IDropDown

Interface IDropDown

All Superinterfaces:
ICellLinkControl, ICellLinkControlT<Integer>, IControl, IControlT<IDropDown>, ISelector, ISelectorT<DropDownItem,IDropDownItemList>
public interface IDropDown extends IControlT<IDropDown>, ISelectorT<DropDownItem,IDropDownItemList>
Represents a drop-down form control.

A drop-down control displays a list of DropDownItem objects and lets users choose a single item from the list. Use IControlCollection.addDropDown(double,double,double,double) to add a drop-down control to a worksheet, then populate it through ISelectorT.getItems() or bind it to a worksheet range through the inherited selector APIs.


 IDropDown dropDown = worksheet.getControls().addDropDown(20, 20, 120, 20);
 dropDown.getItems().add(new DropDownItem("Pending"));
 dropDown.getItems().add(new DropDownItem("Approved"));
 dropDown.setDropDownLines(4);
 dropDown.setSelectedIndex(0);
