[wxperl-users] wxPerl 0.12 - STC error (CVS 06/10/2002)

[Graciliano M. P. \(V. Sites\) <gm...@vi...>]

Mattia,

  I got the wxPerl CVS on 06/10/2002, and STC doesn't compile with VC++ =
6 and wxWindows 2.3.3 on Win32!!!

  The problem is with the link cmd!

Got it; I really don't know why it worked before, but now
it should work because the code is correct ;-)
(fix committed to CVS).

I can't reproduce it neither in wxGTK nor in wxMSW
with current CVS. Under MSW 0.11 is fine. I haven't
tried 0.12b2 yet (will do). Under which platform did it crash?

[Graciliano M. P. \(V. Sites\) <gm...@vi...>]

I was looking for I/O redirection of a process for Wx. I saw in the wxPerl
demo something for that, but doen't work!

I got this alert on reading the HANDLE:
readline() on unopened filehandle o at
F:/CVS/wxPerl/wxPerl/demo/wxProcess.pm li

I'm using Win2K, Perl580 and wxPerl-0.11-wx233. I made another script to
test this:

---------------

#!/usr/bin/perl

use Wx ;

package MyApp ;

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

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

sub OnInit { 1 }

package main ;

 my $app = MyApp->new() ;

 my $process = Wx::Process->new( $app , -1 );
 $process->Redirect ;

 Wx::ExecuteArgs( [$^X, "test3.pl"], 1 , $process );
# Wx::ExecuteCommand( "$^X test3.pl" , 1 , undef ) ;

 my $stream = $process->GetInputStream ;

 while( 1 ) {

The GTK version one in Debian 3.0. wxGTK is statically linkes, hence you

If it was Wx::ComboBox, this was a wxPerl (not wxWindows) problem,
and it is solved in wxPerl 0.12b2.

I am afraid that this is the only answer: there were just too many changes
from wxWindows 2.2.9 to 2.3.x.

I am afraid this does not help...

For item labels you can use EVT_END_LABEL_EDIT and compare the label with
the old one (that you need to save in the EVT_BEGIN_LABEL_EDIT handler).

Is one project, for Perl too, that I have. I haven't published it to the

Well, I can post to P5P, but I can't wait for them to start what I want to
do! And they released Perl-5.8 now, we will need to wait another release to
see it there. And Perl 5.6.1, what the peoples really use for now, will be
in the place of Perl-5.8 during a long time, since Perl-5.8 still need to
fix some bugs.

HWX will have a HWXeditor. This is my goal, but first it need the base, GML.

The idea of the debuger is great! You can co-ordenate this.

Man! If an end user get some HWX app, it need some interpreter to run it! It
can get Perl and configure it to run HWX apps, or just get HWXperl.

Make some tests with GML, controling the objects, and you will see that
DotRef is very usefull!!!
DotRef for the GML objects, work like javascript with objects of a <form>.
If you don't use DotRef you always need
to have the variable of the object. Since who create the objects is the GML
parse & contructor, where you get this variables? You can get from
$HWX::OBJ{id}{idname}, but with DotRef is just: obj.id.idname.Show(1)

But, how I always say, and Perl too, you are free to do what you want, I
never cut anything!

Well, I can't wait for Perl6! Perl6 have a long long way until be a stable
thing! Of course, when Perl6 comes, I will port HWX to parrot! And you use
the dots...

Yes, PerlBin enable this. But I prefer to delivery HWXperl. If you think,
compile and send your won perl/lib with the app is not different to send
HWXperl, since the bigger part of HWXperl is the GUI lib, and you always
need to delivery the GUI lib. Delivering HWXperl any other HWX app are free
to work on this machine, and the app will be very very small, only some
Kbytes! Use less Kbytes is good for pockets PCs, since they have less
memory. Just imagine, you install HWXperl with 15Mb, and you can have 150
apps with 100Kb (total 30mb)! without HWX you have less than 30 apps.

I say again, the developer are free to do what it want! Your idea to use any
Perl to run HWX apps was inside the HWX project from the begining. But I
don't like the idea to cut off resource just because they don't work in the
standart Perl, and this is why I created HWXperl!

This is what the HWX enverioment will have, and much more. I have a lot of
ideas to implement over HWX, one of them is to create a repository of HWX
apps and a browser to install them. Just imagine, you chose the app, click,
some Kbytes later it's runing in you machine, no metters what OS you are
using. This is good for the user, small and good apps, and for the
developer, it don't need to rewrite or compile for each OS.

I still want you in the project, since what you think that we disagree are
inside HWX too, they just aren't my top choice! I just don't like the idea
to make 2 GUI design tool! Why not just make the HWXeditor. The editor will
work on HWXperl or not, since you can delivery it like any other app with
PerlBin, and you will have more peoples to work with you.

About DotRef, I can make a Filter for DotRef that works without the changes
of toke.c. It will have less resources, but will enable HWX apps in other
Perls.

What I think that you don't like is to be dependent of HWXperl to run the
apps. HWXperl was not to make the peoples dependent, is to already have
something done to run the apps, like ActivePerl for Win32. The peoples can
get standart Perl and compile, but they don't do, they get AtivePerl. All
the modules will run in any Perl, the peoples can install them, or just get
HWXperl, the choice will be from the developers, how their apps will be
delivered, using HWX enverioment, or just like a Perl script, or a binary
with Perl/lib.

[wxperl-users] wxTreeCtrl change flag

[Alejandro F. <af...@st...>]

Hi,
i am making an accounting report tool with wxTreeCtrl.

In the script you can save a project, reopen it, change it, save it =
again, etc.
I want to add an dialog when the user exits the script that gives him a =
warning if the tree has changed without saving.

The question is if i have a kind of event related to TreeCtrl that =
triggers when a change in item/tree attributes occurs and that can help =
me set a 'changes occured' flag.

Regards, Alejandro.

If by "layout" you mean "keyboard layout", then be aware that locale
has nothing to do with keyboard layout. If you did not mean "keyboard layout",
then just forget what I just wrote...

from the wxWindows documentation for wxTextCtrl

wxTE_RICH
Use rich text control under Win32, this allows to have more than 64Kb of text in the control even
under Win9x. This style is ignored under other platforms.

hello all,
i played with the Wx::Locale::GetFontEncoding implemented in wxPerl 0.12

i'm a little bit confused about linux.
i always get iso-8859-15, no mather which layout i enable...

i attached a little script that checks which encoding is on the system.
i would rally apprechiate it if the users of the 0.12 wxPerl could test
it and tell me what they get (linux and windows)
would relly be great if i get some feedback

Well, I think it is worrying... Now, do you have some sample code that triggers it?
does it happen even with the 0.12b2 snapshot? Do you actually have a Wx/Bitmap.pm
(which maybe comes from an older installation)? 0.12b2 hasn't a Wx/Bitmap.pm,
hence I _think_ maybe you have an older one, and saying "use Wx::Bitmap" loads it
and causes problems.

Re: [wxperl-users] use Wx::Bitmap; funks things up ~ bizzare

You don't have to 'use Wx::Bitmap' to use the Wx::Bitmap->new(). Just 'use Wx qw(:everything). That will suffice.
