[wxperl-users] Questions and bug report

[Peter G. <pe...@pg...>]

I am using Fedora 5 with wxWdigets 2.6.3 and Wx-0.57

I have enclosed a program with an xrc file. Points 3 and 4 are the
most important.

1. Why do I need "use Wx::XRC" if I have "use Wx qw(:everything)"

2. There is a often a double free in libc when debugging. It doesn't
   always happen.
   $ENV{MALLOC_CHECK_} = 0 stops the complaint.  

3. In the program supplied:

   a) Using Menu/Load, it takes 5 seconds to load 5000 lines into a
      text control.
      Is there anything that I can do to speed this up? Is there a
      control that can do this faster? I often need to load files
      having tens of thousands of lines. 

   b) Using Menu/Test List Ctrl:

   The line 
     $list->SetColumnWidth(1,-1) ; 
   causes the error below. The documentation says that the -1 will
   force the header column to be the size of the data

   Is there a workaround or a fix?

  The usual recommendation is using wxListBox/wxListCtrl instead.
Since you say in another mail that this does not fullfill other requirements,
you might try ->LoadFile( $filename ) if it is inside a physical file.

  If I read the code correctly, the listctrl only has one column,
so the call should read

  $list->SetColumnWidth(0,-1) ;
