关于brew平台下email内容浏览支持长按键

[miaoyl]

email浏览正文时支持长按键，一下是三个函数，请哪位大师指点一下具体怎么实现 ，这个不知道是不是与滚动条关联起来的？

boolean IdleApp_OnKeyPress(CIdleApp* pMe, AEEEvent eCode, uint16 wParam, uint32 dwParam)
{
pMe->wLongPressedKey = 0;
switch (wParam)
{
case AVK_UP:
case AVK_DOWN:
pMe->wLongPressedKey = wParam;
ISHELL_SetTimer(pMe->pIShell, 1000, (PFNNOTIFY)IdleApp_OnLongPress, pMe);
break;

default:
break;
}
return TRUE;

}


boolean IdleApp_OnKeyRelease(CIdleApp* pMe, AEEEvent eCode, uint16 wParam, uint32 dwParam)
{
pMe->wPressedKey = 0;
ISHELL_CancelTimer(pMe->pIShell, (PFNNOTIFY)IdleApp_OnLongPress, pMe);

switch (wParam)
{
case AVK_UP:
//do AVK_UP pressed operation
//...
break;

case AVK_DOWN:
//do AVK_DOWN pressed operation
//...
break;

default:
break;
}
return TRUE;

}


boolean IdleApp_OnLongPress(CIdleApp* pMe)
{
switch(pMe->wLongPressedKey)
{
case AVK_UP:
//do AVK_UP pressed operation
//...
ISHELL_SetTimer(pMe->pIShell, 500, (PFNNOTIFY)IdleApp_OnLongPress, pMe);
break;

case AVK_DOWN:
//do AVK_DOWN pressed operation
//...
ISHELL_SetTimer(pMe->pIShell, 500, (PFNNOTIFY)IdleApp_OnLongPress, pMe);
break;

default:
break;
}
return TRUE;

}

滚动条代码如下

static __inline void EmailAFmMgr_Down_ScrollEvent(St_EmLAUIView *pMe)
{
if (pMe->G_iHeight > pMe->pStFmMgr->diDevice.cyScreen - WDG_SOFTKEY_HIGTH - WDG_TITLE_HIGTH)
{
if ((pMe->seEvent.position + UPDOWN_SCROLL_OFFSET > pMe->uiRecordTextPos) &&
pMe->seEvent.position < pMe->uiRecordTextPos)
{
pMe->G_wp.bVisible = TRUE;
pMe->G_wp.x = 0;
pMe->G_wp.y += -(pMe->uiRecordTextPos - pMe->seEvent.position);
pMe->seEvent.position += (pMe->uiRecordTextPos - pMe->seEvent.position);
pMe->G_iHeight -= (pMe->uiRecordTextPos - pMe->seEvent.position);
}

pMe->G_wp.x = 0;
pMe->G_wp.y += -UPDOWN_SCROLL_OFFSET;

}

IXYCONTAINER_SetPos(pMe->piXYContainer, WIDGET_ZNORMAL, WIDGET_ZNORMAL, &pMe->G_wp);

}

if (pMe->piScrollViewModel)

}
}
