[pygtk] Style problem

2001-06-12 Thread Eduardo Ferro


Hi

I am trying to change the font of a label with the following code:


fuente = gtk.load_font("-*-helvetica-*-*-*-*-24-*-*-*-*-*-*-*")
strMensaje = string.replace(strMensaje,'\\n','\n')
gtkLabel = gtk.GtkLabel(strMensaje)

estilo = gtkLabel.get_style()
estilo.font = fuente
gtkLabel.set_style(estilo)

And it works, but no as I expected... the font change for this
widgets, but it also changes for all the other ones in the
aplication...

Is there any other system to change the font of a widget?
how can I change the style of a "concret" widget?

thanks in advance

Forget this message...
I don`t know that the .children return a list so i have a list with a
gtkLabel, but not the gtkLabel
So the code must be like:

def ioCambiada(gtkButton):
gtkLabel = gtkButton.children()[0]
gtkLabel.set_text('Prueba')


Sorry :(

[pygtk] Button child

2001-05-16 Thread Eduardo Ferro

I need to get the label of a button in its signal handler...
now the code that i use is:

def ioCambiada(gtkButton):
gtkLabel = gtkButton.children()
print gtkLabel
gtkLabel.set_text('Prueba')


And the output is:

[eferro@drako iopipe]$ ./virtualio.py 
[]
Traceback (innermost last):
  File "/usr/lib/python1.5/site-packages/libglade.py", line 28, in __call__
ret = apply(self.func, a)
  File "./virtualio.py", line 25, in ioCambiada
gtkLabel.set_text('Prueba')
AttributeError: set_text

So it seems that the gtkLabel have a correct GtkLabel object instance
but it dont let me use the GtkLabel methods... i try with get()
set_text() but neither of them work

Any info about it

Yes, I explain bad that i want. I only want to avoid to explicity put
a hand made dic to autoconect.
I expect that i can get the handler names that contains the glade file
to generate automaticaly the dictionary and to auto connect... of
course I will generate this callbacks

I will study the code that you send. it seems very interesting


Thanks for the info/code

[pygtk] problem with add_timer & file reading

2001-03-20 Thread Eduardo Ferro

Hi!

I use this code to try to log  the contents of a file at a scrolled
window. It read all the file and include the contents in the window,
and later program a callback with the timeout_add function.
When the callback is called, it read the file (because it could grow
up) and add the new readed text to the window and to a list.

The problem is that when i add some text to the open file, when the
callback read the contents it dont`read the first one or two
characters added... and it add a newline character to the string
readed (i supose that it is the normal behaviour but i need to add
only the real contents)

Any suggestions would be apreciated
Thanks in adavance

[pygtk] focus dude

2001-03-20 Thread Eduardo Ferro

Hi!

I need to create a program to generate a few buttons and the user must
select one of then using the mouse or the keyboard.
I want that the user use the cursor arrow keys to select the button
and then press enter to run the asociated command. I want to show some
kind of feedback to the user, for example i think that when it select
some button with the keyboard the button background can be resalted
like when the mouse pointer pass over the button

How can i disable the color change of the button when the mouse
pointer pass over the button?
How can i change the keyboard focus to another widget and simulate
that the mouse pointer has enter to this widget??

Thanks in advance

   fcntl.ioctl(self.cd.fileno(),CDROMREADTOCHDR,chdr)
   print struct.unpack('BB',chdr)

it allways print (0,0) but this ioctl change the structure...

For example:

gtkWindow = GtkWindow()
gnoIcono = GnomePixmap('caution.png')
gtkWindow.add(gnoIcono)

Thanks for the info!
I now should kill externaly (from the main thread) the new thread
generated by the start_new_thread function, now in the new thread i
get the tid with get_ident and save it at global variable (bad
practice i know, but it`s only for testing  :-))

But i didn`t found a method to kill the thread like i usualy do in C
Somobody know how to do this???

But without the events it isn' t very usefull paint nothing at the
root window. Any case i think that it should be possible because some
C programs like root-tail do it, they repaint its output when some
window erase it

Anyway thanks a lot
