Re: [pygtk] Arabic text display problem
Tor Lillquist found the issue, it was the GTK runtime I was using (gladewin32.sourceforge.net) that was not built with win32 Uniscribe support. I tried his build and it did not have this problem.

[pygtk] Controlling a menu structure from an XML file?
Hello, I'm wondering about defining a menu structure using gtk.UIManager and an XML file. What confuses me a bit is that it seems to be necessary to define which menus and submenus I have in the Python code, even if I can then control their contents from XML. The reason seems to be that everything has to have an action. I define a menu like this: menu action=actionsmenu menuitem action=Select/ menuitem action=Run/ /menu But for this to work I have to write (somewhere in my Python code) menuAction = gtk.Action(actionsmenu, _Actions, None, None) ... just in order to translate the identifier actionsmenu into the label _Actions. I'd like to be able to write something like menu label=_Actions so that I can define the whole menu structure in one format in one place. Is this possible in some way?

[pygtk] liststore (ComboBoxEntry) alignment (justify)

I want to create a ComboBox by using the liststore object. my issue is that I want to set the alignment (justify) of the text in the combobox to right, how can I do that? 2. In addition, I want to to head default value to the liststore to show it as default in the combo box, something like == Choose from List ==. I can add it to liststore but how can I show it by default in the combo box? 3. It is posible to add icons next to the text in the ComboBox? if yes how can I do that?

I don't believe it's possible and for good reason. A major benefit/feature of UIManger is making actions independent of any given widget, e.g. a menu item. When the notion of separated actions and widgets introduced you can then combine them at will without having to keep multiple widgets in sync. One reason I switched to UIManager was the all too common scenario where an icon or label was modified in one part of the UI but other parts of the UI (e.g. the same item in a popup menu or a toolbar button) was forgotten about in the update leading to inconsistencies in the UI. I really like the fact I change the definition in exactly one place and every part of the UI is consistently updated. That flexibility and consistency occurs because actions and widgets are independent. -- John Dennis [EMAIL PROTECTED] Learn. Network. Experience open source.

You first need to declare what you want the liststore to contain. e.g. To create a liststore which will hold a pixbuf and string liststore = gtk.ListStore(gtk.gdk.Pixbuf, str) Create an image to be added to the liststore. image = gtk.gdk.pixbuf_new_from_file(/home/user/image.png) Append the created image and a string to the liststore. liststore.append((image, Some Text)) The append method requires a tuple or a list which contains the items to be added to the model. We now need the combobox to use the model we created. combobox.set_model(liststore) We now need to render the data we have in the model. We create a gtk.CellRendererPixbuf() for our image and a gtk.CellRendererText() for our string. px = gtk.CellRendererPixbuf() text = gtk.CellRendererText() Pack the cell renderer into the combobox. combobox.pack_start(px, False, False) combobox.pack_start(text, False, False) Use the add_attribute method to specify which column in the model the CellRendererPixbuf() will get values from. combobox.add_attribute(px, pixbuf, 0) Do the same for CellRendererText() combobox.add_attribute(text, text 1) The first parameter for the add_attribute method specifies the cell renderer to use. The second parameter specifies the attribute of the cell to be used to get its value. The last parameter specifies which column in the model the cell renderer will use. To align the string to the left, i would use combobox.pack_end(text, False, False) To set a default choice in the combobox, i would use combobox.set_active() to set the default choice in the combobox.

Your citation was what I was looking at, but I didn't understand that I needed to replicate so much. Wow, it's really complicated subclassing in GTK. I still don't understand what to do if my widget is composed of other widgets (rather than Cairo drawing and text). A simplification of what I am trying to do is to create a widget with two buttons. I guess that I need to do something different in do_expose_event and do_size_request, but I'm not sure what. To begin with, it isn't clear to me what the do_ methods are. Do they override event handlers in the abstract Widget class? I don't see documentation for them there. I tried calling do_realize and do_expose_event on the button, but those calls fail (although the methods apparently exist). -- Jeffrey Barish ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Normally, you just use boxes or something else to align those widgets.
Or subclass e.g. gtk.HBox. However, if you feel adventurous, you can
play with this incomplete but working example:
import gobject
import gtk
class CustomContainer (gtk.Container):
def __init__(self, child):
gtk.Container.__init__(self)
self.__child = child
self.__child.set_parent (self)
self.set_flags (gtk.NO_WINDOW)
def do_size_request (self, requisition):
requisition.width, requisition.height = self.__child.size_request ()
def do_size_allocate (self, allocation):
self.__child.size_allocate (allocation)
def do_forall (self, include_internals, callback, user_data):
callback (self.__child, user_data)
gobject.type_register (CustomContainer)
window = gtk.Window ()
window.add (CustomContainer (gtk.Label ('test')))
window.show_all ()
window.present ()
window.connect ('destroy', lambda window: gtk.main_quit ())
gtk.main ()
