Set the selection indexes
int PtFSSetSelIndexes( PtWidget_t *widget, const unsigned short *buffer, int count );
This function sets the selection indexes. The function assumes that buffer points to a sorted array of indexes. The first item in the widget has an index of 1, not 0.
The function returns the number of items that have been actually selected, which may be smaller than count if the array isn't sorted or contains duplicate indexes or indexes that are out of range.
|If the selection mode is Pt_RANGE_MODE, only the first index and the count are used.|
The number of items selected.
