Re: [pygtk] ANN: PyGUI 2.1.1
I'm disappointed that I appear to be the only one on this list that finds these announcements objectionable. And contrary to speculation I find them all objectionable (yes that means yours as well Roberto). So far it's been lucky that not all of the hundreds of projects based on pygtk have felt it necessary to send announcements to the list and I thank them for their restraint. I would suggest that an announcement only maillist be setup for those who wish to send and receive these announcements but I fear that many would continue to spam this list anyway.

So making PyGUI emulate pygtk wouldn't make sense from my point of view. I certainly don't mean to dissuade anyone from using pygtk. If you like it, by all means continue to use it. OK, that's more diplomatic. My opinion is that if you create a mailing list for PyGUI (and I suggest Mailman [0], the software running this mailing list, for it), a message if anybody is interested in a different approach to pygtk, a PyGUI mailing list has been created at this address on this mailing list will cause no complaints (notice your first email didn't mention pygtk at all). I have to disagree. I consider attempts to build a competing community by spamming maillists with announcements to be annoying and rude. The criterion should be does this post add value to the community.

Re: [pygtk] Saving and reading images from database
Timo List wrote:
My program uses the SQLite database. The database holds some
information about persons and I want to add a picture for each person.
Not the path to the file, but the actual image so that the image also
works if the file is deleted on the harddisk.
I can save the image in a BLOB column as:
imgfile = open('/path/to/image.png')
db.save_image(imgfile.read())
Works fine as far as I see. (Maybe any comments on this?)
Retrieving also works, but I see no possibility to show this image in
a gtk.Image widget. I can't seem to find anything related to this on
the net, maybe someone reading this has done this before?
One possibility is to save the image as a compressed in-line image in
the db and create a pixbuf from the in-line data after it's retrieved
and decompressed. Here's some code to create an in-line image and
compress it:
import struct, bz2
...
# pb is a pixbuf containing the image to be in-lined
pix = pb.get_pixels()
inline_img =
'GdkP'+struct.pack('!iBBHiii',len(pix)+24,1,1,pb.get_has_alpha()+1,
pb.get_rowstride(),pb.get_width(),pb.get_height())+pix
bz2_inline_img = bz2.compress(inline_img)
# save bz2_inline_ob in the db
To use the compressed in-line image use something like:
# the compressed in-line image is in bz2_inline_img
inline_img = bz2.decompress(bz2_inline_img)
pb = gtk.gdk.pixbuf_new_from_inline(-1, inline_img, False)
Copy the pixels if you are going to delete the inline_img string.
Then you can use the pixbuf to create your image.

Re: [pygtk] Disable signals and events to use a button as a container, not as a button?
Have you tried using an eventbox inside the frame to hold the vbox that holds the other stuff? I believe that the purpose of the eventbox is to do just the kind of thing you want i.e. set the bg_pixmap for the eventbox to some custom pixmap that represents your style. John Ryan Martin wrote: That's a good question. I didn't explain why I needed to do this because I thought I'd confuse more. In the software I'm writing, I'm combining theme elements with some widget tricks to accomplish a visual task that I don't know is possible by any other means. I need to have a container than I can 'skin' that can contain other widgets. My initial thought was to theme gtk.Frame to have borders and a background (like a button), and I can pack all of my widgets into that. Unfortunately, to my knowledge, you can't have a background on a frame widget. So I started cycling through other gtk widgets to see if there was some sort of container that I could theme, but was unable to find something that worked. (http://www.ensomniac.com/pygtk/button_example2.jpg) That led me to my latest theory, that if I were able to use a button as a container, I could theme gtk.Button to get the visual style I wanted, but also the functionality of having the widgets inside. I would need to disable the core button (container) from receiving and processing signals, but somehow pass them on to any of the widgets inside the button: (http://www.ensomniac.com/pygtk/button_example.jpg) And that leaves me where I'm at now. The following code will disable my base button from working: *print* self.widgets.main_container_button.get_property(above-child) *False** print* self.widgets.main_container_button.set_property(above-child, True) *print* self.widgets.main_container_button.get_property(above-child) *True* But I have no idea how to pass the events to the widgets that are children of the button (the 'button_2' widget and the entry widget in the image above). If there is some other way to accomplish my task, I'm all ears. Currently, I'm struggling trying to get my events passed to the child widgets. Thanks for the help!

Re: [pygtk] Animation performance - limitation or my code?

I once wrote a gtk program in C that displayed about 30 animations on a
drawing area and they moved around the screen, and performance was
excellent. The drawingarea size was 1600x1200 and the animations were

I have started to write a similar app using pygtk in a more object
oriented way, and the drawing area size really seems to have a large
impact on performance. When the drawing area is 100x100, anims are
smooth. If the drawing area is dragged to 1000x1000 the frame rate drops
very quickly. Is this to be expected with the python being interpreted,

Look at the TreeModelFilter. With the right set_modify_func() function you may be able to massage the look for your purposes. Thanks for a hint! I've managed to create a 1:1 mapping between filtered and original model - but I don't see how to change the row hierarchy in the filtered model. It seems to me it is not possible to do anything else than setting a value for filtered model's cell and thus using PyGTK's native tree sorting mechanism over the filtered model won't work. Did you mean I can reorder the filtered tree rows as if they were sorted by a given column (with original model's hierarchy that doesn't respect my re-ordering) and then hide the expanders? That would also mean I have to maintain a path-to-path/row-to-row mapping for every tree row and every column I want to sort-by. Mapping example for sort by Priority: tree - sorted flat list (0,) - (0,) (0,0) - (1,) (0,1) - (3,) (1,) - (2,) Do you have any tips for the mapping? If I use something like the example before I have to go through most of the tree and re-number the paths with every row insert/delete (but finding the right path is easy). Or I could store pointers like iterators or row references for every row and every sortable column - they wouldn't need any additional care in case of row insert/delete. But the iterators are not guaranteed to be persistent and large number of row references would slow down the tree to crawl... That looks like having two copies of all data (a tree and a list) doesn't help either because I would have to maintain the path-to-path mapping anyway (or compute it on a fly by walking through all tree rows, counting the rows traversed and searching for a particular hierarchy number - which is too slow, O(N) for N=number of tree rows). I can also imagine a hybrid solution where every parent tree node keeps a number of nodes in his subtree which would speed up the tree traversing to something like O(log N) but would also add O(log N) operation of re-calculating the counts in a part of subtree on every row add/delete. From what I've thought about so far it seems the easiest way would be to hack into the TreeModelSort and add a property that would control if the rows compared during the sort operation will respect the hierarchy or if every row in the model gets compared. Can it be done directly from Python or will I have to roll up the sleeves and dive into the C code? Are there any tutorials available? Thanks for any further ideas! I think that you have to use a ListStore instead of a TreeStore and then work out some way to simulate a hierarchy with hiding children which I imagine is the major benefit of using a TreeStore.

This is what I have so far... http://pastebin.com/m6d3eb0b9 (The toggle buttons and text view are part of a glade file) For one, if there isn't text selected and the bold, italic, or underline button is pressed, I tried to apply the tag (buffer.apply_tag_by_name) by using the cursor's position as the start and end gtk.TextIter, although it seems to do nothing, as any text I type after I apply the tag is still in the same font as before.

(If text in underscores is bold) _This is bold te_ (But if I keep typing, the formatting isn't kept) _This is bold te_xt (It should be like this) _This is bold text_ I found a rich text demo application in Pygtk while I was searching for a solution (http://www.mail-archive.com/pygtk@daa.com.au/msg10283.html), but that one has the same limitation as mine. (Tags are not applied to text added directly after a section with the tag applied) And lastly, when the cursor is at the beginning of a block of text with an applied style, the gtk.TextIter at the cursor position says that the tag for the style is applied, but when I type it shows up in the default font ( '|' is the cursor) |_ere is bold text_ (iter.get_tags() has the bold tag, but when I type something...) h_ere is bold text_ (The tag is not applied) Why does it say that the bold tag is applied at the cursor if it doesn't apply the tag to text typed at that location? I think I might be missing something fundamental about how tags work... _ I'm sorry if any of this was unclear. If anyone could point me in the right direction I would be grateful. =) Your application will have to handle the bookkeeping required to manage the tags in the TextBuffer. When text is inserted at the cursor your app has to catch a signal indicating the text is being inserted and then apply the required tags to the inserted text. I think this can be done by catching theTextBuffer insert-text signal (using connect_after() to make sure the text has already been inserted) and then applying the tags to the text in the callback.

Re: [pygtk] synchronizing HPaned widgets
Stephen Langer wrote:
Hi --
I'm hoping that someone can tell me if this is a bug or if I'm doing
something wrong.
I have two HPaned widgets whose separators I'd like to keep
synchronized. Both Paneds are in the same VBox, so they have the same
width.
As described at http://faq.pygtk.org/index.py?req=showfile=faq19.013.htp
, I connect to the 'notify' signal for each pane to find out when the
separator has been moved. The callback function blocks the signal for
the other pane, changes its position to match the first pane, and
then unblocks the signal.
The problem is that the signal doesn't seem to be blocked sometimes,
so the program goes into an infinite loop. There are easy workarounds
for this, but they're ugly and unsatisfying. In particular, the
program loops when the panes are first shown if the contents of two
diagonally opposite subpanes are larger than the contents of the other
two.
I've appended short program that illustrates the problem. Just
starting the program will put it into an infinite loop. If you
replace paneMoved by paneMoved_workaround, the problem goes away.
Why doesn't blocking the signal work? Am I doing something wrong?
I've run this test on OS X with python 2.5, gtk 2.14.7, and pygtk
2.12.1, and on Linux with python 2.4, gtk 2.8.20, and pygtk 2.8.6.

Why isn't calling handler_block before calling set_position sufficient? -- Steve Yes but you have to set the default size of the window as large or larger than the required size of the largest pane. Your code doesn't set the window size so it starts up with the minimum required size to fit the paned widgets. Since the two separators can't line up because the panes are different sizes and because the panes can't shrink the set_position() calls fail and apparently trigger a resize calculation which trys to set the position and so on. Your choices are allow something to shrink or set a window size that will allow the separators to line up initially. Also you can add a detail to the notify signal connection that only signals when the position is changed - use notify::position and you can remove the gparamspec.name check in paneMoved().

Re: [pygtk] Treeview/model: Problems with Expanding and Selecting Rows
darethehair wrote: Hello Folks! The PyGTK tutorial example named 'basictreeview.py' works fine for me. When I click on the 'expander' arrow for a row, it instantly expands to show the child rows under it. In my case, I am using a 'lazy treeview' to only populate the child rows as I need to do so -- mostly because of time, but also because I want to allow unlimited 'nesting'. My problem is two-fold: 1) When I use a 'row-expanded' signal detector, I have to click two or three times on the 'expander' arrow in order for the child rows to actually show up. In fact, out of desperation I have even added the following to my routine to 'force' the issue: self.treeview.expand_to_path(path) self.treeview.expand_row(path, True) 2) When I add a selection 'changed' signal, it works, but it 'gets in the way' of my 'row-expanded' detector i.e. even if I am very careful to click just the 'expand arrow' on a row, it triggers my 'changed' selection routine the first time I touch a row. I would appreciate any tips to produce the desired behavior! :) Connect to the test-expand-row signal and add the rows in the callback. You have to put a dummy child row to get the expander to show and replace it with the real children in the callback.

Re: [pygtk] TreeView selection issue
Alan F wrote:
Hi
I am new to GTK programming. I want to create a program that displays
the sub-folders of a main folder in a tree view format. Once I find
the particular sub-folder , I want to be able to click on it to
display the contents of that folder. When the contents of that folder
is displayed, I want to click on any file to display the mp3 tags of
that file.
I have managed to get a program working that displays all the
sub-folders of the main folder as a treeview. The problem is I am
having trouble trying to get it to do the next step i.e. when I click
on a sub-folder I want to display the contents of that folder.
After googling around, I found a post that used a solution of adding a
button event to the treeview. I put it in an example code below and it
works but with a problem.
Firstly, to describe the actions of the example code, I've created a
treeeview that has 3 parents and 3 childs, when I click on a selection
(either parent or child), the value of that selection is printed in
the console.
The problem is that when I click on any selection, nothing happens.
When I click on it again, the value of that selection is displayed.
When I click on another selection, the value of the previous selection
is displayed. When I click on that selection again, the values are
displayed. On clicking on any selection, the value of the previous one
is displayed.
I've put console print statements throughout the code and the contents
are definately being displayed when I single click on selection. I can
only think it is something to do with the lines treeselection =
self.treeview.get_selection(), (model, iter) =
treeselection.get_selected().
I've checked the API and in TreeSelection there is text that may have
something to do my issue:
One of the important things to remember when monitoring the selection
of a view is that the changed signal is mostly a hint. That is, it
may only emit one signal when a range of rows is selected.
Additionally, it may on occasion emit a changed signal when nothing
has happened (mostly as a result of programmers calling the

I don't really know enough about GTK programming to understand where
to start to look to fix this. Can someone please point me in the right
direction?

PS: BTW, where did you find the stop_emission() method? I can't retreive it

it a gobject method:
http://library.gnome.org/devel/pygobject/stable/class-gobject.html#method-gobject--stop-emission
following the docs I have several questions?
1. the explanation is exactly the same as for emit_stop_by_name: which
is the difference?
They are the same.
The stop_emission() method stops the current emission of the signal
specified by detailed_signal
2. current emission means the emission of the signal that is now
handled? if this is the case, what's the need for specifying the name?
A signal could be emitted within a signal emission.
3. How is it different from returning True?
I tested it with::
b = gtk.Button(Press me)
e = gtk.Entry()
b.connect('clicked', self.on_clicked1)
b.connect('clicked', self.on_clicked2)
e.connect('key-press-event', self.on_key_press_event1)
e.connect('key-press-event', self.on_key_press_event2)
on_clicked2 cannot be inhibited returning True from on_clicked1 while
on_key_press_event1 *can* be inhibited simply returning True.
Both can be inhibited using stop_emission.
Some signals provide an explicit means of stopping the signal emission
using a return value from a handler. The clicked handler is not
supposed to provide a return value so returning True does nothing.

There is just a strange behaviour: once I have clicked on the blocked page

the 'switch-page' is not emitted anymore. I have to click on the current

It seems that the internal page_num var. is set to the new page. Blocking
the event just prevents to visualy switch to that page, but internally,
PyGTK thinks that he is on that page... I tried to use set_current_page(),

I don't see how that would happen. I guess a small self-contained

I haven't been able to solve this even with aid of google, the pygtk reference and the gtk C source, so pretty please help? I'm making an application that you can think of as an image viewer. I want to display a widget in a gtk.Viewport. The widget can have any size from tiny to humungous. I don't want the viewport to ever give the widget a larger size allocation than requested, and I don't want the viewport to ever resize to accomodate a large widget. It should rather leave grey areas around the widget/show only a portion of the widget. To do this I have subclassed gtk.Viewport (MyViewport) and overrided the do_size_allocate method: def do_size_allocate(self, allocation): self.allocation = allocation child_req = self.child.get_child_requisition() child_alloc = gtk.gdk.Rectangle(0, 0, *child_req) self.child.size_allocate(child_alloc) self.props.hadjustment.update(allocation.width, child_alloc.width) self.props.vadjustment.update(allocation.height, child_alloc.height) if self.flags() gtk.REALIZED: self.window.move_resize(*self.allocation) self.child.window() When I add a very large widget (a gtk.DrawingArea) to MyViewport only the originally visible portion of the widget is redrawn when I resize the window using the mouse, and the grey area around widget gets littered with grey lines that are not redrawn if you minimize and restore the window. I assume this comes from that the proper gdk windows haven't been updated, and that the grey lines are remnants of old Viewport borders. In gtk_viewport_size_allocate in gtkviewport.c, gdk_window_move_resize is called on three gdk windows: viewport-window, viewport-view_window and viewport-bin_window, but in pygtk I only have gtk.Viewport.window. I assume that this is the problem? If so, how can I fix this? Or is there something else that I have overlooked? And another relevant question: am I overcomplicating this? Is there some kind of flag that I could set on a vanilla viewport to accomplish this? I'm not sure what behavior you are looking for so I'll assume that you have one widget (e.g. Image) that you want to put inside a Viewport in a ScrolledWindow in a Window. I'll also assume that you want the widget to float in the center of the Window when the widget is smaller than the Window. Finally I assume that you want the widget to be partially displayed but scrollable within the window when the widget is larger than the Window. If these assumptions are wrong that ignore the following suggestion. If so then I suggest that you put the widget inside a Table of size 1,1 and attach it with EXPAND but not FILL. Put the table in a Viewport inside a ScrolledWindow inside a Window. This should keep the widget to a fixed size within the Window.

Re: [pygtk] Is the pygtk tutorial still being maintained?
Eric S. Raymond wrote: In the course of a recent project, I found myself consultung the pygtk tutorial and developed some updates abnd additions for it. I mailed one to John Findlay but received no response. Oops. Your email got buried until you reminded me of it. I have written documentation and an example program for the MessageDialog widget. Thanks. I have the following list of issues about the tutorial: 1. What is private tooltip data and how is it used. 2. The Toolbar request to add space is deprected. What should replace it? 3. Entire toobar section should be rewritten for new API. Yes there are a lot of sections of the tutorial that have become out-of-date and should be rewritten. I lost interest in maintaining the tutorial (and time) a couple of years ago due to other commitments, etc. I hope someone will volunteer to take up the challenge. 4. How can I set a single dimension on a widget to be fixed in the presence of resizes? I don't know of any easy way to do this. 5. What, exactly triggers the appearance of scrollbars with automatic policy? If I understand your question correctly I've assumed that when the window became smaller than the widget required allocation in a direction that the scrollbar would appear. I note that the last update was in 2006. Is this document still being maintained? Are the sources in a version-control system that I might get write access to? I think Gian answered this. You'd have to get checkin access (ssh) for svn on the gnone servers.

Re: [pygtk] setting a filter for gtk.FontSelection
Le Roux Bodenstein wrote: This feature was removed from gtk after 2.2. There should be a note similar to the note in the description of the FontSelectionDialog documentation. Aah thanks. So it is a bug in the documentation? I don't mind just using a normal widget and populating it with the right fonts. Any idea how to list and filter fonts so that you get all the monospace fonts on the system? I can't find it in the documentation. Retrieve the pango context from the main widget and then get the list of the font families in the pango context and filter them for monospace fonts e.g.: context = gtk.Window().get_pango_context() monofonts = [fam for fam in context.list_families() if fam.is_monospace()] John ___ 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] Pygtk does not play nicely with speech-dispatcher
James Simmons wrote: Michael, Thanks for the tip! It was a big help. I put gtk.gdk.threads_init() in the __init__ method of my program and I did get callbacks. It looks like I didn't get callbacks for every word, but Pygtk seems to not be the problem anymore. Thanks again, The problem is that gtk and by extension pygtk has an event loop, and the python speechd api has implemented its own event loop within a thread. The speechd protocol is synchronous and sounds similar to RPCs. This event loop conflict was in general a problem with RPC programming with GUIs. The best solution is to integrate the two event loops using io_add_watch but that would entail throwing away the python speechd api and you would not have to use threads. This is the course I would take if I was doing your project. If you want to use the speechd python api you have to make your pygtk program threaded and that is more than just calling threads_init. Others on this list can point you to a list of best practices for threading in pygtk.

Re: [pygtk] shrink property of gtk.Paned
Geoff Bache wrote: Hi all, Is there any way to set up gtk.Paned such that automatic shrinking on resize never occurs, but shrinking by manually dragging the separator is still allowed? As far as I can see setting shrink=False prevents both from occurring. If I understand your situation the default behavior should do this i.e. pane1 should have resize=False and pane2, resize=True which should allow resizing to apply all additional space to pane2 and none to pane1. A short example would help. John ___ 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] TreeView and CellRendererCombo - MS Access-like form behaviour
Stéphane Brunet wrote: John Finlay a écrit : Stéphane Brunet wrote: Hi, btw, thank you John Finlay for the answer on my last question. In my quest of a GUI interfacing my small database application (I did try OpenOffice Base and went mad after one hour :S ) I would like to copy some behaviour of MS Access in my forms. Say I have two (SQL) tables with two fields and one relation between the two: |Table1| |Table2| | Field1 (int) || Field1 (int) | | Field2 (str) | | Field2 (str) | Now in my PyGTK form of Table1 (a TreeView), when I display the Field1 in the first column, I would like to have a ComboBox which displays the text associated to the integer value of Table2 (i.e. Table2.Field2) rather than the value directly. However, I still want it stored as an integer in Table1.Field1. How would you do this in an elegant manner ? Do I have to create my own CellRenderer more generic than a CellRendererCombo ? How do you want the db info displayed in the treeview? I think of actually displaying the content of Table1 with Field1 in the first column and Field2 in a second column. However, Field1 wouldn't be displayed as an integer but as a string coming from Table2. In order to modify the content of Field1, I would like the user to select a string (of Table2.Field2) in a CellRendererCombo rather than an integer. Are you planning on inserting the table info into a liststore or generating it on the fly? I thought of using two separate ListStore to store the content of each table. I don't know if it is the best way but I want to alter the information in the DB only when the user has finished his modifications in the GUI. To set the value displayed in the first column you could use set_cell_data_func and then set the text in the associated function using the table1 field1 value to select the table2 field2 value.

Re: [pygtk] Checkbutton alignment

Hi all,
I got a checkbutton with a large label which is being wrapped into a

Is there a way I can set the vertical alignment of the checkbutton so
it remains in the top of its space if its label is too big (has many
lines)?
Here's an example.
As you can see when you run the code, the checkbutton stays aligned
vertically to the center of its space.
Can anyone help? thanks

This is the only way using the standard checkbutton. I suppose you could
subclass checkbutton and set its do_draw_indicator method to change the
behavior.
