Description

This class holds information from a Pt_CB_TREE_STATE or Pt_CB_TREE_SELECTION callback, which are generated when a PtTreeItem is selected.

Instance Variables

click_count: The number of times the mouse button has been clicked on the item.
expand: An integer used with Pt_CB_TREE_STATE to prevent expansion. 0 allows expansion to occur, any non-zero value prevents it.

nitems: The number of items selected, not including collapsed subtrees.
sel_mode: A number indicating the current selection mode. For details, see Pt_ARG_SELECTION_MODE in the PtGenList section of the Photon documentation.
