QtContribs - Harbour Qt Projects

Welcome to the new chapter in Harbour's history: Harbour Qt Projects.

So far all the contribution libraries were hosted in Harbour project's repository. This is the first time a part of it has been pulled and hosted outside. To make sure that end-user is not affected by this split, the folder structure of this repository has been kept the same as that of Harbour's. The same make system and the same build targets have been achieved.

As the name suggests, Qt related projects, viz., HbQt, HbXBP and HbIDE have been transferred here.

The goal of this project is be the satellite of Harbour Project, and not an independent project. This project will try to honor the high standards set forth by Harbour. It will encourage the developers to write code in such a way that Harbour could adopt and absorb inside its own repository, if the administrators deem fit.

This project will never attempt to develop its own build system and will ever rely on Harbour's native one. So if Harbour happens to make changes then maintainers of Harbour will be requested to update the same here also. As of now I have near zero understanding of Harbour's make system, and if that breaks for some reason, I will find it helpless to set it right for this project.

Everybody is encouraged to contribute to this repository. Do not be afraid of your creativity level, just have a willingness to contribute, respect Harbour's coding high standards, and send it here. Your small contribution will make HbQt bindings extremely rich.

In this repository we do not have, at times, hypothetical constraints. But it does not mean that we have to drift away from standards set forth by Harbour. We have to remain careful about the acceptability of our codebase. Constraints can be overlooked if changes do not harm the portability issues if a piece of code is supposed to be portable.

So, do join us...

Locking schemes used with DBF files by Przemyslaw Czerpak

Locking schemes used with DBF files.
Przemyslaw Czerpak (druzus/at/poczta.onet.pl)


Exclusive/shared modes (DENY READ, DENY WRITE) in POSIX systems.
================================================================

Exclusive modes (DENY READ, DENY WRITE) do not exist in POSIX systems.
They can be emulated by fcntl() or flock() locks. Harbour uses flock()
in systems where it does not create conflicts with fcntl() locks used
to synchronize file access by different processes in shared mode.
Currently it's enabled by default only in Linux (tests with *BSD systems
and MacOSX showed that it interacts with fcntl locks causing deadlocks).
On other POSIX systems Harbour uses fcntl() read and write locks at
address 0x7fffffff (size 1) to simulate shared and exclusive mode.

CLIP and FlagShip use fcntl() locks to simulate shared/exclusive modes.
CLIP shared/exclusive flag:     0x7fffffff : 1 (the same as Harbour)
FlagShip shared/exclusive flag: 0x7ffffbfc : 1




File access synchronization (record and file locking) in shared mode.
=====================================================================

FlagShip uses different record and index locking schemes
(i.e. for RLOCK it locks record area) and it is not described
here.


In documentation CLIP can use Clipper like or FoxPro like locking
schemes and it can be controlled by SET LOCKSTYLE [TO] ... command
or Set( _SET_LOCKSTYLE, 0 | 1 ) function.
This switch only changes the RLOCK/FLOCK offset.
For:
   SET LOCKSTYLE [TO] CLIPPER | CLIPPER50 | CLIPPER53
or:
   Set( _SET_LOCKSTYLE, 0 )
this offset is set to 1'000'000'000. This is header lock address
and records are locked at above address + record number.
This is compatible with standard Clipper locking.
Commands:
   SET LOCKSTYLE [TO] CLIPPER52 | FOXPRO | SIX
or:
   Set( _SET_LOCKSTYLE, 1 )
set this offset to 0x10000000 keeping the same algorithm
for record locking what is incompatible with any other locking
schemes known by me. For sure it's not compatible with [V]FP
locking (see details about this locking scheme below).
For more information look at CLIP source code.




(*) In Harbour index read locks are shared on platforms which support
    shared (read) locks.

Windows DLLs with Harbour code

There are a lot of infomation that can be gleaned if one chose to go through the \doc folder of any official harbour installation. In this post, I have chosen to re-publish the following:-


Windows DLLs with Harbour code

Programs created with Clipper or Harbour are traditionally a
monolithic EXE containing all executable code.  This includes
the Virtual Machine (VM) and the RunTime Library (RTL) as well as
your own code.  Running under Windows with Harbour, you
can now also create and use Windows DLLs that contain PRG code.

Harbour supports Windows DLLs in 3 ways.

  1) Self-contained DLLs containing functions from any platform.
     (These are not what we call a "harbour.dll", although they may
     be named that. The DLL entry points are different.)
     These have the VM/RTL inside them and can be used by any other
     Windows program. You can create a .lib for static linking,
     or use GetProcAddress as in any standard Windows DLL.
     Calling Harbour/Prg functions directly is limited to
     those that take no parameters unless you include C functions
     in the DLL that take parameters and then call the PRG-level
     code.

     To do static linking, do this to create the .lib:
        implib harbour.lib harbour.dll
     For the Borland C platform, use that library and import32.lib
     and cw32.lib from Borland, and you are ready to go.


  2) PCode EXEs using a Harbour.dll

     A Harbour.dll is designed to be called from a Harbour app.
     A pcode EXE is a small Harbour executable that does not contain the
     VM/RTL. To execute its functions, it must load and access a
     Harbour.dll.
     If you want dynamic linking, then use this to execute a Harbour
     dynamically loaded pcode DLL function or procedure:
        HB_DllDo( [,] ) --> []

     This lets you have all your common code in a DLL, and have lots
     of small EXEs that use it.  Realize however that, even though this
     may be a nice way to manage your code, each EXE may
     load its own image of the Harbour.dll into memory at runtime.
     In terms of Windows memory, there may not be a benefit to using pcode
     EXEs over monolithic EXEs. But it may be a worthwhile maintenance
     benefit to have lots of replaceable small exes.

  3) PCode DLLs used from traditional EXEs
     A pcode DLL does not contain the VM/RTL.
     It is a library of Harbour-compiled PRG code that uses the VM/RTL
     of the EXE that calls it.  This has the benefit of having
     replaceable modules in DLLs that don't necessarily require updating
     your EXE.


The following is clipped from a msg by Antonio Linares to the Harbour
developer list explaining some of the details:

Please notice that there are three different Windows DLL entry points:
   + src/vm/
   * maindll.c     Windows self-contained DLL entry point
   * maindllh.c    Windows Harbour DLL entry point  (harbour.dll)
   * maindllp.c    Windows pcode DLL entry point and VM/RTL routing functions

   >    * maindll.c     Windows self-contained DLL entry point
   To produce Harbour code, as DLLs, that may be used
   from other programming languages applications (as VB,
   Delphi, C++, etc...)

   >    * maindllh.c    Windows Harbour DLL entry point  (harbour.dll)
   To produce Harbour.dll, to be just used from small pcode Harbour EXEs

   >    * maindllp.c    Windows pcode DLL entry point and VM/RTL routing
   To produce small pcode DLLs, to be used just from Harbour EXE apps.
   maindllp.c is the entry point for the Harbour pcode DLLs. pcode DLLs
   are quite small DLLs, that just contain pcode and/or C (using extend
   api) functions.

   mainwin.c is the entry point for Windows EXEs, not for DLLs.

   You may use maindll.c, maindllh.c or maindllp.c based on
   your needs.

   If you are looking to build a Harbour.dll, then you must use
   maindllh.c

I will commit there from now on, if you're active dev member or admin and want to join, drop a message. Everybody else simply fork, patch and submit a pull request if you feel you have something to be included in main repo.

Instead of 'svn export', download source zip: http://github.com/harbour/core/archive/master.zip

Using HMG Extended 226 and hbDev32 on Windows 7/8

Brief Notes on Using HMG Extended 226 and HBDEv3.2 on Windows 7/8

1) When using HMG Extended, Harbour Dev 3.2 must be used to compile and link it via hbmk2.
2) Note that HBDev3.2 uses mingw as the default compiler and my hbp file would be as follows :-

-oPMS4hmgx
-w0
-gtgui
-rebuild
# Minigui libs
-lminigui -lvfw32 -lmsvfw32
//Harbour libs
-lhbct -lhbmzip -lminizip -lhbwin -lhbmisc -lxhb

# my apps hbc file
pms4hmgx.hbc

# list of prgs
PMS4WIN.PRG
LOCKS.PRG
RDDSYS.PRG

3) Add PATH=C:\HB32\BIN to your Environmental Variables in Win 7/8
