Hi Mirek,
Sorry about virtual functions. Maybe we can remove some.
Please also consider the X11 implementations

Here my codes for X11:
at CtrlCore.cpp

#ifdef PLATFORM_X11
	static int ImePreEditStartCB(XIC xic, XPointer clientData, XPointer callData);
	static void ImePreEditDoneCB(XIC xic, XPointer clientData, XPointer callData);
	static void ImePreEditDrawCB(XIC xic, XPointer clientData, XIMPreeditDrawCallbackStruct *callData);
	static void ImePreEditCaretCB(XIC xic, XPointer clientData, XIMPreeditCaretCallbackStruct *callData);
	#endif

at Ctrl.cpp

#ifdef PLATFORM_X11
int Ctrl::ImePreEditStartCB(XIC xic, XPointer clientData, XPointer callData)
{
	Ctrl *ctrl = (Ctrl*)clientData;
	
	Ptr<Ctrl> pfocusCtrl = ctrl->GetFocusCtrl();
	if(!pfocusCtrl)
		return -1;
	
	pfocusCtrl->ImePreEditStart();
	return -1;
}

void Ctrl::ImePreEditDoneCB(XIC xic, XPointer clientData, XPointer callData)
{
	Ctrl *ctrl = (Ctrl*)clientData;
	
	Ptr<Ctrl> pfocusCtrl = ctrl->GetFocusCtrl();
	if(!pfocusCtrl)
		return;
	pfocusCtrl->ImePreEditEnd();
}

void Ctrl::ImePreEditDrawCB(XIC xic, XPointer clientData, XIMPreeditDrawCallbackStruct *callData)
{
	Ctrl *ctrl = (Ctrl*)clientData;
	Ptr<Ctrl> pfocusCtrl = ctrl->GetFocusCtrl();
		
	if(callData)
	{
		int caretPos = callData->caret;
		int changeFirst = callData->chg_first;
		int changeLength = callData->chg_length;
		
		if(callData->text)
		{
			int length = callData->text->length;

			if(!callData->text->encoding_is_wchar)
			{
				String newString = callData->text->string.multi_byte;
				WString newWString = ToUnicode(newString, newString.GetLength(), CHARSET_UTF8);
				
				pfocusCtrl->ImePreEditSetText(newWString);				
			}
		}
	}
}

void Ctrl::ImePreEditCaretCB(XIC xic, XPointer clientData, XIMPreeditCaretCallbackStruct *callData)
{
	Ctrl *ctrl = (Ctrl*)clientData;
	Ptr<Ctrl> pfocusCtrl = ctrl->GetFocusCtrl();
	
	if(!pfocusCtrl)
		return;
	
	pfocusCtrl->imePreEditCursor = callData->position;
	pfocusCtrl->ImePreEditSyncCaret();
	pfocusCtrl->SyncCaret(); 
}
