Hey all,
Ariel Serbin and I have notice something strange occurring with the
splitter demo, and specifically the splitter control itself.
Run the script attached, a previous post contained it. Then, drag the
splitter to the left a short distance, then back to the right and equal
amount. You'll notice that there is a nasty artifact showing up on the
screen. Of course when your test in the text field overlaps this
artifact, it is resolved within the relative area of the text [Rob and
all may know the proper names, but unfortunately I'm not that in depth].
I believe it has something to with the underlying DC objects that are
drawing the splitter control, but am fully aware that I don't have the
understanding to fix this.
WinXP SP2, AS 5.8.7, Win32-GUI 1.02 and Win32-GUI 1.02_03 this occurs.

Note: For ease of replicable visibility, we've widened the splitter
control in the code below.
--CODE-
#!perl -w
use strict;
use warnings;
use Win32::GUI;
my $mw = Win32::GUI::Window->new(
-title => "Splitter Test",
-pos => [100,100],
-size => [500,400],
-onResize => \&main_resize,
);
$mw->AddTextfield(
-name => "TF1",
-multiline => 1,
-width => 200,
);
$mw->AddSplitter(
-name => "SP",
-left => 200,
-width => 10, #FATTY
-onRelease => \&do_splitter,
);
$mw->AddTextfield(
-name => "TF2",
-multiline => 1,
-left => 200 + $mw->SP->Width(),
);
$mw->Show();
Win32::GUI::Dialog();
exit(0);
# NEM splitter event gets 2 parameters. The first (as always)
# is the window object the wvwnt came from - in this case the
# splitter window; The second depends on the splitter orientation:
# if horzontal it is the top coordinate; if vertical it is
# the left coordinate. (coordinates relative to the parent's
# client area)
# The splitter window is moved by the splitter object, so you only
# have to re-position your other windows
sub do_splitter {
my ($splitter, $coord) = @_;
$mw->TF1->Width($coord);
$mw->TF2->Move($coord+$mw->SP->Width(), 0);
$mw->TF2->Resize($mw->ScaleWidth()-$mw->SP->Width(),
$mw->ScaleHeight());
}
sub main_resize
{
my $self = shift;
$mw->TF1->Height($self->ScaleHeight());
$mw->SP->Height($self->ScaleHeight());
$mw->TF2->Resize($mw->ScaleWidth()-$self->TF1->Width()-$mw->SP->Width(),
$mw->ScaleHeight());
}
