surprise, not all keys are represented by enumeration names. ~ / ; ' [ ] are not for example, but they are detected and given index numbers.

Code: Select all

// Key Code Finder for Irrlicht 1.4
// by arras
// 08.02.2008

// press keyboard key to find its EKEY_CODE index and name

#include <irrlicht.h>
using namespace irr;

u32 Index;
gui::IGUIStaticText *Text1;
gui::IGUIStaticText *Text2;

core::stringc KeyCodeName[KEY_KEY_CODES_COUNT];

class EventReceiver : public IEventReceiver
{
public:
   virtual bool OnEvent(const SEvent& event)
   {
      if (event.EventType == EET_KEY_INPUT_EVENT)
      {
         if(event.KeyInput.PressedDown)
         {
            Index = (u32)event.KeyInput.Key;
            core::stringw tmp("ENUMERATION INDEX = ");
            tmp += Index;
            Text1->setText(tmp.c_str());
            
            tmp = "EKEY_CODE = ";
            tmp += KeyCodeName[Index].c_str();
            Text2->setText(tmp.c_str());

Hmm, for some optimizations you might want to take the declarations for KeyCodeName out of the main() functions, and opt for a more appropiate decision of declaring it as 'const'. Otherwise, great code.

Thanks Halifax.

but how can I do that with core::string object?

I don't know about stringc, as I don't use it much, but I would try this:

Code: Select all

const core::stringc* KeyCodeNames = { "ONE_NAME", "TWO_NAME", etc... }
but if that doesn't work, then you can always switch over to 'char'

Code: Select all

const char** KeyCodeNames = { "ONE_NAME", "TWO_NAME", etc... }
And all in all optimization isn't exactly important for this project, but it is just a suggestion in the future for your other projects that may need memory optimization, because those values should definitely be read-only and not read-write.

Thanks Halifax.
Problem is not all "slots" in array are used. This way it was easier and quicker to copy/paste all names/numbers from Keycodes.h without mistakes (hopefully) ...and it took some time :wink:
But I'll keep your advice in mind for future.

Well even if not all slots are used, then you just insert an empty string "" for the empty slot.

Thats possible, but without that pointer.
