[symbee]

Hi to all,

I m making grid application.

in view.cpp file,

void ChellogridAppView::ConstructL( const TRect& aRect )
{
CreateWindowL();

iGrid = new( ELeave ) CAknGrid;
iGrid->SetContainerWindowL( *this );
TResourceReader reader;
CEikonEnv::Static()->CreateResourceReaderLC(reader, R_SELECTIONGRID);
iGrid->ConstructFromResourceL(reader);
iGrid->ActivateL();

iGrid->SetFocus(ETrue);
iGrid->DrawNow();

CleanupStack::PopAndDestroy()

SetRect( aRect );

ActivateL();
}
an in .rss file

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 = 20;
height = 20;
}

RESOURCE ARRAY r_selectiongrid_items
{
items =
{
LBUF { txt = "aaa"; },
LBUF { txt = "bbb"; },
LBUF { txt = "ccc"; },
LBUF { txt = "ddd"; }

};
}

My problem is the program do not show me grid but yes only scroll bar.

Hi!

What kind of grid u wanna show?

Have u implemented SetLayoutL(--) ,AknListBoxLayouts::SetupFormGfxCell(--)
or AknListBoxLayouts::SetupFormTextCell(--) functions?

Where u have user "RESOURCE GRID_STYLE r_selectiongrid_style"?

U can do it without resource also effectively.

Check the Grid example on SDK. It will help u.

Download "Series_60_DP_Avkon_UI_Resources_Grids_v1_0_en.pdf "
from forum.

Thank u very much for reply.

First I wanna show selection grid, than i'll move on to menu grid.

Where I should implement SetLayoutL(--) ,AknListBoxLayouts::SetupFormGfxCell(--)
or AknListBoxLayouts::SetupFormTextCell(--) functions bcoz I havn't implemented anywhere in my application.

I have given my .rss code in which i have used RESOURCE GRID_STYLE r_selectiongrid_style.

that pdf file is currupted, i can't use it!

I m using sdk 3.0 and symbian 9.0. there is no grid eample given:-(

Any pointers regarding this ma'm?

Thanks again

Hi,

I have implemented iGrid->SetLayoutL(50,20,20,3,3,TSize(300, 300),5,5);

But there is no difference in output! Only scrollbar!

Plz help

Hi!
plz check the function and every parameter
void CAknGrid::SetLayoutL ( TBool aVerticalOrientation,
TBool aLeftToRight,
TBool aTopToBottom,
TInt aNumOfItemsInPrimaryOrient,
TInt aNumOfItemsInSecondaryOrient,
TSize aSizeOfItems,
TInt aWidthOfSpaceBetweenItems = 0,
TInt aHeightOfSpaceBetweenItems = 0
)

What TSize u have specified?? (300, 300) why so large??

did u forget to put any text or graphic to display??

Check AknListBoxLayouts::SetupFormTextCell() n related functions.

Follow the link :
http://www.forum.nokia.com/info/sw.n..._0_en.pdf.html

to download the file once again.

Check the pdf once again. It will help u.

Thanx again Shilpa,

I have changed size by (30,30) and in rss file,
RESOURCE ARRAY r_selectiongrid_items
{
items =
{
LBUF { txt = "aaa"; },
LBUF { txt = "bbb"; },
LBUF { txt = "ccc"; },
LBUF { txt = "ddd"; }
};

Doesn't it sufficient to display aaa,bbb,ccc and ddd in grid?

Why should I use AknListBoxLayouts::SetupFormTextCell() becoz in that pdf there is only mentioned as I previously discussed in my code!!

I have used SetExtent and by that I got some grid structure but no text appears!
plz reply

Regards

Hi!

SetupFormTextCell (--) setups a single text cell of list item .
U call it after setting the layout for the grid.

Also call SetPrimaryScrollingType() n SetSecondaryScrollingType() properly

Check the following function definition

void AknListBoxLayouts::SetupFormTextCell ( CEikListBox & aListBox,
CFormattedCellListBoxItemDrawer * aItemDrawer,
TInt index,
const CFont * font,
TInt ,
TInt lm,
TInt ,
TInt B,
TInt W,
CGraphicsContext::TTextAlign aAlign,
TPoint p1,
TPoint p2
)

1st parameter will be *iGrid .
2nd iGrid ->ItemDrawer()
3rd 0 ie the column index ie in ur list string format text column number
LatinBold12(),
215, // Color (215 = black)
25, // Left margin
0, // Right margin - unused
20, // Baseline
25, // Text width
CGraphicsContext::ELeft, // Text alignment
TPoint(24,0), // Start position
TPoint(28, 28) // End position

U set the start and end position as per ur requirement.

Dont forget to call DrawNow() after this.

Make some variations in numeric values if required e.g for baseline or margin.

I hope u have implemted SizeChanged() properly.

Bye.

Still any problem exist then tell me.

Hey

Thanks a lot for ur help. I got text on my grid buttons!:-)

Actually I want to create menu grid and i have read from sdk help.

But I m not clear about second phase constructor and In my program

------------------------------------------------------------------------
iGrid = new( ELeave ) CAknGrid;
iGrid->SetContainerWindowL( *this );
TResourceReader reader;
CEikonEnv::Static()->CreateResourceReaderLC(reader, R_SELECTIONGRID);

CAknPopupList* popupList = CAknPopupList::NewL( iGrid,R_AVKON_SOFTKEYS_SELECT_BACK );
CleanupStack::PushL(popupList);
popupList->SetTitleL(_L("Menu grid"));

iGrid->ConstructL( popupList, CEikListBox::ELeftDownInViewRect );

iGrid->ConstructFromResourceL(reader);
iGrid->ActivateL();
iGrid->SetLayoutL(50,50,50,3,3,TSize(60, 60),30,30);
iGrid->SetExtent(TPoint(40,40),TSize(150, 150));
iLayout->SetupFormTextCell(*iGrid,iGrid ->ItemDrawer(),0 ,LatinBold12(),215,25,0, 20,25,
CGraphicsContext::ELeft,TPoint(24,0),TPoint(28, 28) );

TInt popupOk = popupList->ExecuteLD();

CleanupStack::Pop(); // popupList


iGrid->MakeVisible(ETrue);
iGrid->SetFocus(ETrue);
iGrid->DrawNow();

CleanupStack::PopAndDestroy();//reader
----------------------------------------------------------------------
As output I get title "Menu grid" and grid as it looked earler in selection grid.

Also text doesn't appear. and it doesn't look like menugrid as shown in sdk help! I want to create grid like buttons at the top of screen

Thanx in advance

Hello everybody,

I´m trying to code the same example, but I am not successful. Perhaps you are so kind to post your (complete) code of xxxAppView.cpp?
This would be very nice, because I already try to solve my problem for hours...

I will check it.

I can guide the procedure how to make it .I have used the bitmaps bmconv similar to the lower version.Make some changes in the rss and grid file.

I cannot submit all the code as i'm binded with the legal ethics(NDA). But still i will guide u how to make it workable...

Tanks a lot! That would be nice!

First of all: I´m very new to Symbian and I´m using Carbide.c++ express.

I am trying to copy the example of the "S60 Platform: Avkon UI Resources - Grids" source.
Everything works fine, there is no error at compilation, but all I see in the emulator ist .... nothing!
I copied the example below, but this wasn´t successful either. I just want to have a selection menu with 5 Icons. Nothing more, nothing less... but this is really disapointing me.
So I started already from the very beginning:

void CGridmenuAppView::ConstructL( const TRect& aRect )
    {
   
	CreateWindowL();
	
	CAknGrid* iGrid = new( ELeave ) CAknGrid;
	iGrid->SetContainerWindowL( *this );
	TResourceReader reader;
	CEikonEnv::Static()->CreateResourceReaderLC(reader, R_SELECTIONGRID);
	iGrid->ConstructFromResourceL(reader);
	iGrid->ActivateL();
	
	iGrid->SetFocus(ETrue);
	iGrid->DrawNow();
	
	CleanupStack::PopAndDestroy();
	
	SetRect( aRect );
	
	ActivateL();

    }

So, there nothing happens... no error, but also no result.
