These new character search mode options are set via a new field in the XTRCTL structure (XTR'SEARCHMODE):
xtr'targetcol |
B,1 |
|
xtr'nfselstyle |
B,1 |
|
xtr'searchmode |
B,1 |
|
The options are defined as follows (in ASHINC:XTREE.DEF)
Symbol |

XTRSRCH_TOP_ONEX |
4 |

Previously, mode 0 (XTRSRCH_TOP_ALL) was always set. The options can be understood as follows:
| • | "_TOP" vs. "_NXT": Indicates whether the search operation always restarts from the top, or from the current item. In the latter case, it wraps from the bottom back to the top. |
| • | "_ALL" vs. "_ONE": Indicates whether the search is based on all the characters in the cells of the current column, or just the one first character. In the _ALL case, characters typed within 1 second of the previous character are added to the search key; after 1 second, the key is reset. So for example if you type "AB" within 1 second of each other, it will search for items starting with the combination "AB" (not case sensitive). If more than 1 second passed between the "A" and the "B", it restarts the search looking for items beginning with "B". The "_ONE" option effectively sets the timer to zero, so that each character typed restarts the search. |
| • | "X" (_ALLX, _ONEX): The "X" on the end indicates that collapsed child items are skipped. Otherwise, the search considers all items, and if it matches a collapsed child item, that child and all its siblings and parents are expanded. |
