Re: [pygtk] get_active() of CheckButton added to ScrolledWindow
Hi,
Firstly, on a conceptual note, "self.window" is not really an accurate
name for the glade.XML object created. It does not represent any one
window, but rather the whole GUI (windows and widgets) created in Glade.
You can see the glade.XML object as a factory object, taking the XML
output from the Glade UI designer ("check.glade" in your case) as input
and giving you the constructed widgets as output.
Having said that, there is no way for the glade.XML object to know about
widgets that were created at run-time and not specified in its input XML
and that is why self.window.get_widget("test") returns None. Also the
string you passed as argument to gtk.CheckButton() is the button's label
and not it's name. The difference is that the label is the string that
is displayed on the button and the name is used as an internal string
identifier for the widget.
The most common way to achieve what you are trying to do here, is to
keep a reference to all new, custom-created widgets. So if you replace
"button = gtk.CheckButton('test')" with "self.button =
gtk.CheckButton('test')", you can simply do "state =
self.button.get_active()" in your "button2_clicked()" event handler.

[pygtk] get_active() of CheckButton added to ScrolledWindow
Howdy all,
I'm just learning pygtk and glade, and I have a question about
accessing widgets that were added during an called function. In my
example, I have two buttons. The first button that adds a checkbox to
a scrolled window area. The second button prints the activity status
(True/False) of the checkbox.
The first button works fine. However, when I push button two, python
says "AttributeError: 'NoneType' object has no attribute
'get_active'". Obviously, this means that I'm not reaching the
checkbox widget correctly.
So my question, how can I get properties of a widget added after the
initial glade file was loaded?
Here's my program, and I've attached my glade file. Thanks all!

"on_window1_destroy" : (gtk.main_quit) }
self.window.signal_autoconnect(dic)
return
def button1_clicked(self,widget):
button = gtk.CheckButton("test")
self.window.get_widget("scrolledwindow1").add_with_viewport(button)
button.show()

status = self.window.get_widget("test").get_active()

Re: [pygtk] Tooltips on comboBox

in my attempt to get tooltips I see that as I click on the arrow and the
popup appears, the tooltip disappears.
It seems the popup is a different gtk.Widget, and I should connect to that
one to attach tooltips. Is that correct? and in case how can I have that
widget?
I tried to connect to 'add' signal but it's never triggered. I see the
ComboBox has a child: a CellView, but if I understand correctly CellView
only displayes *one* line and moreover I was not able to add a tooltip
anyhow.
Can somebody clearify widh is the way a ComboBox pops a menu and how Ican
get to it's components to set a ooltip?
thanks

[pygtk] Adding Validation in TreeView: how to use 'edited' cb and stop any other processing?
Hi, I'm trying to add validation in a TreeView. Connecting to cell's 'edited' signal I can trigger validation on a cell input and if the field is not valid I reset it to previous value. That's not ideal, since the invalid value must be completely reentered while I'd like to leave it there. really It's pretty easy to do exacly what I want trapping a Tab on the editable, but that's junst *one* way to travel throught data (albeith very common). What I was not able to do is to prevent from moving from that cell, from within the 'edited' callback. I don't know how to stop any further processing of possible precedent events (click on other cell or DonwArrow or Tab...) Any hints?

[pygtk] Multi gtk.EventBox and gtk.Image cause artefacts
Hi everybody! I'm trying to write a tool in PyGtk that shows user lot of images in a Window, each images must be "clickable", so i've put all of them into a gtk.EventBox. The problem now for me is, when the number of images is more than about 45 EventBox shown in the main Window, i got some strange artefacts near to the last image has been show. How can i fix those artefacts from EventBox ? and keep my images clickable ? Here the link to my code;glade and image : http://www.filefactory.com/file/a02c6df/n/multi_eventbox_example_zip Please if someone can help me on this. Thanks a lot.
