To Mr. Andrews,
Well, when you're initializing the Thing object, you're passing in a
block...but the Thing's initializer is not calling the block anywhere.
The code below might have some errors, but I'm whipping it up to demonstrate.
class Thing < Widget
def initialize &block
width = 300
height = 300
background blue
yield
end
end
Shoes.app do
thing do
button 'Test'
para 'Testing'
end
end
I tried running this, and it looks like it works. Mr. Why fixed a lot
of Widget bugs in the last build, though, so make sure you have the
latest version, Revision 970.
Also note that the changing the background by a button inside the
block only changes the button's background. I do not know if this is a
bug—perhaps you can ask Mr. Why. :)
Shoes.app do
thing do
button 'Test' do
background red
end
para 'Testing'
end
end
Sincerely,
Joshua Choi
