Re: [pygtk] How to get widget size?

Profit not to understand the operation of the progress bar.
Somebody to indicate to me as it would be the code to
implement the following thing: Simply I want that when
pressing "button2" the progress bar is increased in a 10% for example.
--- BEGIN-CODE
def create_progress_bar():
win = GtkDialog()
win.set_position (WIN_POS_CENTER)
win.set_policy(FALSE, FALSE, TRUE)
win.set_title("Progress Bar")
vbox = GtkVBox(spacing=5)
vbox.set_border_width(10)
win.vbox.pack_start(vbox)
label = GtkLabel("Undating ...")
label.set_alignment(0, 0.5)
vbox.pack_start(label, expand=FALSE)
pbar = GtkProgressBar()
pbar.set_usize(225, 20)
vbox.pack_start(pbar)
You need a "static" variable holding the update value so that
the bar keeps exapanding. Ugly hack:
update_val = 0.10
pbar.set_data ("update_val", update_val)
def updateBar(_button2, pbar=pbar):
update_val = pbar.get_data ("update_val")
pbar.update(update_val)
update_val = update_val + 0.10
pbar.set_data ("update_val", update_val)
def updateBar(_button2, pbar=pbar): # bad code
pbar.update(0.15) # bad code
button = GtkButton("close")
button2 = GtkButton("Update")
button.connect("clicked", win.destroy)
button2.connect("clicked", updateBar)
win.action_area.pack_start(button)
win.action_area.pack_start(button2)
button.set_flags(CAN_DEFAULT)
button.grab_default()
win.show_all()
END-CODE

Everything works correctly. But the load of the image is very slow,

It does not load the PNG image, why?.
In other programs I have seen that they load PNG images without
problems.
Note: I don't know much about the gtk rc stuff.
I think what you've seen the other programs use is a gtk-theme-engine,
not the "regular" rc parsing.
I've never gotten that crap to work, you have to do some garbage like
this (example doesn't work):

I have received silence by answer. It is that I have asked a

Hello everybody. As I told in my last email, I spennt another night on this

should let me drag a node over another, and then the dragged node becomes a
child of the other one. drag_data_set were methods of my node object, which
led to many segfaults. Now, I placed them away but I still have problems.
I pass a string to look up at which node is passed, as you can only pass
strings in a drag data I think. My problem is, the dragged data disappears,
the other ones remain as they were and a gtk warning appears. What do I

Does anybody have a patch to allow a GtkCList's "append" method

The 0.6.6 *_wrap_gtk_clist_append requires a sequence object.
Not passing an argument would be a good trigger for this.
Also, I can't find any /good/ tutorial information on GC's
and styles. gtk.org information is fragmentary at best.
I can't get a bg_pixmap to appear behind the cells of my clist.
