Listbox Inside a form

[mubx2000]

Hi m I have a list of vendor names stored in a dynamic array , I designed a form that have the following information:

Customer Name:
Store No#: Address:

But I need also to Include on this form the following vendor list:
Vendor Name:
-Peter
-Welson
-Sally
.
.
.,etc

logically I think that I need to present the vendor names in (ListBox) so How I can include the list box on the form? If not possible how I present this data in list format ?
I need to Use a list box because the user will select the vendor name from a list to do further process and inquires.

In 2.x SDK check the Pop-up Field Example, it may help you out.

hi

Here is my example on preparing list box using file http://discussion.forum.nokia.com/fo...ad.php?t=77730


I haven't tried to place list in form, so i can't tell you about that.


Hope this helps.

It is Not Logic I need to display The Customer name and a list name for all vendors this customer deal with (Master Detail format).

I am assuming you are assuing CAknForm, you can add the listbox in the resource file using something like this ->

--------------------------
RESOURCE DIALOG r_aknexform_text_field_dialog
{
flags = * Whatever Flags u desire* ;
buttons = *Create your Button List and add it here;
form = r_aknexform_text_field_form;
}

RESOURCE FORM r_aknexform_text_field_form
{
items =
{
DLG_LINE
{
type = EEikListBox;
prompt = *Label for your form*;
id = EListBoxId;
itemflags = *If you want any*;
control = LISTBOX
{
flags = *Whatever Flags u want*;
array_id = r_demo_listbox_items;
}
}
}
}


RESOURCE ARRAY r_demo_listbox_items
{
items =
{
LBUF { txt = "Whatever u want to add here"; },
LBUF { txt = "Whatever u want to add here"; },
LBUF { txt = "Whatever u want to add here"; }
};
}

----

And then ofcourse if u want to access the listbox in your code u can always do something like..

CEikListBox* myListBox = (CEikListBox*)Control(EListBoxId);

and then use the listBox pointer to add/modify what u want progrmatically.

Thanks for your comment , the design above is sutible for static type of list box ,as I stated befoe that I want to Get The Names Of The Vendor from the database any way I'll test It today and tell you the result when I finish testing thanks again for your help I'm apprecited.

Hi,

Yes in that case what you can do is..leave the resource array empty..create the array progrmatically and then append it to the textbox by doing something like this ->

-----------------------
TInt count; // Get the array size in this var..using your code
CDesC16ArrayFlat* myArray = CDesC16ArrayFlat::NewL(count);
CEikListBox* myListbox = (CEikListBox*)Control(EMyListBoxId);
CTextListBoxModel* myListBoxModel = myListBox->Model();

// Append what all u need to append to the myArray

myListBoxModel->SetItemTextArray(myArray);
--------------
This should solve your problems...ofcourse make sure to take care of the Cleanupstack issues..as i have not pushed or popped anything in the code.

U can get the name vendor from your database and use
yourArray->AppendL(yourVendorName); // yourVendorName must be sincrone with your list

I wish help you.

I use code as following:

CEikListBox* myListBox = (CEikListBox*)Control(ESelectionListControl);
CTextListBoxModel* myListBoxModel = myListBox->Model();
myListBoxModel->SetItemTextArray(array);

but, error occur as following:

1.undefined identifier 'Control';
2.illegal implicit conversion from 'MListBoxModel *' to 'CTextListBoxModel *'

Thanks!

I use code as following:
CEikListBox* myListBox = (CEikListBox*)Control(ESelectionListControl);
CTextListBoxModel* myListBoxModel = myListBox->Model();
myListBoxModel->SetItemTextArray(array);[/I]

but, error occur as following:

1.undefined identifier 'Control';
2.illegal implicit conversion from 'MListBoxModel *' to 'CTextListBoxModel *'

1)i dont find a function named Control() in the class CEikListBox atleast in the public sdk.

2) i guess you need to use something like this.

CDesCArray* array = static_cast<CDesCArray*> (iListBox->Model()->ItemTextArray());

[mayankkedia]

That code should have worked...I will check it out..u could also try something like this then :-

----
// get listbox item array

MDesCArray* textArray = list->Model()->ItemTextArray();

CDesCArray* itemList = static_cast<CDesCArray*>(textArray);

// construct new item, build

_LIT(KNewItem, "New item..");

TBuf<32> item;

item.Format(_L("\t%S\t\t"), &KNewItem);

// append new item to the listbox

itemList->AppendL(item);

// update listbox

list->HandleItemAdditionL();
------------

This would work just fine in your case..and instead of that one item that has been added in the code..u can put a for loop or something and keep adding the contents till u have them..and then call handleitemaddition at the end of it..to update and redraw the listbox.
