The pastie you linked to seems to reveal bugs in Shoes itself.
The hover(), click(), and leave() methods do not work correctly in a
Button's block. When a button is clicked on, hover() seems to be
called. The hover(), click(), and leave() methods also do not work in
Widgets at all.
This works, however:
class Thing < Widget
def initialize &blk
self.width=300
self.height=300
background blue
yield if block_given?
end
end
Shoes.app do
thing do
button 'Test' do
alert "Boo"
end
end
end
When typing out this out, though, I found a third bug—butting braces
around the button's block instead of do...end raises a syntax error!
Anyways, the code above should work. Keep in mind that Widgets seem to
still be spotty, and Shoes is still in its birth pangs, but Mr. Why
still is doing an incredible job for one man.
Sincerely,
Joshua Choi
