Examples
The following example shows a call to the getNextItem method to retrieve the number of the next item in the form list control.
The while select statement retrieves account numbers from the CustTable table and then stores the data in a container. The items in the variable are added to the form list control.
static void createForm2(Args _args)
{
Args args;
Form form;
FormRun formRun;
FormBuildDesign formBuildDesign;
FormBuildDataSource formBuildDataSource;
FormBuildListControl formBuildListControl;
FormListControl formListControl;
FormListItem formListItem;
DictTable dictTable;
int idx4;
boolean columnadd;
str string;
container conAccountNum;
CustTable custTable;
int numAccounts;
int i;
int item;
// Create the form header.
form = new Form();
// Add data sources to the form.
dictTable = new DictTable(77);
formBuildDataSource = form.addDataSource(dictTable.name());
formBuildDataSource.table(dictTable.id());
// Create the form design.
formBuildDesign = form.addDesign("Design");
formBuildDesign.caption("myForm");
// Add a form list control.
formBuildListControl =
formBuildDesign.addControl(FormControlType::ListView,"List");
idx4 = formBuildListControl.id();
args = new Args();
args.object(form);
// Create the run-time form.
formRun = new FormRun(Args);
formRun.run();
formRun.detach();
formListControl = formRun.control(idx4);
// Add an item to the form list control.
while select custTable
where custTable.AccountNum >=
"4000" && custTable.AccountNum <= "4040"
{
conAccountNum += [[custTable.AccountNum]];
}
numAccounts = conlen(conAccountNum);
for(i = 1; i <= numAccounts; i++)
{
string = conPeek(conAccountNum,i);
formListItem = new FormListItem(string);
formListControl.addItem(formListItem);
}
item = formListControl.getNextItem(FormListNext::ToRight);
}
