Dear Kevin :
Thanks your help and it's working good for my purpose.
I find some issue about the column click event disappear in this case .
And the column resize event and scrolling event seems not support to let
me capture it.
Since you tell me to edit the subitem on the ListView has not standard
Windows function. I try the other way to implement this case. Maybe the
Grid View more fit my target .
thanks so much .
Here is your sample I put a little event processing to avoid that
ListView resize event and scrolling event has been triggered .
#!perl
use strict;
use warnings;
use Win32::GUI qw();
use Win32::GUI::Constants qw(/^WS_/ /^VK_/);
my $MW = Win32::GUI::Window->new(
-name => 'MW',
-size => [350,550],
-pos => [250,125],
-text => "Listview Example",
-pushstyle => WS_MINIMIZEBOX |
WS_SYSMENU,
);
my $LV_0 = $MW->AddListView(
-name => "LV_0",
-size => [300,500],
-pos => [6,6],
-fullrowselect => 1,
-hottrack => 0,
-gridlines => 1,
-checkboxes => 0,
-singlesel => 1,
-oneclickactivate => 1,
-editlabel => 1,
-visible => 1,
-nocolumnheader => 0,
);
my $timer = $MW -> AddTimer( "Update", 300 );
my($Item,$SubItem);
my $Edit = Win32::GUI::Textfield->new(
-parent => $LV_0,
-name => 'Edit',
-visible => 0,
-popexstyle => WS_EX_CLIENTEDGE,
-onLostFocus => sub {
#Label isn't
changed if user clicks off textfield
my $self =
shift;
$self->Hide();
$timer ->
Interval(300);
return 1;
},
-onKeyDown => sub {
my($self,$flags,$vkey) = @_;
#Label is
changed on RETURN key
if($vkey ==
VK_RETURN){
my $item =
$LV_0->Item($Item);
if($SubItem){
my $sub
= $item->SubItem($SubItem);
$sub->Text($self->Text());
}else{
$item->Text($self->Text());
}
$self->Hide();
}
#Label isn't
changed on ESCAPE key
elsif($vkey ==
VK_ESCAPE){
$self->Hide();
}
$timer ->
Interval(0);
return 1;
},
);
$LV_0->InsertColumn(
-index => 1,
-width => 150,
-text => "Column_0",
);
$LV_0->InsertColumn(
-index => 2,
-width => 1000,
-text => "Column_1",
);
for(0..100){
$LV_0->InsertItem ( -text => [ ( sprintf "index %03d", $_ ), ( sprintf
"subindex %03d", $_ ) ] );
}
$MW -> Show();
Win32::GUI::Dialog();
exit(0);
sub MW_Terminate{
-1;
}
sub LV_0_MouseDblClick {
my($x,$y,$flags) = @_;
my($item, $subitem, $flag) = $LV_0->SubItemHitTest($x,$y);
return 1 unless defined $item;
my @rect;
if($subitem){
@rect = $LV_0->GetSubItemRect($item,$subitem);
}
else {
@rect = $LV_0->GetItemRect($item);
}
$Edit->Show();
$Edit->Left($rect[0]);
$Edit->Top($rect[1]);
$Edit->Width($rect[2]-$rect[0]);
$Edit->Height($rect[3]-$rect[1]);
$Edit->Text($LV_0->GetItemText($item,$subitem));
$Edit->SelectAll();
$Edit->SetFocus();
$Item = $item;
$SubItem = $subitem;
return 1;
}
sub Update_Timer{
$LV_0 -> Redraw(1);
}
sub LV_0_MouseMove{
$Edit -> Hide();
$timer -> Interval(300);
}

RE: [perl-win32-gui-users] How to edit ListView subitem ?
Miller,
After digging through the Windows SDK documentation, I'm fairly certain
that Windows doesn't allow subitem labels to be edited. You can get around
this, though, by handling the label change yourself.
Here is a sample I put together from your code that allows subitems to be
edited. It does this by responding to the MouseDblClick event (instead of
the DblClick event), which displays a text box that the user can type in.
There is probably a better way to do this, but this works OK.
#!perl
use strict;
use warnings;
use Win32::GUI qw();
use Win32::GUI::Constants qw(/^WS_/ /^VK_/);
my $MW = Win32::GUI::Window->new(
-name => 'MW',
-size => [350,550],
-pos => [250,125],
-text => "Listview Example",
-pushstyle => WS_MINIMIZEBOX | WS_SYSMENU,
);
my $LV_0 = $MW->AddListView(
-name => "LV_0",
-size => [300,500],
-pos => [6,6],
-fullrowselect => 1, # Select every colnum's row at the same time
-hottrack => 0, # Auto select item , don't click item
-gridlines => 1, # Draw the border for list table
-checkboxes => 0, # Show the check box on the every row start
-singlesel => 1,
-oneclickactivate => 1, # Change the cursor to onecclick type while on
the select item
-editlabel => 1, # Can be edit
-visible => 1,
-nocolumnheader => 0, # Hide the column header
);
my($Item,$SubItem);
my $Edit = Win32::GUI::Textfield->new(
-parent => $LV_0,
-name => 'Edit',
-visible => 0,
-popexstyle => WS_EX_CLIENTEDGE,
-onLostFocus => sub {
#Label isn't changed if user clicks off textfield
my $self = shift;
$self->Hide();
return 1;
},
-onKeyDown => sub {
my($self,$flags,$vkey) = @_;
#Label is changed on RETURN key
if($vkey == VK_RETURN){
my $item = $LV_0->Item($Item);
if($SubItem){
my $sub = $item->SubItem($SubItem);
$sub->Text($self->Text());
}
else {
$item->Text($self->Text());
}
$self->Hide();
}
#Label isn't changed on ESCAPE key
elsif($vkey == VK_ESCAPE){
$self->Hide();
}
return 1;
},
);
$LV_0->InsertColumn(
-index => 1,
-width => 150,
-text => "Column_0",
);
$LV_0->InsertColumn(
-index => 2,
-width => 150,
-text => "Column_1",
);
for(0..100){
$LV_0->InsertItem ( -text => [ ( sprintf "index %03d", $_ ), ( sprintf
"subindex %03d", $_ ) ] );
}
$MW -> Show();
Win32::GUI::Dialog();
exit(0);
sub MW_Terminate{
-1;
}
sub LV_0_MouseDblClick {
my($x,$y,$flags) = @_;
my($item, $subitem, $flag) = $LV_0->SubItemHitTest($x,$y);
return 1 unless defined $item;
my @rect;
if($subitem){
@rect = $LV_0->GetSubItemRect($item,$subitem);
}
else {
@rect = $LV_0->GetItemRect($item);
}
$Edit->Show();
$Edit->Left($rect[0]);
$Edit->Top($rect[1]);
$Edit->Width($rect[2]-$rect[0]);
$Edit->Height($rect[3]-$rect[1]);
$Edit->Text($LV_0->GetItemText($item,$subitem));
$Edit->SelectAll();
$Edit->SetFocus();
$Item = $item;
$SubItem = $subitem;
return 1;

Hope this helps,

Subject: [perl-win32-gui-users] How to edit ListView subitem ?
Dear All :
Does any one know how to let the ListView subitem can be edit ?
Below is my sample code :
#!perl
use Win32::GUI ;
$MW = Win32::GUI::Window -> new( -name => 'MW',
-size => [350,550],
-pos => [250,125],
-text => "Listview Example",
-font => $font_T_8 ,
-style =>
WS_MINIMIZEBOX | WS_SYSMENU,
);
$LV_0 = $MW -> AddListView( -name => "LV_0",
-size
=> [300,500],
-pos =>
[6,6],
-fullrowselect => 1, # Select every colnum's row at the same time
-hottrack
=> 0, # Auto select item , don't click item
-gridlines => 1, # Draw the
border for list table
-checkboxes => 0, # Show the
check box on the every row start
-singlesel => 1,
-oneclickactivate => 1, # Change the
cursor to onecclick type while on the select item
-editlabel => 1, # Can be edit
-visible => 1,
-nocolumnheader => 0, # Hide the column header
);
$LV_0 -> InsertColumn( -index => 1,
-width => 150,
-text => "Column_0",
);
$LV_0 -> InsertColumn( -index => 2,
-width => 150,
-text => "Column_1",
);
#$LV_1 = Win32::GUI::ListView::SubItem -> new(
# -parent => $LV_0,
# -index => 1,
# -subindex => 1,
# );
for(0..100){
print $LV_0 -> InsertItem ( -text => [ ( sprintf "index %03d", $_ ),
( sprintf "subindex% 03d", $_ ) ] ), "\n";
}
$MW -> Show();
Win32::GUI::Dialog();
exit(0);
sub MW_Terminate{
-1;
}
sub LV_0_DblClick{
print "SelectedItem:", $LV_0 -> SelectedItems(), "\n" ;
$LV_0 -> EditLabel( $LV_0 -> SelectedItems() );
}
sub LV_0_BeginLabelEdit{
print "BLabelEdit:", "@_", "\n";
}
sub LV_0_EndLabelEdit{
print "ELabelEdit:", "@_", "\n";
}
---End--
