Need Help with grid here

[gigglie]

I am trying to implement a grid fully from resource , as it would be a static one only . I have done till this . Right now I want to show some text in it .My problem is that the grid do not show . Do I need to add something ?

RESOURCE GRID r_selectiongrid
{
//height = 5; // in items
//width = 10; 
flags = EAknListBoxSelectionGrid;
style = r_selectiongrid_style;
array_id = r_selectiongrid_items;
}

RESOURCE GRID_STYLE r_selectiongrid_style
{
layoutflags = EAknGridHorizontalOrientation |EAknGridLeftToRight | EAknGridTopToBottom;
primaryscroll = EAknGridFollowsItemsAndLoops;
secondaryscroll = EAknGridFollowsItemsAndLoops;
itemsinprimaryorient = 3;
itemsinsecondaryorient = 3;
gapwidth = 5;
gapheight = 5;
width = 50;
height = 50;
}

RESOURCE ARRAY r_selectiongrid_items
{
items =
{
LBUF { txt = "aaa"; },
LBUF { txt = "bbb"; },
LBUF { txt = "ccc"; },
LBUF { txt = "ddd"; },
LBUF { txt = "eee"; },
LBUF { txt = "fff"; },
LBUF { txt = "ggg"; },
LBUF { txt = "hhh"; },
LBUF { txt = "iii"; }
};
}

I am implementing the view class as the container for grid .

void CSimpleGridAppView::ConstructL( const TRect& aRect )
{
CreateWindowL();
	// Set the windows size
	SetRect( aRect );
	// Activate the window, which makes it ready to be drawn
	ActivateL();
	iGrid = new( ELeave ) CAknGrid;
	iGrid->SetContainerWindowL( *this );
	TResourceReader reader; 
	CEikonEnv::Static()->CreateResourceReaderLC(reader, R_SELECTIONGRID);
	iGrid->ConstructFromResourceL(reader);
         iGrid->ActivateL();
        // Setup text foreground and background colors to default
       AknListBoxLayouts::SetupStandardGrid( *iGrid );
       // Setup the graphics subcell
      AknListBoxLayouts::SetupFormGfxCell(
       *iGrid, // Reference to grid control
        iGrid->ItemDrawer(), // Pointer to the item drawer
        0, // Column index
        0, // Left position
        0, // Top position
        0, // Right - unused
        0, // Bottom - unused
        50, // Width
        32, // Height
         TPoint(0,0), // Start position
         TPoint(32, 32)); // End position

       AknListBoxLayouts::SetupFormTextCell(
        *iGrid, // Reference to grid
         iGrid->ItemDrawer(), // Pointer to the item drawer
         1, // Column index
         LatinBold12(), // Font
         215, // Color (215 = black)
         0, // Left margin
         0, // Right margin - unused
         50 - 3, // Baseline
         50, // Text width
         CGraphicsContext::ECenter, // Text alignment
         TPoint(0, 32), // Start position
         TPoint(50, 50)); // End position
       
	iGrid->SetFocus(ETrue);
	iGrid->DrawNow();

	CleanupStack::PopAndDestroy();
}

I suggest you use a working example as a starting point. Check the sdk examples, wiki or similar resources.

Hi PushL
Do you know 1 working example , please give to me if you have one .

RESOURCE GRID R_SIMPLEGRID_GAMES_GRID
{
array_id = r_simplegrid_games_grid_items;
flags = EAknListBoxSelectionGrid;
style=r_simplegrid_games_grid_style;
}




RESOURCE ARRAY r_simplegrid_games_grid_items
{
items =
{
LBUF
{
txt = GAMES_GRID_ITEM1_TEXT;
},
LBUF
{
txt = GAMES_GRID_ITEM2_TEXT;
},
LBUF
{
txt = GAMES_GRID_ITEM3_TEXT;
},
LBUF

txt = GAMES_GRID_ITEM4_TEXT;
},

},

},

}

};
}

gapwidth=5;
gapheight=5;
height = 68;
width = 50;

Hi PushL
Do you know 1 working example , please give to me if you have one .

Did you check the sdk doc? See Developer Guides >> Avkon UI Resources – Grids
It contains most of what you'd ever need..

[gigglie]

I was working with the S60 Avkon grid documentation and forums here and all I could translate was above code . So I was kind of trying to make it work following the instructions there .

[gigglie]

void CSimpleGridGamesGrid::SetupGridIconsL(TInt aIconFileResource)
{
// Get the name of the file containing the icons
HBufC* iconFileName;
iconFileName = StringLoader::LoadLC(aIconFileResource); // Pushes iconFileName onto the Cleanup Stack.

// Create an array of icons, reading them from the file
CArrayPtr<CGulIcon>* icons = new(ELeave) CAknIconArray(KNumberOfIcons);
CleanupStack::PushL(icons);
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridSnap, EMbmSimplegridCard_mask));
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridGolf, EMbmSimplegridCard_mask));
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridClock, EMbmSimplegridCard_mask));
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridAces, EMbmSimplegridCard_mask));
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridHearts, EMbmSimplegridCard_mask));
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridRummy, EMbmSimplegridCard_mask));
icons->AppendL(iEikonEnv->CreateIconL(*iconFileName, EMbmSimplegridPoker, EMbmSimplegridCard_mask));
CleanupStack::Pop(icons);
CleanupStack::PopAndDestroy(iconFileName);

ItemDrawer()->FormattedCellData()->SetIconArray(icons); // passing ownership of icons

}

Hi Kamal , but I was yet to implement the icon bit , I was only trying the elementary text thing . If they show up right I would be soon to follow with this one . But thanx for your help buddy.
