FXRuby: FXShutter and FXShutterItem trouble with setting bg color

I have been fruitlessly trying to get the bg color in the FXShutter and
FXShutterItems to black. I looked at the Fox API and I called every
single color method with FXColor::Black, but all to no avail. One would
assume that “@shutter.backColor = FXColor::Black” or
"@shutter.setBackColor(FXColor::Black)" would work, but they don’t, nor
do they work for the FXShutterItems. No matter what I do I get dark
gray as the bg color. Any help would be greatly appreciated.

Part of the confusion is that the shutter’s a nested widget. That is,
the “shutter” is the entire thing (i.e. the container) and so changing
its background color isn’t usually going to have much visible effect.

At the next level down are a number of shutter items, each of which has
a short, wide button that the user clicks to “raise” or “lower” that
shutter item, and a content area that contains the rest of the stuff for
that shutter item (usually, but not always, a collection of buttons).
You can access the button and content area for a shutter item using the
FXShutterItem#button and FXShutterItem#content instance methods,
respectively.

So to change what I think you’re calling the “shutter” background color,
you actually want to change the background color for the content area in
the shutter item of interest, e.g.

 shutterItem.content.backColor = FXColor::Black

If you want to change the background color for the “short, wide” button
for a particular shutter item, use:

 shutterItem.button.backColor = FXColor::Black

If you want to get at one of the widgets inside the content area, you
can of course do that too; e.g., save a reference to that widget when
you add it to the shutter item:

 # Create the shutter
 shutter = FXShutter.new(...)

 # Create a shutter item inside that shutter
 shutterItem = FXShutterItem.new(shutter, "Short & Wide, that's me")

 # Create some regular buttons inside this shutter item's
 # content area
 btn1 = FXButton.new(shutterItem.content, ...)
 btn2 = FXButton.new(shutterItem.content, ...)

 # Change button 1's background color to black
 btn1.backColor = FXColor::Black

I’m not sure if this covers what you were asking; if it didn’t, please
follow up.

Hope this helps,
