Re: [pygtk] Splitting things up
Elver Loho wrote: Hi! I'm a PyGTK newbie. I built a small (less than 1k lines) PyGTK-based application back in 2006 that used SQLObject and was basically a simple GUI for editing things in a MySQL database table. It was a mixed experience for me. On the one hand designing a GUI with Glade was damn great and getting things done with PyGTK was surprisingly easy even back then. (I've noticed that you've improved a lot in this department over the years! Nice!) On the other hand the whole application ended up being a single file, with all of the GUI stuff being done in a single, insanely large class. Is there a good design solution for splitting the window controller into multiple chunks? For example, I've been doing some iPhone programming recently and on the iPhone each application consists of a ton of different UIViews. Each UIView could take up either the whole screen or just a part of it. And many UIViews come with a UIViewController, which is a nice way of implementing view-specific behavior. So, for example, you could build a small form consisting of two classes, one inheriting from UIView and the other from UIViewController. Then you can easily reuse that form elsewhere, as part of a larger view, while keeping its internal logic in those two classes and only communicating with the bits outside of it when it makes sense. Is there a way of doing something like this with Glade and PyGTK? The project I'm trying to build right now will have multiple windows, but almost all of them have a shared component: a database browser panel consisting of basic controls (back, forward, current record ID, number of records, go-to-record text box and button, search box) and I'd like to put the implementation of this panel into a separate Glade file and a separate Python class, then include it as a component in different parts of the application. What would be the best way of doing that? Best, Elver Personally I don't use glade much. But here is my 2 cents worth. What you need to do is learn more about python classes, you can do almost anything with them. Another handy thing to learn about is creating custom gtk+ signals for your gtk sub-classes. So you can 'connect' to them. Used right they can make your sub-classes much easier to code and use. Take any shared code, put that into its own class and just import it into any modules that need it. You could also put each of your windows into its own class (in its own file) I think it would be a good idea to create a new class for your database panel in a separate file. Using some gsignals to signal when the forward/backwards etc. buttons have been pressed. Plus take any gtk widget or dialog that has any resonable amount of code associated with it.. sub class it and put all the code for handling that widget in that new class. Depending on the size of the resulting class you can ether leave it in the same file or put in a new file. Also you can take the other stuff like your database handling code into its own class. Look for groups of functions, that handle similar objects or do similar jobs and put them in there own classes.

Re: [pygtk] gtk.ComboBoxEntry and changed event on keystrokes.
Osmo Maatta wrote: Hello, I have a small application that has a search-field (gtk.ComboBoxEntry) and a button to start a search job. The application will start a new search if user: 1) Selects an item from the gtk.ComboBoxEntry's drop-down list. This is handled by gtk.ComboBoxEntry's changed event. This is Ok. 2 Types a search query (some text) and presses the [Start search] button. This is handled by the button's clicked event. This is Ok. 3) Presses the [Enter]-key. This is handled by the combo's activate event attached to the gtk.Entry. This is Ok. Because a search-job can take quite a long time, I do not want to activate search for each keystroke, when user types text in the search field. And this is my problem. Key-strokes activate the changed event on the gtk.ComboBoxEntry field. I cannot distinguish between the drop-down list's changed event (which I want) and the changed event when user types text (I try to avoid this event).

Isn't the third parameter to pack_start ignored anyway if the second one

No! the prototype is :
def pack_start(child, expand=True, fill=True, padding=0)
So to set 'fill' to False you need at least 3 arguments.
I don't understand.
http://www.pygtk.org/pygtk2tutorial/sec-DetailsOfBoxes.html:
The fill argument to the pack methods control whether the extra space
is allocated to the objects themselves (True), or as extra padding in
the box around these objects (False). It only has an effect if the
expand argument is also True.
In the above line you set expand to False, so you don't have to provide
a value for fill, IMO.
That appears to be the fact. But I still prefer to specify both
'expand' and 'fill'.

This seems to get rid of the spacing between the label and spin
button -- but why?
It doesn't. It just sets the spacing of the widgets.
The code box = gtk.HBox(spacing = 10) would do the same thing.
The spacing is the same in both versions, you changed the 'homogenous'
parameter.
No! The default is for 'homogenous' is False. So technically you
don't need to specify it.

It (and its mate further along) are there to use up the available
space in 'box' to make the other widgets as small as possible, and to
thereby cause them to be centralized.
Uh, I think I see. So the only way to center something in a box is to
add an empty element on both sides with expand=True?
It is the only way I have found.
As another thing, there is an easier way to create the buttons in the
make_button_box() function.
for (name,number) in [
('INIT',1),
('PULSE ON',2),
('STORE',3),
('ANALYSIS',4)] :
button = gtk.Button(name)
button.connect('clicked', self.blub, number)
box.pack_start(button, True, True)
The buttons of course call different functions in the real code, this
was just to simplify the example.
Ok! but you could put in a function like.
for (name,function) in [('INIT',self.on_init_clicked),
('PULSE ON',self.on_pulse_clicked)] :
button = gtk.Button(name)
button.connect('clicked', function)
box.pack_start(button, True, True)
Its just a coding preference, instead of have many pieces of code
almost the same.

(The only problem left is that the buttons grow when the window is

If you don't want to have the button grow you will need to put another
HBox() around the current HBox() and add some empty labels each side
to center it in the window.
All the widgets are the same size on my layout.
But could you comment on a couple of your changes? I'd very much like to
understand what I was doing wrong, so that next time I don't have to ask
but can create the layout myself...

You cannot add a GtkWindow to another GtkContainer, a GtkWindow is a
toplevel-only
widget and is not meant to be maintained.
You can either:
- Manually unparent your window's child and add that child to the
notebook (the traditional oldschool way)
- Use the root argument to glade_xml_new or some equivalent
gtkbuilder api (I think that works
for building of sub-portions of the glade file)
- Use development or trunk versions of Glade allowing you to use
non-GtkWindow toplevel project
widgets - and use GtkBuilder that will allow you toplevelless
glade files without errors/warnings.
Cheers,
-Tristan
One thing I have done that is similar is, to not attach the window,
but attach the most top level widget. When designing the window, you
need to put all the widgets in a HBox,VBox or Table. Attach this not
the window itself.

Re: [pygtk] ScrolledWindow TextView Problem.
Dominic Salemno wrote: Greetings, Here resides my issue! I have a ScrolledWindow being utilized inside my application. Contained inside of the ScrolledWindow is a TextView widget. Last, but certainly not least, is a TextBuffer associated with the TextView widget. Simple... correct? I thought as much! The main purpose of the application is to provide a scrolling effect anytime new text is inserted. The window would start scrolling downwards in the event the text started scrolling outside the viewable area. I implemented this technique inside the pygtk FAQ: http://faq.pygtk.org/index.py?req=showfile=faq14.010.htp The technique is basically explained as so (copied from the entry): end_iter = text_buffer.get_end_iter() text_buffer.insert(end_iter, text) text_view.scroll_to_mark(text_buffer.get_insert(), 0) This works fine until one touches the viewable area in where the text resides. The TextView properities are as follows: set_editable(False) set_cursor_visible(False) Therefore, no one is actually editing anything inside this area.

Thanks for that. I didn't know about the add_accelerator() function.
I found the gtk.accelerator_parse() function, once I found out what
to parse (e.g. ALTLeft) it didn't take me long to get everything

Re: [pygtk] TreeView - Making whole row colored
Stephen George wrote:
Hi,
I am trying to get a treeview (with liststore model) to display rows in
different colors based on content in the list.
From what I've read in GTK+ 2.0 Tree View Tutorial - Tim-Philipp Muller
( c code based)
The most suitable approach for most cases is that you add two columns
to your model, one for
the property itself (e.g. a column COL_ROW_COLOR of type G_TYPE_STRING),
and one for the boolean flag of
the property (e.g. a column COL_ROW_COLOR_SET of type G_TYPE_BOOLEAN).
You would then connect these
columns with the foreground and foreground-set properties of each
renderer. Now, whenever you set
a row’s COL_ROW_COLOR field to a colour, and set that row’s
COL_ROW_COLOR_SET field to TRUE, then
this column will be rendered in the colour of your choice. If you only
want either the default text colour or one
special other colour, you could even achieve the same thing with just
one extra model column: in this case you
could just set all renderer’s foreground property to whatever special
color you want, and only connect the
COL_ROW_COLOR_SET column to all renderer’s foreground-set property
using attributes.
Which I've implemented as attached.
The setting of foreground seems to be working (half list blue, half red)
However my implementation seems to be ignoring the foreground-set flag.
I am expecting to ONLY see my 'special' foreground color when the
modified flag is also set to true, and grey/black writing when the
foreground-set flag is False.
I can get grey writing by setting the foreground to None, but I don't
belive this was the intent of the above description.
Am I mis-understanding how this functionality should work, .. or made
some errors in my code?
Thanks for any suggestions.
Steve
Hi Steve,
I can't see the pattern in why the colors are how they are. I think
some of the trouble has to be with some 'foreground-color' set as None.
It would probably be better to not use the 'Modified' column to affect
the color, and just put the color you want the row in the
'foreground-color' column (i.e. red,black or blue) and change the
set-up to.
column.add_attribute(mycell, 'foreground', COLUMN_FOREGROUND)
mycell.set_property('foreground-set', True)
If you must stay with this set-up, this function seems to do what you want
def _cell_data_func(self, column, cell, model, iter):
(modified,foreground) =
model.get(iter,COLUMN_MODIFIED,COLUMN_FOREGROUND)
if foreground == None : foreground = 'black'
if modified :
cell.set_property('foreground',foreground)
else :
cell.set_property('foreground','black')
cell.set_property('foreground-set',True)
return False
And use column.set_cell_data_func(mycell, self._cell_data_func) to
set it up.

Re: [pygtk] Formatting floats in treeview

If you put a float in a treeview, you get a really long decimal, which

lambda column, cell, model, iter:
cell.set_property('text', '%.1f' % model.get_value(iter,
column.get_sort_column_id(

GtkTreeViewColumn::get_sort_column_id() to get the column number,
which only works if the column is sortable. Can anyone tell me what
to do if I want the formatting to work on any column, not just
sortable columns? Thank you.
I use a text renderer with a right justify setting. And convert the
float to a string for the model. That way I can have any number of
decimal points I feel like.
right = gtk.CellRendererText()
right.set_property('xalign',1.0)
column = gtk.TreeViewColumn('number',right)

Re: [pygtk] Blocking main loop during execution of external program
Vláďa wrote:
Hi,
I'd like to ask you for help with solving my problem. First I'll try to
describe what I'm doing:
I have a PyGTK application which needs to run an external command. I use
subprocess.Popen to do it. Then I run a gtk.Dialog (saying Please
wait) and wait until the process is finished. After the external
process finishes I close the dialog and the program continues. So far
everything works fine. But now I want to change it a little. After the
process is finished, I want to return to the main loop but keep the
dialog opened. Then process results of the external program and run the
external program again. Repeat this a couple times and then finally
close the Please wait dialog.
I found out that I can return back while leaving the dialog opened by
calling dialog.return(0). But when I run the dialog again with
dialog.run(), Python (the interpreter) crashes. What is the problem? Is
it impossible to run the same dialog twice? What else could I do?
I need to block the main program loop because it can't continue before
the external program finishes. At the same time I want to have a pop up
window with a Cancel button (the window must be responsive). I'm
afraid I'm not experienced enough to use threading, which would be
probably best suited for this task. What would be the most simple way to
solve my problem?
I hope it is clear what I'm trying to do. Unfortunately my English is
far away from being perfect. If a code sample would help, I can post it.
Best regards,
Vlada
Have you tried to do it with a non-blocking dialog ?
Using
dialog.connect('response', callback)
dialog.show()
If you want to temporaly remove the dialog use
dialog.hide()
And when finished use
dialog.destroy()

Hi, folks!
Sorry if this question seems silly, but I am rather new to python and a
total newbie regarding Gtk programming, I googled a lot for a solution to my
problem and couldn't find something that worked for me.
I created a GUI using Glade, which contains a FileChooserButton. On startup,
this FileChooserButton displays the default folder for the application, and
a list of text files contained in this folder is loaded and presented in a
TreeView. My idea is, everytime the user chooses another folder using the
FileChooserButton, the application automatically loads the list of text
files in this new folder and refreshes the TreeView to show this new list.
In order to do this, I connected some code to the current_folder_changed
signal of the FileChooserButton, as in
(...)
self.btnPasta = self.wTree.get_widget( btnPasta )
self.btnPasta.connect( current_folder_changed, self.mudarPasta )
(...)
However, when I use the FileChooserButton btnPasta to choose another
folder,nothing happens. I made some tests and it seems that the function
mudarPasta is not executed at all. This function is defined inside my class
(as other functions that are executed by other signals of other widgets and
called as self.function_name):

Is this a feature, bug or my fault? Hot to create a label with

First you have to tell the label to use Pango markup:
self.label.set_use_markup(True)
Then you have to specify a readable size since numerical sizes are in
thousandths of a point - see:

The way I do it is, I have a function like.
def hide(self, dialog, event) :
dialog.hide()
return True
And in the init I use the command
dialog.connect('delete_event', self.hide)
I am not using glade thou, but this should work.
OK, the key being to return True so that other handlers (such the built-in
one that destroys it) don't get run?
How do you ensure the dialog isn't visible when the application starts?
I don't use glade. When I build the requester (in my init code) I just
don't do a dialog.show() call. That is done latter when I want to see
the requester.
One thing to remember is the dialog variable needs to stay valid for
the entire time the program is running (e.g. a global).
But as far as I remember when you start your glade app, it shouldn't
auto show the dialogs ether.

Re: [pygtk] Dialog Lifecycle?
Darren Hart wrote:
I'm trying to add a dialog bound to a menu item. I created the UI in
glade. I use the glade.XML.get_widget() to get the dialog, and then show()
it from the menuitem action handler. Then I hide it when the dialog
response handler receives RESPONSE_OK. If I CLOSE the dialog however (from
the window manager X button) I see gtk.RESPONSE_DELETE_EVENT, and after that
I can no longer use glade.XML.get_widget() to retrieve my dialog. It has
been destroyed.
1) Is it really necessary to destroy and recreate the dialolg, rather than
just show/hide?
2) If so, is the only way to recreate the dialog to re-read the glade file,
passing it the dialog name as the third param?
Also, the dialog is visible by default, so part of my start -up sequence is
to hide it but you can see the wm animation... so I don't think that is
the right way either.
I get the feeling I'm swimming upstream here, so if someone can set me
straight on how to properly use dialog boxes, I would be most appreciative.
Thanks,
Hi Darren,
The way I do it is, I have a function like.
def hide(self, dialog, event) :
dialog.hide()
return True
And in the init I use the command
dialog.connect('delete_event', self.hide)
I am not using glade thou, but this should work.

Hello,
I'm writing a little app that needs 2 windows, a main window, and

dialog,
and is modal.
My problem is that i want the second window displayed when i
click in a
button in the main window, and then, when i press Close in the
second
window, get the text and do some things, and update the main window
status bar.
I dont quite understand you here, it doesnt sound like a threads
issue,
more a design issue.
When I want to return stuff from a dialog I typically create my own
dialog subclass [1] which returns a tuple of the dialog specific
information from the (overridden run method). For example (excuse
broken
pseudocode)
class MyDialog(gtk.Dialog)
def __init__(self, setting1, setting2, setting3)
#call super
#save old settings
self.oldsetting1 = setting1
...etc
#construct dialog
self.widget1 = gtk.Entry()
self.widget1.set_text(setting1)
...etc
def run(self):
if gtk.Dialog.run(self) == gtk.RESPONSE_OK:
setting1 = self.widget1.get_text()
setting2 = self.widget2.get_text()
setting3 = self.widget3.get_text()
return setting1, setting2, setting3
else:
return self.oldsetting1, self.oldsettin2,
self.oldsetting3
then run it with
dialog = MyDialog(a,b,c)
a,b,c = dialog.run()
dialog.distroy()
Well, I've subclassed gtk.Dialog as you point, and I'm still having
the
same issue.
I run the dialog, enter the data and click OK. Then it was supposed to
hide the dialog, and update the statusbar while things are happening,
but in fact the gui freezes till the end.
Dialog.run() is the problem.
From
http://www.pygtk.org/pygtk2reference/class-gtkdialog.html#method-
gtkdialog--run
The run() method blocks in a recursive main loop until the dialog
either emits the response signal, or is destroyed
To get the behavior you want, you need to set up a callback for the
OK button which fetches the text and performs the desired action.
The related code is here:
http://pastebin.com/mb2ea398
And a screencast of what is happening in here:
http://www.infinicode.org/code/out.ogg
Any idea?

Hi Neil, I think your problem steams from the line dialog._model = gtk.ListStore(object) Which I think should be more like dialog._model = gtk.ListStore(str,str,str) However this does not give you the dynamic nature you desire. I don't know the limits of column expansion/contraction you require for your problem, .. but I see in your code you want to limit it to 20 (are they always strings?, or all columns the same type?) I would create a listStore with 20 str as arguments. I would then create the treeview with as many columns needed for the problem at hand Attached you will see a modified prog that works for me, I limited the columns to 7, each time you press the dialog button, a list is dynamically generated with a random number of columns. Assumptions: the list is always strings. length of list correlates to number of colomns to view. Don't know if this has been helpful? Steve Hi Steve, Thanks, that does do what I want. :) After posting I found out that, that line was the trouble, but I couldn't find a decent way of handling the problem. I didn't realise you could specify more types when creating the gtk.ListStore than you had intentions of using. I think it would be handy to be able to use a list or truple to specify the types as well.
