Class TableCell

java.lang.Object
  com.novell.emframe.dev.dataTable.TableCell

Direct Known Subclasses:

CheckboxTableCell, IconTableCell, LinkTableCell, TextTableCell

public abstract class TableCell

extends java.lang.Object

Abstract class representing an individual cell in a simpleTable. This abstract class only contains a value.

Here is an example of using the simpleTable tag libary in a JSP:

<iman:dataTable titleKey="RBS.AvailableModules" titleBundle="FwResources" menuItems="${menuItems}" columnHeaders="${columnHeaders}" tableData="${tableData}" menuActionHandler="contentEventHandler" linkActionHandler="contentLinkActionHandler" />

For the tableData variable of the simpleTable tag Library (ex. tableData="${tableData}"), you would pass an TableCell[][] double array. The TableCell[][] array can contain TextTableCell, IconTableCell, LinkTableCell, and CheckboxTableCell objects.

For example, here is how you could create the TableCell[][] double array:

List theList = (List)request.getAttribute("availableModules"); // Data for the table
TableCell[][] tableData = new TableCell[theList.size()][];
int index = 0;
for(Iterator iterator = theList.iterator(); iterator.hasNext(); index++)
{
// ModuleData is the data being displayed in this table
ModuleData element = (ModuleData)iterator.next();
tableData[index] = new TableCell[4];
String iconUrl = "dev/dir/rbsModule2.gif";
tableData[index][0] = new IconTableCell(c.string("RBS.Module"), iconUrl, "module");
tableData[index][1] = new TextTableCell(element.getModuleDisplayName(), element.getModuleFDN());
tableData[index][2] = new LinkTableCell(element.getModulePackageName(), element.getModulePackageName());
tableData[index][3] = new CheckboxTableCell("true");
}
request.setAttribute("tableData", tableData);

This example would show four columns of data: the first an icon, the second text displaying the name of the module, the third a URL with a link to the module, and fourth a checkbox that is checked.
