ToolBar, the Return

I have added a Toolbar to the Navigator,
I add a bunch of Buttons,
I learned how to move a button if I forgot one
set its oproperties (name, Icon),
Cmd-Mouse and move to the destination.
I still do not know the size of the icons (and so I used 64/128 pixels squared)
Once done,move Toolbar1 into its target Window.

Now, the next tricky part:
Where I must click to add code to a button ?

Pretty stupid, isn’t it ?

(next step will be to Hide/Show the Toolbar, probably for Sunday).

OK, I found.

Once Toolbar1 is in a Window, it is possible to add events (Right-Click).

Very intuitive, of course. I understand why I built my own years ago based on Canvas. And it works fine / Xplatform.
