Set the current position so that a given item is visible
int PtGenTreeShow( PtWidget_t *widget,
PtGenTreeItem_t *item );
This function sets the current position so that the given
item is visible.
If item is NULL, the function does nothing.
This lets you do something like this:
PtGenTreeShow( widget, PtGenTreeGetCurrent(widget) );
without checking whether
PtGenTreeGetCurrent()
returned a NULL value.
PtGenTreeShow() can be called with an item whose
ancestor is collapsed, in which case the ancestor will be expanded.
The value returned by the Tree Item State method.
