|Status||resolved||Product Version||Daily / GIT|
|Summary||0004064: JvDBTreeView, 4 bugs; Add Node IconField; unique MasterField; delete childs; drag&drop|
I use JvDBTreeView for a Delphi project. While using it I have found and fixed 4 bugs. See attached source.
1) Add Node, IconField, value set, same value as parent
IconField was not populated during node creation, resulting in a node without icon
2) Add Node, MasterField, unique value ensured
Current routine counts the records and adds 1 for the next node MasterField. This does not work when nodes in between have been deleted. Unique key violation.
The record count is used as a start value for a loop to find the first unused MasterField value.
3) Delete node, delete records for all childs
Only the selected record was deleted on the database, but not records from child nodes. The child nodes were not visible since the MasterField â€“ DetailField connection was lost, but the child records were still on the database. Rekursive child deletion added.
4) Drag&drop, move node only for node drop, not for drop of other objects
Drop to the tree and within the tree have to be handled separately. Otherwise drop distorts tree.
I have added 3 additional properties with I need for my project (www.bookpiles.org). I can make the source avalable, if wanted, but it's not included in this fix. The additional properties are:
Additional text for tree nodes, stored in additional db column, can be used to show counters for each node like in Outlook
- UseInfo, switch to use InfoField
- ResevedNodes, I need a reserved number range for node id's. So that I can add nodes with given id's later

|Your changes are now in SVN. For the rest of your proposition, I'm afraid this is too specific to your use case and might have bad consequences for regular users.|
