[wxperl-users] printing a PDF from wxPerl

[Mike S. <Mik...@Do...>]

Not sure if this is an obvious question I am just missing or not, but....

We generate server-side PDFs and then pass them to wxPerl clients.  By 
default we just open them with the appropriate mime-type application on 
the client platform (so evince/xpdf on gtk, Preview on OSX, Acrobat on 
Win32). 

The issue now is if we can print without having to open first.  For 
Linux and OSX, worst case we can just do a system call to "lp 
filename.pdf" and everything is fine, but not sure how to print a PDF in 
Win32 without first opening it in Acrobat. 

I noticed that Mark Wardell has wrapped wxPdfDocument, and that the 
wxPdfDocument folks plan on providing a wxPdfDC (similar to 
wxPostscriptDC) for printing in their next release -- is that the way to 
go??

Thanks in advance for any insight/suggestions.

Mike.

Re: [wxperl-users] Where did EVT_TREE_ITEM_GETTOOLTIP go?

[Mark D. <mar...@zn...>]

Hi,

I don't think it was ever wrapped.

The attached diff against Wx-0.72 wraps a couple of wxMSW specific events:

EVT_TREE_ITEM_GETTOOLTIP
EVT_TREE_STATE_IMAGE_CLICK

It also wraps EVT_MAXIMIZE

I put the TreeEvent macros in Constant.xs as that seemed the best place to check for wxMSW.

I put EVT_MAXIMIZE in Event.pm as I thought it ought to be with EVT_ICONIZE.

Regards

Mark

The API documentation (http://www.wxwindows.org/manuals/2.8.0/wx_wxtreectrl.html) mentions the use of EVT_TREE_ITEM_GETTOOLTIP and wxTreeEvent::SetToolTip to set the tooltip for individual tree items. However, when I tried to use EVT_TREE_ITEM_GETTOOLTIP it's nowhere to be found in wxperl - I've grepped the source tree of Wx-0.67 and it's just not there (but it is in the wxWidgets-2.8.0 source tree). So my question is simple - has it been replaced with another method of setting tree item tooltips, or was it just left out?

[wxperl-users] wxPerl::Styles

[Eric W. <scr...@gm...>]

Hi all,

Here's a style shortcut package to complement wxPerl::Constructors

  http://scratchcomputing.com/svn/wxPerl-Styles/trunk/

I realize that style('hscroll', te => 'process_enter|multiline') isn't 
much shorter than (style => Wx::wxHSCROLL()|Wx::wxTE_PROCESS_ENTER()|
Wx::wxTE_MULTILINE()), but shortness is only an interim goal.  By 
processing the constants as strings, I'm hoping to enable a better 
XRC-like thing.  In the meantime, it's shorter enough that I think I 
can get all of the style onto one line more often than not.

Thoughts?

This is copied from the documentation.  See the svn above.

  use Wx qw(
    ALIGN_RIGHT
  );
  ... wxALIGN_RIGHT ... ;

Becomes:

  use Wx ();
  use wxPerl::Styles 'wxVal';
  ... wxVal('align_right') ... ;

  use Wx ();
  use wxPerl::Constructors;
  use wxPerl::Styles 'style';
  ...

  my $text_ctrl = wxPerl::TextCtrl->new($self, 'some text here',
    style('hscroll', te => 'process_enter|multiline')
  );

Thanks,
Eric

[wxperl-users] Creating OpenGL Tesselation (Concave Polygon) on GL Canvas

[Vaughn S. <vau...@in...>]

All,

I am seeking a way to construct a concave polygon on a glCanvas window.  =
I understand that it is mandatory to describe concave polygons as a =
"tessellation" ... and I cannot locate any information in this regard.

At a macro level I'm thinking that I should be able to implement a =
subroutine as shown below; any information would be greatly appreciated.

Vaughn

########################################
sub drawConcaveOutline
########################################
{
   ## Create the tesselator object
   my $pTess =3D gluNewTess();

   ## Set callback functions
   gluTessCallback($pTess, GLU_BEGIN,  \&glBegin);
   gluTessCallback($pTess, GLU_VERTEX, \&glVertex2fv);
   gluTessCallback($pTess, GLU_END,    \&glEnd);

   ## Smooth minimizes seeing tessellation
   glShadeModel(GL_SMOOTH);=20
  =20
   ## Begin the polygon
   gluBeginPolygon($pTess);

   ## Begin the one and only contour
   gluBeginContour($pTess);

   ## Feed in the list of vertices
   ##
   ## << Not sure the syntax here >>
   =20
   ## Close contour and polygon
   gluEndContour($pTess);
   gluEndPolygon($pTess);

   ## All done with tesselator object
   gluDeleteTess($pTess);

Oops, that's right.  Those both require a title, so that doesn't make=20
much sense.  I suppose I should make wxPerl::Foo->new() be equivalent=20
to Wx::Foo->new() then?

Indeed!

Could you let me know what

It will save me compiling a 2.6.3 version to figure out why my version checking is wrong.

By the way, the test is at line 338 of ProcessStream.pm so you could comment out to continue until I sort out the version problem.

Re: [wxperl-users] wxPerl-Constructors

[Mark D. <mar...@zn...>]

Hi Eric.

I think this looks rather good.

I would not fret about the inheritance / isa issues. I don't think you can solve these in a none restrictive way without ending up with a syntax at least as verbose as the standard - or something completely different.

Provided it points out the issues in the pod (which it does) I would say that is good enough.

Regards

Mark

[wxperl-users] Possible to wrap wxChmFSHandler from src/html/chm.cpp

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

Hi,

I just want to ask if it is possible to wrap the wxChmFSHandler class 
from wxWidgets. The problem to me seem that there are no header files 
(just a cpp) file for this class. This also applies for the rest of the 
html classes which seems pretty closed to me (not accessible from 
outside nor "wrapable").

This will also mean to compile wxWidgets (wxPerl too ?) with 
wxUSE_LIBMSPACK. How is this done? I compiled libmspack under windows 
into a DLL, so this won't be the problem.

  I applied a slightly modified form of your patch, the only
substantial change is forcing integer arithmetic and using sprintf

Re: [wxperl-users] Wx::Perl::ProcessStream

[Mark D. <mar...@zn...>]

Johan,

Thank you very much for the feedback.

I shall update the documents so that it is clear your own code must add line endings. I might also have two methods:

Write
WriteLine

On the timer, there is a default 500 millisecond delay on polling. The code that reads input will keep reading line by line and raise an event for each line until the buffer is empty, and then timeout for 500ms.
It operates this way so that if you are running multiple processes you get a line from each in turn rather than any single process 'blocking' reads from everything else.

Writes are serialized with the reads so the net effect of a write / read response is 500 * 2 which is exactly the 1 second you have observed.

The 'timer' used for polling is the Wx::Timer which claims between 1 second and 1 millisecond accuracy depending on the OS and, no doubt, a multitude of other factors. The same polling timer is shared between all external processes that are running. The timer only runs when you actually have external processes running.

I shall add a

PollingInterval

method so that the timing can be set to whatever is suitable. I'll leave 500ms as the default.


Many thanks for the feedback - I'm pleased that it worked for you.

Best Regards

Mark

As far as I can test, it does exactly what it is supposed to do!

The only problem I had (and that took me hours of debugging) was why
the slave process wouldn't read the data that was written to it using
WriteProcess.

Well, the slave used <STDIN>, and it was just patiently waiting for
the newline before making any input available. I was slighty misled by
the documentation:

       $process->WriteProcess('a message to stdin');

Which I'd suggest to change to:

       $process->WriteProcess("a message to stdin\n");

as a reminder that newlines are important.

When playing Q & A with a slave program I noticed that the response is
not snappy. Apparently there's a 1-second poll interval hidden
somewhere. It would be nice it this could be reduced to 200ms or
something similar. (But it could be hidden deeply in Wx -- didn't
investigate).

For me, this module is exactly what I've needed for a long time!

Thanks,
        Johan

Re: [wxperl-users] ScrolledWindow drawing (was Re: wxPerl Standard Selection Dialogs )

[Mark D. <mar...@zn...>]

As a final piece in my ScrolledWindow saga, there's 
http://www.wxperl.co.uk/example6.pl.txt

This works as is with the posted diff.
To use without the posted diff, you must uncomment the EVT_PAINT call and comment out 'OnDraw'.

It also has a 'run refresh loop' option on the menu bar so you can watch it consume all your resources. :-) (it shouldn't).

It works as a way to observe the issue I've been trying to resolve and a crude test if you decide to apply the diff.

No more GDI from me this week.

Mark
