[wxperl-users] 0.10 rpm

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

I forgot to mention, that the 0.10 rpm creates the subdirectory
"site_perl". My perl at least is looking for "site-perl". I had to copy
the files over so that perl could find wx.pm.

[wxperl-users] Linux: dialogs.pl error wx::FontData

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

I just installed v. 0.10 on Linux/perl 5.6.0.
Running the dialogs.pl sample I get the following error (and a crash)
after selecting the font dialog:
cannot locate ...method "New" via wx::FontData at line 220

Any ideas what is wrong?
Is FontData simply not implemented yet?

Thanks,

Marcus

[wxperl-users] New binary package for Win32

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

http://prdownloads.sourceforge.net/wxperl/Wx-0.10-wxmsw2.2.9-win32-1.zip

It is 0.10; the only change is that I recompiled wxWindows
with support for the comctl32.dll shipped with IE 3.0; this should
enable some features of wxListCtrl ( and probably wxTreeCtrl )
that were disabled.

[wxperl-users] Wx, perl, exe's, and Tk/Wx together

[<jm...@be...>]

Thanks to the developers of Wx and WxPerl. I have been trying to use Tk with Tk::HTML for displaying some complex web pages. Didnt work well at all. Found WxPerl, and using the demo, I was able to load the web page beautifully!!! Thanks again.
I often install my apps on machines without libraries such as Wx, Tk, or even perl. So I use perlapp or perl2exe. I have seen the previous post, so it looks promising to use Wx in these compiled apps.

One of my platforms is Solaris 2.5.1. Has anybody tried the compilers to produce apps on anything besides windows? They have worked well with Perl and Tk.

Has anyone used both the Wx and Tk Mainloops together? How about embedding a Wx window in a Tk window, with something similar to (-use).

Thanks again!

Sorry, I don't have the sources anymore ( it was 4 years ago... ),
and don't remember the details,
but for this kind of question you will surely get better answers
somewhere on comp.lang.perl.* ( or maybe in the FAQs )

BTW if you are using telnet you should probably use Net::Telnet,
    but that is not what is causing you problems

Why not use select() ( the 3-argument version ) or non-blocking sockets?
I used the 2nd solution a lot of time ago ( in a pure perl program )
and it worked fine.

[wxperl-users] splitting windows

[David R. <DR...@kn...>]

i have a splitter contained within a splitter, much like the wxPerl demo =
where the window is split vertically and the right pane split =
horizontally. i am trying to build mine from an external XML =
representation:

	<splitter type=3D"vert" size=3D"150" style=3D"0">
		<pane name=3D"LeftPane">
			<page name=3D"LeftPage" />
		</pane>
		<pane name=3D"RightPane">
			<splitter type=3D"horz" size=3D"150" style=3D"0">
				<pane name=3D"TopPane">
					<page name=3D"TopPage" />
				</pane>
				<pane name=3D"BottomPane">
					<page name=3D"BottomPage" />
				</pane>
			</splitter>
		</pane>
	</splitter>

The problem is to do with calling either SplitHorizontally() or =
SplitVertically(). Because the data structure is nested, i split the =
right pane horizontally before i split the main window vertically. It =
appears that splitting vertically is causing the horizontal split size =
to be lost. The same can be demonstrated in the wxPerl demo but changing =
the order of the split calls (lines 226/227). Obviously, in the demo, =
you can choose the order, but in a nested data structure as above, the =
approach is one of completely rendering the child splitter before going =
back to the parent.

Any ideas appreciated.

No, but since the release will be probably in 3/5 days, there is little 
point in compiling it now. If you still want to do that, you should
download the current CVS snapshot from the wxPerl site, which is what will 
be released, and contains the fix you want.

Re: [wxperl-users] Freezing windows

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

Thanks, it worked fine!
Sometimes the process pieces between appends/yields are a bit long but it=
 is
responsive enough.
I finally used Wx:SafeYield to disable the rest of the controls (they are
mainly settings), hope this has no side-effect.
The Yield call seems to have no noticeable effect on process speed too.

As a workaround you should change in cpp/helpers.h, around line 300

class WXPLDLL wxPliClassInfo:public wxClassInfo
{
public:
    wxPliClassInfo( wxChar *cName, wxChar *baseName1, wxChar *baseName2, 
                    int sz, wxPliGetCallbackObjectFn fn )
        :wxClassInfo( cName, baseName1, baseName2, sz, 0)
        {
            m_func = fn;
            //FIXME//
            m_baseInfo1 = wxClassInfo::FindClass( baseName1 );
// >>>>>>>> HERE, comment out with // the following two lines <<<<<<<
//if( m_baseInfo1 == 0 )
//croak( "ClassInfo initialization failed '%s'", baseName1 );
        }
public:
    wxPliGetCallbackObjectFn m_func;
};

BTW this is a workaround and it is being fixed in wxMac; please note
that if you want to run wxPerl on Mac you should debug problems
yourself ( you can always ask here, but since I don't have a Mac,
nor I ever used one, I can't be of much help )

You do know it has to be Wx case-sensitive?

Yes, I have. You do need to package the wx_version.dll with it. I can't
figure out your problem right now, but it did work with wxPerl
wx22_8.dll and ActivePerl build 623 (5.6.1), and wx MSW 2.2.x.

Perl2Exe is picky about module paths, so that could be a possibility.
Have you added Perl2Exe to your path variable, instead of running it
with a full path. Just a thought.

The problem is that you are stuck in an event handler, so the event
loop isn't processing new events. The 'real' solution for this
is using Wx::Process, that will be in the next release ( to be
released Really Soon ); as a workaround you could
put a Wx::Yield call right after the ->AppendText call
this way the GUI will be responsve only during the

[wxperl-users] Using wxPerl with Perl2Exe

[James L. <jl...@bi...>]

Hi everyone,

I want to use Perl2Exe to package up my application, but am having problems.

Perl2Exe runs fine, and produces a .exe file, but when I run it, I get the
following errors:

Compilation failed in require at C:\MY DOCUMENTS\PROG\TFC\PERL_SRC\TFFC.EXE
line 10.
BEGIN failed--compilation aborted at C:\MY
DOCUMENTS\PROG\TFC\PERL_SRC\TFFC.EXE line 10.

Line 10 is my 'use Wx' line.

Has anyone else succeeded in using Perl2Exe with wxPerl?

Thanks,

James

[wxperl-users] Freezing windows

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

Hi all..
First, thanks for the great wxPerl tool! I=B4m a newbie both to Perl and
wxWindows so i am having some hard times to get things working but
slowly my script gets looking user friendly.

I'm writing a GUI wrapper on Windows 2000 with Activestate to a
'untouchable' perl script, and for that i am using the open function to
get the output of the other script into a log window in the GUI. That
part look like this:

open STATUS, "theotherscript.bat -s$settings{SERVER} -check 2>&1 |"
                or die "can't fork: $!";
  while (<STATUS>) {
    $this->{TEXTWINDOW}->AppendText($_);
  }
close STATUS or $this->{TEXTWINDOW}->AppendText("-- ABNORMAL TASK
PROCESS ENDING. See log window for details. \n");

Now, if i stay at the window with the TextCtrl it works fine, i see the
output popping up while processing. But this can take a few minutes so
it will happen a lot that the user goes to another program, lets say to
check his mail. If he clicks the wxPerl tab again to see how it is going
nothing happens, the GUI will only come back when the child process
ends. Why?, can i change this behaviour?

Thanks again. Regards, Alejandro.

P.D. A fast link to download the samples at the home page would be a
great time saver! (i noticed that they exist only after reading some
really old messages on this list and then dowloaded them from ... i dont
remember).

well, think my question wasn't precise enough...
in fact i wanted the tab to work in a frame...

just saw it in the docs:
wxTAB_TRAVERSAL (Use this to enable tab traversal for non-dialog windows.)

think that's the most easy way to do it...

yes, there is a bug in ( the wxPerl wrapper of ) both functions :-(
( propagated by cut'n'paste... ); the
fixed version will be in the next wxPerl release; there is no
workaroud I know ( unless you want to recompile wxPerl ).

[wxperl-users] GetTextExtent

[David R. <DR...@kn...>]

I am having no joy with either wxDC::GetTextExtent() or =
wxWindow::GetTextExtent(). I've paid attention to the note saying "In =
wxPerl this method is implemented as GetTextExtent( string, font =3D =
undef ) returning a four element array ( $width, $height, $descent, =
$externalLeading )" yet I am getting an undef return value.

<example>

my $dc =3D new Wx::WindowDC($w);
$dc->SetFont($font);
my ($width,$height,$d,$e) =3D $dc->GetTextExtent($text);
print "text=3D$text width=3D$width, height=3D$height\n";

</example>

I've tried the above using $w->GetTextExtent($text) after a =
$w->SetFont($font) - same result. $w, $font and $text have all been =
verified to be expected values and don't seem to be part of the problem.

anyone have any experience or ideas?

thanks in advance,
