[pygtk] how to add to a scrolledwindow?
Hello,
I've written very little pygtk ( no straight gtk), am stuck trying to
add to a vbox inside a scrolledwindow.
A minimal example is ...
import gtk
window = gtk.Window()
window.connect('destroy', gtk.main_quit)
scrolled = gtk.ScrolledWindow()
window.add(scrolled)
vbox = gtk.VBox()
scrolled.add_with_viewport(vbox)
def addbutton(window, event):
vbox.pack_start(gtk.Button('extra'))
window.show_all
b1 = gtk.Button('aaa')
b1.connect('button_press_event', addbutton)
vbox.pack_start(b1)
b2 = gtk.Button('bbb')
vbox.pack_start(b2)
window.show_all()
gtk.main()
I click 'aaa' but no 'extra' appears.
The actual application starts with a list of book authors as button
labels. Clicking on an author should insert the author's book titles (a
vbox of buttons) between this author the next. Also, it's for a Nokia
N900 really uses hildon.PannableArea etc.
Thanks for any help,
Brian Keck

[pygtk] Threading Question
Got some help last week in regard to a problem which put me on the trail
of understanding threading. Through reading and playing around I've this
working example. What I don't understand are how certain parts of it
work. BTW, I'm working on a windows PC.
import threading
import random, time
import gtk
#Initializing the gtk's thread engine
gtk.gdk.threads_init()
class FractionSetter(threading.Thread):
This class sets the fraction of the progressbar
def run(self):
progressbar.set_fraction(random.random())
print 'first'
time.sleep(2)
progressbar.set_fraction(random.random())
print 'second'
time.sleep(2)
gtk.main_quit()
def stop(self):
Stop method, sets the event to terminate the thread's
main loop
self.stopthread.set()
def main_quit(obj):
fs.stop()
gtk.main_quit()
#Gui bootstrap: window and progressbar
window = gtk.Window()
progressbar = gtk.ProgressBar()
window.add(progressbar)
window.show_all()
window.connect('destroy', main_quit)
#Creating and starting the thread
fs = FractionSetter()
fs.start()
gtk.gdk.threads_enter()
gtk.main()
gtk.gdk.threads_leave()
My question is:
a) What does putting gtk.main() between gtk.gdk.threads _enter
gtk.gdk.threads _leave actually do?
b) Am I right in thinking the time.sleep(2) are there so that the
progressbar is changed and the gui window is updated?
c) Without the time.sleep(2) I'm thinking the progressbar would be
changed but the gui window wouldn't be updated. Correct?
Still getting my head around threads. See all sorts of references all of
which seem a wee bit beyond my comprehension at the moment. Any comments
would be appreciated.
Thanks
Brian

The latter does drawing, and rereshing. That is why the program behaves as it does. The window outline appears but no inside until after 5 sec when the full window takes shape my name then appears. What I want is the full window appearing at the beginning and then 5 sec later my name appears. Make sense? What you want is clear to all, but the way you want it, is not going to fly. You cannot block in the thread of control that does 'gtk.main()' (well, you can, but it does not do what you want). There are 2 solutions to this: 1. start another thread to do your processing, and have it coummunicate with the gtk.main() thread to update the window. 2. do everything event-based. Instead of sleeping, start a timer, and attach 'print name' to the handler that gets called when it times out. I would recommend that you look at the tutorial (http://pygtk.org/pygtk2tutorial/index.html), in particular chappters 19, 20, and 24. The latter is an example. To understand those chapters you may want to do the entire tutorial. Since you seem new to event-based programming, it won't be wasted time, I think.

Re: [pygtk] Updating a window
Thanks for that. Do_stuff consists of things like: Impersonate a user Copy Db to c: drive Read sql DB and obtain PC settings Log-off certain types of users Change the registry Set printers inc default printer Write to a log file Etc So event handlers doesn't seem to fix the bill in my mind. Roughly speaking, the GUI window displays a message to the user. Periodically, this changes as the login script runs through it's tasks. Even displays a goodbye message on the occasions the user shouldn't be allowed to log in. When I used Perl, there was a window update function. Alas, I'm unsure of where to go now.

If I'm not mistaken. The iter becomes dead when the model is changed by

I know in our treeview use when we rebuild our data model we look for
the row data that was prevoiusly selected, then after the data is
reloaded we then select that row.

There are other ways of handling it as well, but that one works well for us. If you look around you will also find out how to autoscroll the text as it is added, among other things.

However it'll be a bit dirty, even if it works. We use to have the toggle packed into a column like that as well. If I remember correctly clicking anywhere on the row would always toggle the toggle. The other problem we had was that it would not always render correctly. The line spacing was wrong with rows overlapping I think. Then we added more columns with additional information as well as right mouse button popup menus. I would recommend you separate out the toggle into its own column. It will simplify things. Otherwise I think you will have to get mouse pointer coordinates and compute its position on your window... until you figure out if it was your toggle it was over. -- Brian [EMAIL PROTECTED] ___ 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/

Actually you can change the title at any time. In our specialized

hey there.
i have a gtk GUI app that uses 4 text views to update info from 4
different threads. the code i use to update the view is this.

if self.buffer.get_line_count() 400:
self.buffer.delete(self.buffer.get_start_iter(),

mark = self.buffer.create_mark(end,
self.buffer.get_end_iter(), False)
self.textview.scroll_to_mark(mark, 0.05, True, 0.0, 1.0)
now, i have the same function in all four threads. Each updates a
different textview.
the threads run in a class threading.thread.
the code that calls them is like this.
S1 = Serial1(self.Input1Buffer, self.TTYS14View)
S1.start()
each thread has some initial code like this
class Serial1(threading.Thread):
def __init__(self, buffer, textview):
threading.Thread.__init__(self)
self.buffer = buffer
self.iter = self.buffer.get_end_iter()
self.textview = textview
my question is. from the main app, if i pass the textview and
buffer to each thread that needs one, can i, from the thread pass
those as objects to one function that will update the text view? if
so, do i need to make that function a global object ? or can i just
declare it at the beginning of the program ?
does this question make sense?
if you have read this far, i thank you for your time.
shawn
Yes, you can pass the buffer pointers around. I have done it many times.
No you do not need to make them global.
Updating any gui items from a thread other than the main gui thread is
asking for trouble. For any thread to safely access the textview buffer
you need to wrap it with calls to gtk to get clearance (sorry, don't
recall the actual function names atm) to modify them without causing
conflicts. Something that can hold up your thread waiting for the
update to sync with the gui.
A much safer way to go is to gather your info in the threads and then
pass that info back to the main gui thread to update the correct buffer.
A good example of this is using the dispatcher module we've come up with
that handles the inter-thread communication collision free. see
attached code. You will see in the example code that the buffer pointer
is passed to the method that appends the text to the buffer. It should
be easy to modify the example code to use different buffers for each
thread.
I have used global variables in our app which has several notebook tabs
each with their own textview and use the same append method. I used
global lists to store the buffer pointers and pass the index number to
the append module as there are several other things that use the index
number as well. Word of caution if you intend on using a list to store
the pointers use the list.append() to add them to an empty list, don't
initialize the list like:
buffer_list = [None, None] # it won't work
buffer_list = [] # works
buffer_list.append(buffer_pointer1)
buffer_list.append(buffer_pointer2)
code snipit:
def append(self, num, text, tagname = None):
Append text to a text buffer. Line numbering based on
the process window line count is automatically added.
BUT -- if multiple text buffers are going to be updated,
always update the process buffer LAST to guarantee the
line numbering is correct.
Optionally, text formatting can be applied as well
#dprint(Notebook: overwrite() -- num= + str(num))
#dprint(self.current_tab)
line_number = self.view_buffer[TAB_PROCESS].get_line_count()
iter = self.view_buffer[num].get_end_iter()
lntext = str(line_number).zfill(6) + ' '
if self.last_text[num].endswith('\n'):
self.view_buffer[num].insert_with_tags_by_name(iter, lntext,
'linenumber')
if tagname == None:
#self.view_buffer[num].insert(iter, text)
#dprint(Notebook: append(): attempting to set text with tagnames
+ str(self.current_tagnames))
self.view_buffer[num].insert_with_tags_by_name(iter, text,
*self.current_tagnames)
else:
self.view_buffer[num].insert_with_tags_by_name(iter, text, tagname)
if self.auto_scroll[num] and num == self.current_tab:
self.scroll_current_view()
self.last_text[num] = text

I've checked all the things that should be obvious problems: I'm calling: gobject.threads_init() gtk.gdk.threads_init() before gtk.main() is called There is no race condition or blocking call causing everything to get stuck. The thread's only interaction with the rest of the program is via the Queue.Queue object that keeps the requests to be processed. I've stepped through with pdb and it freezes in a completely innocuous place in the code (during a loop where I append to a list). The freeze occurs in slightly different places depending on what kind of debugging code I put in, changes to the order of things, etc...so it feels like it's some kind of corruption in the interpreter stack. Running the processor thread in a dummy app without the pygtk part never freezes up. Running the pygtk app with a non-threaded processor, which just sequentially runs the requests and waits till they complete, never freezes up. I'm at my wit's end here...I know threads are just asking for trouble, and usually I avoid them, but circumstances here basically require threading (all the request time is spent waiting on different kinds of IO). The setup was so simple, I figured I couldn't possibly run into trouble...yet here I am. So, anyone have any idea what could cause the entire python interpreter to freeze solid?

Hi Dave,
I will turn my question differently: in your answer your my_handler
accepts keywords. Then how do you pass them to your my_handler in the

the next dic key-entry pair. Maybe I'm wrong. Or is a tuple or a list
OK as an entry in such a dictionary ?

removed a few function parameters you'll see.
I think you should change the adj1.connect() to store the adj value and
print the degF value in something in your window, then use the commented
out method in the print_celcius to convert then print the temp.
That should give you a few more ideas :)

Thanks, Nathan French Yeah, it doesn't always work unless you make a mark at the end of the buffer. Set the property so that any text inserted will be to the left of the mark. Then scroll_to_mark.

Re: [pygtk] User defined interface

The application is supposed to show some data that is read from an XML file. Now what I need is to give the user the flexibility that she/he can set up how she/he wants the display widget to look like. My idea is to use a table widget as the base and that the user can put Labels, Pixmaps, and choose where in the table to display the data (and later also be able to edit data). So my question is: Given that the layout is defined in an XML file is it better to: 1. in some way (if possible) to use libglade to read a XML file that doesn't have a main window but only a Table widget as the base? As the layout will change depending on what data to display. 2. make ones own parser to read and generate the display GUI from the XML structure. I'm also thinking that later when I want to add edit capabilities I need to hook callbacks to the different edit widgets and that may be easier without libglade 3. or has somebody already made something like this that is available in as a library or similar? The program will be licensed as GPL or BSD if finished. Thanks in advanced for any hints. Preben Look at Gaspacho and Kiwi. It sounds like that may be able to do what you would like.

[pygtk] gtk.button stock images, color change possible?
In our app, I have put 3 buttons on the bottom of the window beside the
status bar. I have made bare buttons and use stock images for two. One
is a pause image, another is a play image and the third is a custom
clock image. (specialized terminal app, command queue features {pause,
run, timer})
Is it possible to change the foreground color of the image depending on
the state? I have tried using the gtk.Widget.modify_fg(), but it does
not seem to work. The reason I am trying to change it is because it is
difficult to see whether it is active or not since they are small
buttons. I realize some of this can be changed by changing my desktop
theme. I would like to stay with stock images if possible it suits
the purpose. Do I have to use custom images for this to work?
snipit:
self.pause_btn.modify_fg(gtk.STATE_INSENSITIVE,
gtk.gdk.color_parse(#962A1C)) # dark red
self.pause_btn.modify_fg(gtk.STATE_NORMAL,
gtk.gdk.color_parse(#DA311B)) # med red
self.pause_btn.modify_fg(gtk.STATE_PRELIGHT,
gtk.gdk.color_parse(#F65540))# light red
self.play_btn.modify_fg(gtk.STATE_INSENSITIVE,
gtk.gdk.color_parse(#3C6E38)) # dark green
self.play_btn.modify_fg(gtk.STATE_NORMAL,
gtk.gdk.color_parse(#4EBA44)) # med green
self.play_btn.modify_fg(gtk.STATE_PRELIGHT,
gtk.gdk.color_parse(#58F64A)) # light green
I just realized something that may be affecting my results. I have an
instance of the app running some package upgrades from before this
change. Would that cause python to not create new .pyc files for the
modified files since there is another instance loaded and running?
I'm tired, and heading off to bed. In the morning ill have an updated
system with gtk+-2.8.18 to test out.

[pygtk] treview segfaults due to sorting
Our app has several treeviews. One of those has several models that are switched out, 3 are flat lists, 1 currently has one expander and child nodes. If the expander is opened, when switching to any of the other models, it gets an instant segfault from the model.clear(). If I comment out the clear() it segfaults still, just a little different. The only thing I've been able to do so far to prevent the segfault is to force a re-sort by clicking on one of the other column headers. Normally the sort is on the first column (0). All models share the same treestore model. The checkbox is hidden for all but one view. def PackageModel(): Common model for a package Treestore store = gtk.TreeStore( gobject.TYPE_STRING,# 0: package name gobject.TYPE_BOOLEAN, # 1: checkbox value in upgrade view gobject.TYPE_PYOBJECT, # 2: package object gtk.gdk.Pixbuf, # 3: room for various icons gobject.TYPE_BOOLEAN, # 4: true if package is in 'world' file gobject.TYPE_STRING,# 5: foreground text colour gobject.TYPE_STRING,# 6: size gobject.TYPE_STRING,# 7: installed version gobject.TYPE_STRING,# 8: portage recommended version gobject.TYPE_STRING,# 9: description ) store.set_sort_func(6, size_sort_func) store.set_sort_func(8, latest_sort_func) store.set_sort_func(7, installed_sort_func) return store I do not know if this is a gtk bug yet or something we are doing wrong.

Knowing myself, I imagine I looked pretty hard for a better solution

Here is how we do it without a hack.
self.notebook.connect(switch-page, self.switch_page)
def switch_page(self, notebook, page, page_num):
callback function changes the current_page setting in the term
structure
dprint(TERMINAL: switch_page; page_num = %d %page_num)
self.term.current_tab = self.term.visible_tablist[page_num]
if self.term.auto_scroll[self.term.current_tab]:
self.scroll_current_view()
return
You should be able to decipher the above code snipit without more
explanation. We have a number of tabs that may or may not be visible.
The pygtk reference page:
http://www.pygtk.org/pygtk2reference/class-gtknotebook.html
and the pertinent info:
The switch-page gtk.Notebook Signal
def callback(notebook, page, page_num, user_param1, ...)
notebook :
the notebook that received the signal
page :
the new current page
page_num :
the index of the new current page
user_param1Â :
the first user parameter (if any) specified with the connect() method
... :
additional user parameters (if any)
The switch-page signal is emitted when the notebook page is changed.
Note the page parameter is a GPointer and not usable within PyGTK. Use
the page_num parameter to retrieve the new current page using the
get_nth_page() method.

[pygtk] Re: Using adjustments to 'remember' treeview's position
I'm not sure that I totally grok what you are trying to do, so forgive me if this is not helpful. But, you can use the adjustment's values to remember its position (or at least get it close). For an adjustment, adj, you have the following: adj.value (current value), adj.lower (lowest value), adj.higher (highest value), and adj.page_size (how the adjustment breaks up values in pages). So, if you want to remember where you are, and the overall size of your view in that context does not change, you can just save adj.value, and then call adj.set_value(v) to restore the position. Or, you can use all the available values to determine a relative value, if the view is shrinking and growing a lot. ___ 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] Threading issues...
On Mon, 2005-29-08 at 13:18 +1000, Simon Gerber wrote: Greetings all, I'm, err, having threading problems. I've googled through this list, and indeed as much of the Internet as I can reach, looking for answers and workaround to no avail. I am still just learning, really, and have a feeling I've bitten off more than I can chew. The situation is this: I am trying to create a gnome applet that checks mail accounts, displaying the usual stuff. The files involved are: gnoptray.py - script that launches the applet cApplet.py - Module containing the applet class cAccounts.py - Module containing an 'Account' class. It is built using (not extending) imaplib and poplib. It stores an internal dictionary of message headers, can update itself, fetch and delete messages. guiAccount.py - GTK extensions to the cAccounts.Account class. Creates a GUI that sets account attributes, such as username, password, etc... The problem I'm having is with checking mail. I started by creating a timeout that would call the update() method of a guiAccount object. Obviously, this freezes the entire UI. I don't really want to update the GUI while checking... I just want my menus and such to appear while it's churning away in the background. So I tried threads... Throwing in gtk.threads_init(), wrapping gtk.main() in gtk.threads_enter() and gtk.threads_leave() - doing the same with my time-out callback. e.g ... if interval != 0: self.timeout_ids[name] = (gobject.timeout_add(interval, self.check_mail, name)) def check_mail(self, name): thread1 = threading.Thread(target=self.accounts[name].update()) thread1.start() return 1 But nothing really worked. The UI still froze until checking was complete. Is it worth pursuing this path? I have tried generators, but they did not work as expected. I am now considering writing a daemon application to do the actual mail checking - and just feed it into the GUI through an input_add(). Either that or toss out my cAccounts.py module and build a gtk version of imap/poplib using input_add. Any help would be much appreciated. Cheers, To handle threads and inter thread communication You have a couple options. There is a dispatcher.py project out there that can handle all sorts of inter process communications, etc.. We have come up with a small simple way of handling threads and gtk callbacks. I've attached a small dispatcher.py script and an example script that shows how to use it. This dispatcher code has fixed a lot of bugs and intermittent problems with our project. It does a great job of separating code and callbacks when dealing with threads. It allows you to run all gtk/gui calls from one thread while other threads can trigger callbacks and pass data into or out of a thread. The dispatcher code can reside in any thread and receive calls from any other thread. For our project the dispatcher instances all belong to the main gtk thread and receive signals from feeder threads. It is engineered generic enough to be able to pass any python data between threads. -- Brian [EMAIL PROTECTED] #! /usr/bin/env python # Fredrik Arnerup [EMAIL PROTECTED], 2004-12-19 # Brian Dolbec[EMAIL PROTECTED],2005-3-30 import gobject, os, Queue from select import select class Dispatcher: Send signals from a thread to another thread through a pipe in a thread-safe manner def __init__(self, callback, args=None): self.callback = callback self.callback_args = args self.continue_io_watch = True self.queue = Queue.Queue(0) # thread safe queue self.pipe_r, self.pipe_w = os.pipe() gobject.io_add_watch(self.pipe_r, gobject.IO_IN, self.on_data) def __call__(self, *args): Emit signal from thread self.queue.put(args) # write to pipe afterwards os.write(self.pipe_w, X) def on_data(self, source, cb_condition): if select([self.pipe_r],[],[], 0)[0] and os.read(self.pipe_r,1): if self.callback_args is not None: self.callback(self.callback_args, *self.queue.get()) else: self.callback(*self.queue.get()) return self.continue_io_watch #! /usr/bin/env python # Fredrik Arnerup [EMAIL PROTECTED], 2004-12-19 # Brian Dolbec[EMAIL PROTECTED],2005-3-30 from dispatcher import Dispatcher # # dispatcher # example code: # # # class Thread(threading.Thread): def __init__(self, dispatcher, thread_num, length): threading.Thread.__init__(self) self.setDaemon(1) # quit even if this thread is still running self.dispatcher = dispatcher self.thread_num = thread_num self.sleep_length = length def run(self): done = False print(thread_num = %s; process id = %d %(self.thread_num,os.getpid())) pid_func

[pygtk] Re: Themes and Stand Alone GTK
Two simple questions:
1) There's a way to set the theme that an app will use, without
setting it globally or for the user? Like, just that app will use a
different theme...
2) Using Python or py2exe to generate a standalone executable requires
the installation of the gtk runtime for win32, there's a way to pack
the runtime in some way that doesn't require installing the whole
package? Like, a private gtk installation on the apps dir.
I can answer #1 for you. You can have an application specific stylesheet,
which you can read in intialization with gtk.rc_parse(filename), or you can
use an inline style sheet, embedding in the code, which you can parse with
gtk.rc_parse_string(string). An inline style looks something like this:
my_style_string =
style white_background {
fg[NORMAL] = #00
bg[NORMAL] = #FF
text[NORMAL] = #00
base[NORMAL] = #FF
}
widget *.white_bgd style white_background
gtk.rc_parse_string(my_style_string)
I think you got a good answer to #2 already...

[pygtk] Re: Popup menus on Notebook tabs
I'm trying to produce a menu effect in PyGTK similar to the Mozilla tab
bar,
where a right-click on the tab produces a popup menu to perform various
actions on the tabs (and/or contents thereof). I can get most of the way
(sort of) with a button-press-event handler, but there's a couple of things
I can't manage to effect: (a) A right-click on the untabbed portion of the
tab list still gives the menu, and (b) I can't work out which tab was
clicked on.
For (a), you can call notebook.popup_disable() when you create the notebook,
as long as you don't need the default popup menu that the notebook creates.
For an easy way to create popup menus, and figuring out which tab a click
comes from, put your tab labels into event boxes:
tab_label_box = gtk.EventBox()
tab_label = gtk.Label(Some label here)
tab_label_box.add(tab_label)
tab_label_box.connect('event', on_tab_click)
notebook.append_page(your_page_widget, tab_label_box)

What really got me confused was trying to update our program to use the new toolbar API, (Only one tooltip is dynamic.). Where I got into trouble was that a gtk.Button uses gtk.Tooltips.set_tip() while the new inherited method is .set_tooltip(). The 2 names are so similar that my brain didn't notice the difference. The other confuser was that both use gtk.Tooltips, but differently. The new toolbar seems to only use the instance for the enable/disable(), the old API seemed to store the tooltip string in the gtk.Tooltips instance. -- Brian [EMAIL PROTECTED] ___ 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/
[pygtk] Problems getting color values
Does anybody know how to get the rgb values from a gtk.gdk.GC?
Attempting to access the values returns garbage, as evidenced by this
example:

Type help, copyright, credits or license for more information.
import pygtk
pygtk.require('2.0')
import gtk
widget = gtk.Window()
widget.show()
style = widget.get_style()
gc = style.fg_gc[gtk.STATE_NORMAL]
gc.foreground
GdkColor at 0x10327ce0
gc.foreground.red
4107
gc.foreground.green
30416
gc.foreground.blue
0
colormap = widget.get_colormap()
red = colormap.alloc_color(0x, 0x00, 0x00)
red.red
65535
red.green
0
red.blue
0
gc.foreground = red
gc.foreground.red
4107
gc.foreground.green

The color in the gc draws correctly to the screen. I need the rgb values to
match gtk colors with rendering done by other code.

The expected behaviour is that when one clicks on the button, the

up the TreeStore, then show up the TreeView in the same position.
When you press the button for the first time, it works magically. But
when you try it after that, it freezes the application. I think I used
threads_enter() and threads_leave() according to the golden rules so I
don't really get what's wrong.

This code does not always work as expected. This is due to the
new_window_state and changed_mask possibly having more than one flag
attached. The event.new_window_state and event.changed_mask are
enumerated data types.
Here is an example of the event.new_window_state passed to the callback
function: (actual debug print of event.new_window_state)
flags GDK_WINDOW_STATE_ICONIFIED | GDK_WINDOW_STATE_MAXIMIZED of type
GdkWindowState
So far I have not found out how to properly look for a specific flag
when there are more than one. I have found this doc
http://www.python.org/workshops/1994-11/BuiltInClasses/BuiltInClasses_5.html
which describes how to integrate CType structures into python. It is seems too
terse for my understanding though.
I have got some code working (so far) using the change_mask which so far
is only passing one flag, but in the docs it states that it too can have
combinations of flags.
[quote]
changed_mask Read/Write The mask specifying what flags have changed - a
combination of:...[snip]
[/quote]
working code:
def new_window_state(self, widget, event):
set the minimized variable to change the title to the same as the
statusbar text
dprint(event.new_window_state) # debug print statements
dprint(event.changed_mask)
if event.changed_mask == gtk.gdk.WINDOW_STATE_ICONIFIED:
if not self.minimized:
dprint(TERMINAL: new_window_state; event = minimized)
self.minimized = True
self.window.set_title(self.status_text)
else: # self.minimized:
dprint(TERMINAL: new_window_state; event = unminimized)
self.minimized = False
self.window.set_title(self.title)
return False
A potential problem with this code is if the self.minimized variable
gets out of sync with the actual window state.
Anyone know how to do correctly?

Hmm, that is right. You may have to change the '==' tests to a
bitwise 'and' comparison:
(...)
if state gdk.WINDOW_STATE_ICONIFIED:
window.set_title('Iconified')
(...)
If you just want to have a flag to know that it is iconified you can
do something like:
class MyWindow(GtkWindow):
def __init__(self):
self.minimized = False
...
def new_window_state(self, widget, event):
state = event.new_window_state
if state gdk.WINDOW_STATE_ICONIFIED:
self.minimized = True
else
self.minimized = False
I think that what you want to do is simple, so do not complicate it :)
[Eric Jardim]
That's better. I knew there had to be an easy way. I just was not
finding it. In fact I googled the hell out of it but could not find
anything that listed comparison operators for it.

My intention is from the thread to run() the dialog and wait for the user to give the password and then use it. run() would normally do this, but it freezes with threads. I saw a workaround in FAQ 10.17 (about dialog.run running in the mainloop), but that won't block in a mainloop so it doesn't suit me. does someone has an idea ? You are running the dialog from a thread which is not good. You should run all gui stuff from the main thread, even if they are controlled by other threads. Here is an example of thread safe communication and control that can easily be changed to do what you were trying to do in your core.py. The dispatcher function in this example can pass arbitrary data between threads as long as each party knows what to expect.

Any ideas on how to programmatically determine libglade version? Or any other workarounds? Stephen. Here is how I did it so far on a gentoo system. Your method for checking the installed version will be different for a different distribution. ver_match() pads the version strings to three digits per so 2.4.1 would become 002.004.001-r000. -r000 being the install ebuild revision number. Then checks for a match in the ranges specified. portagelib is our programs interface to the imported portage modules (gentoo's package management system). I will most likely need to modify the code to choose which version to use if both ranges are installed. In gentoo I recommended that libglade-2.4.1 be masked due to bugs and incompatibility with existing apps. I also recommended it be slotted differently than current libglade-2 versions (which could mean there may be up to 3 simultaneous libglade versions installed on the system). def check_glade(): determine the libglade version installed and return the correct glade file to use porthole_gladefile = porthole.glade # determine glade version versions = portagelib.get_installed(gnome-base/libglade) if versions: dprint(versions) old, new = ver_match(versions, [2.0.1,2.4.0-r99], [2.4.1,2.99.99]) if old: porthole_gladefile = porthole.glade elif new: porthole_gladefile = porthole-new.glade else: dprint(MAINWINDOW: No version list returned for libglade) return None dprint(MAINWINDOW: __init__(); glade file = %s %porthole_gladefile) return porthole_gladefile def ver_match(versions, range1, range2 = None): looks for a version match in range1 and optionaly in range2 if not versions: return None plist = pad_ver(get_versions_only(versions)) r1 = pad_ver(range1) if range2: r2 = pad_ver(range2) if not plist: dprint(VERSION_SORT: ver_match(); plist[] creation error) return False, False match1 = False match2 = False for x in plist: if (x = r1[0] and x = r1[1]): dprint(VERSION_SORT: ver_match(); match1 %s, %s:%s %(x,r1[0],r1[1])) match1 = True if range2 and (x = r2[0] and x = r2[1]): dprint(VERSION_SORT: ver_match(); match2 %s, %s:%s %(x,r2[0],r2[1])) match2 = True return match1, match2 class MainWindow: Main Window class to setup and manage main window interface. def __init__(self, preferences = None, config = None): preferences.use_gladefile = check_glade() # setup prefs self.prefs = preferences self.config = config # setup glade self.gladefile = self.prefs.DATA_PATH + self.prefs.use_gladefile self.wtree = gtk.glade.XML(self.gladefile, main_window, self.prefs.APP) [snip] -- Brian [EMAIL PROTECTED] ___ 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] feature request: binding for gtk_propagate_event?
With gtk1/gnome1, binding the signals seems to happen when a widget-tree is added to the AppletWidget container. So, if you add Buttons to a GtkHBox, and then add that box to the AppletWidget, the button-events are processed by the panel. If you first add the GtkHBox, and then add the buttons to the GtkHBox, then those buttons receive events button2 and button3. Some explicit mechanism for gnome2 to bind the signals would be better. Hmm, interesting that you mention this layout, because I just tried the same hack with a different applet (one that puts a GtkButton and a GtkProgressBar into a VBox, then the VBox in the applet), and in this case the hack does not help. I suspect the signals are being sent to the VBox, which ignores them. So the menu is accessible by button3 from within the progress bar, but not from the button (just as it without the parent.emit hack). Am I right in thinking that events are propagated backwards (from window to parent window and so on up to the root window) until somebody claims them, but that gtk signals are not? That might be why the gnome-applets authors used gtk_propagate_event instead of re-emitting signals: the immediate parent might not be the appropriate recipient. More ideas are most welcome.. thanks, -Brian ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
Re: [pygtk] feature request: binding for gtk_propagate_event?
Have you tried container.emit() instead of propagate_event? I think
there's a good chance of it working.
Thanks, that seems to help. The right-clicks now drop through to the
underlying panel and manage to bring up the menu (and make it go away again).
I haven't figured out how to send button2 through (to invoke the drag-applet
stuff), but I figure I'll probably have to look more deeply into gnome-panel
to figure out what events it wants to receive that the GtkButton is
consuming.
I still wish I knew why this stopped working in Gnome2. I'm pretty sure it
was easier to use back in Gnome1.
For reference, here's the pair of helper functions I ended up using. Just use
MyButton() whereever you'd use gtk.Button(), and mouse2/3 press/release
events will be sent up to the Button's container:
def button_hack_helper(widget, event, updown):
if event.button != 1:
if updown == press:
widget.parent.emit(button_press_event, event)
else:
widget.parent.emit(button_release_event, event)
return gtk.TRUE
return gtk.FALSE
def MyButton():
b = gtk.Button()
b.connect('button_press_event', button_hack_helper, press)
b.connect('button_release_event', button_hack_helper, release)
return b
thanks for the help,

[pygtk] feature request: binding for gtk_propagate_event?
Howdy all.. I've been trying to rewrite my python/gnome1 -based applets in python/gnome2 (somewhat forced into it because of the recent debian/unstable gnome2 switch). One of the more significant changes in gtk2/gnome2 that shows up in panel applets is that right-clicks on top of GtkButtons no longer result in the applet's menu appearing. I don't know if this is because GtkButtons consume the button2 and button3 events instead of passing them up to their containers (they do, but from what I can tell they did in gtk1.2 as well) or because the new bonobo-based libpanel-applet system does something different than the old applet-widget scheme (it does, but I don't know if it is not implementing an old workaround or if something else changed). The net result is that, in the applets I write that contain buttons, it is difficult to get to the applet's context menu (to configure or remove the applet). If the applet is all button, it is impossible. Several of standard Gnome applets (in gnome-applets-2.0.3), drivemount and mini-commander in particular, have a hack to work around this. The hack adds a signal handler to the GtkButton which catches button2/button3 and uses gtk_propagate_event() to send the event off to the applet as a whole, which responds by putting up the context menu. button1 events are ignored/refused; the signal handler returns FALSE to let the event go to the GtkButton as usual. In lieu of seeing GtkButtons changed to let button2/button3 events get passed along to their containers, I wanted to implement this same hack in my python applets. But gtk_propagate_event() is missing from the python binding, as it is listed in an %ignore clause in the gtk.override file. Any idea why there is no binding for this function? Or how hard it would be to add one? If there's a better workaround for this problem I'd love to hear it, but I suspect a real fix would involve changes to gtk that aren't going to happen any time soon. thanks, -Brian ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
Re: [pygtk] Building on cygwin
Then [EMAIL PROTECTED] spoke up and said: First of all, are you talking about porting pygtk on cygwin using XFree (http://cygwin.com/xfree/) or the win32 port of gtk+ (as available from http://www.gimp.org/win32/) ? If you plan to use XFree, things should be xfree. I'm a unix sysadmin and would normally run linux or freebsd on my laptop, but it turns out I also need access to Windows software. My solution is to use the cygwin package with the cygwin port of xfree. It works extremely well, and building packages mostly just works. P.S. : what do you mean by the binary package is not cygwin friendly. You use python as provided by the cygwin distribution ? If it's the case, you must use XFree and port gtk+ and pygtk accordingly. Exactly. Sorry, I should have specifically mentioned xfree. In any event, it configures/builds just fine, except that when I try to use it, I discover that none of the widgets exist. pretty straightforward using the configure script. You might have to fight with dlltool/dllwrap to generate the _gtk.pyd though. If you want to use What's a .pyd? Also, there doesn't seem to be a Makefile rule for the creation of _gtk.py*.

For some reason, with the windows version of python, they sometimes rename the dll extension modules to the extension .pyd (they are still dlls). The pygtk build should build and install a shared library called _gtkmodule.dll. Does htis build okay on cygwin? Hrm. It seems to only be building .a files, not .dll (or .pyd, or anything else). It is possible that the problem you are seeing is that the GTK.py file overwrote the gtk.py file when unpacking the tarball. This problem has been fixed on the development branch, but remains broken on the stable branch (renaming the module would break compatibility). This is definitely what happened!
