wxperl-users — For wxPerl users

[wxperl-users] wxPerl on Mac OS X

[Matt F. <ma...@iw...>]

Hi everyone.

I know there have been plenty of e-mails regarding this, and stupidly, I ignored them because I never thought I'd be working on a mac. Now, I have an iBook and I'm kicking myself for not paying attention to those e-mails.

So...what's the deal? Is there wxPerl for OS X? Do I have to build it myself? etc..

Thanks,
Matt

[wxperl-users] Re:fork/threads

[<rug...@ya...>]

Hi Marco, 
I try to use fork() under windows NT but my
application always crash!
Under Linux the same application works well.
I tink that is a problem of the system and it's
immposible to resolve.

I hope in a version of perl with thrads like java.

Ciao

[wxperl-users] wxPerl && fork/threads

[Marco T. <wx...@so...>]

hy all,

i'm trying to write a programm that downloads something...
let's say:

      for($i=1; $i<=100; $i++)
      {
            $this->{gauge}->SetValue($i);
            sleep(5);
      }

problem:
this freezes my gui...

my proposed solution:

my $pid  = fork;
if ($pid == 0)
{
      for($i=1; $i<=100; $i++)
      {
            $this->{gauge}->SetValue($i);
            sleep(5);
      }
      exit(0);
}

ok, gui doesn't freeze anymore...
but the program crashes around exit(0)

so, can anyone explain me how i can prevent my gui from freezing?
how to use fork()? what i'm doing/thinking wrong?

should be os indepent...

currently working with: wxPerl0.08 & ActivePerl 5.6.1.631

greetings
Marco

PS: i already asked something related to this topic but haven't found a
solution

RE: [wxperl-users] bug in wxGauge ?

[James L. <ja...@mi...>]

Hi Marco,
This is, apparently, a 'feature' in the progress bar control under
Windows (I assume that by 'gauge', you mean the progress bar).  The
maximum range or value is 65535 or so, and so setting the value above
this causes the gauge to show 100%.

I posted something on the wxWindows group about this, and Mattia and
others responded; I am not sure if there is a wxWindows or wxPerl fix
available yet, but there is an
easy workaround.

The workaround I used was to set the range to 100, for example (it could
be higher if you want greater granularity), and then set the value to a
proportion of this as the value you want to show increases. =20

i.e. something like:

$this->{gauge}->SetRange(5000);
.
.
.

my $nGauge_value =3D $nValue/5000;
$this->{gauge}->SetValue($nGauge_value);
.
.
.

I believe that this is how the fix to wxWindows will be done (i.e. the
actual range and value will be limited internally), in the Windows
implementation.  However, I'm not sure if this has been implemented yet.
Mattia will know, I think.

That sounds good. Pls let me know if it compiles with mingw.
I do not have VC++. I compiled wx with mingw.

Btw, is it easy to compile wxperl, or do you need inside tweaking
knowledge :-) ?

I just got the PPM last time. So I mean, is there a makefile which will
create the PPM?

Mattia (or anybody else in the know),

You said the taskbar was in CVS. Can I test it already, or is it only
part done?

I have an application in which the taskbar plays a major role because
it runs mostly in the background. If it's working, and you have a line
of sample code, I'd like to give it a try.

Btw, is wx 2.3 necessary?

I think it is a Perl bug: putting an (empty) DESTROY in Wx::PlVlaidator make it 
disappear.
The strange thing is that base classes do not have DESTROY methods
( so it can't be the empty one masking a base class' DESTROY ),
but if you put UNIVERSAL::can( $_[0], 'SUPER::DESTROY' ); in the
previously empty DESTROY {}, this triggers the error.

What about Wx::Pl::someclass - the Pl indicates that it is implemented

Good point.  I think I'll use the 'flag' approach.  This has approach
has been used elsewhere (in Win32::API, I think), so I'll try to be
consistent with other modules.

the trouble is that in perl you can only have scalar references,
so you need a flag to tell the class you want a number/string/bool
transferred

the one I wrote in C++ a year ago could:
* check that the number is aproper integer number
  ( if you passed a int/long pointer )
* check that the number is a proper float number
  ( if you passed a float/double pointer )
* optionally check that the number is in some

No, there aren't yet; wxPython puts user contributions in
wxPython.lib, but Python has a nice feature that lets you do
from wxPython.lib import fooclass ( or something like this ),
and the use fooclass withour qualification. I'd like
to have the Wx:: prefix ( same CPAN dir ), so,
Wx::lib::someclass, or Wx::extra::someclass, or
Wx::Plsomeclass are all valid choices.

Yes, I think a Perl-implemented GenericValidator can just take the
address of the variable to/from which to deposit/get data, and can
handle it appropriately internally by checking the reference type.

What would you like it to do?  Take a mask and validate the input
according to the mask?  (I'm assuming there's no existing wx masked text
control already).

Hmm... Have looked at the C++ code for the GV, and see what you mean
with comboboxes. =20

Just trying to work out how we can differentiate between setting
selection by index or string. In this case, I think we need a separate
ComboBoxValidator (or rather ChoiceValidator), with a flag passed to the
constructor indicating how we want to set the selection (index or
string).

In the light of this, do you think we should not have a GV, but have
individual ones for each control type, or implement the GV in Perl with
more intelligence?

> But since I do not use validator that much, it's up to you to decide
Oh goody!

In terms of package/object naming, what should I do?  Not sure if the
Perl validators should be in the Wx namespace.  Notwithstanding that, I
think I should name the validators PlGenericValidator, PlChoiceValidator
etc., to differentiate from the 'native' wx validators.  What do you
think?  I don't know if there are standards already published on this in
the Wx/Perl community.

wxTextValidator is OK for Perl, while wxGenericValidator does
1 - use overloading
    wxGV construtor takes one of a int/bool/string/integer array
    (C++) pointer ( think Perl references ), but in Perl
    int/string/bool map to scalar.
2 - there is no NumericValidator ( or whatever you want to call it )
    one that does a text->number conversion with error
    checking/bound checking, for intehers and floats
3 - I don't like wxGV because it tries to do
    validation for all controls, doing the Right Thing, but this
    sometimes is not possible ( like: for comboboxes
    if you pass a string, it returns the selected string,
    if you pass an integer it returns the index of the selected string in
    the combobox, but if I want the selected string as a number
    ( because my combobox contains, say, 1,2,3,4,6,12 ) I need
    a custom validator ( this relates to the lack of a NumericValidator )

Dear Mattia,

I was so close... Anyway, now I'm up and running.

I had noticed the 'Attempt to free unreferenced...' error - will await a
fix.

Now that I've got things working, what do you suggest/would you like?  I
feel that validators are the way to go when it comes to transferring
data to/from controls (rather than explicit GetValue/SetValue calls all
over the place) - I have had to implement a similar concept (though not
as elegant) in a very large Perl/Tk application which we have developed.

I see that you think we should create Perl versions of
wxGenericValidator and wxTextValidator - I am happy to do this and
contribute them to the project.  If I do this, do you (or anyone else on
the list) have ideas on how we should name/implement them?  What 'better
interface' can you envisage for a Perl-based Validator?  I have not
examined the native wxGenericValidator and wxTextValidator yet, so am
interested in your thoughts.

Here is your example ( modified minimal sample, use Help->About to
show the validator dialog )

I am getting a "Attempt to free unreferenced scalar at 
C:/Developement/wxPerl/wxPerl/blib/lib/Wx.pm line 61.", 
which I was not getting when I first tested Validators.
It is obviously something I am doing wrong with reference
counting in wxPerl; will fix.

A caveat: do not use a validator after you did
->SetValidator(); for implementation reasons,
once you do ->SetValidator() it is no more valid.

RE: [wxperl-users] Re: wxValidator available via wxPerl

[James L. <ja...@mo...>]

Dear Mattia (or others, if they can help),
I've been delving into how to use wxValidators, and I think I understand the
concept (and I like it!).

However, I'm having real trouble deriving my own validator (called,
unimaginitively, myValidator) from Wx::PlValidator.

>From the wxWindows documentation, all validators must implement a Clone
method.  I have tried implementing a Clone method, which I can see getting
called, but myValidator's Validate, TransferFromWindow, and TransferToWindow
never seem to get called.

Here is my code (with the methods apart from Clone doing nothing useful
apart from printing to STDOUT):

VVVVVVVVVVVVVVVVVVVV
use Wx;

package myValidator;

use vars qw(@ISA); @ISA = qw(Wx::PlValidator);

sub new {
 my $class = shift;
 my $this = $class->SUPER::new();

    return $this;
}

# see the docs for the three following functions
sub TransferFromWindow {

    print "TransferFromWindow called\n";
    return 1;
}

sub TransferToWindow {

    print "TransferToWindow called\n";
    return 1;

}

sub Validate {

    print "Validate called\n";

    return 1;
}

sub Clone {

    my $this= shift;
    print "Clone called\n";

    # clone by creating a new object, which should, in the real class, have
copies of all
    # properties of $this

    # could/should we use something like Storable::dclone here??

    my $tmp = myValidator->new;
    return $tmp;

}
1;

^^^^^^^^^^^^

A code snip from my main program, where I'm trying to test the validator,
looks like this:

vvvvvvvvvvvvvvvvvv
    # add wxValidator for the raw text, using the getter generated by
wxDesigner
    my $objText = $this->txtRaw;

    my $sText = 'Hello';

    # note that the constructor for myValidator does nothing with arguments
yet
    my $vldTmp = myValidator->new(0,\$sText);

    $objText->SetValidator($vldTmp);

    # various attempts to get the validator to kick in!
    $this->TransferDataToWindow();
    $this->TransferDataFromWindow();
    $objText->Validate();
^^^^^^^^^

However, I do not see the validator's methods being invoked.

Could you post a very simple example of how to create a validator class in
Perl, and how to create a frame which uses it, please?

Thanks a lot,
