Re: [pygtk] ProgressBar widget click event
Il giorno lun, 06/11/2006 alle 19.00 -0500, Noah Schwartz ha scritto: I don't seem to be able to capture the click event for ProgressBar. I tried connecting the button-press-event to a function but, it wasn't getting called. Then I set it up to capture all events and still I wasn't capturing clicks. Maybe I am wrong, but the progressbar doesn't support clicking events. You can create a button (which is a container) and associate a progress bar as child. This way, when you press the progress bar, you really press the button, that emits the clicked signal. You can give no border to the button, making it invisible.

Re: [pygtk] Bug in TreeView.scroll_to_cell()

Try doing the scroll_to_cell in an idle_add callback. OK, it took me a while to understand (never used idle_add :) Thank you for your help. I tried: ... if (self.magaddpath != 0): print self.magaddpath selection = self[tv_mag_list].get_selection() gobject.idle_add(self._scroll_to_cell, self.magaddpath) selection.select_path(self.magaddpath) self.on_tv_mag_list_selected() self.magaddpath=0 def _scroll_to_cell(self, pos): self[tv_mag_list].scroll_to_cell(pos) This all is part of a class, hence self._scroll_to_cell inside idle_add() It works exactly as before, showing the row as last cell in the view It seems that it makes his best to show it, but also tries to show something else. I've also read something about page_clamp() or similar, but it seems it doesn't exist anymore for treeviews, only for adjustments. Any other ideas? -- Alessandro Pellizzari ___ 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] Combobox performance problems
Hi, I am writing a software that needs a lot of ComboBoxes. I am using python-gtk2 2.6.2 with gtk 2.6.7. I have an entry window with 4 comboboxes. I must update the liststore associated with those combos everytime I open the window, as the lists can be modified in other parts of the program. To achieve this, I call a function every time the window gets opened that does model.clear() model.insert_before(blah blah) It works well for the first 4-5 times I open the window, then it gets slooow. After 15-20 times, it takes about 5 seconds (on a Centrino 1400) to show up the list of options when I click the ComboBox. I think I will (temporarily) solve the problem destroying and recreating the model everytime the window gets opened, but I wish to know if this is a known bug or if there is a better way of doing this kind of things. Thanks. Bye. -- Alessandro Pellizzari ___ 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] intercept focus-out-event before other signals
Hi, in a program I am writing there are a treeview and a textview. Selecting a row in the tree allows you to modify the associated text. I need to intercept any action the user may do when the textview loses focus (tipically save the associated text), so I connected the focus-out-event signal. The problem is that the signal gets emitted AFTER any other signal. By exmaple, if I select a new row in the treeview, first I get the row-changed signal, and only after the focus-out-event. This way the contents of the textview gets lost (replaced by that of the new row) before I can save it. Is there a way to modify the focus-out priority, or to use another signal that gets emitted before anything else? Many Thanks.

[pygtk] TextView: signal when cursor changes position
Hi, I need to know when the cursor inside a TextView changes position. I tried to link to move_cursor signal, but if I move the cursor with a mouse-click, the signal doesn't get emitted. Is there a proper signal to link or must I catch both move_cursor and button_released?

[pygtk] Multithreading GUI + waiting for an Event
Hi,
I am writing a software and I would like to multithread it.
I've put the whole GUI into a class which inherits from
threading.Thread. This is the code:
class gui(threading.Thread):
def run(self):
self.gui = libglade.XML(gui.glade)
self.nameFuncMap = {}
for key in dir(self.__class__):
self.nameFuncMap[key] = getattr(self, key)
self.gui.signal_autoconnect(self.nameFuncMap)
gtk.threads_init()
gtk.main()
The problem is that I want to receive also events from the core part of
the program.
I know I can define a self._signal = threading.Event() into the
constructor or the run() method, but I don't know where to put the
self._signal.wait(), because gtk.main() monopolizes the thread.
Any idea?
Must I subdivide the GUI thread into 2 separate threads? And if so...
how? :)
Thanks! Bye.

[pygtk] Changing expand/shrink at runtime
Hi, I am writing a Python+Gtk2+Glade2 application. I placed a button that, when pressed, hides some widgets. But I created thos widgets with Y expand TRUE and now those containers (now empty) keep on expanding vertically. Is there a way to set Y expand to FALSE at runtime (and then back TRUE when re-show()-n?)
