why don´t you help a development of hbqt, seems a good api (multiplataform),
and you can make include files in a hwgui format
Thanks

Assunto: [Harbour] Singleton Design Pattern in harbour objects
Hi,
My name is Leandro Damasio and I have started to
follow Harbour Project Main Developer List few days ago. I recently started 2D
Informatica with my associate Ted, to develop commercial aplications using
[x]Harbour. We used xHarbour + BCC55 + HWGUI for about 3 years, until we read
xhb-diff.txt document and decided to try Harbour instead.
We are about to realease 2DWGUI, an Object Oriented
Harbour API to Win32 GUI, and its going to be a free product but not opensource
from start.
Our experience with opensource development is
minimal, but I believe we could be useful by giving sugestions and/or reporting
problems at least.
My first try:
Does harbour have native support to singleton
classes? Its an useful design pattern to declare unique instance objects, so
the
same instance is reacheable/accessible globally by just calling for the the
class name.
We implemented Singleton objects in xHarbour,
but I'm sure the native implementation should be done better by someone who
knows the object machine inside.
The Singleton Class usage is like
below:
<code>
CLASS Aplication SINGLETON
DATA Status
METHOD
Init(aParams)
METHOD Run()
METHOD End()
ENDCLASS
Procedure Main (...)
Aplication():Init(hb_aParams())
Func2()
Aplication():End()
Return
Static Function Func2()
Aplication():Run()
Return Aplication():Status
</code>
If it is not implemented yet, do you think its a
good idea to implement natively?
Thanks
Leandro Damasio
