Peter, I don't think I can help you with any of your problems I'm sorry to =
say.=20
I'm especially sorry not to be able to help you with initially setting =
checkboxes within a ListView. Don't know how to do that. Was not =
something my app needed to do, but I can see how it would be useful. I =
can share a couple things I do know howver that might be of interest to =
you or someone else:
Peter, you already know that you can get the value of the checkbox state =
for a row in the ListView using
EXAMPLE
$row=3D15;
$checked=3D$LV->ItemCheck($row); # checkbox state is 0 or 1.
This is documented.
But, what is not documented is how to get the value of other properties =
within the ListView such as -text and -image
EXAMPLE
$row=3D15;
%data =3D $LV->ItemInfo($row,0);
$image=3D $data{-image}; # image nbr in image list displayed =
at row 15=20
$column1text=3D $data{-text}; # text value in first column of row =
15 =20
%data =3D $LV->ItemInfo($row,1);
$column2text=3D $data{-text}; # text value in 2nd column of row 15
You can change the value of a property associated with a row of the =
ListView by
EXAMPLE
$LV->ChangeItem(-item =3D> $row, -image =3D> 1); # display 2nd image =
in image list
Here is a complete declaration of the ListView and its ImageList:
EXAMPLE
$B1 =3D new Win32::GUI::Bitmap("deselected.bmp"); # off light
$B2 =3D new Win32::GUI::Bitmap("selected.bmp"); # on light
$IL =3D new Win32::GUI::ImageList(16, 16, 0, 2, 10);
$IL->Add($B1, 0); # image 0 or first image in list
$IL->Add($B2, 0); # image 1 or 2nd image in list
$LV =3D $W->AddListView(
-name =3D> "ListView",
-left =3D> 12,
-top =3D> 70,
-height =3D> 260,
-width =3D> 670,=20
);
$LV->View(1); # detailed listing, i.e. columns and rows
$LV->SetImageList($IL,1);
# enable gridline and checkboxes cabability=20
# fullrowselect defined below, but not activated with SendMessage
$LVM_SETEXTENDEDLISTVIEWSTYLE =3D 0x1000 + 54;
$LVS_EX_GRIDLINES =3D 0x001;
$LVS_EX_FULLROWSELECT =3D 0x020;
$LVS_EX_CHECKBOXES =3D 0x004;
$LV->SendMessage($LVM_SETEXTENDEDLISTVIEWSTYLE, 0,
$LVS_EX_GRIDLINES | $LVS_EX_CHECKBOXES,
);
HOW DO YOU KNOW WHAT ROW IN THE LISTVIEW HAS BEEN SELECTED BY THE USER???
EXAMPLE =20
########################
sub ListView_ItemClick {
########################
$row =3D shift; =20
}
Off the subject a little, here is a little trick that is useful to someone =
wanting to initially set focus on a text box and have the data highlighted =
in replace/overwrite mode.=20
EXAMPLE
$DetailSearchTXT->SetFocus();
$DetailSearchTXT->Select(0,length($DetailSearchTXT->Text()));
