TShellListView a little over-zealous with "List"
lazarus / 21-General

I am not sure if this is a Linux thing, but when I use a
TShellListView and set ViewStyle to vsList I get the same display as
the vsReport just sans the Headings.

How can I nobble that to just see the file name?

I did some searching and found a "Delete-Column" discussion and I
tried that. But it seems to delete all but the Size, or {gasp} Crash
Cinnamon.

To wit: Left is vsReport and Right is vsList

Does it work correctly in a TListView?

On Windows it is working correctly with Laz-trunk/FPC 3.2.2,
Laz2.2RC1/FPC3.2.2, Laz 1.8.4/FPC 3.0.4 (all 32 bit, trunk also 64
bit). It must be widget-set thing then... What widgetset are you using
in Cinnamon? And of course: Always mention your Lazarus and FPC
versions (along with bitness).

Thanks, is there some sample code I can try? When I dropped one on a
form and selected "vsReport" it does not show the headings as the
Shell version does.

I just looked at TListView and cannot find a way to link it to a
TTreeView and no idea on how to use that either.

Thanks, but no idea, but it is whatever comes with the stock Mint 20.1
Cinnamon.

Since Cinnamon (which is a Desktop Environment) is a fork of GNOME,
you're most probably using the GTK2 Lazarus Widgetset, which also
happens to be the default for Linux in Lazarus. Unless you have
changed it in the project options, o.c.

I checked the report on Ubuntu 21.04/gtk2 and can confirm the issue.
And it also happens with a simple TListView.

As a workaround you could use the vsSmallIcon or vsIcon viewstyles;
they only display the filenames, in a less compact layout, though.

Thanks, I had already tried them and they take up way too much room
per file.

I guess "the Tree+List components do not get much use as they are both
unfinished.

Weird stuff like one uses FolderSort and the other uses SortType. Some
uniformity would be good practice.
Path and PathName etc. Too many inconsistencies between them both.
Look to be developed by 2-different people who never talk to each
other.

Unfortunately changing that will not be backwards compatible
