Hi Fernando
Thank you for the invitation! Hbqt seems really very interesting project. Of
course I would like to help if I could or when I can, but I have to learn more
about how it works first.
My current commercial focus and programming background are based on Windows. I
just didn't ever hear about QT or wxWidgets until some days ago and I got very
glad to know such powerfull crossplataform solutions for harbour as wxHarbour
and hbqt. I've been studing both.
Now our aplications at 2DInfo are been changed from xHarbour to Harbour and
from hwGUI to 2DWGUI and once we finish this work, crossplataform funcionality
is going to be the next step and then I hope we will be ready to participate
more activelly.
Best Regards
Leandro Damasio

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
