Is it possible to use Lazarus stock icon in common actions?

I am writing a text editor (BTW: SynEdit does already a lot of
things...). I would like to put a toolbar with common items in it
(open, save...), which will be duplicated also in the main menu. The
situation seems to call for an ActionList, so I tried to start with
it. But... do I have to search and load every single icon of every
TAction I want to include? It would be a pity: Lazarus provides a few
standard action, but without no icon already set?

That said, I have little clue. I tried some years ago, in Delphi, to
write a program using an ActionList, but without success. Now I am
trying again with Lazarus, but I can't find much documentation, so may
be I am starting with the wrong foot.

For very common actions like "Save" or "Undo", really I have to load a
TImageList with icons I should search who knows where?

TY in advance for any suggestion...

Yes, you need to build an image list containing your icons and
associate with the TActionList.

The actions in the list can in turn be associated with the TMenuItem's
of a main or popup menu, the ToolButtons of the TToolBar etc.

What I usually do is copy all the icons to a folder "MyProject/res/"
and (re-)build the image list from there. It's a liittle time
consuming at first if you need many icons but it's done just once.

Or you can have pre-built lists ready to be pasted in a forms
.lfm/.pas or in a common data module, say a "fileIcons" or "editIcons"
or whatever.

It's easier if you use icons collections (famfamfam, silkicons or
whatever); then all you need do is unzip the collection, delete the
uneeded icons and build the list.
