Display icons in Grid

[stephen-cheung]

Dear all,

I think I have encount several problem when display the grid.
And I am using carbide 3.1 in visual studio 2005.

1)VS provided a edit multi-icon definition when right click on teh miflist. Therefore, I used it, and it will generate the mbm/mbg. I assume it generate correct enum in the mbg although, the number started from 16384...

when I use where EMbmGrid1Fonetvcustom is a svg file :

AknIconUtils::CreateIconLC( GridEmailcustom,
GridEmailcustomM,
imagePath,
EMbmGrid1Fonetvcustom_m,
-1 );

CGulIcon* markIcon = CGulIcon::NewL( GridEmailcustom, GridEmailcustomM );

again no panic code happened.

but for bmp file, there is no way I can get pass this line. Most of the time I have is system error (-1001);

2)it leaves after

iGrid->HandleItemAdditionL();

code were follow

One more thing I am not sure, Is that it generate mif,mbm.
for the imagePath above, should I use mif/mbm

With Mif files the index starts usually with quite high number, but with MBM's the index should start with zero, so check that you are using correct index for different types of image files.

thx there, at least I learnt something about the mbg...

[stephen.cheung]

_LIT(KMyExFileName,"z:\\resource\\apps\\Gridtest1.mbm");
CFbsBitmap* aBitmap = new (ELeave) CFbsBitmap();
CleanupStack::PushL(aBitmap);
User::LeaveIfError(aBitmap->Load(KMyExFileName, 0));
gc.DrawBitmap(drawRect,aBitmap);
CleanupStack::PopAndDestroy();

after several days revisit, I have ensured that the mbm path is correct as the above display icons in the screen.

For the grid... following the example:...

http://wiki.forum.nokia.com/index.php/Grid_example

however, nothing show up when run, and if any navigation key presses, AknGridView 6 panics...

[symbianyucca]

have you modified the code ?
Also how many icons do you have & what index values are you using in the text array.

[stephen.cheung]

For the GetArrayL function, I implemented as below, with only one icon mbm added to the grid. Could it be the "CreateIconLC"
not quite correct

Thanks

CDesCArray* CGridtestView::GetArrayL(CArrayPtr<CGulIcon>* aIcon,
const TSize& aIconsize)
{
CDesCArrayFlat* MyArray = new(ELeave)CDesCArrayFlat(1);

CleanupStack::PushL(MyArray);

MyArray->AppendL( _L("1\tItem1") );
MyArray->AppendL( _L("1\tItem2") );
MyArray->AppendL( _L("1\tItem3") );
MyArray->AppendL( _L("1\tItem4") );
MyArray->AppendL( _L("1\tItem5") );
MyArray->AppendL( _L("1\tItem6") );
MyArray->AppendL( _L("1\tItem7") );
MyArray->AppendL( _L("1\tItem8") );
MyArray->AppendL( _L("1\tItem9") );
MyArray->AppendL( _L("1\tItem10") );

CFbsBitmap* GridEmailcustom = NULL;
CFbsBitmap* GridEmailcustomM = NULL;


TFileName fullName(imagePath);
//CompleteWithAppPath(fullName);//

AknIconUtils::CreateIconLC( GridEmailcustom,
GridEmailcustomM,
imagePath,
0,
1 );
CGulIcon* markIcon = CGulIcon::NewL( GridEmailcustom, GridEmailcustomM );
CleanupStack::Pop( 2 ); // gridMarkIcon, gridMarkIconMask
CleanupStack::PushL( markIcon );
aIcon->AppendL( markIcon );

// Append Text string to MyArray in here as "1\tMytext",
// where 1 is the zero based icon index
// also remember to load and add icons in here... and also set them
// to the right size */
CleanupStack::Pop(markIcon);
CleanupStack::Pop(MyArray);
return MyArray;
}

at least the indexing for icons is zero based, thus change the index 1 to 0 and it has a chance on working with only one icon in the icon array.
