Yeah, I would put it in the OgreBindings logic.

I was mainly curious if Noesis already had that array defined so that I could paste it into my version of the bindings as a hot-fix (as opposed to me writing it by hand). If you don't already have it written though I can wait until the update goes out. :)
That array is not defined anywhere because it has to map from Ogre key definitions to NoesisGUI key definitions. Our keys are defined in NsGui/InputEnums.h
Code: Select all
enum Key
{
    Key_None,
    Key_Back,
    Key_Tab,
    Key_Clear,
    Key_Return,
    Key_Pause,

    Key_Shift,
    Key_Control,
    Key_Alt,

    Key_Escape,

    Key_Space,
    Key_Prior,
    Key_Next,
    Key_End,
    Key_Home,
    Key_Left,
    Key_Up,
    Key_Right,
    Key_Down,
    Key_Select,
    Key_Print,
    Key_Execute,
    Key_SnapShot,
    Key_Insert,
    Key_Delete,
    Key_Help,

    Key_0,
    Key_1,
    Key_2,
    Key_3,
    Key_4,
    Key_5,
    Key_6,
    Key_7,
    Key_8,
    Key_9,

    Key_Pad0,
    Key_Pad1,
    Key_Pad2,
    Key_Pad3,
    Key_Pad4,
    Key_Pad5,
    Key_Pad6,
    Key_Pad7,
    Key_Pad8,
    Key_Pad9,

    Key_Multiply,
    Key_Add,
    Key_Separator,
    Key_Subtract,
    Key_Decimal,
    Key_Divide,

    Key_A,
    Key_B,
    Key_C,
    Key_D,
    Key_E,
    Key_F,
    Key_G,
    Key_H,
    Key_I,
    Key_J,
    Key_K,
    Key_L,
    Key_M,
    Key_N,
    Key_O,
    Key_P,
    Key_Q,
    Key_R,
    Key_S,
    Key_T,
    Key_U,
    Key_V,
    Key_W,
    Key_X,
    Key_Y,
    Key_Z,

    Key_F1,
    Key_F2,
    Key_F3,
    Key_F4,
    Key_F5,
    Key_F6,
    Key_F7,
    Key_F8,
    Key_F9,
    Key_F10,
    Key_F11,
    Key_F12,
    Key_F13,
    Key_F14,
    Key_F15,
    Key_F16,
    Key_F17,
    Key_F18,
    Key_F19,
    Key_F20,
    Key_F21,
    Key_F22,
    Key_F23,
    Key_F24,

    Key_NumLock,
    Key_Scroll,

    Key_Count // for static array dimension
};
A static array must be defined somewhere with a table that translate from Ogre to NoesisGUI. It is an easy task. I was going to do it but I am not sure if the encapsulation we have in Ogre bindings is correct.

This function for example,
Code: Select all
extern "C" NS_DLL_EXPORT void Noesis_KeyDown(void* uiRenderer, int key)
shouldn't Ogre bindings manage the key translation automatically for the user? It is strange to me that an user of the bindings have to translate inputs from ogre to noesis. I think that Ogre should have an internal list of created NoesisGUI renderers and automatically send keys to them.

I don't know much about Ogre. In fact, the initial version of the bindings was done by the Ogre team. But I wonder if this could be improved.

What do you think?

The conversion should definitely happen withing the Bindings, since that code is meant to join the two systems. I've implemented a mapping on my end. Keep in mind though that I have included the bindings code directly in my project and removed the dll logic. At the top if my cpp file I have:
Code: Select all
static Noesis::Gui::Key s_OISKeyMappings[] =

	Key_None		//KC_MEDIASELECT = 0xED     // Media Select
};
This maps the OIS codes to the Noesis codes. The comments are taken from the OIS code and I have marked gaps. Note that OIS supports many more inputs than Noesis does so I have mapped those to Key_None. There are also some values in the Noesis enumeration that I was uncertain what they corresponded to. Furthermore OIS separates out things like left control and right control whereas Noesis does not so I mapped both to the same Noesis command (I am not sure if that will cause issues if a user uses both left and right keys at the same time). If you plan on integrating something like what I have pasted above it could definitely use a second set of eyes as I have barely tested it.

In my Noesis_KeyUp and Noesis_KeyDown methods I simply map by doing the following:
Code: Select all
Key nsKey = s_OISKeyMappings[key];

Hi,

Excellent work! I see that there are more codes in OIS but many of them were intentionally omitted in Noesis. For example KC_LBRACKET and KC_RBRACKET don't correspond to a physical key in a Spanish Keyboard. We tried to avoid those conflicting keys. Although may be we should extend our enumeration like that. Anyway these keys are used for inputs that do not require translation. For text input, we have a another function in our renderer that receive already translated characters in UTF8 :
Code: Select all
/// Notifies Renderer that a key was translated to the corresponding character
virtual void Char(NsUInt32 ch) = 0;
This is the function that feeds things like the textbox.

As I told I think that the current abstraction of the bindings is not correct. Anyway I will update the github repository as soon as possible. Could you send me your implementation to use as reference?
