I manage manually the visibility of my columns for my TsListView.

I hide the columns by giving them a width of 0.

Because my columns are resizable I need to prevent the user of resizing the “hidden” columns.

I intercept the resizing messages.

Code:

procedure TMediaLibrary.ListViewNewWndProc(var Msg: TMessage);
var
hdn: ^THDNotify;
begin
if Msg.Msg = WM_NOTIFY then
begin
hdn := Pointer(Msg.lParam);
if ((hdn.hdr.code = HDN_BeginTrackW) and (LvPlaylist.Column[hdn.Item].Width = 0)) or
((hdn.hdr.code = HDN_BeginTrackA) and (LvPlaylist.Column[hdn.Item].Width = 0)) then
begin
Msg.Result := 1;
end else
begin
FListViewOldWndProc(Msg);
end;
end
else
FListViewOldWndProc(Msg);
end;

Now what I want to do is remove the change of the cursor when the mouse hovers a “hidden” column.

Because currently it changes to a crHSplit cursor even if the column has a width of 0.

Thanks!

Hello! Perhaps this component is suitable for your task – TacListView 🙂

It has TacColumn.Visible property.

Wow, Thank you!

It looks like it is what I need 😀

It seems that this component does not allow the resizing of the columns…

I need this feature too… 🙂

Thanks!

User can change column size by mouse and you can change it by TacColumn.Width property.

Sorry, I meant reordering of the columns… 😀

Did I missed something?

[KSS]

No, you had not missed anything 🙂 Columns reordering is not supported now, but this feature will appear in one of next component release 😉

Ho! One last question…

Is it possible to get the row information when clicking on it?

Example: Retrieve the information of the 3rf column of the 2nd row clicked.

You can get Element object “TacListView.GetElementAt(MousePos: TPoint)”. See a new version of component with columns reorder on forum.

OMG Thank you soooo much!

Now everything I need is included in your component.

Later!
