Yes, and this is enough for me (using the PPM):
C:\>perl -MWx -e "print Wx::wxVERSION_STRING(), qq{\n};$s
                  = Wx::GridSizer->new( 1, 2 ); $s->FitInside( )"
wxWindows 2.3.3
Usage: Wx::Sizer::FitInside(THIS, window) at -e line 1.

What does this print for you?

The "implemented class" part is not that difficult; the "implemented function"
part should be doable (automatically); which way should implemented/not
implemented classes/dunctions be marked?

> in wxPerl or not, what parameters wxPerl expects and so on.
If you could sketch some way to make parameter wxPerl expects,
or whatever, clearer, *and* if this can be made automatically
(i.e. by a script), I could incorporate this in the docs.

The second argument to AddBook needs to be a boolean (typically 0 or 1).

[wxperl-users] Wx::TreeCtrl::InsertItem fix

[Mattia B. <mb...@ds...>]

This is maily for Marcus, but might interest others.
There are two ways to workaround the bug you reported
(I suddenly realized that I did not explain the workaround, sorry)
1 - Call directly ->InsertItemPrev (if the 2nd argument is a
    Wx::TreeItemId) or ->InsertItemBef (if the 2nd argument is an
    integer)
2 - do this, after the "use Wx;"
    undef *Wx::TreeCtrl::InsertItem;
    *Wx::TreeCtrl::InsertItem = sub {
       my $this = shift;

       if( ref( $_[1] ) && $_[1]->isa( 'Wx::TreeItemId' ) )
         { return $this->InsertItemPrev( @_ ) }
       return $this->InsertItemBef( @_ );
    }

This is strange. I downloaded the binary ppm distro for Activestate 
Perl, which tells me it's built against wxWindows 2.3.3....shouldn't 
that be enough?

Not exactly. wxIE compiles and runs fine when built with MinGW GCC 3.1 (beta),
w32api from CVS, some patches to wxIE, and wxWindows is compiled statically
(MinGW GCC 3.1 has
some problems building wxWindows as a DLL, MinGW GCC 2.95 has some
COM-related bugs that prevent wxIE from working). This means that you need
to recompile wxWindows statically (don't pass the WXMAKINGDLL=1 parameter),
and compile wxPerl starting with "perl Makefile.PL --static"; note that
I did not test the --static flag under Win32, so it might not work.
At the moment it is probably better if you stick to Visual Studio.

Correct, this means that you can't do what you want, unfortunately.
You need to compile wxPerl wilt VS6 if you want to build wxIE with VS6.

No, the "THIS" the error refers to is the invocant
(i.e. the object you call the method on).

No, according to the help on wxHtmlHelpController::AddBook, it takes
two parameters, the path and a flag 
bool AddBook(const wxString& book, bool show_wait_msg)
adding the invocant (THIS), it makes three parameters.
   $help->Wx::HtmlHelpController::AddBook("./foo.zip", 1);
or $help->Wx::HtmlHelpController::AddBook("./foo.zip", 0);

> Anyway, the HTMLHelp in wx rocks. Far better than M$ HTML Help, imo.
IMHO the MS HTML help (aside from being Win32-only) is much better
than the wxWindows HTML help. But of course these are YHO and MHO,
and AHHOO (Anyone Has His Own Opinion) ;-)

yes and no.
if there's no wx way, that's what i'll do.

but the problem is that if there are 1000 listitems, and everyone needs
about 10ms to be created, a users would have to wait 10 seconds till
he see something if i put everything in an array first and sort it.

because of this it would be very useful if there's a wx way which handles=

These methods are recent additions (post wxWindows 2.3.2) you will need to
compile wxPerl against a CVS snapshot to get them. The binaries
downloadable from the bottom of the wxPerl download page have them, too.

You should be able to do that in wxWindows, but this is not wrapped
(yet) in wxPerl. It is now in the TODO.

That's a very usable list of workarounds and bugs. I am compiling a list 
of what I'm running into while developing the wxPerl version of pVoice 
myself. The idea I had was to setup a little site (wiki or something) 
with complete documentation of everything I'm using and all expierences 
(things that don't work and possible workarounds).

I'll make a start for this soon and would like to invite everyone to 
contribute. My experience is that the wxWindows docs themselves are not 
quite what you're looking for while building a wxPerl application, 
because it's not always clear wether a function or class is implemented 
in wxPerl or not, what parameters wxPerl expects and so on.

I've been working on a larger app for the past few months and I've
found wxPerl very stable. For the few things lacking there are
workarounds, and Mattia is always very obliging should you be faced
with serious trouble.

I've developed an app in Perl/Tk as well (www.uploadaway.com), and I
have to say that I find wxWindows far better in performance and looks.
The familiarity of the native GUIs helps users accept the app more
readily also.

>I'm particulary interested in the HTML support, because I >would like

I'm working on one too and using the STC control, i.e. scintilla as the
editor. You can download the current preview version for Windows here
and take a look:

http://www.wordit.com/prima
(Btw, the website was generated by the app)

It will be commercial too, but if you want to work together on the HTML
functions I'm open to that. I have a testing version, and we could
probably create a little open source editor as a by product?

[wxperl-users] Wx::ListCtrl, sorting

hello
i whish to sort my ListCtrlItems.
the ListCtrl is in report mode.

i noticed the SortItems function, but it only sorts the items after the

is there a function/a way to sort the items after the text?

if not, what would be a good/fast way do do this myself?
think that's a very mathematically problem.

but I got an "idea" yesterday.
i took a look at your samples and noticed in caret.pl the shortcut in the menu:
($file->Append($id_blinktime, "&Blink time...\tCtrl-B");)
i implemented it now this way in my application. not exactly what i need but
this will do it too.

but i'm curious:
this is nowhere documentated. where can i find informations about this feature?
what can i use everything there? "Ctrl-" and "Alt-" are clear, but what about
only the "Delete" keyboardbutton or only an "A" or "B" or "Shift-" ?

<snip>

<snip>

hello
my opinion is that wxPerl and wxWindows are at a usuable state of stability.
both have still some bugs and you have to do workarounds from time to time but
that's not that often.

here stuff that i found while programming an more or less complex application
(a MUA: http://coding.soapy.ch (download currently broken, will work again
tonight at about 20.00):

oh, before i begin: i use wxPerl 0.10 (wxWin 2.2.9) and
the things i described here are tested on win98 and redhat 7.2

i can't use the 0.11 built because of a bug (already reportet to mattia) wich i
can't do a workaround for in my application and i can't expect users of the
application to change the wxPerl lib themselve. and i don't know if the problems
described below are already fixed in 0.11 or if they are wxwindows bugs)

####################

Wx::ComboBox:

- GetCount broken on Linux, but works on Windows
- GetString "broken" on Win, but works on Linux
  not totally broken, the problem is that if you do GetString on a not existing
  index it should return nothing. on Win it returns first garbage and if you do
  it again it always returns "!"

so, this two things mean to me that if i wish to know all the content of a
ComboBox, i have to get it this way:

if($Wx::_platform == $Wx::_msw)
{
	for($i=0; $i<$this->{attachments}->GetCount; $i++)
	{
		print $this->{attachments}->GetString($i) . "\n";
	}
} elsif($Wx::_platform == $Wx::_gtk)
{
	while($string = $this->{attachments}->GetString($i++))
	{
		print $string . "\n";
	}
}

####################

Wx::Choice

"Number" and "GetString" broken on Windows, don't know about linux.
(the same problem with GetString like at ComboBox)

####################

Wx::ListBox

"Number" broken on Windows, don't know about linux

####################

Wx::MessageDialog

something wrong with linux. mattia already gave a workaround:
@Wx::GenericMessageDialog::ISA = 'Wx::MessageDialog';

####################

Wx::TreeCtrl in a Wx::Dialog:

problems with renaming on windows (there are much mails in the archive about
this). It's a wxWindows bug and not fixed till today.
someone programmed at the problem but it was never fixed properly
(my workaround: removed the feature of my application that needs this)

####################

Wx::ListCtrl

Windows:
If you insert a bold Item at the top the list, the headerlabel change to bold
too. wxWindows bug. works on linux.
"Fixed" in newer wxWindows version than  2.2.9. no more bold headerlabels
but instead of this problem there's a new: the bold item's arent handled
properly if you remove or insert another one above the bold one.
(a reason why i can only use wxPerl builts compiled against 2.2.9 and no newer)

####################

Wx::TreeCtrl

SetItemBold broken on Linux, not on Windows.
my workaround: change the background color instead of set it bold
-> generates another problem (this time with windows). the item's on whicht the
background color was changed once have an ugly yellow fontcolor if i select them
later

####################

think i found more but i reported them already to the list and forgot it now.

like i said, both (wxPerl and wxWindows) both still have bugs.
but for most of them there are workarounds.

so, if you wish to program your editor, you should expect to stumble over such
problems like i described because not every little thing in wxPerl/wxWindows is
tested on every platform (well, the users of the library are here for something
too, right?)

hope my little experience report/review helps you to decide if you'll use wxPerl
or not. I suggest you to do it, it's worth it after my opinion.
and i made the experience that mattia is always very nice and obliging if you
need a special built for some reasons.

[wxperl-users] A few things + questions ..

[Hermann-Marcus B. <he...@ci...>]

Hello,

i want to tell the developers of wxPerl, that this project is one of the
most interesting momentarily developed. It would be a shame, if wxPerl
wouldn't reach one day version 1.0 (as it looks momentary for promising
projects like Soap::Lite (still 0.55) or Inline (still 0.43)).

Since I would like to change completly from Tk to wxPerl, I would like to
know, how stable it is in the moment. I'm developing a rather large CMS for
an inhouse project (which will become probably never Open Source, but who
knows). I'm particulary interested in the HTML support, because I would like
to develop a simple HTML editor (i have done it already for Tk, but Tk
pushes here to its borders). I looked in the demo, but the dynamic HTML demo
is not working (Activestate Perl 5.6, Win 2000). So, how good will be the
HTML-Support inside of wxPerl? Would it be possible to develop an editor, in
whom a user can dynamically change the text or insert images (drag'n'drop)?

Thanks,
