Lazarus 4 TStringGrid Columns not appearing
lazarus / 10-Designer

I've tested this out in both Windows 11 and Linux Debian using gtk2
components.  I am running Lazarus 4 (as installed by fpcupdeluxe) with
FPC 3.2.2

If I have an existing grid on my form with columns defined, then I
select the grid and click the Columns property to bring up the list of
columns and then I add columns, they are not appearing in the Object
Inspector.  I have to reload Lazarus to see them.

Recently I tried repeating with a new grid and the columns did not
appear either.

I was wondering if this is an issue with my setup or a bug in Lazarus
4.

I do not see the same behavior in Lazarus 3.8 (also installed using
fpcupdeluxe - installed after I noticed the issue in 4).

Seems to be a bug.

Here is my Win-10 observation. Possible different from yours

- New App / Drop TStringGrid on the form
- Open "Edit Stringgrid"  by context menu of the Stringrid itself in
the OI (or presumingly the designer too)
- Add Columns in the editor
- Press OK
- OI does not show the columns in the component tree (The Columns Node
has no children).
- In the designer the columns are visible.

If however I right click the "Columns" node in the OI, and select "Add
Item" then the new column is shown (and all the missing ones are shown
too)

Also if in the OI, in the list of properties I go to Columns, and
click the "..." ellipses button to get the small window for just the
columns => then adding new columns will have them shown in the OI
tree.

Please report

I added info to the bug tracker (in the specified and related issues).
So, the problem is not in the trunk, and it looks like I did it ))
