#6208 — pyGTK identify a button

Hi all,
i'm trying to write a simple windows with two button in GTK, i need a 
way to identify wich button is pressed.
Consider that:

the two button are connected (when clicked) to infoButton(self, widget, 
data=None)

infoButton() is something like this

infoButton(self, widget, data=None):
	# discover wich button was pressed
	...
	# say hello to the button
	if button1pressed:
		print "Hi, button1!"
	else:
		print "Hi, button2!"

so, how can I know wich button was pressed without using data and 
without reading the label of the button (i could have buttons with the 
same label)

If data is needed, can someone pls tell me how to set it properly in 
glade 3.8

thanks
Nico

From documentation:
handler_id = object.connect(name, func, func_data)

So:

button1.connect(when is pressed, your_function, 1)
button2.connect(when is pressed, your_function, 2)
(This code is conception, I don't really know how is done in GTK).

On the callback:
infoButton(self, widget, data=None):
        # discover wich button was pressed
        ...
        # say hello to the button
        if data == 1:
                print "Hi, button1!"
        else:
                print "Hi, button2!"

thanks but, as i've sayed before, i can't use func_data 'cause i don't 
know how to set it on glade3.8, that is the program i use to create the 
GUI.
Anyway, i think this is the only way to identify the button :-/

I'm not terribly familiar with GTK, but I believe the 'widget'
parameter is the button that was clicked on. Whatever means you have
for distinguishing them (saving another reference to each object in a
named variable, etc), you should be able to do with that parameter.

#!/usr/bin/env python

import gtk

def console_display( button , args ) :

    a0 , a1 , a2 = args

    print '    %s .... %s %s ' % ( a0 , a1 , a2 )


window = gtk.Window()

window.set_title( "gtk.buttons.01" )
  
window.set_size_request( 300 , -1 )

window.set_position( gtk.WIN_POS_CENTER )

window.connect( "destroy" , gtk.main_quit )


# Create VBox and add in Window

vbox = gtk.VBox()

window.add( vbox )


# Create buttons

dict_buttons = {
    12   :  [ 'OneTwo' , 'Buckle ' , 'My Shoe' ] ,
    34   :  [ 'TreFor' , 'Shut   ' , 'The Door' ] ,
    56   :  [ 'FivSix' , 'Pick   ' , 'Up Sticks' ] ,
    78   :  [ 'SvnAte' , 'Lay    ' , 'Them Straight' ] ,
    910  :  [ 'NinTen' , 'Big    ' , 'Fat Hen' ] }

list_keys = dict_buttons.keys()

list_keys.sort()

for this_button in list_keys :
    
    this_name = dict_buttons[ this_button ][ 0 ]
    
    b = gtk.Button( this_name )

    b.set_name( this_name )

    b.connect( "clicked" , console_display , dict_buttons[ this_button ] )

    vbox.pack_start( b )


window.show_all()

gtk.main()

This looks similar to a question I posted about 2 weeks ago

In gtk 2.1.6 (i think) & earlier you could use widget.get_name() to 
return the id of the widget.
this no-longer works since 2.1.7
the pygtk forum suggests this is because widget id's are not necessarily 
unique & caused problems elsewhere, to be honest most of the explanation 
went above my head.
I did find a work around & that was to use gtk.buildable.get_name(widget)
but is is probably cleaner to use a discrete callback for each button.
