[pygtk] Selection and?...
In some circumstancies I get to a situation as in the attached image, a row in a TreeView is selected but a cell in another row has a different background (pink in the image). I don't really know what state is that so that I don't know how to look for info... Which other stated do exist apart selected? sandro *:-) attachment: selection.png___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

You can do via TreeViewColumn.set_cell_data_func and calling

This approach has cleaned up my code somewhat, but there's one snag
I've hit. The object with the properties I'm showing in the table is a
subclass of GObject, and it has a use property that is displayed in
a CellRendererToggle in the table. It's easy enough to connect to the
activate signal and change the use property in the object, but
it's going to other way I'm having problems with, ie. updating what
the table displays when the use property changes in the object.
Is there a way to tell the CellRenderer to redraw, or recheck?
sure. Emitting a row-changed will trigger a redraw:
model.emit('row-changed', path, iter)

Hah! Okay then, now that it's morning, I can't believe that didn't occur to me :P While we're on the topic though, it strikes me as more sensible to simply put the objects themselves in a ListStore without manually extracting the information for the other columns (ie. so the ListStore just contains one column, which is displayed in different ways). Is there a way to tell each TreeViewColumn to, say, look at column zero, take the x.fit.param_A attribute, format it using 0x%03X and display it in a CellRendererText — and then so on for each attribute, each describing to a different view of the same column? Sure, you can use column's set_cell_data_function's method to sett cell's property values as you prefere. These functions will be called pretty frequently, each time a cell's area is redrawn, but it's not called for not visible cell's -as far as I understood-. That means it can be faster or slower that a pre-process in which you set all item's in advance in each column. I use this method in sqlkit and you can have a look here [1] to see several different cell_data_functions for different data types. sandro *:-) [1] http://hg.argolinux.org/py/sqlkit/file/tip/sqlkit/widgets/table/columns.py -- Sandro Dentella *:-) http://www.reteisi.org Soluzioni libere per le scuole http://sqlkit.argolinux.orgSQLkit home page - PyGTK/python/sqlalchemy ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
[pygtk] broken Reordable TreeView 2.22?
hi, I just realized that pygtk 2.22 has broken .set_reordable(). Given a TreeView with set_reordable() I can grab the row and move it around, but the selection underneath does not change and it not possible to drop it in a different position. I verified this behaviour on 2 XP boxes with gtk installed from the all-in-one installer. I attach a simple script that shows the problem: under XP + 2.22.1 I can't drop the lines in new positions. Is this a known issue? do other people verify this? sandro *:-) -- Sandro Dentella *:-) http://www.reteisi.org Soluzioni libere per le scuole http://sqlkit.argolinux.orgSQLkit home page - PyGTK/python/sqlalchemy ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

[pygtk] gtk.Builder inherited widgets
Hi,
in the attached example I have a very simple xml definition (a button in a
Window).
The Button is not really a gtk.Button it's defined with its own signal:
class Test(gtk.Button):
__gtype_name__ = 'Test'
__gsignals__ = {
'my-signal' : (gobject.SIGNAL_RUN_LAST,
gobject.TYPE_NONE,
()
),
}
def __init__(self):
self.emit('my-signal')
A second Test is derived from this one. The example fails when using the
second example and works correctly with the first one.
What am I doing wong?
It seems there's no way to make it see the signal defined in the derived
Test2 class, but I don't see anything special. Even Test inheritates from
other widgets (gtk.Button).
Any hints?
thanks
sandro

If I understand correctly, what makes the difference, is that you're emitting
the signal OUT of __init__. That works but does not explain why Test1 *can*
emit from within the __init__.
In the real example, the signal is really emitted within __init__, and that
have always worked in glade.

Have you followed some other docs? Should I be able to put the pythonplugin* stuff in a place visible for the whole system? 2. The name pythonplugin.py and pythonplugin.xml are hardcoded in glade (or better in it's python plugin)? I don't ned to change I just want to understand 3. [1] says: c) make sure your catalog name is the same as your python import library since glade_python_init() will use this name to import your widgets into the interpreter. I don't understand.Catalog name is pythonplugin.xml? 4. If you don't need glade (the application) as .xml files have been created already, do you need the plugin or you just need that at Builder.add_from_file() time the widgets are available to python? That's my impression... 5.

[pygtk] 'name' attribute for objects created by gtk.Builder
Hi,
in the process of migrating from glade to Builder I wrote the 2 attached test
files, where the main part is:
gld = gtk.glade.xml_new_from_buffer(__doc__,len(__doc__))
gld.get_widget('window1').connect('destroy', gtk.main_quit)
print Lable.name, gld.get_widget('label1').name
label1
bld = gtk.Builder()
bld.add_from_string(__doc__)
bld.get_object('window1').connect('destroy', gtk.main_quit)
print Lable.name, bld.get_object('label1').name
None
Where clearlu 'name' attribute is empty for the object created w/ Builder
and has the name I gave to the object in glade, for libglade.
I don't know it a 'name' object should exists, but which is the canonical
way to the get the name given in the glade interface?
Not that clearly get_object('label1') works correctly!
thanks in advance

[pygtk] CheckButton: toggled vs. clicked signal
Hi,
I just realized that a 'clicked' signal is emitted each time a value
is I toggled using .set_active(is_active) in a CheckButton.
I find it misleading and counter-intuitive since no one is clicking
anything. If that's the desired behaviour, what is the difference between
signal 'toggled' and 'clicked'?
The documentation states: The clicked signal is emitted when the mouse
button is pressed and released while the pointer is over the button.

[pygtk] set_interactive documentation
Hello everybody, A few years ago I wrote a patch to allow interactive usage of pygtk, by including a new function set_interactive. The code in this patch was included in pygtk versions 2.15.0 and later. I would like to add some documentation for this function, but I am wondering what the appropriate place for that is. The PyGTK reference manual at http://library.gnome.org/devel/pygtk/stable/ describes classes in pygtk, while set_interactive is a function. Section 1.1 in the pygtk tutorial is more relevant: http://www.pygtk.org/pygtk2tutorial/ch-Introduction.html#sec-ExploringPygtk but the tutorial is based on pygtk version 2.4. It seeme to me that later in the tutorial there are some additions of later widgets. What would be the right place to add this documentation? I can't say and I can't really understand what the function does. Interactive PyGTK isn't what you can to via ipython -gthread? I use it a lot while debugging. sandro *:-) -- Sandro Dentella *:-) http://sqlkit.argolinux.orgSQLkit home page - PyGTK/python/sqlalchemy ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

it you want to write data to a widget, you can also use set_data():

[pygtk] How to destroy Window hierarchy and corner cases

If in the meanwhile I destroy() the toplevel window I notice that under Linux I get the following message: /home/misc/src/hg/py/sqlkit/sqlkit/layout/layout.py:661: GtkWarning: gtk_label_set_text: assertion `GTK_IS_LABEL (label)' failed msg_id = sb.push(idx, txt) /home/misc/src/hg/py/sqlkit/sqlkit/layout/layout.py:669: GtkWarning: gtk_label_set_text: assertion `GTK_IS_LABEL (label)' failed sb.remove(idx, msg_id) Under Windows sometimes it just crashed the application. The problem is that when I receive a delete-event from a window, I destroy() it but the children are not really destroyed, e.g., with ipython you can still browse all its methods. The difference is that get_toplevel() will return the widget itself rather than the toplevel. Which is the correct/suggested way to destroy all elements of a hierarcy of widgets upon delete-event?

(I might be wrong, but) I think that destroy() is not exactly what you think. I mean: for instance, w=gtk.Window() w.destroy() w.get_position() works perfectly and returns (0,0). mmh that's something I wouldn't have expected in fact. I think I'm really confused about destroy/delete freeing memory in this cases. Destroying a widget simply means deleting it from any widget gerarchy: for instance, if your widget is in a container, the container will forget about it; if your widget is a toplevel, it will disappear from the toplevels list. Then, if(f) the reference count for the object goes to 0, the object will be presumably really destroyed (its memory freed), but if you (through pure python, not pygtk) keep some reference to it, it will stay there: that's why the above w.destroy has no effect at all. When you destroy a toplevel, its children are destroyed only in the sense that they may become unreferenced, and then disappear. That said, I don't understand the error you get, neither why you'll experience crashes in Windows, and there _may_ be some (py)gtk bug showing; however, if I understood correctly what you're assuming, I hope I explained correctly why it's not a correct assumption. yes, that make sense at least! sandro *:-) -- Sandro Dentella *:-) http://sqlkit.argolinux.orgSQLkit home page - PyGTK/python/sqlalchemy ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

Has anyone tried to do anything like this? sqlkit uses completion in a dynamic mode and uses gtk.EntryCompletion.

The treeview has only one column, that holds the instance returned by sqlalchemy query. Each column has a cell_data_function that populates the cell renderers. Each column is specialized to handle a type of data according to specification desumed by information gathered from the __mapper__ of the result.

Re: [pygtk] how to associate a button press event on gtk.CellRenderer cell
Well the first reference seems to be of no use . I have a sneeky feeling second would have been of use :( Some algorithmic help would be of great use as i do not understand the gtk architecture very well . I am only beginning to learn pygtk. well... if you think so, go ahead and read the second reference... But I think you don't necessarily need that to make a cell renderer to be sensitive to a 'button-press-event'. You could use the signal of the TreeView, get the cell where the pointer is and do whatever you want, or you could just use the signal of the editable, depending on what you need. sandro ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

label = gtk.Label(title)
box = gtk.EventBox()
box.add(label)
column.set_widget(box)
box.connect('button-press-event', self.box_clicked_cb)
#column.connect('clicked', self.clicked_cb)
but box_clicked_cb is never called. Why that?
Any Hints?

So whenever an invalid text is entered in the entry box,the text color

I haven't tested this, but the method 'modify_text' should do what you
need. For example, to set the text to red, use:
entry.modify_text(gtk.gdk.color_parse('red'))
and to set it back to the default black:
entry.modify_text(None)
Well, that's what I get for not even checking the documentation before
posting. I forgot the first argument to 'modify_text' should be a state
value. The relevant states here are:
- gtk.STATE_NORMAL for unselected text
- gtk.STATE_SELECTED for selected text when the entry is focused
- gtk.STATE_ACTIVE for selected text when a different widget is focused
In case you need to change the background too, i tryed to use modify_bg with
no luck while modify_base just works. I have not understood which is the
difference between one and the other, not I could find an explanation
of the difference between modify_bg and modify_text. The second works to
modify the text of an entry, the first does not.
Any one can explain or pint to documentaion on the difference between
base/bg and text/fg?
In the kiwi package there is an interesting validation field that uses also
images as background. I wanted to do the same but didn't manage missing a
simpler example...

A MenuItem is a Container so you can add anything to it. In your case
create an empty MenuItem and add an HBox containing an Image and a Label.
Today pygtk FAQ is back (yesterday was not reachable) and I saw the solution
there. What I didn't imaginis that you can instantiate an ImageMenuItem as:
item = gtk.ImageMenuItem('Foo')
even thought official docs say:

unreachable) and the hint there shows that you can write:
item = gtk.ImageMenuItem('Foo')
even thought official docs say:
gtk.ImageMenuItem(stock_id=None, accel_group=None)
This works correctly

[pygtk] Simple question on reusing stock item
Hi, i'd like to use stock item in menu entries with modified labels to better suit context. * MenuItem doesn't allow to use images (reasonable) * ImageMenuItem doesn't appearently allow to change label (really???) I think I could go with IconFactory but it seems to me it's more complex than what is should be and I wandered if there is a simple way I was not able to work out.

Re: [pygtk] TreeView/cell/signals - SOLVED
If I understand your question I don't think that you can prevent the Entry that is used as the CellEditable for the CellRendererText from closing when activated. You can only prevent the edits from being applied which is the default. thanks for your answer that awoke my brain... Really you *can* stop the process, what you cannot do is stopping from withing 'edited' callback. You must be in 'remove-widget' callback. I ended up using some variables to define the validation-state during 'edited' callback, I can also start completion with EntryCompletion. It wouldn't normally even popup as the widget is deemed to be removed, but I intercept it with 'remove_widget_cb' that returns True to stop the process. It's up to you to prevent opening several different cell editable at that point... sandro *:-) -- Sandro Dentella *:-) http://sqlkit.argolinux.orgSQLkit home page - PyGTK/python/sqlalchemy ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

They are the same.
ok, I guess some hystorical reason...
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.
This sentenced induced me to think that stop_emission could be used always
while return True only by those signals that support it.
On the contrary in the following example I try to stop emission of
key-press-event from within the 'edited' callback back to the treeview
callback and it seems not to work.
I connected with Tab from the treeview a callback that shiftws the cell to
be edited, but I'd like to stop it under some conditions from within
editabel callback. it's enought to return True (Line 59) and it works
but it does not work instead the line:
self.treeview.emit_stop_by_name('key-press-event')
Did I mis-interpret the signal?

Would OptionMenu (that was deprecated in favor to ComboBox) give me the opportunity to set tootlip or I would meet the same problem?

[pygtk] Adding Validation in TreeView: how to use 'edited' cb and stop any other processing?
Hi, I'm trying to add validation in a TreeView. Connecting to cell's 'edited' signal I can trigger validation on a cell input and if the field is not valid I reset it to previous value. That's not ideal, since the invalid value must be completely reentered while I'd like to leave it there. really It's pretty easy to do exacly what I want trapping a Tab on the editable, but that's junst *one* way to travel throught data (albeith very common). What I was not able to do is to prevent from moving from that cell, from within the 'edited' callback.

[pygtk] [Announce] sqlkit - 0.8.5
I'm pleased to announce rel 0.8.5 of sqlkit, that adds many improvements to sqlkit. In this release localization has been added. I'd be very pleased if someone would like to contribute localization file for any language (but italian). Changes in this release: sqlkit 0.8.5 - 16.1.09 * localization: added localization for numbers and dates added localization for messages -- now waiting for translations ;-) -- * table: - added a smart way to automatically set dimentions of the table based on info retrieved from the database (thanks to Pietro Battiston) - complete rewrite of the column setup function - added a basic multiline cellRenderer - grately improved the navigation with Tab that now correctly triggers validation/completion * fields: many improvements in clean_value/validation * mask: - added handling of comments - fixed integer/float miniwiget (0 was rendered as '') - text now uses gtk.WRAP_WORD - fixed current_idx was a class attribute not an instance attr * layout: added check and hints on errors for Panes widgets * django_syntax: fix in typo * filters: fixed handlung of boolena NULL check in related tables * signals: - record_selected - record-selected to follow gtk standard - added records-displayed * widgets/layout: added label_map support * sqlwidget: rationalized menu entries The package --- SQLkit PyGtk package provides Mask and Table widgets to edit database data. It's meant as a base for database desktop applications. The application --- It also provides 'sqledit' a PyGTK application based on sqlkit that can be used from command line to browse and edit data. The package has 2 very rich demo suites for sql widgets (the main one in sqlkit/demo/sql/demo.py) and for layout creation Main features of sqlkit: * editor of databases in 2 modes: table mask * based on sqlalchemy: can cope with many different databases * very powerfull filtering capabilities: - each field can be used to filter records - filter may span relationship - date filtering possible also on relative basis (good for saved queries) * completion on all text field and foreign keys * very easy way to draw a layout for mask views * completely effortless editing of relationships * very easy way to set defaults * possibility to display totals of numeric fields * any possible sql constraint can be attached to a Mask or a Table. It can be expressed a s a normal sqlalchemy query or with django-like syntax * sqledit: python script to edit db Sqlkit is based on: --- * python (= 2.4) * PyGtk * Sqlalchemy (= 0.5) * glade * dateutils Dowload more: --- * http://docs.argolinux.org/sqlkit/sqlkit/download.html * hg clone http://hg.argolinux.org/py/sqlkit * google group: http://groups.google.it/group/sqlkit/ * License: GNU GPL ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

3. How is it different from returning True?
I tested it with::

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.
