Thread: [Fxruby-users] New tab item not visible via block

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I have an FXTabBook object to which I'm adding pairs of FXTabItem and
FXFrame.  This works perfectly until I try to add a pair from within a
menu item message block.  In other words, I want to be able to click
"New" in the file menu and have a new tab item with its contents
appear.  The trouble is that although the code is being executed, the
FXTabItem is not appearing.

Here is the code (simplest case):

<pre>
require 'fox'
require 'fox/colors'

include Fox

class PlayTextMainWindow < FXMainWindow
	def initialize(app)
		# Call the base class initialize() first
		super(app, "PlayText", nil, nil, DECOR_ALL, 0, 0, 800, 600)

		# Menu bar, along the top
		menubar = FXMenubar.new(self, LAYOUT_SIDE_TOP|LAYOUT_FILL_X)

		# Separator
		FXHorizontalSeparator.new(self,
			LAYOUT_SIDE_TOP|LAYOUT_FILL_X|SEPARATOR_GROOVE)

		$editorTabs = FXTabBook.new( self, nil, 0, 
			LAYOUT_FILL_X|LAYOUT_FILL_Y|LAYOUT_TOP)

		# NOTE: This call to addEditor WORKS
		addEditor( "New" )

		# File menu
		filemenu = FXMenuPane.new(self)
		FXMenuCommand.new(filemenu, "&New\tCtl-N\tNew Text
Window.").connect(SEL_COMMAND) do
			# NOTE: This call to addEditor is made, but a new tab DOES NOT appear!
			addEditor( "test", "", true )
		end
		FXMenuCommand.new(filemenu, "&Quit\tCtl-Q\tQuit the application.", nil,
		  getApp(), FXApp::ID_QUIT)
		FXMenuTitle.new(menubar, "&File", nil, filemenu)
	end

	def addEditor( title, filename="", focus=true )
		ti = FXTabItem.new( $editorTabs, title, nil,
			LAYOUT_FILL_X|LAYOUT_FILL_Y|LAYOUT_LEFT )

		p title
		# Play text window
		frame = FXHorizontalFrame.new( $editorTabs,
LAYOUT_FILL_X|LAYOUT_FILL_Y|FRAME_LINE )
		editor = FXText.new( frame, nil, 0,
			TEXT_WORDWRAP|LAYOUT_FILL_X|LAYOUT_FILL_Y)
		if( focus )
			$currentTextWindow = editor
			$currentTextWindow.setFocus()
		end
	end

	def create
		super
		show(PLACEMENT_SCREEN)
	end
end

if __FILE__ == $0
	application = FXApp.new("PlayText", "(C)2004 Duane Johnson")
	stw = PlayTextMainWindow.new( application )
	stw.enable

	# NOTE: This call to addEditor WORKS
	stw.addEditor( "duane", "", true )

	application.create
	application.run
end
</pre>

I'd love to have some ideas on where I can modify this.  Thanks!
