Using a terminal I start my app. After opening and closing a form (not

[TGtkWidgetSet.Destroy] WARNING: There are 4 unreleased GDIObjects, a

This is an internal message for the gtkwidgetset only. When using the
LCL, this messasage should never occur.
This appear, when for instance you forgot to free four TBitmap, so it is
not an internal message only.
I guess somehow I'm not closing the form correctly. Can anyone provide
a clue or a direction for me to check what is still open. Or maybe a
link that describes what steps to take to discover the unreleased
objects.
What is on your forms ? How are you closing your forms ?
Use heaptrc (compiler options -> linking).
If this does not show the unreleased memory, then compile the LCL clean
with -dDebugLCLComponents.

You are correct. It is coming from my imagelist. Now I include
ImageList1.Destroy; in my formclose procedure.
How did you create this Imagelist ?
If you put it on a form in the IDE or if you created it with a form as
owner, it should get destroyed when you close your form.

I created the imagelist using the IDE (imagelist editor). But in doing so the
IDE reported an error when saving from the imagelist editor. I don't recall
what the error said but it offered to continue or cancel. I decided to
continue. I then saved the project and closed. When I re-opened the project
and my imagelist along with my graphics was there. That's all I did.
But I have also discovered that a Tbitbtn with a graphic is leaving a
unreleased GDIObject when closing. So the issue is not limited to the
imagelist. My graphics are in a sub-directory just below the project. Was
this wrong? Is there a different way I should have added graphics?
I don't know how you close your forms, but normally the graphics are
automatically freed in this case.
I've tried it here, but I cannot reproduce.
