wpf - Hide cursor when idle -


in wpf app, want hide cursor when hasn't moved number of seconds. if moved, want show again. ideas?

you use mousemove event :

tested code:

mytimer = new timer(3000); mytimer.autoreset = false; mytimer.elapsed += delegate { mouseext.safeoverridecursor(cursors.none); }; //hide cursor  private void myview_mousemove(object sender, mouseeventargs e) {      mytimer.stop();      mouse.overridecursor = null; //show cursor      mytimer.start(); }

this helper dispatching call override cursor:

public static class mouseext {     public static void safeoverridecursor(cursor cursor)     {         application.current.dispatcher.invoke(new action(() =>         {             mouse.overridecursor = cursor;         }));     } }

when timer elapses cursor hidden. when moved reappears , timer reset.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
