Re: [pygtk] delete selection
Sorry for such a late response, but I just had a chance to come back to the pygtk stuff. Thank you for your help. I tried using the following code and it worked. However, it is meant only delete one row at a time right? (since get_slected() does not work in SELECTION_MULTIPLE mode) If I would like to delete multiple rows that are selected, do you have any suggestions? Again, using selection.selected_foreach produced errors. > #Here is the function attached to the delete button: > > def RemoveWatchVariables(button): > # delete each variable > def DeleteVar(model,path,iter,data=None): > model.remove(iter) > # get selection and iterate through > selection = watchvars_view.get_selection() > selection.selected_foreach(DeleteVar) On Tue, 2003-08-05 at 12:42, Grzegorz Adam Hankiewicz wrote: > On 2003-08-05, Yang Zheng <[EMAIL PROTECTED]> wrote: > > Can I not delete iterator like this? > > Hmmm... can't say what you do wrong, but here's my deletion code, > maybe it helps you: > >selection = self.list_view.get_selection() >model, iter, = selection.get_selected() >if iter: > path = model.get_path(iter) > model.remove(iter) > selection.select_path(path) > if not selection.path_is_selected(path): > row = path[0]-1 > if row >= 0: > selection.select_path((row,)) ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

However, GTK+ developers just told me, that one of the scans is for sure a "validation scan" - and there's no possilibity of turning it off. Such possibility will be added in 2.4. Thank you.

Well now you've gone beyond my knowledge of TreeView's, but I think there is hope. I remember an example where the children are not even added to a TreeStore until their parent row is expanded, so certainly no time could be wasted traversing them at start up time. Perhaps you can apply something similar to your TreeModel. The example is in the PyGtk FAQ: http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq13.030.htp Good luck, Gary Herron ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Use the more general TreeModel class. Well, I did. As I have been debugging, the TreeView requests only the values of the visible rows from the model - which is just fine - but just after TreeView.set_model my TreeView scans _all_ the rows of the model, 2 times. Well, I thought that this might be because of the columns auto-sizing option. I did set_size(gtk.TREE_VIEW_COLUMN_FIXED) on all columns. Still the same behaviour. How could I get around it?

[pygtk] PyGTK is just great.
Gentlemen, I am using PyGTK 2 on NetBSD and Win32 and I must say, that it is just great. Everything works fine, using glade I can develop GUI very fast, TreeViews are the best thing I have ever seen in a GUI library and the API makes a lot more sense, than wxWindows (I have used wx before). And, on Win32 platforms, the different look of GTK (when not using GTK-WIMP) might be even a feature (did you notice, that there's a tendency in Windows world to create applications, which don't look too standard?).

Note that subclassing *does* work fine in 0.6 -- Kiwi uses it all over
the place :-)

You can implement this by associating myVar with an instance and hooking
the __setattr__() method to do a spinbutton value update (using
set_value() or set_text(), depending on the content).
I do this in the Kiwi (http://www.async.com.br/projects/kiwi/) Proxy
class automatically, but it doesn't support PyGTK2 (yet).

Which means you want the reverse of what widget.connect() does.

Really? Do you have a reference for code that does this? I'm curious to
see what the semantics are.

See http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq03.007.htp The trick here is to realize where your callback can take a while to return, or where it is dynamically changing the window contents, and add a section like this in the body of your callback handler: while gtk.events_pending(): gtk.mainiteration(gtk.FALSE) This tells gtk to process any window events that have been left pending. If your handler has a long loop, for instance, inserting this snippet as part of the loop will avoid it hanging the window till the callback has finished.

The patch that I submitted on bugzilla was just a primitive hack to let everyone know about the problem since I couldn't find any bug already submitted about this. I like to keep an upto date copy of PyGtk compiled on my WinXP box. That was the quickest way to get it done without knowing too much about the inner workings of all the .override files. Alif.
