sys.tv_getsel()

Purpose:
sys.tv_getsel() returns the index of the currently selected item for the TreeView program.
Usage:
idx = sys.tv_getsel();
Arguments:

None
Returns:
-1 - Program is not a TreeView program or program is not open yet. 0 - OK
Where Used:
sys.tv_getsel() should be used in the TVSelectPCL or the TVActionPCL.
Example:
See the sys.menu.tv program for an example of how to use sys.tv_getsel().
Description:
sys.tv_getsel() returns the index of the currently selected item for the TreeView program. The index is based on the order the items were added to the TreeView program. The first item always has an index of 0 and the last item always has an index of nitems-1. The easiest way for an application to know what info goes with a particular item is to build a temp file, indexed by item idx, while adding items to the TreeView program. Sys.tv_getsel() can then be used to set the key for the temp file when the TVSelectPCL or TVActionPCL is executed.
