我想动态的加listbox的item，现在是添加可以，但退出程序就出错了，为何

[zorro0799]

const TInt KNumberOfIcons_1(1);

TBool CDynamicListContainer::AddOneItem(TText* szText, int inIconName, int aBitmapId, int aMaskId)
{
if (iSavedGamesListBox != NULL)
{
CTextListBoxModel* model = iSavedGamesListBox->Model(); // not taking ownership
CDesCArray* savedGamesArray = STATIC_CAST(CDesCArray*, model->ItemTextArray());

TBuf<256> ibuf;
ibuf = (const TText* )szText;
savedGamesArray->AppendL(ibuf);

//icon
HBufC* iconFileName;
iconFileName = StringLoader::LoadLC(inIconName); // Pushes iconFileName onto the Cleanup Stack.
// Create an array of icons, reading them from the file
CArrayPtr<CGulIcon>* icons = new(ELeave) CAknIconArray(KNumberOfIcons_1);
CleanupStack::PushL(icons);
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, aBitmapId, aMaskId));
// icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmDynamiclist2player, EMbmDynamiclist2player_mask));
CleanupStack::Pop(icons);
CleanupStack::PopAndDestroy(iconFileName);

iSavedGamesListBox->ItemDrawer()->ColumnData()->SetIconArray(icons); // passing ownership of icons
iSavedGamesListBox->HandleItemAdditionL();
return TRUE;
}
return FALSE;

}

帮帮忙

为什么那么着急呢？我正调着呢就看见有贴子发出来了。你说我该回mail还是回贴子:)

如果中间不用换图标，把下面这段注掉就可以了：
/*
//icon
HBufC* iconFileName;
iconFileName = StringLoader::LoadLC(inIconName); // Pushes iconFileName onto the Cleanup Stack.
// Create an array of icons, reading them from the file
CArrayPtr<CGulIcon>* icons = new(ELeave) CAknIconArray(KNumberOfIcons_1);
CleanupStack::PushL(icons);
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, aBitmapId, aMaskId));
// icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmDynamiclist2player, EMbmDynamiclist2player_mask));
CleanupStack::Pop(icons);
CleanupStack::PopAndDestroy(iconFileName);
iSavedGamesListBox->ItemDrawer()->ColumnData()->SetIconArray(icons); // passing ownership of icons
*/

既然在这儿回了，这个问题我就不回mail了。

AddOneItem((TUint16*)L"0\t12345678", R_ICON_FILE_NAME,
EMbmDynamiclist1player, EMbmDynamiclist1player_mask);
AddOneItem((TUint16*)L"0\tabcdefg", R_ICON_FILE_NAME,
EMbmDynamiclist2player, EMbmDynamiclist2player_mask);
呵呵，谢谢，我其实是想不同的item不同的图标，我就把所有的图标放到一个mbm中，每次加时只是后面的两个参数不同，我以为这样就可，可发现不行，而且我不太理解以下两句话
CArrayPtr<CGulIcon>* icons = new(ELeave) CAknIconArray(KNumberOfIcons_1);//例子里
KNumberofIcons = 2;,我这里改成1了，
iSavedGamesListBox->ItemDrawer()->ColumnData()->SetIconArray(icons); //这里的icon数组是什么意思，一个item不是只有一个icon吗，如果上面的knumberoficon = 10;对应10个item？

我想你的理解有偏差。

　　CAknIconArray是动态数组，构造时的的参数是指这个数组的粒度，即初始元素个数以及以后每次动态增长的元素个数。

　　格式串时'\t'前的数字指图标在CAknIconArray数组中的下标。如果图标的个数是固定的，则你可以在构造时把它们都加载到CAknIconArray对象中，添加格式串时只要指定不同的数字就能显示不同的图标。
