Set the position so that the specified item is visible
int PtTreeShow( PtWidget_t *widget,
PtTreeItem_t *item );
This function sets the current position so that the given
item is visible. If you pass item as NULL,
the function does nothing.
This lets you do something like this:
PtTreeShow( widget, PtTreeGetCurrent(widget) );
without checking to see if PtTreeGetCurrent() returned
NULL.
- 0
- Success.
- Nonzero
- item belongs to a collapsed subtree, and a callback
function prevented the subtree from being expanded
