[Fxruby-users] fxruby message tester

[meinrad r. <mei...@gm...>]

moin!

many people including myself have asked on this list for a method to 
find out what messages a widget handles. i have written a simple script 
that does the job.

the script is not perfect and i can not guarantee that the result is 
exact, but it seems fairly ok to me. a handful of messages cause 
segfaults or typeerrors (maybe because the handler expects specific 
message data instead of nil) so they were excluded.

as soon as i have time to continue work on my gui builder, i will test 
all fox widgets and make the results publicly available. until then the 
attached script should help you to test any fox widget.

have fun!

here comes the script:

#fxruby message tester by henon

require "fox"
include Fox

$stdout.sync=true


$messages=Fox.constants.grep( /SEL_/).sort-[	
	"SEL_ENTER", # segfault
	"SEL_LAST", # segfault
	"SEL_LEAVE", # segfault
	"SEL_NONE", # segfault
	"SEL_PAINT", # segfault
	"SEL_SIGNAL", # type error - expects integer
	"SEL_VERIFY", # type error - expects string
]

def test_widget( w)
	raise TypeError unless w.kind_of? FXWindow # or even FXObject ?
	
	# provide a receive callback for each message
	$messages.each{|c|
		const = Object.const_get(c)
		w.connect(const) { puts "received message: #{c}" }
	}
	
	# send all messages
	puts "Testing #{w.class}:"
	$messages.each{|c|
		#~ puts "sending: #{c}"
		w.handle(w, MKUINT(0, Object.const_get(c)), nil)
	}
	puts "finished!!"
	
	# remove the callbacks
	$messages.each{|c|
		const = Object.const_get(c)
		next if c=="SEL_UPDATE"
		w.connect(const) { 0 }
	}
	
end

application = FXApp.new("Hello", "FoxTest")
main = FXMainWindow.new(application, "Hello", nil, nil, DECOR_ALL)
w=FXButton.new(main, "the widget to be tested")
application.create()

test_widget(w)

#main.show(PLACEMENT_SCREEN)
#application.run()
