[Steve T. <STU...@MU...>]

Here is a sample of a scroll area that adds and deletes controls. Hope this
helps.

require "fox"
require "myfoxcal"

include Fox

class FxTestWindow < FXMainWindow
	TIMER_INTERVAL = 20
	def initialize(app)
		# Invoke base class initialize first
		super(app, "FxTest", nil, nil, DECOR_ALL, 0, 0, 600, 600)

		i = 1
		@buttons = []
		outsideFrame = FXVerticalFrame.new(self, LAYOUT_FILL_X|LAYOUT_FILL_Y)
			horzFrame = FXHorizontalFrame.new(outsideFrame,
LAYOUT_FILL_X|LAYOUT_FILL_Y)
				FXButton.new(horzFrame, "Add Control").connect(SEL_COMMAND) do
					$stdout.print "button pressed\n"
					$stdout.flush

					v = FXButton.new(@contentFrame, "Button #{i}")
					v.create
					@contentFrame.recalc
					@buttons.push(v)

					$stdout.print "v = #{v}\n"
					$stdout.flush
					i += 1
					@timer = getApp().addTimeout(TIMER_INTERVAL, method(:onTimeout))
				end
				FXButton.new(horzFrame, "Remove Control").connect(SEL_COMMAND) do

					@buttons = @buttons[1..@buttons.size-1]
					@contentFrame.removeChild(button)

LAYOUT_FILL_X|LAYOUT_FILL_Y)
		@contentFrame = FXVerticalFrame.new(@scrollFrame,
LAYOUT_FILL_X|LAYOUT_FILL_Y)
			FXText.new(@contentFrame, nil, 0, LAYOUT_FIX_WIDTH|LAYOUT_FIX_HEIGHT, 0,
0, 200, 100)
			dtzone=MyDateTime.new(@contentFrame, 100,100);

	end

	def onTimeout(*args)
		@scrollFrame.setPosition(0,-(@scrollFrame.contentHeight))
	end

	# Start
	def create
		super
		show(PLACEMENT_SCREEN)
	end
end

def runGUI

	# Make an application
	$application = FXApp.new("Dialog", "FxWorld")

	# Open the display
	$application.init(ARGV)

	# Construct the application's main window
	FxTestWindow.new($application)

	# Create the application
	$application.create

	# Run the application
	$application.run
end

puts "before runGUI"
