Hello.
I'm new to Vala and I don't really understand the ownership concept
and especially in relation to string handling. There are some texts I

Is there some tutorial that can help me understand how to work with

Hi Jiri,

Thank you. It works, but it actually doesn't fix it completely. When I

Hello.
Delegates in VAPI are, in fact, bindings to function pointer (which
delegates translate to). So in order to be able to do that, there have
to be those pointers defined in the C header (otherwise it won't
compile with GCC).
If they aren't, you can still define them, but have to use a
:
uchar[] string_to_array (string input, string output_charset = utf-8);
string array_to_string (uchar[] input, string input_charset = utf-8);
which would solve both problems in one go.

Perhaps you wanted return dialog.hide_on_delete (); there? I didn't do
this in a long time, bug if I recall correctly, you need to stop
delete_event by returning

Q1.
What is the recommended way of aborting an
async function so that another invocation can
be made only after the previous one has
stopped, thus ensuring that there is at most
one invocation at any time?
I think I don't fully

Any hope of getting the following replaced
with a better syntax? :-)

Why not simply:
yield;
?
Because 'yield' just stops the method until the

I don't do much Gtk, so I can't help you with this specifically, but I
recommend looking for examples in C if you have at

Hi all
I have a little problem on working with buffer offsets in vala.
In C doing an offset for a char buf[SOME_SIZE]; is easy, but I have
difficulties doing it in vala.
You can simply use the same way you would in C. Cast your buffer to a
pointer

Hello Jiří
Thanks! It works fine with pointers. just like in C. I just there was a
possibility to avoid them in vala because I have to manage them

Thanks for reply!
Hmm... I thought all vala strings are handled as utf-8. So I casted the
buffer just like this:
print(%s\n,(string)buffer);
What would you do ?

From what you're saying it looks like a problem in your terminal
