RasterTree( parent, icon, text )
Creates a tree control. Tree controls take the entire area of their parent container. TheRasterTree class extends the RasterTreeItem class,
thus all RasterTreeItem methods apply to the RasterTree
object.
The following code creates a tree control inside a document element with an
id of "treeDiv":
var mytree = new Tree( "treeDiv", ICONS16.COMPUTER, "My System"); mytree.add( ICONS16.BOOK_OPEN, "Help Topics"); //add 1st item var item = mytree.add( ICONS16.CALENDAR, "Add Event"); //add 2nd item item.add( ICONS16.PAGE, "Birthday Party"); //add child in 2nd item aboveThe
icon URL might be prefixed by Raster resource-folder tag. The prefix
"IMG:" is replaced with the current raster/images location, for example:
"IMG:icon.gif" resolves to "$RASTER_HOME$/images/icon.gif". The prefix "CSS:"
is replaced with the current css themes images location, for example:
"CSS:icon.gif" resolves to "$RASTER_HOME$/themes/$THEME$/images/icon.gif".
Do not place a "/" between the prefix and the rest of the URL, as a forward slash will be inserted automatically. For configuring the RASTER_HOME and THEME use the
Raster.config() method.
