char * GTreeItem::GetText (  int  i = 0  )  [virtual]

Get the text for the node. You can either return a string stored internally to your object by implementing this function in your item class or use the SetText function to store the string in this class. Reimplemented from GItem.

bool GTreeItem::SetText (  char *  s, int  i = 0 )  [virtual]

Sets the text for the node. This will allocate and store the string in this class. Reimplemented from GItem.

void GTreeItem::Update (   )  [virtual]

Tells the item to update itself on the screen when the GTreeItem::GetText data has changed. Reimplemented from GItem.
