[Fxruby-users] creating an error message without showing main window

[Joel V. <vj...@PA...>]

I just realized how easy this is to do, so here is for posterity (i.e., 
so I can google it when I forget how to do it :) The trick is to avoid 
app.run (which would never terminate by itself because win.show never 
happened, so there's nothing to close). Apologies if this is common 
knowledge...

require 'fox'
include Fox

app = FXApp.new
win = FXMainWindow.new(app, "")

app.create

FXMessageBox.error(win, MBOX_OK, "caption", "message")

Thanks for sharing this, Joel. It's also perhaps worth pointing out 
that this approach works for the more general case of just popping up 
any kind of dialog box. For example, to show a file dialog:

	require 'fox'
	include Fox

	FXApp.new do |anApp|
	  FXMainWindow.new(anApp, "") do |theMainWindow|
	    anApp.create
	    puts FXFileDialog.getOpenFilename(theMainWindow, "Pick a file, any 
file", Dir.getwd)
	  end
	end
