List Box
The list box control com.sun.star.awt.UnoControlListBox displays a list of items that the user can select one or more of. If the number of items exceeds what can be displayed in the list box, scroll bars automatically appear on the control. If the Dropdown
property is set to True
, the list of items is displayed in a drop-down box. In this case, the maximum number of line counts in the drop-down box are specified with the LineCount
property. The actual list of items is controlled by the StringItemList
property. All selected items are controlled by the SelectedItems
property. If the MultiSelection
property is set to True
, more than one entry can be selected.
It may be easier to use the com.sun.star.awt.XListBox interface when working with list boxes, because an item can be added to a list at a specific position with the addItem
method. For example, an item is added at the end of the list by:
Dim nCount As Integer, oListBox As Object oListBox = oDialog.getControl("ListBox1") nCount = oListBox.getItemCount() oListBox.addItem( "New Item", nCount )
Multiple items are added with the help of the addItems
method. The removeItems
method is used to remove items from a list. For example, the first entry in a list is removed by:
Dim nPos As Integer, nCount As Integer nPos = 0 nCount = 1 oListBox.removeItems( nPos, nCount )
A list box item can be preselected with the selectItemPos
, selectItemsPos
and selectItem
methods. For example, the first entry in a list box can be selected by:
oListBox.selectItemPos( 0, True )
The currently selected item is obtained with the getSelectedItem
method:
Dim sSelectedItem As String sSelectedItem = oListBox.getSelectedItem()
The position of the currently selected item is obtained with the getSelectedItemPos
method:
Dim selectPos As Integer selectPos = oListBox.getSelectedItemPos()
