Open a system browser (from background menu). This is the best tool from
which to snoop around.
In top-left pane, type "cmd-f" (or "alt-f") for "find class" (or choose it
from the menu icon in the scroll bar of that pane).
Type "button" into the pop-up, press return.
A list of buttonish classes pops up, amongst which figures
"SimpleButtonMorph". Looks promising! Select it.
Look at class side (for instantiation): #newWithLabel: -- this might just
be exactly what we wanted.
Open a workspace (b/g menu) to try it out. In the workspace, type
(SimpleButtonMorph newWithLabel: 'Hello, world') openInWorld
select it and choose "do it" (or "cmd-d"). Well, that's definititely a
button, but it doesn't do much.
Look in browser on instance side. Hmm... #target:, #actionSelector:,
#arguments: -- those look quite promising.
Back to the workspace:
(SimpleButtonMorph newWithLabel: 'Hello, world')
Much more interesting!
Have fun making buttons.
