Hello,
I am making a GTK3 application with GtkTreeView listing.
The simple listing will show country flags + names and number of
radio-channels (to later choose from).
I want to show a button or icon in a column (in the cell) when the row has
been selected.
Otherwise the cell should be empty

Have you tried a GtkListBox for this? You can probably setup a scrolling window

Is that not property of your theme?
I have no separator between columns.

Hello everybody,
I am trying to develop a small music manager using GTK+ and GStreamer.
However, I am currently unable to display the stream information (like
artist, title, album, etc...) on the GtkTreeView.
I do not know if anyone here has any experience developing software like
this. But the
ed to achieve that with
a timeout. A huge lot of work
to achieve something trivial. It's so unnatural that I suspect there is a more
elegant way not known to me
who am still a novice in GTK+.

Hi:
I have a situation where I need to verify data before allowing a row change in
a GtkTreeView. Essentially:
1. User requests a row change through a keyboard or a mouse;
2. Check if data in the current row has been edited without be saved, or even
is complete
and valid, and prompt the user
GtkTreeViewColumn implement GtkCellLayout interface, so you can use
GtkCellLayout methods to packing more than one GtkCellRenderer.

Hi everyone.
As the attachment picture shows, I wanna append a column group "Position" to
the GtkTreeView.
The column group "Position" has 3 GtkTreeViewColumn members: "Pan", "Tilt"
and "Time".
Under the big header button "Position", th
te it with this when I have the time.

The signal that is emitted when cursor moves is
GtkTreeView::cursor-changed. GtkTreeView::move-cursor is action signal
that can be safely emitted by application.

Oh, I had the impression that the move-cursor signal was emitted by
the TreeView when the cursor was moved. I didn't know it was the other
way around. I've already managed to get it working after reading your
earlier email, but I might rewrite it with this when I have the time.
Thanks for the point

Alternatively, you can also emit GtkTreeView::move-cursor signal with
proper arguments, but gett
gtk_tree_view_row_expanded looks like it should do the trick...
thanks! I can't believe I missed that in the docs.
Nonetheless, it feels a bit unnatural to replicate in my code behavior
