Short: NListtree.mcc V1.1 (18.2) MUI list tree class with multiselection
Uploader: cs@aphaso.de (Carsten Scholling)
Author: cs@aphaso.de (Carsten Scholling)
Type: dev/mui
Requires: OS2.x, MUI3.8
Version: 1.1
Description:
¯¯¯¯¯¯¯¯¯¯¯
This MUI custom class provides you with an easy way of displaying list
entries in a sorted form, a so called tree-structure. A Tree-structure
will be selected, when data should be optical seperated from each other.
NListtree is intresting for programmers and the end-user also and easy to
use. So far as implemented by the programmer and needfull in the
application environment, this class allows the fully free recreation of the
list using drag&drop (short d&d) with support of multiselection.
First time in a list tree class it is possible to move complete
structures. That means, that the complete tree of the moved entry, back to
the root-list, is recreated at the destination if the programmer allows
this. The same for copying entries, which is also implemented.
Requirements:
¯¯¯¯¯¯¯¯¯¯¯¯
- OS2.x
- MUI3.8
Installation:
¯¯¯¯¯¯¯¯¯¯¯¯
- Simply use the supplied installer script.
History:
¯¯¯¯¯¯¯
V18.3 - Public release
- MUA_NListtree_Quiet does not work as expected (reported by Thomas
Igracki, Thx!)
- User defined compare- and findname-hooks crash! Fixed! (reported by
Thomas Igracki, Thx!)
- Now, NListtree is really quiet if MUIA_NListtree_Quiet is set!
- Reactivation of copied, moved and exchanged entries works better now.
- OpenAutoScroll now works as expected, added new config item Open
scroll (Thx to Matthias Bethke).
V18.2 - Public release
- Added multiselection feature
- Fixed some small cosmetical problems
- Implemented arrows as MUI images
- Implemented Copy method
- Implemented KeepStructure flag for recreation of the complete
structure in Move and Copy
V18.1 - Internal release
- Completely rewritten graphics stuff. Now in all cases predefined and
precreated images where used. This fixes many graphic bugs occured
in the old 18.0.
- After deleting an entry, the old entry remains internally active.
Using this entry crashed the machine. Fixed!
- Moving marker with the cursor keys did not trigger
MUIA_NListtree_Active. Fixed!
- When deleting entries, MUIA_NListtree_Active was triggered two times.
Fixed
- Deleting an entry without entries in the list caused recursive
function calling and stack overflow ;-) Fixed!
- Insertion had some bugs which caused the machine to hang or crash.
Fixed!
