Hi folks,
I just started working through examples in the Shoes manual, and am trying:
Shoes.app do
stack :width => 200, :height => 200 do
background red
hover { clear { background blue } }
leave { clear { background red } }
end
end
As I understand it, the (initially red) stack should turn its background
blue on mouse entry, then turn red again when the cursor leaves. When I
test it, however, the entire app window turns blue on entry, and I can't
get it to turn red again. Am I doing something wrong, not getting how
it's supposed to work, or is this a bug?
I'm running Shoes 0.r1091 on a PowerPC (OS X 10.5.5).
I know that Seth already answered, but I have a somewhat different
approach than his, and I wanted to share.
The way I'd go after it is to stack two backgrounds on top of each
other, and the show/hide the top one when the hover happens:
Shoes.app do
stack :width => 200, :height => 200 do
red_bg = background red
blue_bg = background blue
blue_bg.hide
hover { blue_bg.show }
leave { blue_bg.hide }
end
end
One thing I noticed when playing with this: it looks like the leave
event doesn't fire when you move your mouse into the stack and then out
of the window. Interestingly enough, it does fire if you bring your
mouse back into the window but outside of the stack. It's hard to
explain, but it becomes obvious with a couple of added puts:
Shoes.app do
stack :width => 200, :height => 200 do
red_bg = background red
blue_bg = background blue
blue_bg.hide
hover { puts "hover"; blue_bg.show }
leave { puts "leave"; blue_bg.hide }
end
end
This behavior is not what I would expect. Is it a bug, or is there
something I'm missing?
