Re: XML and treeviews
Why don't create a GtkCellRenderer derived object with the properties you need? At creation time you can get the 0:0 (the open tag row) GtkCellRenderer as argument then you can hide it when 0:0 collapse using a GObject signal. 2008/7/25 Gabriele Greco [EMAIL PROTECTED]: Couldn't you just add another row in the TreeStore for the closing tag? If root is 0 and node is 0:0, then inserting a row after node with parent root would be 0:1. The problem doing it in this way is that I've to attach an handler to every collapse/expand event and I've to show/hide a line for each of those events, I can do it but I thought there was a cleaner solution like an attribute of the CellRenderer to change the indent level of a given column item. -- Ing.

Issue with vim and GtkFileChooser
Hello, I'm trying to debug an issue with the GTK2 version of vim which has bothered me for a long time. After the first invocation of GtkFileChooser in vim, GTK's list of recently used files (~/.recently-used.xbel) gets written on events such as every single keypress, mouseclick or the mouse entering/leaving the window. This bug occurs with vim (at least) 7.0 and 7.1 built against GTK 2.10 (at least) on Linux. I assume that this is a bug in GTK, from what I can see it uses GtkFileChooser as in the reference manual and does not use GTK's recently used files list functionality directly. However I saw that the recently used files functionality was added to the GtkFileChooser in GTK 2.11. I've spoken with Bram Moolenaar about this and he also believes this to be a bug in GTK. This is as far as I can get with my knowledge, could someone with more insight on the inner workings of GTK comment on what might be going on here? If needed the relevant parts of the GTK UI are in http://vim.svn.sourceforge.net/viewvc/vim/vim7/src/gui_gtk.c?view=markup -- Guido Berhoerster ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Re: Finalize a working application
Since i discovered everything and the automake steps now just work everything should be fine, but ...

invisible mouse cursor
Hi all, I am looking for a way to make the mouse cursor invisible for the whole application.

They are being created in the button-clicked event of other windows.

I have no idea. the FileChooser only job is to read the file to get the
contents; I would expect to see a lot of read() operations.
the only time when a gtk+ application writes to the recently used files
storage and it's not calling the GtkRecentManager API directly is when
the gtk+ main loop level reaches 0 - which is to say after the first
gtk_main() call in the whole application returns (this is needed to
ensure that the file is not left in an inconsistent state); all other
writes are definitely explicit. I seriously doubt that vim spins the
main loop and the stops it at every key press - it would be quite
insane.
I wrote both the RecentManager and the FileChooser recently used files
list support, so I'm at loss here as much as you.
ciao,
Emmanuele.

Using PCL with Gtk+
Hi. I would like to know if anyone here has experience using the Portable Coroutine Library with Gtk+? I find the idea to use it very attractive, as it has both the advantages of threaded code (the flow of the program is direct, without having to save the state in structures passed around to signal handlers and callbacks) and non-threaded code (I can avoid all locking issues, and it is always safe to call Gtk+ functions (and OpenGL functions too). Unfortunately, PCL does not seem to be widely used, and I fear there may be some annoying bugs in it. Therefore any information would be helpful.

resize-end event
Hi, I rely on configure-event to detect changes in the size of a widget. With solid resizing a stream of configure-events is produced, as the widget continuously changes size, while with rectangle resizing a single event is produced when the new size is chosen.

Encoding problem in Gtk2::Ex::PodViewer
Hi all,
using the PodViewer widget to display help, I have an encoding problem: I
cannot get the widget to correctly display utf8 text.
I load the pod from a file which is in utf-8, but it is displayed as
iso-8859-1. I also loaded the file into perl first and used
$podviewer-load_string($string) but it didn't help.
If I display the string (loaded from the pod file) in a regular TextBuffer /
TextView, it's correctly displayed; also if I use it as label text or
similar.
### Sample script
use Gtk2 -init;
use Gtk2::Ex::PodViewer;
my $viewer = Gtk2::Ex::PodViewer-new;
# find mypod.pod attached, hope it's still utf8 after mailing it
$viewer-load('mypod.pod');
$viewer-show;
my $window = Gtk2::Window-new;
$window-add($viewer);
$window-show;
Gtk2-main;
###
Any ideas?
Thanks
Ben
