Thanks you for your replies!
But the bug is still there.
I have given a wrong example for this bug(since it works).
The good example for this bug, is:
public class Foo : GLib.Object {
public virtual void func() {
}
internal static void bug () {
new Bar ();
}
}
public class Bar : Foo {
public override void func() {
}
}
Valac(0.16.1) gives:
$ valac main.vala
main.vala:11.2-11.26: error: Bar.func: no suitable method found to override
public override void func() {
^^^^^^^^^^^^^^^^^^^^^^^^^
Compilation failed: 1 error(s), 0 warning(s)
When there's some method inside classes(e.g. "bug"), no matter if it's static
or not,
that calls Bar contractor, valac gives this error.
However, if "bug" method is outside of Foo class blocks, valac compiles fine.
I have report this bug in GNOME Bugzilla:
https://bugzilla.gnome.org/show_bug.cgi?id=690335
Hope you'll fix this bug in next releases.
Yours

Subject: Re: [Vala] Defining new virtual signal is possible, but overring it
isn't.
You can try code below as solution/workaround.
class Foo : GLib.Object
{
public virtual signal void func()
{
message("Foo");
}
}
class Bar : Foo
{
public override void func()
{
message("Bar");
}
}
int main()
{
Foo foo = new Bar();
foo.func.connect(() => { message("Main"); });
foo.func();
return 0;
}
