Hier mal ein kleines Beispiel, wie man den Cursor auf Wait stellen kann, wenn man eine Methode hat, die sehr rechenintensiv ist
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;
namespace App.cursor
{
public class OverrideCursor : IDisposable
{
static Stack<Cursor> s_Stack = new Stack<Cursor>();
public OverrideCursor(Cursor changeToCursor)
{
s_Stack.Push(changeToCursor);
if (Mouse.OverrideCursor != changeToCursor)
Mouse.OverrideCursor = changeToCursor;
}
public void Dispose()
{
s_Stack.Pop();
Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;
if (cursor != Mouse.OverrideCursor)
Mouse.OverrideCursor = cursor;
}
}
}Code-Sprache: HTML, XML (xml)
using (new OverrideCursor(Cursors.Wait))
{
// eine Action
}Code-Sprache: JavaScript (javascript)
