Re: Changing font of GtkSourceView changes font of GtkSourceMap
I haven't played with the FontMap but was thinking of going the route of using CSS. That, in itself, is a bit of a hassle as I can't seem to find a way to convert a PangoFontDescription to CSS but there are some patches that I found online that should help.

Re: Re: Changing font of GtkSourceView changes font of GtkSourceMap
So, to close the loop...
I filed the following bug:
https://gitlab.gnome.org/GNOME/gtksourceview/issues/41, which promptly
got close as "expected behavior". Apparently, you'd either have to use
CSS or install a new font map for the GtkSourceMap.

Re: Changing font of GtkSourceView changes font of GtkSourceMap
Thanks for the example.
I modified it to illustrate the behavior:
import gi
gi.require_version('GtkSource', '3.0')
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, GtkSource, GObject, Pango
def set_font(button, view, map, tag):
font_name = button.get_font_name()
font = Pango.font_description_from_string(font_name)
map_font = font.copy()
map_font.set_size(1*Pango.SCALE)
tag.set_property("font-desc", font)
buffer = view.get_buffer()
buffer.apply_tag(tag, buffer.get_start_iter(), buffer.get_end_iter())
map.set_property("font-desc", map_font)
class GUI:
def __init__(self):
GObject.type_register(GtkSource.View)
window = Gtk.Window()
window.connect('destroy', self.on_window_destroy)
box = Gtk.VBox()
window.add(box)
fontchooser = Gtk.FontButton()
box.pack_start(fontchooser, False, True, 0)
pane = Gtk.Paned(orientation=Gtk.Orientation.HORIZONTAL)
box.pack_start(pane, True, True, 0)
s_view = GtkSource.View()
buffer = s_view.get_buffer()
with open("/usr/share/doc/glade/README", 'r') as fd:
buffer.set_text(fd.read())
tag = buffer.create_tag("buffer-font")
pane.pack1(s_view, True, False)
s_map = GtkSource.Map()
s_map.set_view(s_view)
pane.pack2(s_map, True, False)
fontchooser.connect("font-set", set_font, s_view, s_map, tag)
window.show_all()
def on_window_destroy(self, window):
Gtk.main_quit()
if __name__ == "__main__":
app = GUI()
Gtk.main()
Give it try and change the font of the view. You'll see that the font
of the map changes to the same font as the view, including *the same
size*.
Thank you.

Scrolling to a line in GtkTextView
Hi,
In my application, I would like to have a GtkTextView be scrolled to a
particular line after the GtkTextBuffer is loaded.
According to the documentation, I can use gtk_text_view_scroll_to_mark() in
order to reliably scroll to the desired line after the line height
computation has been completed. In practice that doesn't work reliably.
Below is the code snippet that I am using:
while (delay++ < 100)
g_main_context_iteration(NULL, FALSE);
debug("Scrolling to line: %lu", lineno);
gtk_text_buffer_get_iter_at_line(GTK_TEXT_BUFFER(priv->sourceBuf),
, (gint)(lineno - 1));
debug("Line: %d, offset: %d", gtk_text_iter_get_line(),
gtk_text_iter_get_offset());
gtk_text_buffer_place_cursor(GTK_TEXT_BUFFER(priv->sourceBuf), );
mark = gtk_text_buffer_get_mark(GTK_TEXT_BUFFER(priv->sourceBuf),
"result-view-search");
gtk_text_buffer_move_mark(GTK_TEXT_BUFFER(priv->sourceBuf), mark,
);
gtk_text_view_scroll_to_mark(GTK_TEXT_VIEW(priv->sourceView), mark, 0.0,
TRUE, 0.0, 0.5);
What I am noticing is that the reliability of this highly depends on the
line number to which I want to scroll and the length of the busy loop in
the beginning - the higher the line number, the longer the busy loop needs
to be in order to reliably scroll to that line.
If the busy loop is not long enough, the text view does scroll but not the
correct line.
What is the proper way to correctly and reliably scroll a GtkTextView to a
certain line?
Thank you,
Mitko

According to the documentation, the View and the Map should be using the same font but with the Map using a font size of 1pt. To me this implies that when I change the font of the TextBuffer of the View using tags, I can copy the PangoFontDescription to a new object, change the font size to 1pt and set the new PangoFontDescription as the "font-desc" property of the Map. In practice, however, the Map always has the exact same font size as the View. No matter what I do, I can't seem to change the font size of the Map to 1pt, unless I change the font size of the View to 1pt, as well.

GtkTreeRowReference and Drag-and-Drop
I've implemented a treeview in my application, which has drag-and-drop enabled to allow re-ordering of the rows. To support tree model updates while the user is performing dnd operations, I also have GtkTreeRowReferences for each row in the model (the model will not have too many rows). However, when I move a row during model update, the tree row reference for that row become invalid after the row-deleted signal handler is processed. What is strange is that, according to the documentation, it seem that this is exactly what GtkTreeRowReference is supposed to handle. Shouldn't the reference be updated to point to the new row? Why would the reference become invalid if I've *moved* the model row instead of deleted it? The row still exists just at a different place. Can someone please clarify this?

Re: State actions and Glade
Hi,
Thank you for your reply. I am not sure what you mean by "GtkToolbar

action names get automatically linked to the actions that I've defined in
the my GActionEntry array. The only thing that does not work are the Radio
button actions.

State actions and Glade
I am trying to write an application using Glade where the tool bar contains
a set of radio tool buttons. Those radio tool buttons should not perform an
action when activated but rather just change the associated action's state.
For that I've set the 'Action Name' property for the tool buttons in Glade
as 'win.radio-state(0)' and 'win.radio-state(1)'.
Since the only thing that I am after is the action's state, I don't even
need a 'chage_state' handler in the action definition. Therefore, the
GActionEntry for the radio buttons is defined as:
{"radio-state", NULL, "i", "0", NULL}
However, no matter what I do, the tool radio buttons are never 'sensitive'
and I can never click on them.
How should I be using state actions with Glade? It seems that I am doing
things as described by https://wiki.gnome.org/HowDoI/GAction but it still
does not work.
Thank you for your help.
