> ## The list

> ### Setting of the items by the method

> Use addItem method to add items to the list with a string and position. If the position is omitted, add it to the end of the list. The following program is a sample of adding item to the list.

>     #----------------------------------------------------------
>     #Function for the event procedure
>     #----------------------------------------------------------
>     def btnep1(object)
>       # Delete all the items of the list.
>       $newlist_001.delAll()
>       # Add an item to the last of the list.
>       $newlist_001.addItem("item1")
>       $newlist_001.addItem("item2")
>       $newlist_001.addItem("item3")
>       $newlist_001.addItem("item4")
>       # Add an item to the specified position of the list.
>       $newlist_001.addItem("item0",0)   # 0 :top
>       $newlist_001.addItem("item5",-1)  # -1 :last

>       # Update the modified list.
>       $newlist_001.updateList()
>     end

> ### Setting of the items by the property

> the property "data" can be used for setting the items of the list, if it is a comparatively little number of the items. In such case, set the property "dataSource" to WS_DATA_SOURCE_NONE, and set the items which is punctuated with comma every one item to the property "data".

>     #----------------------------------------------------------
>     #Function for the event procedure
>     #----------------------------------------------------------
>     def btnep1(object)
>       # Delete all the items of the list.
>       $newlist_001.delAll()

>       # Set the items of the list by the property
>       $newlist_001.setProperty("dataSource",Mpfc::WS_DATA_SOURCE_NONE)
>       $newlist_001.setProperty("data","item0\nitem1\nitem2\nitem3\nitem4")
>     end

> It is possible to indicate the specified ICON by icon file name as following program. Set True to the property "useIcon" and Set the items as following format. If it is omitted,the value of "iconPixmap" is used for default icon.

>       format:
>       ICON1filename,string1ofTheItem\n ICON2filename,string2ofTheItem\n...

>     #----------------------------------------------------------
>     #Function for the event procedure
>     #----------------------------------------------------------
>     def btnep1(object)
>       # Delete all the list of the list
>       $newlist_001.delAll()

>       # Set the items of the list by the property
>       $newlist_001.setProperty("dataSource",Mpfc::WS_DATA_SOURCE_NONE)
>       $newlist_001.setProperty("data",
>          "$(WSDIR)/sys/pixmaps/bi16.xpm,item1\nitem2\nitem3")
>     end

> ### Setting of the items from the file directly

> It is possible to set the items from the file directly. In such case at first,set WS_DATA_SOURCE_FILE to the property "dataSource", and set the file name to the property "dataSourceName" as following program.

>     #----------------------------------------------------------
>     #Function for the event procedure
>     #----------------------------------------------------------
>     def btnep1(object)
>       # Delete all the items of the list
>       $newlist_001.delAll()

>       # Set the items from file directly
>       $newlist_001.setProperty("dataSource",Mpfc::WS_DATA_SOURCE_FILE)
>       $newlist_001.setProperty("dataSourceName","data.txt")
>     end

>     # data.txt contains...
>     $(WSDIR)/sys/pixmaps/bi16.xpm,item1
>     item2
>     item3
>     item4
>     $(WSDIR)/sys/pixmaps/bi16.xpm,item5
>     item6
>     item7
>     item8

> ### Setting of the items from the other instance

> It is possible to set the items from the data source target property of the other instances. In such case, set WS_DATA_SOURCE_INSTANCE to the property "dataSource", and set the instance name to the property "dataSourceName". In the following example, a WSCtextField instance are specified to the property "dataSourceName" and then it sets the string data of it to the list.

>     #----------------------------------------------------------
>     #Function for the event procedure
>     #----------------------------------------------------------
>     def btnep1(object)
>       # Delete all the items of the list
>       $newlist_001.delAll()

>       # Set the items from the other instances
>       $newlist_001.setProperty("dataSource",Mpfc::WS_DATA_SOURCE_INSTANCE)
>       $newlist_001.setProperty("dataSourceName","newtext_000")
>     end

> The following picture indicates the list(lower side) from the other instance of WSCtextField class( upper side).
