Re: [pygtk] Memory leak when using pangocairo for animation

I was Googling for this and found this mailing list post and then noticed that the date was only three days ago (thanks for the quick indexing Google) and thought I should chime in. Thanks, I was still waiting to hear if anyone was able to reproduce it. My code does it on two different Linux distros so far. I was hoping I'd someone would just say it's because you forgot to X, but unfortunately I'm beginning to think it's a bug. I have a custom cairo widget inheriting from a gtk.DrawingArea that displays some text and refreshes very frequently. Using cairo's built-in text rendering (i.e. show_text()) I do not see the memory leak but when I switched to using pangocairo then I saw the massive memory growth. Good to know the Cairo native rendering doesn't leak, I may have to work around it this way. Unfortunately, I don't think the built-in Cairo text rendering supports any sort of markup like Pango does; I am using that heavily in my app. If I'm right, it would be lots of tedious code to position things and set fonts and so forth by hand. :( -Kyle ___ 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] cell.set_property and colors - SOLVED

It turns out that if you set 'cell-background' you need to set it in *any* cell. You can set it to None and it will use the default (that may happen to be an alternating scheme). I still don't really udertand if the cell object I'm setting the property is a unique instance for the whole column (I think so) or one instance each cell. sandro ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
[pygtk] Cell renderer repository?
Hi, I'm in the need to write a cell render for what I believe a common thing: a text editor for log text that is not easy to edit in the standard CellRendererText. I'm wandering if there exist already such a renderer or a repository of cell renderer ready to use. A second one I need is Date/DateTimeRenderer. I guess I'm not the first one that need such a beast... sandro ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
[pygtk] limit width of gtk.ComboBox
From the PyGTK FAQ (http://faq.pygtk.org/index.py?req=all#12.2), it appears that there is not a way to limit the horizontal space the widget requests. I am aware of the set_ellipsize() method of gtk.Label ( http://www.pygtk.org/docs/pygtk/class-gtklabel.html#method-gtklabel--set-ellipsize), but is there a method that will accomplish the same thing for Combo Boxes? I have some really wide text entries that I wouldn't mind popping out at full width, but I would like for the combo box itself to have a fixed width and truncate the currently selected text. I suspect there might be a way to write a custom CellRenderer to pull off this effect, but I'm not sure how to use it with the ComboBox.

If you just wanted progress you could use a reporthook function passed to urlretrieve that would update the UI then while gtk.events_pending(): gtk.mainiteration(False) to update the UI. That should make your UI responsive to the user to and you just have to be careful that you don't call mainiteration, or mainloop, from multiple places. Keep in mind that my application is so old that I use 1.x so the programming model, or just names, might have changed in 2.x.

A second one I need is Date/DateTimeRenderer. I guess I'm not the first one that need such a beast... At one point, a long time ago, I did this by setting a custom data function for a cell with (C func) gtk_tree_view_column_set_cell_data_func. The custom data function would get the value from the tree model, format it as needed, and then set the text attribute of that cell's renderer. The renderer itself was a text renderer. Looking that the pygtk reference manual, this can be accomplished with gtk.TreeView.insert_column_with_data_func() HTH -- Mitko Haralanov == Computer programmers do it byte by byte. ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
