WPF UserControl - cliquez sur l'animation

Question

J'ai créé un fichier WFP UserControl avec du code XAML complexe (converti à partir de SVG). C'est fondamentalement un bouton de fantaisie. Je voudrais créer une animation dans le XAML d'usercontrol pour "déplacer" sa position de 4 pixels vers la droite et vers le bas, pour simuler un clic, et ensuite le faire revenir à son emplacement d'origine. Pour moi, cela ressemble à la première animation que quelqu'un apprendrait dans WPF, mais j'ai du mal à trouver un bon exemple.

J'ai inclus le UserControl si quelqu'un est intéressé.

<UserControl x:Class="PositionButton"

Answer 2

Voir UIElement.RenderTransform. Pour un contrôle de type bouton, une manière typique de faire ceci est de faire une propriété pour votre bouton, quelque chose comme IsPressed, que votre contrôle définit à true dans OnMouseDown, puis de nouveau à false dans OnMouseUp. Ensuite, avoir un style avec un déclencheur sur IsPressed == true, qui définit le RenderTransform pour provoquer un changement - c'est à peu près comment le WPF Button normal le fait.

Dans votre cas, si votre commande a exactement le même comportement que la Button normale, seulement un aspect différent, je ne voudrais pas utiliser effectivement UserControl - Je viens de créer un style personnalisé pour le Button, avec un modèle personnalisé, et utilisez cela (et utilisez Button.IsPressed).
