Hi,
I could put together this example [code below], but I am stuck again on little things that are not so easy to find googling the docs.
1] How can I make the buttons fill all the third row length ?
2] How do I embed newlines in textT1 string, I see '\n' is not working.
3] How could i make the image in row4 fill its whole row (maybe same as [1])
4] How can I show the Squeak logo into image "i1" ? Just to have something nicer to display into examples.
---------------------
m := RectangleMorph new.
m openInWindow.

b1 borderWidth: 3 ; label: 'Button1'.

b2 borderWidth: 3 ; label: 'Button2'.
row2 addMorph: b1.
row2 addMorph: b2.
