This field allows you to control the expanded/collapsed state of the items when the tree is created or re-entered. Set the field to a value between 0 and 63, indicating the maximum level to expand (0=all items collapsed so that only the level 0 items are visible, 63=all items expanded). You may optionally specify one of the two flags listed below:
Symbol |
Value |
Description |
|---|---|---|
XTEXPF_SAVE |
&h40 |
Save current expand/collapse status on exit |
XTEXPF_RESTORE |
&h80 |
Restore saved status (on XTROP_REPLACE reentry) |
Notes
XTEXPF_SAVE can be used with any of the level values (0-63) in XTR.EXPANDLEVEL to start out with the specified uniform level of expansion but save the user-modified status on exit. But XTEXPF_RESTORE overrides all other options unless there was no previously saved status, in which case XTEXPF_RESTORE is ignored.
XTEXPF_RESTORE assumes that the order of the rows has not changed since the previous exit from that tree. Since the expand/collapse status is associated only with the row numbers as displayed, changing the sort order on reentry would result in the wrong items being expanded or collapsed.
