[Hbasic-userinfo] confusion in database manager ++

[Kim L. <ki...@it...>]

The Database manger dialog seems a bit confused about
hbdbname an dbname.
the dbname entry will always be sett to the hbdbname.

anyway attached is a patch for it + a minor patch for a tr( to QObject::tr( in 
src/global_commands.cpp that the compiler complained about

There also seems to be somthing strange with the build system, the QTLIB entry 
in Makefile.global is empty after a configure, it should be -lqt-mt...

A ran this on a RH9.0 with the latest qt/kde compiled via konstruct, i have 
both qt and kde in /opt/kde so...

Configure line for HBasic:
./configure --with-compiler --with-kdeui --with-x \
 --with-qt-libraries=/opt/kde/lib --with-qt-includes=/opt/kde/include \
 --with-kde-libraries=/opt/kde/lib

[Hbasic-userinfo] New version 0.9.8h released

[<mar...@t-...>]

New feature for classes which are derived from Qt class. If QTC support 
has been activated the public methods of the appropriate Qt class may be 
called for the HBasic class instance. If you have for example created a 
Button widget in the formdesigner you normally may only call the methods 
which have been defined as a SLOT in the Qt C++ source code. With the 
new version and activated Qtc support you may also call the public 
methods of the QPushButton base class. A detailed docu for this feature 
will follow later.

[Hbasic-userinfo] New version 0.9.8g released

[<mar...@t-...>]

New version 0.9.8g released. Bugfixes in component selection in 
formdesigner. Components may be created with parameters of type 
component now. See code_examples/components/listview.bas as example 
program. Some bugfixes in QTC support.

[Hbasic-userinfo] Bug in HBasic-0.9.8f

[Holger K. <hol...@mu...>]

Hallo,
I thing i have found a bug in HBASIC 0.9.8f

Holger

[Hbasic-userinfo] New version 0.9.8e released

[<mar...@t-...>]

New menu-editor may be used to edit menubars and entries in the 
formdesigner window. You may search for action handler subroutines for a 
menu/toolbarentry or create new ones in the menu editor functions. You 
may find the action handler with a double click on the action name. In 
the same way a double click on a component in the formdesigner will try 
to find the appropriate action handler in the source code before 
creating a new one if none exists.

The menu/toolbar of a MDI mainwindow may be created or changed in a 
special form window which has been added to the project windows. The 
compiler to create standalone executables may be activated with a

configure --with-compiler

but there are some updates required before it is on the same level as 
the interpreter.

AW: [Hbasic-userinfo] Compilation Error

[Engels, M. <Mar...@SP...>]

Hello Mohammed,

I am not shure why the compiler cannot find the include file memory.h =
which
is required to find the class MemoryBlock. I have appended a modified
version of the file parser_memory.cpp. Please try to put this file in =
the
parser subdirectory of the HBasic sourcedir and restart the make =
command. If
it fails again send me the output of the gcc command which will be =
executed.

I also had to put a new version 0.9.8f in the internet where I have =
fixed
another bug which doesn't occure on my system. Therefore the best way =
would
be to download the 0.9.8f version, replace the file =
parser/parser_memory.cpp
and recompile all files.

Marcus Engels

Betreff: [Hbasic-userinfo] Compilation Error


Hello,
I tried to compile the HBasic 0.9.8e package and it
there is a compilation error with the parser_memory.h
and parser_memory.cpp

I tried to do this on Mandrake Linux 9.0 (I don't
remember the gcc version at the moment but I think
it's gcc 3.1 or 3.2). I also attached the error output
in a file with this message.

[Hbasic-userinfo] problem running hbasic after installation

[<se...@ch...>]

Hello,

I've compiled the source code and needed library's but when i try to run it, 
it gives an error:
{
/usr/local/hbasic/packages/hbasic_hbobject_1.so: undefined symbol: _Znwj
}

does any one know how to solve this problem?

[Hbasic-userinfo] compiler?

[<noe...@sk...>]

hi,
I just downloaded HBasic 0.9.8c and compiled it on redhat 9.0.
Just one small question: how can I compile my .bas programs to create 
standalone executables?

[Hbasic-userinfo] problem with db widget properties

[Kim L. <ki...@ki...>]

1. OS: RH 9.0 
    qt-3.1.2 and KDE 3.1.2 compiled from source 

   configure line:
  ./configure --with-compiler --with-kdeui --with-x \
   --with-qt-libraries=/opt/kde/lib -with-qt-includes=/opt/kde/include \
   --with-kde-includes=/opt/kde/include --with-kde-libraries=/opt/kde/lib

This resulted in some minor complitation buggs in:
./lib_calc_sheet/sheet_editor.cpp
./src/global_commands.cpp
./src/main.cpp

Where is hadd to insert a #include <kapplication.h>
After that everyting compiled smothly and starts up ok but:

there is a problem with property handling in the db widgets that leads to a 
segfault:

1. Use database conections to add a mysql database to the project, this works 
ok and i can open tables etc.
2. Use Package manager to add the hbasic_dbaccess package, the widgets are 
added to the "components window"
3. Add a Db_Form widget
4. Add a ColEdit  widget.
5. Try to set the th DB_COLUMN property of the ColEdit -> crash!

Now

The crash only manifests if there is a Db_Form widget already present.

[Hbasic-userinfo] HBasic Bugs and Ideas

[<mep...@we...>]

Hello, 
the first thing I've discovered  about hbasic 0.9.8c is the menu Window is extremly broken. 
Every submenu underneath Property Editor  returns an exception when chosen and the program 
is oborted. 
 
2nd what do you think about implementing a treeview e.g. a directory-treeview as new 
component in the componenteditor ? 
 
3rd would be nice to have a submenu within 'Run' to make an executeable. 
 
4th should be possible to delete components from a form by marking it  and pressing "Del". 
 
5th Despite of these issues it looks very promissing what you do. Go on :) 
 
Best regards

[Hbasic-userinfo] Crashes in HBasic

[Volker S. <li...@in...>]

Hi,

I'm using Mandrake 9.1 and HBasic 0.9.8c compiled unter Celeron-Notebook.
HBasic configures, compiles etc. without any errors.

Starting HBasic with the default project I just type some stuff into the code-window and then using the mouse to select something. Now I press the 'Back' button to delete the selected part and HBasic freezes. After about 10 seconds it terminates. In the console I find this:

It is impossible to create a programm, because always those crashes while editing.

And a wish: If I DoublKlick a control, HBasic always creates a new sub for the Click-Event, even if this sub is allready existing. If the sub is existing, HBasic should only jump to the existing event. Now, the new sub has to be deleted everytime.

Now I wanted to test this and after folding the second Click-Event in the code-editor, HBasic say'd he has a segmentation fault. After this i find in the console:

[Hbasic-userinfo] Compile problems with exec functions

[<mar...@t-...>]

If you get a compilation error in the file query_designer.cpp in version 
0.9.8c the problem might be the difference between the exec method call 
in Qt 3.0 which requires a QString parameter and exec in Qt >= 3.1 which 
doesn't allow a QString parameter. I have appended a new version of this 
file to the mail where I tried to fix the problem.

Try to replace the file gui_db_access/query_designer.cpp with this file 
and restart make and make install.

[Hbasic-userinfo] New version 0.9.8c released

[<mar...@t-...>]

This version has a major bugfix in the sourcecode editor, a new undo 
history which may store the last 10 modifications, cut copy paste 
functions for widgets in the formdesigner and some more undo functions 
for components in formdesigner (e.g. for aligning and inserting new 
components).

[Kannan R. <kan...@ya...>]

Regards and best wishes to all the hbasic users and a
mailing list like has been long time coming.

Hope we grow from strength to strength. Meanwhile Im
testing the other basic environments as well under
Linux.

I hav RH 8.0 and Qt 3.11, tried and ended with couple
of errors. But the features are quite promising.

Thanks to all,

[Hbasic-userinfo] Setting up methods for HBasic

[<mar...@t-...>]

Hi Ahmad,

updating the function library is an good idea. This functions will be 
implemented in C or C++ so that you should have no problems. 
Implementing functions requires two different steps.

1) Create a function definition in C or C++ within a HBasic package 
description. I have put all functions in the hbasic_stdgui.so packages 
which will always be loaded on startup of HBasic but you may also copy 
this package and create your own if you like.

2) Since compiling the C functions to a library only gives me some 
machine language code with an entry point for the function HBasic needs 
some additional information about the number of parameters, the return 
type of the method and the type of the parameter values. For popup 
info's I have added some additional description line and the name of the 
parameters will also be stored in this information. This info files 
(called <package_name.dso>) will be created with the libdesc program 
which will also be installed with HBasic.

Let me give you an example. If you take a look at the file 
<HBASICDIR>/packages/hbasic_stdgui/hbasic_stdgui.cpp you will find the 
method definitions for functions like

double fn_sin( double d )
{
      return( sin( d ));
}

This is the method which HBasic calls whenever the parser finds a sin(d) 
method call in the HBasic program. I first also tried to call this C 
function sin() but some compilers got into trouble with this naming so I 
have renamed them to fn_sin() ...

Let's try to insert a new method which will multiply a double number 
with 2.0. Insert some code like

double mult2( double par1 )
{
     return( par1 * 2.0 );
}

into the hbasic_stdgui.cpp file and run make and make install. This 
should compile the new library and copy it to 
/usr/local/hbasic/packages. The *.so file is the library which will be 
loaded as a shared library by HBasic and the *.dso is the current 
version of the description file needed by HBasic.

For the second step we have to start the libdesc program (Sourcecode in 
libdesc subdirectory). Click on Menu "Load/Load description" and select 
the hbasic_stdgui_1.dso file from the /usr/local/hbasic/packages 
directory.  You should now see a list of the components, constants and 
methods that have been implemented in the hbasic_stdgui package. We want 
to add a new method description so click on the "Method list" folder 
with the right mouse button and select "Add method". In the dialog that 
pop's up you should fill in the following fields:

1) Method name is the name that should be used in HBasic to call the 
method. We could call this "multiply_two" (or whatever you like) for our 
example.
2) Symbol to call is the name of the symbol that the compiler has 
generated for the object code of the C function implementation. For C 
code this is the same as the name in the C sourcecode but for C++ code 
this is a little bit more complicated. I normally use something like

objdump -T /usr/local/hbasic/packages/hbasic_stdgui_1.dso | grep mult2

to find the name of the object symbol. You may also click on the S 
button on the right side of the editline for the symbol. This will also 
list the symbols in the library in a new dialog. Type mult2 as a search 
string in the editline and select the symbol which is _Z8fn_mult2d for 
my gcc-3.2 compiler.

3)  Select "double" as return type
4)  Select "double" as parameter type, give a name to the parameter and 
click on add to add the parameter description to the list below.  You 
may also add a short one line method description for each method which 
will be displayed in the editor of the HBasic IDE.

If you save this description it should now be possible to use this 
method in HBasic sourcecode.

Startup HBasic and insert a new button into the form. Doubleclick on the 
button and insert some example program like the following in the 
sourcecode editor:

Sub button1_clicked()
    Dim d As double

    d = 12.34
    print multiply_two( d )
End Sub

Running this program should display the result 24.68 on the form which 
means out method defined in C has been called.

Maybe I haven't mentioned all the methods that I have already defined in 
the hbasic_stdgui library in the documentation of HBasic. Some of the 
methods that you wanted to implement might already be in the library. 
Have a look at the method list after loading the library into the 
libdesc program to see the list of defined methods. Looking at the glibc 
documentation there will be some more functions that might be useful in 
HBasic so there is much to do and any help is welcome.

I hope the description helps you to set up new methods with HBasic. Send 
me some info if you have problems or further questions. To help other 
people I will also send this info to the HBasic mailing list that I have 
set up on sourceforge (hba...@li...).
