This is not a Balsa issue, but probably some underlying gtk icon issue. The
icons for adjusting the relative position of panes GtkPaned ?) have the
vertical and horizontal icons swapped. For example, I use the default layout
with preview pane. If I try to adjust the relative height of the message list
and preview pane, the icon for grabbing the separator is two vertical bars with
arrows to the right and left. If I try to adjust the relative size of the
mailbox list (left) and the message list and preview pane (right) the icon is
two horizontal bars and arrows pointing up and down. I see the same problem in
the gentoo file browser (application by that name, having nothing to do with
the Gentoo distro.) I've hunted through every gtk3 them and icon I can find,
and cannot find those icons. Does anyone know where they come from? Are they
build into gtk3? It's not really imporant, but it's starting to drive me crazy
that I can't find where they are coming from.
Thanks for any suggestions.
The relevant code in gtkpaned.c may be:
if (gtk_widget_is_sensitive (widget))
cursor = gdk_cursor_new_from_name (gtk_widget_get_display (widget),
priv->orientation ==
GTK_ORIENTATION_HORIZONTAL
? "col-resize" : "row-resize");
else
cursor = NULL;
gdk_window_set_cursor (priv->handle, cursor);
The doc[1] shows all the available cursors, and "col-resize" and "row-resize"
are what you'd expect. It states that:
[gdk_cursor_new_from_name] Creates a new cursor by looking up name in the
current cursor theme.
so the fault may lie in the "current cursor theme", whatever that is! On my Fedora box,
/usr/share/icons/Adwaita/cursors/col-resize is a symlink to
/usr/share/icons/Adwaita/cursors/sb_h_double_arrow, which "file" declares to be an "X11
cursor", and which is indeed a double-ended horizontal arrow. You could try looking for some file with
col[-_]resize in its name--that's the best I can suggest!
