Enable HGE to support Chinese (2)-HGE Chinese Input

 

Crazy and depressing ing...

I did not see any text when I wrote something yesterday...

It's a waste of time.

I have to do it again today... how does this CSDN work?

Forget it. Let's talk about how it works, typing tired...

Because the method I mentioned is to directly change the HGE kernel ..

So there are not many changes, but not a few lines of code ..

Steps:

1: Add a structure to hge. h to save our input data.

Struct hgeIMEEvent
{
Bool isIME;
Char value [3];
};

2: add an interface for retrieving input data in hge. h:

Virtual bool CALL Input_GetIMEEvent (hgeIMEEvent * ime) = 0;

3: Next we need a table to store the input data. We use the general HGE style and add the structure in hge_impl.h:

Struct CIMEEventList
{
HgeIMEEvent ime;
CIMEEventList * next;
};

4: complete the interface declaration. Add the interface in hge_impl.h:

Virtual bool CALL Input_GetIMEEvent (hgeIMEEvent * ime );

5: the data source and processing are added to hge_impl.h. All the real-time input data will be stored here for processing, but you will not be notified.

CIMEEventList * imeEvent;
Void _ BulidIMEEvent (char key [3], bool isIME );
Void _ ClearIMEEvent ();

6: complete the function bodies of the preceding interfaces. Add them to input. cpp.

(Welcome to repost: Original Author's BLOG (ShowLong ))

Void HGE_Impl: _ BulidIMEEvent (char key [3], bool isIME)
{
CIMEEventList * newEvent = new CIMEEventList; newEvent-> next = 0;
NewEvent-> ime. isIME = isIME;
If (isIME)
{
NewEvent-> ime. value [0] = key [0];
NewEvent-> ime. value [1] = key [1];
NewEvent-> ime. value [2] = '/0 ';
}
Else
{
NewEvent-> ime. value [0] = key [0];
NewEvent-> ime. value [1] = '/0 ';
NewEvent-> ime. value [2] = '/0 ';
} If (! ImeEvent)
ImeEvent = newEvent;
Else
{
CIMEEventList * last = imeEvent;
While (last-> next)
Last = last-> next;
Last-> next = newEvent;
}
} Bool HGE_Impl: Input_GetIMEEvent (hgeIMEEvent * ime)
{
CIMEEventList * eptr; if (imeEvent)
{
Eptr = imeEvent;
Memcpy (ime, & eptr-> ime, sizeof (hgeIMEEvent ));
ImeEvent = eptr-> next;
Delete eptr;
Return true;
} Return false;
} Void HGE_Impl: _ ClearIMEEvent ()
{
CIMEEventList * next, * ptr = imeEvent; while (ptr)
{
Next = ptr-> next;
Delete ptr;
Ptr = next;
}
ImeEvent = 0;
}

7: Find all the call _ ClearQueue (); and add the code below it:

_ ClearIMEEvent ();

8: In system. cpp, find the System_Start function body. The code to be replaced is started. below:

TranslateMessage (& msg );

9: do not forget to write the following sentence when constructing hge_impl:

ImeEvent = 0;

10: This is the key. With the above code, you can get the input.

Insert the code before the next case of case WM_SETCURSOR: in the main WindowProc function body:

Case WM_IME_CHAR:
{
Char imeChar [3];
ImeChar [0] = (char) (wparam> 8 );
ImeChar [1] = (char) wparam;
ImeChar [2] = '/0 ';
PHGE-> _ BulidIMEEvent (imeChar, true );
}
Break;
Case WM_CHAR:
{
If (wparam = VK_BACK |
Wparam = VK_TAB |
Wparam = VK_RETURN |
(Char) wparam <= 0)
Break; char imeChar [3];
ImeChar [0] = (char) wparam;
ImeChar [1] = '/0 ';
ImeChar [2] = '/0 ';
PHGE-> _ BulidIMEEvent (imeChar, false );
}
Break;

Now, all the code is added...

If you want to create a GUI to call it, try it.

Only three codes are required.

HgeIMEEvent imeEvent;
While (tKernelServer: Instance ()-> Device ()-> Input_GetIMEEvent (& imeEvent ))
{
AddChar (imeEvent. value, imeEvent. isIME );
}

It's easy enough. As for why imeEvent should be defined like this... I will not explain it here... if you don't think you need to change it.
