It's just one more datapoint, but I got this error when using the 
SingleInstanceChecker.  Curiously if I delete the single instance 
checker well before I shut down the app then all is fine, but if I kill 
it during shutdown then I get this error.

Could this be what you are seeing?

  Yes, you need to install wxWidgets too. It is usually safer to
either use the RPMS or build wxPerl directly on the machine.

[wxperl-users] changes in doc/view framework of wxPerl 0.26 ?

[Gerrit W. <gw...@gr...>]

Hi ,

upgrading my windows installation to the newest active-state perl and
wxperl 0.26 breaks one of my apps using the doc/view framework.
When loading a document or creating a new one, my document constructor
GenericDocument::new() gets called.
But from GenericDocument::OnCreate() i can't get any debug message, so i
think it won't never be calledand the doc object remains uninitialized.

The same application behaved well under windows before the upgrade, as
it did on my linux server running open-suse 10.0 with wxperl 0.25.

Have there been any changes to the doc/view framework that i missed, or
have i done it the wrong way and it only happend to work by fortune?

please can anyone give me a hint?

regards,

Gerrit Wichert

p.s. this are the code snippets concerning doc/view:

app::OnInit:

[wxperl-users] Problems using Wx::Package::Win32 and PerlApp

[Mark W. <ma...@ne...>]

Hi All/Mark,
 
I am still having problems using PerlApp since using wxPerl 0.4902 (now
0.4904), when I exit I get an application error.
If I build without the --gui option, I see an error when I exit:
 
"rmtree failed: Directory not empty"
 
And I am most definitely NOT using the --clean option.
 
If I use Wx::Package::Win32 (0.07) by using the BEGIN { use
Wx::Package::Win32 } command I get the following error on startup but the
original error I got when exiting the program disappears.
 
Failed to load shared library '' (error 126: the specified module could not
be found.)
(this message is repeated six times)
 
I am using WinXP SP2, AS Perl 815 (also tried 817), wxWidgets 2.6.3 and
wxPerl 0.4904 (tried all from 0.4902)
 
Thanks for any help.

[wxperl-users] Trouble with Wx::WebKit

[Dan S. <da...@si...>]

Okay, so I've been trying to get a perl interface to the wxWebKit 
class, and have been *mostly* successful. If you've got OS X 10.3 or 
better, http://www.sidhe.org/~dan/Wx-WebKit-0.02.tar.gz (it's hit 
CPAN, but not the mirrors yet) gets you access to a webkit control, 
which is good. Even works (mostly) which is better. (version 0.01 
sorta works, except I didn't set @ISA right so you couldn't invoke 
methods in any parent class. D'oh!)

It's that mostly part that has me puzzled, and I'm not sure if 
there's a bug in my WxPerl code, my XS interface to the wxWebKit 
class, or in the underlying wxWebKit class itself.

I've attached a test program (OS X only) that demonstrates the 
problem. It's a hacked up wxGlade program, and has a main window 
split in two, with the HTML rendering widget in the *right* side of 
the window. If you run this with the USE_WEBKIT environment variable 
unset, it used wxHtmlWindow, if you have the USE_WEBKIT env variable 
set (any value) it uses wxWebKitCtrl.

The problem is that with the wxWebKitCtrl, the HTML widget is on the 
*left* side of the window, not the right. (It's on the right, where 
it should be, with the wxHtmlWindow widget) This is... surprising. 
The size of the webkit control is correct -- it doesn't take up the 
whole window, it's just like the upper-left corner coordinates are 
incorrect.

I'm assuming the perl code's correct, since the only code difference 
between the two html rendering widgets is which is created. It's 
certainly possible I've bobbled the XS code somewhere, but there's 
really not all that much to it so if there's a mistake I'm not seeing 
it. (Not that it wouldn't be a blatantly obvious mistake, of course 
-- these things usually are :) I'm kinda hoping the problem's not in 
the underlying Wx 2.6.2 code, since that'll be something of a pain to 
fix.

So, could someone take this and try and duplicate the problem, to see 
if I screwed something up?

[wxperl-users] Dependency issues

[Marcus <li...@wo...>]

I copied my Perl directories from one Linux installation to another. 
When I run my script I get this dependency issue:

Can' load .../auto/Wx/Wx.so for module Wx:libwx_gtk2_adv-2.6.so.0 no 
such file...then a reference to XSLoader.pm

I've forgotten how things work under Linux. Do I need to install 
wxWidgets? Why would I otherwise need the library "libwx_gtk2_adv-2.6.so.0"?

This reminds me, do we have a list of wxPerl apps. Shouldn't we have one for both open and closed source. Then developers can study source examples, and see how cool commercial apps can be written in wxPerl.

Suresh, wxPerl can be very structured and fairly similar to the C++ counterpart, except for specific syntax. Look at the wxPerl demo and examples.

Of course, being Perl you can stick to a neat structure, or make it look quite chaotic...but that's the freedom of Perl we appreciate :-)

Initial Comment:
The latest implementation of Wx::LogTraceMask filters
@_ through sprintf. This is nice if one wants to make a
nice formatted log message, but it also makes a
diagnostic if one messes up and feeds Wx::LogTraceMask
only one parameter. To help the user find such goofs (I
tend to make them when I convert a LogDebug or a
LogError to LogTraceMask), I've added a carp:

[wxperl-users] wxPerl.app and PREFIX

[John R. <jr...@ce...>]

It's taken me a day to get the latest wxPerl CVS update running. The  
problem is that I set PREFIX when I run Makefile.PL, because I don't  
want a CVS build overwriting the distribution (yes, wxPerl is  
included in OSX 4) or release installations of wxPerl.

The problem is that MakeMaker creates a file, wxPerl.c, by using the $ 
(INSTALLSITEARCH) Makefile variable (which is Mattia's doing, in  
build/Wx/build/MakeMaker/MacOSX_GCC.pm), and that when the PREFIX is  
set on the Makefile.PL command-line, MakeMaker builds it with  
quoting. That means that a filename string in wxPerl.c is written as  
"$(SITEPREFIX)/darwin-thread-multi-2level/auto/Wx/wxPerl.app/Contents/ 
MacOS/wxPerl". That string gets passed to execv, which tries to stat  
the file and fails, because the filesystem doesn't know about $ 
(SITEPREFIX).

The easy solution is to also specify INSTALLSITEARCH on the command  
line. Since some installation things pay attention to INSTALLSITEARCH  
and others pay attention to PREFIX, it seems that the two should  
point to the same directory -- but I didn't test to see if that's the  
case.

Mattia, it would be nice to add a note about this to INSTALL.pod.

  I suppose you already tried to call SetSelection in the event handler?

  Even if it worked now, it is not guaranteed to work in the future.
In general, synthesizing events and making controls process them is
a bad idea.

  I added it to wxPerl CVS, FWIW.

  Generic is a widget implemented entirely using wxWidgets code (for
example wxCalendarCtrl). Univ
stands for wxUniversal and is a wxWidgets port (like wxMSW, wxGTK, wxMac,=

...) except it only relies on basic primitives (device context, window)
and implements all the controls in a generic way. It is used in wxMGL.

You need to ask this on wx-users (feel free to CC me). I will wrap
any missing part of the API.

  You can't "simply" invoke some $textctrl->Print( ... ). You need to
create a printing DC (as is done in the example) and draw the text on it.=

  Ok with me. Data seems a bit generic, but I don't have any

A few minor changes needed to get wxPerl running with
the latest (1May2006) CVS HEAD. MacSetMetalAppearance
was recently made private. wxHOURGLASS_CURSOR is
defined to a function which returns a const wxCursor*,
and for that matter the wxBusyCursor ctor takes a const
wxCursor. wx/mediactrl.h has a preprocessor guard
statement checking for the existance of
wxUSE_MEDIACTRL; if it's not defined including the
header is a no-op.

Subject: [wxperl-users] Request for Wx::Data Namespace


A little history first...

Our company (DonorWare) has been creating a WxPerl front-end to our
business logic for the past year and a half.  Now we are wanting to
refactor our code and provide the application framework back to the
Perl community.  Also, a while back I sent an email to this list for
WxPerl contractors and got some immediate responses -- thank you!  One
of those contractors (Brad Embree) has been working on Dynamic Panels
and Dynamic controls to allow an application to build itself dynamically
off of metadata received from data calls.  The other contractor (Eriam
Schaffter) is about to start on the refactoring project for making Wx
frames and controls "data-aware" using POE as the backend event loop.
By the way -- this all works in Win32, Linux and OS X.   Again, my
thanks to Mattia for his help getting the POE::Loop::Wx module working
last year.

All that to say....

We would like to use the Wx::Data namespace for this "data-aware"
POE framework for WxPerl.  Here are some examples of what will be done:

Wx::Data::Manager -- spawns a POE session to manage data
publish/subscribe events between data sources and Wx frames/controls
that consume those data sources.

Wx::Data::Client::HTTP -- spawns a POE session to asynchronously manage
requests to HTTP-based data sources.  This is our first one, but we
could see the addition of Wx::Data::Manager::SOAP,
Wx::Data::Manager::DBI, etc.  In this HTTP version we use
Data::Serializer to manage serialization, encryption, compression, etc.

Wx::Data::Server::HTTP -- used on the server side to create a daemon to
respond to requests from Wx::Data::Client::HTTP.  This allows you to use
your existing business logic modules (or write new ones) that can be
used by the controls in your WxPerl app.

Wx::Data::Control -- a namespace for creating data-aware controls that
can automatically subscribe their data needs to the Wx::Data::Manager,
and automatically receive the responses to populate the control.  For
example, Wx::Data::Control::CodeChoice would make adding a Wx::Choice
control that populates itself off of a code table back on your server
very simple and trivial.

We also have a framework using PAR that requires a minimal binary
launcher for the operating system you are running on that then fetches
Pure Perl WxPerl code that can be run cross-platform.  This allows you
to make central updates to your application and your users get a fresh
version of your application code each time they login.  We could also
look at refactoring this and adding to CPAN if anyone is interested.

That gives you an idea of how we would like to use the Wx::Data
namespace.  This is all working already in our existing
namespace/application, but we wanted to make sure this direction would
be acceptable before refactoring into a CPAN module/bundle.

Mattia -- is Wx::Data acceptable to you?

Thanks in advance to any feedback or suggestions.

Mike.

business logic for the past year and a half.  Now we are wanting to
refactor our code and provide the application framework back to the
Perl community.  Also, a while back I sent an email to this list for
WxPerl contractors and got some immediate responses -- thank you!  One
of those contractors (Brad Embree) has been working on Dynamic Panels
and Dynamic controls to allow an application to build itself dynamically
off of metadata received from data calls.  The other contractor (Eriam
Schaffter) is about to start on the refactoring project for making Wx
frames and controls "data-aware" using POE as the backend event loop.
By the way -- this all works in Win32, Linux and OS X.   Again, my
thanks to Mattia for his help getting the POE::Loop::Wx module working
last year.

All that to say....

We would like to use the Wx::Data namespace for this "data-aware"
POE framework for WxPerl.  Here are some examples of what will be done:

Wx::Data::Manager -- spawns a POE session to manage data
publish/subscribe events between data sources and Wx frames/controls
that consume those data sources.

Wx::Data::Client::HTTP -- spawns a POE session to asynchronously manage
requests to HTTP-based data sources.  This is our first one, but we
could see the addition of Wx::Data::Manager::SOAP,
Wx::Data::Manager::DBI, etc.  In this HTTP version we use
Data::Serializer to manage serialization, encryption, compression, etc.

Wx::Data::Server::HTTP -- used on the server side to create a daemon to
respond to requests from Wx::Data::Client::HTTP.  This allows you to use
your existing business logic modules (or write new ones) that can be
used by the controls in your WxPerl app.

Wx::Data::Control -- a namespace for creating data-aware controls that
can automatically subscribe their data needs to the Wx::Data::Manager,
and automatically receive the responses to populate the control.  For
example, Wx::Data::Control::CodeChoice would make adding a Wx::Choice
control that populates itself off of a code table back on your server
very simple and trivial.

We also have a framework using PAR that requires a minimal binary
launcher for the operating system you are running on that then fetches
Pure Perl WxPerl code that can be run cross-platform.  This allows you
to make central updates to your application and your users get a fresh
version of your application code each time they login.  We could also
look at refactoring this and adding to CPAN if anyone is interested.

That gives you an idea of how we would like to use the Wx::Data
namespace.  This is all working already in our existing
namespace/application, but we wanted to make sure this direction would
be acceptable before refactoring into a CPAN module/bundle.

Mattia -- is Wx::Data acceptable to you?

Thanks in advance to any feedback or suggestions.

Mike.

Philosophy first: I don't think having the wxPerl wrappers act  
differently from the underlying wxWidgets is a good idea: It will  
serve mostly to drive people nuts.

Next, terminology: wxControls *are* wxWindows. What you mean to say  
is that wxHTMLWindow  is derived from wxPanel, and wxMozilla and  
wxWebKit aren't.   In fact, wxWebKit is derived from wxControl, but  
wxMozillaBrowser is derived from wxWindow directly and  
wxMozillaWindow is derived from wxFrame.

Kevin Ollivier, one of the developers of both wxMozilla and wxWebKit,  
is quite active on wx-...@li.... I suggest you ask  
there what is the best strategy for replacing a wxHTMLWindow with  
each of the other html widgets. Make clear at the outset what derived  
functions from wxPanel or wxScrolledWindow are lacking in wxMozilla  
and wxWebkit, and which can't be achieved by either plopping one into  
a wxScrolledWindow or deriving a class which simply inherits from  
both. Once that's worked out, you can decide whether it makes more  
sense to execute the strategy in C++ and add wxPerl bindings to it or  
to do it directly in wxPerl.

  FWIW the wxWidgets people's plan is to implement[1] wxHtml-2 which
can have the current rendering engine or Mozilla or IE (using the
ActiveX) or WebKit or whatever as backend. So they like option 2 as
well. Not that this will help you ;-)

[wxperl-users] Extra wrappy bits for Wx::Mozilla and Wx::WebKit

[Dan S. <da...@si...>]

Okay, so I've been doing some fiddling with my app to test some of 
the fancier HTML rendering capabilities of the non-WxHTMLWindow HTML 
widgets (mozilla and webkit) and I hit what I'd consider a pretty big 
annoyance -- these things aren't drop-in replacements for 
WxHTMLWindow.

That is, the basic HTML option in Wx is a window, while WxMozilla and 
WxWebKit are both controls. Can't swap in one for another. (And yeah, 
I know, the method names are different, but that's easy enough to 
deal with)

Anyway, since I wrote both the Wx::Mozilla and Wx::WebKit wrappers, I 
can make things a little different. The question here is, what'd be 
best? Would it be better to:

1) Have Wx::Mozilla and Wx::WebKit widgets be windows or panels, and 
basically be compatible with WxHTMLWindow in usage? (Which'd make the 
perl versions different than the underlying C++ widgets)

2) Add in a compatibility class in the distributions that provides a 
window or panel version of the widgets in addition to the control 
version they are by default

3) Leave it as is and fix it in my app shims since nobody much cares anyway. :)

I'll admit to being tempted towards option #2, with some 
WxHTML-compatible methods thrown in as an extra (WebKit has 
SetPageSource rather than SetPage to send HTML to the widget, for 
example) but I'm not sure if that's really the best way to go about 
it.

Suggestions'd be greatly appreciated, thanks. :)

[wxperl-users] Printing STC documents

[Manuel R. <m....@te...>]

Hi,
did someone already get printing via STC working?

Is it possible and is the printing part supported by wxPerl's STC
wrapper?

Based on http://scintilla.sourceforge.net/ScintillaDoc.html#Printing can
someone give me a short example of how it should work and used in
wxPerl?

Generally I think I've not yet understand the principles of printing (DC
=3D Device Context okay but what does this mean exactly?).
In the examples printing is implemented with a canvas. But what do I do
if I simply want to print the contents of a Wx::TextCtrl?=20

Thanks for giving me some hints...

[wxperl-users] Selecting a Notebook Tab with right mouse button

[<AOu...@fr...>]

Hi,

I was wondering, if it's possible to select a Tab in a Notebook using 
the right mouse button and if, then how ?

Problem is, that I'm using the right mouse button to show a Popupmenu 
for the Page, if I click on a Tab. But if I click on a Tab, that isnt 
the the current Page, I want to change the Page, to this one first.

Until now I have to select the Page first (using left mouse button) and 
then click it (with right button) to open the Popupmenu.

So far I tried to use this in the Event Handler for the right button:

my $hEvent = Wx::MouseEvent->new(wxEVT_LEFT_DOWN);
$hEvent->SetId($this->GetId());
$this->ProcessEvent($hEvent);

, but without any luck.

And since HitTest isnt implemented under wxPerl (and not on all 
wxWidgets Ports), I cant determine on which tab the right click was.

Does anyone has any idea how to solve this problem ?

Btw: What is the difference between wxWidgets "univ" and "generic" ?

Many thanks in advance,

Andre

It build and installed fine.
