RasterTreeItem( parentItem, icon, text [, value [, isRoot]] )
Represents an item in a tree control. Tree items are not created by using this constructor directly, but rather using of theadd() method off the
tree or any treeItem instance.
The
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.
