FUNCTION: AEEClsCreateInstance
DESCRIPTION
This function is invoked while the app is being loaded. All Modules must provide this
function. Ensure to retain the same name and parameters for this function.
In here, the module must verify the ClassID and then invoke the AEEApplet_New() function
that has been provided in AEEAppGen.c.
After invoking AEEApplet_New(), this function can do app specific initialization. In this
example, a generic structure is provided so that app developers need not change app specific
initialization section every time except for a call to IDisplay_InitAppData().
This is done as follows: InitAppData() is called to initialize AppletData
instance. It is app developers responsibility to fill-in app data initialization
code of InitAppData(). App developer is also responsible to release memory
allocated for data contained in AppletData -- this can be done in
IDisplay_FreeAppData().
PROTOTYPE:
int AEEClsCreateInstance(AEECLSID ClsId,IShell * pIShell,IModule * po,void ** ppObj)
PARAMETERS:
clsID: [in]: Specifies the ClassID of the applet which is being loaded
pIShell: [in]: Contains pointer to the IShell object.
pIModule: pin]: Contains pointer to the IModule object to the current module to which
this app belongs
ppObj: [out]: On return, *ppObj must point to a valid IApplet structure. Allocation
of memory for this structure and initializing the base data members is done by AEEApplet_New().
DEPENDENCIES
none
RETURN VALUE
AEE_SUCCESS: If the app needs to be loaded and if AEEApplet_New() invocation was
successful
EFAILED: If the app does not need to be loaded or if errors occurred in
AEEApplet_New(). If this function returns FALSE, the app will not be loaded.
SIDE EFFECTS
none

FUNCTION SampleAppWizard_HandleEvent
DESCRIPTION
This is the EventHandler for this app. All events to this app are handled in this
function. All APPs must supply an Event Handler.
PROTOTYPE:
boolean SampleAppWizard_HandleEvent(IApplet * pi, AEEEvent eCode, uint16 wParam, uint32 dwParam)
PARAMETERS:
pi: Pointer to the AEEApplet structure. This structure contains information specific
to this applet. It was initialized during the AEEClsCreateInstance() function.
ecode: Specifies the Event sent to this applet
wParam, dwParam: Event specific data.
DEPENDENCIES
none
RETURN VALUE
TRUE: If the app has processed the event
FALSE: If the app did not process the event

/*============================一下是对触摸事件的处理================================================*/
/*
开发建议
a. 因为快速包不允许修改程序，尽量使同一个程序可以在触摸屏事件定义不同的手机上都正常运行。例如利用配置文件。
case EVT_POINTER_DOWN:
case EVT_PEN_DOWN:
...处理...
break;
这种写法在某些新手机上可能会有问题。为保证兼容性，一次点击，在这些手 机上会同时发送POINTER,PEN这两种事件。会有重复处理的问题。
b. 低版本的触摸屏事件参数只包含位置信息。高版本的还包括是否双击这样的额外信息。如果需要使用这些信息，最好自己编写实现，避免高低版本处理不同。
c. 中断返回时很可能接受不到Up事件，要注意对这种情况的处理。
d. 如果是将非触摸屏版本改为触摸屏版本的话。可以考虑利用原先的按键处理程序，例如将触摸屏事件转换为相应的按键事件处理。
e. 即使不是开发触摸屏应用，也应在程序设计上有所考虑，方便以后扩充触摸屏功能。例如自己写控件上，即使现在只接受EVT_KEY,也应传入eCode。

/*
在手机处理触摸屏事件中 也有不同，已测试的手机情况如下：
----------------------------------------
LG KW838 ：
同时发送EVT_POINTER_XXXXX和EVT_PEN_XXXXX。
可能是这款手机速度太快，测试员感觉是一次的触摸，手机却总是会发送两次相同的事件。
Moto A1800 ：
发送EVT_PEN_XXXXX事件。
----------------------------------------
三星W599 ：
发送EVT_PEN_XXXXX事件，同时发送AVK_FUNCTION5按键事件。
输入法小键盘会被ITextCtl控件挡住。
屏幕边缘触摸坐标与显示坐标不一致，且偏离程度与高度有关。
---------------------------------------
三星W559 ：
发送EVT_PEN__W559_XXXXX事件，同时发送AVK_STOP按键事件。
输入法小键盘会被ITextCtl控件挡住。
测试员传送EVT_PEN_W559_XXXXX事件给BREW控件。但除了输入法小键盘外，其余控件均不响应。
显示坐标与触摸感应坐标不一致
x(显示)=x(触摸)
y(显示)≈y(触摸) – 24
---------------------------------------
Coolpad C528 ：
发送EVT_PEN_XXXXX事件
IhtmlViewer控件不支持触摸屏操作。
大显C8100 ：
发送EVT_PEN_XXXXX事件
没有EVT_PEN_MOVE事件
-------------------------------------
海信D90 :
同时发送EVT_POINTER_XXXXX和EVT_PEN_XXXXX事件。
但控件只处理EVT_PEN_XXXXXX事件。
软键盘会出现在屏幕下方。ITextCtl要覆盖到这个区域，软键盘才会相应。（不十分确定）。
----------------------------------------
UT CD500 :
同时发送EVT_POINTER_XXXXX和EVT_PEN_XXXXX事件。
但控件只处理EVT_POINTER_XXXXXX事件。
阿尔卡特OT-S659 :
同时发送EVT_POINTER_XXXXX和EVT_PEN_XXXXX事件。
但控件只处理EVT_POINTER_XXXXXX事件。
============================================
3、 3.1.5模拟器注意事项
目录或文件不要用中文名，全部小写。
注意大小限制。Mif和模拟器使用的device都有关于文件大小的限制。
数据库格式格式与2.X不同。（不确定）
当触摸点从屏幕边缘划出屏幕外时，模拟器不会发出Up事件。而在有些真机上是会发出的。
