- Short: New datatypes.library, V45.4
- Author: GISBURN@w-specht.rhein-ruhr.de (Roland Mainz)
- Uploader: GISBURN@w-specht.rhein-ruhr.de (Roland Mainz)
- Type: util/libs
-
- Requires: util/libs/dtypeslib453.LhA
-
- New "datatypes.library", V45.4.
-
- ---- NOTE ----
-
- This archive is only a a quickly build archive to get something working for the
- "Computer 97'" fair in Colone/Germany. The main archive follows (or V45.5)
-
- ---- NOTE ----
-
-
- This project replaces the old datatypes.library V40.6 from CBM.
-
- NOTE: This is a "Preview"-Release, many things (like the example code) are currently unter construction
- (except the library itself; it's finished).
-
- Changes since V45.3:
- V45.4
- - Recompiled with SAS/C 6.58.
- This may fix mc68060 related problems (I was searching for this
- mc68060 incompatibility a long time :-(( ).
-
- - Fixed a bug in LaunchToolA that the given strings were not
- freed on some conditions.
- Fixed.
-
- - Fixed a bug (race condition) in RemoveDTObject that
- DTM_REMOVEDTOBJECT was executed BEFORE internal RemoveGadget.
- Now DTM_REMOVEDTOBJECT is correctly executed AFTER RemoveGadget.
-
- - Internal Delay's (when waiting for flags in RemoveDTObject and
- DisposeDTObject etc.)
- have been reduced from 1/2 sec down to 1/5 sec.
-
- - StartDragSelect now sets Result2 (IoErr()) with valid return
- codes.
-
- - All library calls to datatypes.library are now going througth
- the LVO explicitly.
-
- - ObtainDataTypeA has been rewritten to get more speed.
- This fixes also some bugs, see below.
-
- - ObtainDataTypeA: Fixed the bug that a 0 in the comparisation mask
- was treated as an empty mask field.
- Now the 0 is correctly recognized.
- This fixes the bug with the QRT descriptor and some other formats.
- Fixed.
-
- - ObtainDataTypeA: Endless loop in conjunction with "PostScript"
- descriptors and "DTDescrList". Problem was that the code to get
- the next node from a given node didn't expect that two nodes
- have the same name.
- Fixed.
-
- - ObtainDataTypeA: Fixed the memory loss of n * 40 bytes (e.g.
- loss of a iffparse.library IFFHandle).
- Thanks to Oliver Robers (oliver@poboxes.com) for reporting the bug.
- Fixed.
-
- - ObtainDataTypeA: Fixed a bug that an custom compatisation hook
- (e.g. the DTCD code in a descriptor) for IFF forats gets an
- IFFHandle and a file handle. Now only the IFFHandle is given, the
- file handle is NULL (because iffparse.library manages the file
- handle).
- Fixed.
-
- - ObtainDataTypeA: The clipboard did not work with masks longer
- than 64 bytes.
- Fixed.
-
- - Increased the stack size of the async layout process from 8192
- up to 16384 bytes. Should be __really__ enougth now.
-
- - Changed the behaviour of DoAsyncLayout:
- Previously, the DTSIF_LAYOUT flag was used to indicate that a
- layout process is running.
- Now the DTA_LayoutProc attribute is always checked.
- The "normal" Forbid / Permit protection of async layout process
- creation / signalling / deletion has been replaced by an
- internal datatypes.library semaphore.
-
- - Increased the stack size of the printer process. Should be
- __really__ enougth now.
-
- Features:
- - Fully backwards compatible: The datatypes.library V45 has the same interface as V40/V39,
- old applications won't have problems with this update.
-
- - Speed. The new datatypes.library is a little bit faster than the original. On request,
- a 020-version wouuld be possible.
-
- - Bug-Fixes: datatypes.library V45 fixes all bugs I knew about the datatypes.library V40.6.
-
- - Extended interface:
- The new datatypes.library introduces new features in the datatypes system:
- - Tools: You can define a set of tools for each datatype.
- A DT browser like "GMultiView" is able to present the list of tools in a
- menu/dock/etc., and is able to launch them.
-
- For example, you're viewing a C source, you're able to launch CED from the
- tools menu.
-
- - Image: The datatypes.library V45 includes the docs how to handle a datatype
- like an image within applications and/or other subclasses.
-
- - Descriptor list: Applications are now able to access the datatypes global descriptor
- list in a system-friedly way.
-
- - AREXX interface: A backwards-compatible and extended interface
-
- Many other features have been added to make things using datatypes easier.

- Following was cut from an aminet "weekly-uploads" mail:
- | Please rate all the programs you

- | RATE <path> <num>
- | where <path> is the file you want to judge and <num> is a mark from 0..10
- | with 10 being the best. You can rate several programs in one mail, but
- | don't rate your own programs. Example: RATE dev/gui/mui23usr.lha 8
