[pygtk] Combobox error? duplicated columns
Hi
I'm not sure is this is an error -- but when I attach a ListModel and
and CellRenderer to a gtk.ComboBox I end up with duplicate columns in
the list box. Attached is a small screenshot.
This only occurs if I have first opened the combobox list editor in
glade and then saved.
Glade inserts an empty items property in the xml:
property name=items translatable=yes/property
Removing this element fixes the problem. The code below replicates the problem.
Is this a bug and should be reported on bu

[pygtk] Toolbar layout button to right
Hi, I'm having trouble packing a toolbar. I require a toolbar with 3 buttons packed to the left and one that is always on the right. As illustrated below. [Button1__Button2__Button3__Button4] Packing the three to the left is ok. This is the default behaviour of glade when constructing the toolbar. My question is how to have the right button (button4) on the right hand side. I tried adding a ToolbarItem, with a HBox and the button in the the last hbox container. Running this does not work - even though glade shows the button on the right hand side. Any suggestions: Thanks -- Edward Stow ___ 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/

Re: [pygtk] Toolbar layout button to right
Hi again, Glade does not appear to set the expand property on toolbar items ... can this be verified? Using glade 3.2.0 -- setting the packing expand option to Yes appears to have no effect - when the ToolItem is created by gladed the expand property is False. Note that the Glade UI shows that the item has been expanded in the UI builder but when running the application the item is not expanded. Or am I just missing on some other option to be set.

Re: [pygtk] help with two main windows in pygtk

I have made two Windows (main_window, new_company) and saved them within the same galde file and loading them using libglade (?) I have a button in the main_window which when clicked should show the new_comany window (within a vbox in the main window). I am not sure how to implement this using pygtk. Should I make a different class and different file for each Window ? This is going to be fairly big application. And how to load the the new_company window within a vbox in the main_window. This is the signal handler for the button click in the main window(mwglade). vbox_main is the vbox. new_comp_glade is the window for the new company. def new_file(self,widget,data=None): New data file self.new_comp_glade = self.mwglade.get_widget(new_company) self.vbox_main = self.mwglade.get_widget(vbox_main) self.vbox_main.add(self.new_comp_glade) I'm not sure what you are trying to do exactly but adding a gtk.Window to a widget is not going to work. Consider adding the container (VBox, or HBox ) that is the child of the window And I know that you cannot add a widget that already has a parent. So consider unparent() 'ing the widget that you are adding to the vbox. self.new_comp_glade = self.mwglade.get_widget(new_company) self.vbox_main = self.mwglade.get_widget(vbox_main) child = self.new_comp_glade.get_child() if child: # remove the child from the top window self.new_comp_glade.remove(child) self.vbox_main.add(child) This gives seg fault. Am I doing something wrong here since this is not making sense. I know I have messed up somewhere. ___ 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/ -- Edward Stow ___ 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/

It works :) Thanks a lot !!! I am making a small financial app in pygtk (gpl) glade file : http://rapidshare.com/files/93713518/main.glade.html I have a =MainWindow= window (hbox: menubar, statusbar, a central main area where all the stuff is displayed) with a menu item called create company. On clicking create company - it has to open the =CreateCompany= window in the central main area. I have made different windows for vouchers/reports. For every action it will load the windows in the central main area. I dont know whether this is the rightway - I just took a guess. Also should I use seperate python files for each gtk window or how is it done ?? I use one glade file that contains many top level windows - each top window contains a child container that is reparented as needed. Each of these containers is represented by a View class (a python class,) each View subclass knows how to initialise the view, populate widgets with model data, and respond to events. I keep each view class in a separate *.py file. Whether this the 'python way' I don't know. Suggest you read up on Model View Controller / Model View Presenter patterns.

[pygtk] GObject signals subclassing
Hi I am creating a custom subclass of gtk.Widget and was looking for better documentation on creating custom signals. I have located the tutorial [1] on subclassing gobject and the pygobject reference documentation [2]. 1. Could somebody point me towards reference documentation for __gsignals__ class variable? 2. The subclassing gobject toturial[1] suggests that you use __gobject_init__() if you are subclassing a derivative of gobject as calling the derivative__init__() will overwrite your custom properties. I assume that this does not apply to custom signals defined in __gsignals__ ? I could not detect any negative effects in my subclass of gtk.Widget 3. Class closures. I was looking for a better explanation of the GObject class closure methods. Eg from the signals.py source in the gobject source. def do_my_signal(self, arg): print C: class closure for `my_signal' called with argument, arg This method only appears to be a callback method for the 'my_signal' signal -- does it have any other purpose? The tutorial also suggests that class closures are optional. Under what conditions are they needed? It would be useful to link the gobject tuturial from the pygtk.org site.
