Thanks a bunch, Luca.
Passing parameters through closures does work using GLib.Idle.add() instead of
Gdk.threads_add_idle().
That helped, thanks again.
Best,

Use Idle.add.

I'm trying to pass a parameter to a function that I call through
threads_add_idle().
But threads_add_idle() obviously accepts only a SourceFunc.
I can't pick up the data from a global variable. So I tried using closures from
where I'd pass the needed parameter:
private void ThreadedFunc(uint 8 byte)
{
Gdk.threads_add_idle(()=>
{
GuiWorker(byte);
return false;
});
}
But then the class of GuiWorker is not instantiated, so I get an assertion
during runtime (self != null). If I don't try to pass the parameter and just
pass 'GuiWorker' to threads_add_idle() directly (given 'GuiWorker' doesn't take
any params then), then the instance does exist.
Before that, when I used the deprecated methods Gdk.threads_enter() and
Gdk.threads_leave(), I could help myself by doing whatever I wanted in between.
But how can I work with threads_add_idle() now? The vala bindings omit its
second parameter 'data', so I'd be glad if you could tell me how do it 'the
right way'.
Thanks a bunch.
