Version 2 is uploaded:

Added additional support for <i>hrb</i> updates. An update module is 
included in <i>testhrb.prg</i>, it allows to get new <i>hrb</i> files 
from my site.
   Besides, a problem solved, related to some Android feature - it 
doesn't close an application after closing a main window (Activity).

Yes, I have wrote this on my site:
"One of menu items may implement the program update - and copy a new 
testhrb.hrb from some server for using instead of that one, which is in 
apk."

  Now at the start of a program the testhrb.hrb is copied from the apk's 
asset/ to the application home directory if it is absent there. It isn't 
difficult to write a function in testhrb.prg, which reads an updated 
testhrb.hrb from some server, using hb_inet... functions or letodb file 
functions and put it in that home directory instead of existing.

  I've posted it to the harbour-devel, but it seems that the list

  Not everything. Java and C sources are already compiled, we need to 
build apk only. If needed, the Java or C code may be recompiled using 
the bat files in h4a/directory.

   Yes. Editing the testhrb.prg we may include there as much functions 
as it needed.

   Yes. We need to carefully consider the whole structure and details of

[Francesco P. <fpe...@gm...>]

Hi Alexander,
thank you for this post. I think you should cross-post to harbour-users and
also qtcontribs.

Let's see if I understand what you did:

A command-line based setup to:
  - compile harbour sources to HRB
  - create the apk
  - install the apk on the device

This means that we:
  - are not forced to use Qt Creator or other GUI tool....
  - are not forced to create a library from the prg code

When the program built with your system runs on Android:
  - it copies the hrb file from assets
  - it loads it
  - it runs it
(it may be that we just copy the hrb without rebuilding everything??????? I
could not understand from the sources)

I didn't understand every steps of the running program, but it actually
shows the returned string values of 3 functions, 2 of which uses letodb.

It is a real Android executable and it seems that for full mix between
Android and Harbour we should write some glue functions.

Actually this is not for hbQt development, but I think that it may be added.

Thanks

[Hwgui-developers] Harbour and Adnroid

[Alexander S.K. <al...@be...>]

Hi All,

  recently I started experimenting with Android and have created a small 
demo application. It allows to write your own simple application - just 
edit the prg source file and rebuild the apk, Some details and an 
application package - at http://www.kresin.ru/en/h4a.html

Now I think over possibility to create Android GUI components from 
Harbour code - something like Android GUI farmework for Harbour.

[Hwgui-developers] Navigation Button, ButtonEx

[Itamar M. L. J. L. <ita...@gm...>]

Hi Alexander!
Using Hwgui 2.17 is possible pass of focus between Buttons or ButtonEx
using LEFT, RIGHT, UP, DOWN key but with version 2.19 not possible, only
using TAB key.
The focus of Buttons not accept keys of moviment, only TAB, you can fix
this ?

This version 2.19 is using the mouse excessively.

Itamar M. Lins Jr.

  Two years have passed, but for now this is HB_ANSITOOEM, which  presents
in both Harbour and xHarbour. Win_ANSITOOEM is in contrib/hbwin, but HwGUI
cannot be based on contrib code.
  Anyway, I added the Win_ANSITOOEM to printdos.prg and rename it to
hwg_Win_ANSITOOEM to resolve this issue.

Regards, Alexander.

   What is 3.4 ? 3.2 is the last version in Harbour's github repository. 
If you mean Victor's fork - maybe, there is some other #define value, 
which identifies it ?

I'm compiler use harbour 3.4 and no 'hb_ansitooem()' and be change to
'win_ansitooem()'.

   Why ? I saw the Harbour 2.1 and Harbour 3.2 - hb_Ansitooem() is 
defined in both.
   It compiles well under 3.2, which I use now.

Hello Itamar,
studying the hbrowser.prg, I saw that it has to this class should, at some

such implementation can be implemented in HCustomWindow derived class,
because there that was created :: bDestroy, the method :: End () could be
implemented performing this block

Made the implementation of the code in hcwindow.prg at line 191, ran beauty

  No, the CLIPPER flag is not intended for ENTER key to bahave like a 
TAB, it emulates console ( Clipper/Harbour ) GET system behaviour:
  ENTER and DOWN,UP are used for navigation between GET objects. The 
button isn't a GET object, so these keys doesn't set focus on it.

  The TAB behaves as it should in winapi - navigates between all 
controls, which has the WS_TABSTOP style.
