[Vala] Detailed signals
Hi: How can I connect to a detailed signal, eg: 'changed::x' as you can see in the GSettings Devhelp code: -sample--- The "changed" signal void user_function (GSettings *settings, gchar *key, gpointer user_data) : Run Last / Has Details The "changed" signal is emitted when a key has potentially changed. You should call one of the g_settings_get() calls to check the new value. This signal supports detailed connections. You can connect to the detailed signal "changed::x" in order to only receive callbacks when key "x" changes. settings : the object on which the signal was emitted key : the name of the key that changed user_data : user data set when the signal handler was connected. -sample--- I tried the obvious object.changed::x.connect(...); and clearly didn't work. So help please... Thxs ___ vala-list mailing list vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list

[Vala] GIO get_contens
Hello, I was looking the basic gio sample there a file is read line by line. Exist some way to read the without using a while loop? php have a funtion get_contens that is what I need.

[Vala] Dbus, connecting a signal to an async method...
Hello, I've a situation like the one in the example that I've attached
here, where I need to make an asynchronous call to a method from a dbus
signal callback function; to perform that I need to use the yield
modifier, and so I need the callback function method should be async.
Now, when I connect the async method to the dbus interface with
somethink like:
session_proxy = (FreeDesktopDBus) connection.get_object
(FreeDesktopDBus.UNIQUE_NAME,
FreeDesktopDBus.OBJECT_PATH,
FreeDesktopDBus.INTERFACE_NAME);
session_proxy.name_acquired.connect (this.name_acquired);
Where name_acquired is defined as:
private async void name_acquired(FreeDesktopDBus sender, string name) {
}
I get an error:
Cannot convert from `Test.name_acquired' to
`FreeDesktopDBus.name_acquired
As a workaround I added two sync signal methods to the dbus interface,
but not using async calls is not a good think here...
Other ways? Thanks!
Bye.
PS: I'm using dbus-glib since the project I'm working on, uses it and I
can't change that.

[Vala] char variables problem
Hi guys.
what is the problem with this code?
public void main(){
char ch1 = 'a';
char? ch2 = 'b';
stdout.printf("%c\n", ch1);
stdout.printf("%c\n", ch2);
stdout.printf("%s\n", ch1.to_string());
stdout.printf("%s\n", ch2.to_string());
}
when I assign a value to ch1 and ch2, they remain empty and nothing is
printed in output.
Why...
