Isn't this event suppose to trigger when adding, deleting images ?
Does not seem to do anything here.
laz 1.8.0 Windows.

The following code works fine with Lazarus Trunk/FPC 3.0.4:
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
Button1Click
(
Sender
:
TObject
)
;
var
Bmp
:
TBitmap
;
begin
Bmp
:
=
TBitmap
.
Create
;
try
Bmp
.
Width
:
=
16
;
Bmp
.
Height
:
=
16
;
Bmp
.
Canvas
.
Brush
.
Color
:
=
clRed
;
Bmp
.
Canvas
.
FillRect
(
0
,
0
,
16
,
16
)
;
ImageList1
.
Insert
(
0
,
Bmp
,
Bmp
)
;
finally
Bmp
.
Free
;
end
;
end
;
procedure
TForm1
.
Button2Click
(
Sender
:
TObject
)
;
begin
ImageList1
.
Delete
(
0
)
;
end
;
procedure
TForm1
.
ImageList1Change
(
Sender
:
TObject
)
;
begin
ShowMessage
(
'changing'
)
;
end
;
OnChange is triggered both on Button1 and Button2 click.

I must apologize, it seems I set the OnChange event to the wrong TimageList, not the one I was actually
working with..
Sorry about that, disaster is averted !
