C# WPF - Plus j'appuie sur un bouton, plus vite sera compté

Question

Je viens de "construire" un bouton Numérique Haut Bas. Maintenant j'ai une question, je voudrais que si j'appuie sur le bouton plus longtemps les presses sont comptées plus vite. Mais seulement après 1-2 secondes. Ainsi que le bouton Numeric Up Down normal. Si vous avez cliqué sur le bouton, plus vite il a été compté.

Comment faire cela?

Vous pouvez ajouter une minuterie et sur mousebutton vers le bas, démarrer le minuteur, dans la mousebutton jusqu'à, arrêtez. La minuterie, si le temps écoulé depuis que la souris est enfoncée est> 2s, peut augmenter de +1 à un incrément, de sorte que le compte augmente par incrémentation. Chaque itération augmente de plus en plus vite, ou utilise simplement la minuterie pour + 1 si < 2s et +5 ou quelque chose après 2s .. choix sont à vous
