页面菜单代码：
初始方法中添加的代码：
static boolean ET_InitAppData(hellobrew * pApp)
{
AEEDeviceInfo* pDeviceInfo;
if(!XMR_CreateMainControls(pApp))
return FALSE;
pDeviceInfo = (AEEDeviceInfo*) MALLOC( sizeof( AEEDeviceInfo ) );

pApp->m_rScreenRect.dx = pDeviceInfo->cxScreen;
pApp->m_rScreenRect.dy = pDeviceInfo->cyScreen - 16;

}
上面方法中新添加的代码是：

return FALSE;
在进入菜单页面时，先重置页面：

{
// Reset Menu Controls
IMENUCTL_Reset(pApp->m_pMenu);
}
{
// Reset Menu Controls
IMENUCTL_Reset(pApp->m_pMenu);

ET_Reset(pApp, TRUE);
// main menu
IMENUCTL_SetTitle( pApp->m_pMenu, EXPENSETRACKER_RES_FILE, IDS_MAIN_MENU, NULL);

pApp->m_eAppState = APP_STATE_MAIN;
}
static boolean XMR_CreateMainControls(hellobrew* pApp)
{
AEERect rc;
AEEItemStyle rNormalStyle;
AEEItemStyle rSelStyle;
// Create the main application controls.
if((ISHELL_CreateInstance(pApp->a.m_pIShell, AEECLSID_MENUCTL, (void**)(&pApp->m_pMenu)) != SUCCESS) ||

return FALSE;
// Let's reset text control size so on subsequent this won't misbehave by erasing screen
SETAEERECT(&rc, 0, 0, 0, 0);

rSelStyle.roImage = AEE_RO_TRANSPARENT;
IMENUCTL_SetStyle( pApp->m_pMenu, &rNormalStyle, &rSelStyle );
return TRUE;
}
4:添加Add New菜单的响应事件：
首先是在hellobrew_HandleEvent方法中添加代码：
if (IMENUCTL_HandleEvent(pMe->m_pMenu, eCode, wParam, dwParam))
return TRUE;
return TRUE;
然后在hellobrew_HandleEvent方法中添加代码：
// 判断是不是选择了添加菜单
case EVT_COMMAND: // Handle 'SELECT' button events
switch(wParam)
{
case IDC_ADD_NEW: // User selected 'Add New' from the Main Menu
pMe->m_eAppState = APP_STATE_ADD;
XMR_DisplayAddScreen(pMe);
return TRUE;
}
case EVT_COMMAND: // Handle 'SELECT' button events
switch(wParam)
{
case IDC_ADD_NEW: // User selected 'Add New' from the Main Menu
pMe->m_eAppState = APP_STATE_ADD;
XMR_DisplayAddScreen(pMe);
return TRUE;
}
用于调用XMR_DisplayAddScreen方法来画该功能中的画面。
case EVT_COMMAND:响应OK键按下的代码。
5：实现根据上下按钮选择菜单的功能：
在hellobrew_HandleEvent方法中添加代码：
case EVT_CTL_SEL_CHANGED:
// If the expense list screen is showing and the user changes the selected
// expense item in the menu control, get the description of the transaction
// from the database and display it at the top of the screen.
if (pMe->m_eAppState == APP_STATE_VIEW_LIST)
{
AECHAR psTitle[ MAX_DESC_SIZE + 1 ];
IMenuCtl * pMenu = (IMenuCtl*)dwParam;
uint16 nRecordID = IMENUCTL_GetSel(pMenu) - EXPENSE_LIST_ID;
XMR_GetExpenseItem( pMe, nRecordID, NULL, psTitle, NULL, NULL );
IMENUCTL_SetTitle(pMenu, NULL, NULL, psTitle);
IMENUCTL_Redraw(pMenu);
return TRUE;
}
break;
// If the expense list screen is showing and the user changes the selected
// expense item in the menu control, get the description of the transaction
// from the database and display it at the top of the screen.
if (pMe->m_eAppState == APP_STATE_VIEW_LIST)
{
AECHAR psTitle[ MAX_DESC_SIZE + 1 ];
IMenuCtl * pMenu = (IMenuCtl*)dwParam;
uint16 nRecordID = IMENUCTL_GetSel(pMenu) - EXPENSE_LIST_ID;
XMR_GetExpenseItem( pMe, nRecordID, NULL, psTitle, NULL, NULL );
IMENUCTL_SetTitle(pMenu, NULL, NULL, psTitle);
IMENUCTL_Redraw(pMenu);
return TRUE;
}
break;
代码中调用了XMR_GetExpenseItem方法，添加XMR_GetExpenseItem方法：
extern boolean XMR_GetExpenseItem( hellobrew* pApp, uint16 nRecordID, dword* pnDateTime, AECHAR* psDesc, unsigned char* pcType, dword* pnAmount )
{
IDBRecord* pRecord;
// Get the record using the ID
if(( pRecord = IDATABASE_GetRecordByID( pApp->m_pDatabase, nRecordID )) == NULL)
return FALSE;
// Extract each of the data values from the record and assogn to the output
// arguments
XMR_ParseExpenseRecord( pRecord, pnDateTime, pcType, psDesc, pnAmount );
// Release the record
IDBRECORD_Release( pRecord );
return TRUE;
}
{
IDBRecord* pRecord;
// Get the record using the ID
if(( pRecord = IDATABASE_GetRecordByID( pApp->m_pDatabase, nRecordID )) == NULL)
return FALSE;
// Extract each of the data values from the record and assogn to the output
// arguments
XMR_ParseExpenseRecord( pRecord, pnDateTime, pcType, psDesc, pnAmount );
// Release the record
IDBRECORD_Release( pRecord );
return TRUE;
}
因为有pApp->m_pDatabase的调用，所以需要在_hellobrew结构体中添加变量：
IDatabase* m_pDatabase;
IDatabase类型存在文件AEEDB.h。
在XMR_GetExpenseItem方法中调用了XMR_ParseExpenseRecord方法。
XMR_ParseExpenseRecord代码：
static boolean XMR_ParseExpenseRecord( IDBRecord* pRecord, dword* pnDateTime, unsigned char* pcType, AECHAR* psDesc, dword* pnAmount )
{
uint16 nFieldLen;
AEEDBFieldName rFieldName;
AEEDBFieldType rFieldType;
AECHAR* psStringPtr;
IDBRECORD_Reset( pRecord ); // Set the record index to -1
// Get the first field
rFieldType = IDBRECORD_NextField( pRecord, &rFieldName, &nFieldLen );
// Set the DateTime if pnDateTime is a valid pointer
if( pnDateTime )
IDBRECORD_GetFieldDWord( pRecord, pnDateTime );
// Get next field
rFieldType = IDBRECORD_NextField( pRecord, &rFieldName, &nFieldLen );
// Set the description if psDesc is a valid pointer
if( psDesc )
{
psStringPtr = IDBRECORD_GetFieldString( pRecord );
WSTRCPY( psDesc, psStringPtr );
