Adds an item to a list control or object.
|
To add an item to |
Use |
|---|---|
|
A ListBox or DropDownListBox control |
|
|
A PictureListBox, DropDownPictureListBox, and RibbonComboBoxItem control |
|
|
A ListView control when you only need to specify the item name and picture index |
|
|
A ListView control when you need to specify all the properties for the item |
|
|
A PDFTableOfContents and PDFTableOfContentsItem objects |
Description
Adds a new item to the list of values in a list box.
Applies to
ListBox and DropDownListBox controls
Syntax
listboxname.AddItem ( item )
|
Argument |
Description |
|---|---|
|
listboxname |
The name of the ListBox or DropDownListBox in which you want to add an item |
|
item |
A string whose value is the text of the item you want to add |
Return value
Integer.
Returns the position of the new item. If the list is sorted, the position returned is the position of the item after the list is sorted. Returns -1 if it fails. If any argument's value is null, AddItem returns null.
Usage
If the ListBox already contains items, AddItem adds the new item to the end of the list. If the list is sorted (its Sorted property is true), PowerBuilder re-sorts the list after the item is added.
A list can have duplicate items. Items in the list are tracked by their position in the list, not their text.
AddItem and InsertItem do not update the Items property array. You can use FindItem to find items added at runtime.
Adding many items to a list with a horizontal scroll bar
If a ListBox or the ListBox portion of a DropDownListBox will have a large number of items and you want to display an HScrollBar, call the SetRedraw function to turn Redraw off, add the items, call SetRedraw again to set Redraw on, and then set the HScrollBar property to true. Otherwise, it may take longer than expected to add the items.
Examples
This example adds the item Edit File to the ListBox lb_Actions:
integer rownbr string s s = "Edit File" rownbr = lb_Actions.AddItem(s)
If lb_Actions contains Add and Run and the Sorted property is false, the statement above returns 3 (because Edit File becomes the third and last item). If the Sorted property is true, the statement above returns 2 (because Edit File becomes the second item after the list is sorted alphabetically).

Description
Adds a new item to the list of values in a picture list box.
Applies to
PictureListBox, DropDownPictureListBox, and RibbonComboBoxItem controls
Syntax
listboxname.AddItem ( item {, pictureindex } )
|
Argument |
Description |
|---|---|
|
listboxname |
The name of the PictureListBox or DropDownPictureListBox or RibbonComboBoxItem in which you want to add an item |
|
item |
A string whose value is the text of the item you want to add |
|
pictureindex (optional) |
An integer specifying the index of the picture you want to associate with the newly added item |
Return value
Integer.
Returns the position of the new item. If the list is sorted, the position returned is the position of the item after the list is sorted. Returns -1 if it fails. If any argument's value is null, AddItem returns null.
Usage
If you do not specify a picture index, the newly added item will not have a picture.
If you specify a picture index that does not exist, that number is still stored with the picture. If you add pictures to the picture array so that the index becomes valid, the item will then show the corresponding picture.
For additional notes about items in list boxes, see Syntax 1.
Example 1
This example adds the item Cardinal to the PictureListBox plb_birds:
integer li_pic, li_position
string ls_name, ls_pic
li_pic = plb_birds.AddPicture("c:\pics\cardinal.bmp")
ls_name = "Cardinal"
li_position = plb_birds.AddItem(ls_name, li_pic)If plb_birds contains Robin and Swallow and the Sorted property is false, the AddItem function above returns 3 because Cardinal becomes the third and last item. If the Sorted property is true, AddItem returns 1 because Cardinal is first when the list is sorted alphabetically.
Example 2
This example adds two items to the ribbon combo box:
Integer li_Return
RibbonComboBoxItem lr_ComboBox
li_Return = lr_ComboBox.SetBoxPictureList("PaperSizeA0Small!,PaperSizeA1Small!")
li_Return = lr_ComboBox.AddItem("Item1")
li_Return = lr_ComboBox.AddItem("Item2",1)

Description
Adds a chapter to the table of contents.
Applies to
PDFTableOfContentsItem objects
Syntax
PDFTableOfContentsItem AddItem(PDFText chapterObject)
PDFTableOfContentsItem AddItem(PDFTextBlock chapterObject)
PDFTableOfContentsItem AddItem(string tocItemText, PDFPage chapterObject)
|
Argument |
Description |
|---|---|
|
chapterObject |
The text, textblock (heading), or PDF page to add for a chapter in the table of contents. |
|
tocItemText |
The chapter title in the table of contents that links to the PDF page. |
Return value
PDFTableOfContentsItem objects. Returns the table of contents item created in the table of contents if the function succeeds, or returns null if the function fails.
Usage
Use this syntax to add chapters to the table of contents. The AddItem function of PDFTableOfContents adds the level-1 chapters; and the AddItem function of PDFTableOfContentsItem adds the sub-level chapters.
The chapterObject is added to both the table of contents, and to a PDFPage. Then, the chapterObject in the table of contents is linked to the actual chapter in the PDFPage.
Examples
This example adds level-1 and level-2 chapters to the table of contents and have them linking to the actual chapter in the document:
PDFDocument lpdf_doc
PDFpage lpdf_page,lpdf_page1
