Comment développer une fenêtre personnalisée qui aura toutes les propriétés de la fenêtre générale en utilisant WPF

Question

I am going to develop my own window where I'll have my own Caption Buttons 

(réduire, agrandir, restaurer et fermer) et toutes les propriétés liées à ces boutons et peut ajouter une commande à la position du titre de la fenêtre.

me suggérer la manière dont je vais continuer pour elle ...... s'il vous plaît

Merci à l'avance

Answer 1

Ma suggestion est de ne pas le faire. Ce n'est pas nécessaire dans WPF.

Il suffit de changer le modèle de fenêtre et vous obtiendrez ce que vous demandez.

Vous avez besoin des 3 images pour les min/max/boutons normaux/fermeture (référencés dans les images Images/min.png, Images/max.png, Images/normal.png, Images/fermer. png).

Cette ressource devrait être disponible au niveau mondial. Vous pouvez faire référence en XAML comme ceci:

...

Dans mon projet, le concepteur avait tendance à étouffer cette référence (peut-être parce qu'il était un projet WinForms avec un corps principal composé de WPF éléments). À cause de cela, nous avons dû définir le style par programmation, dans le code-behind, dans le constructeur de la fenêtre:

Style = (Style) FindResource (Constants.DEFAULT_WINDOW_STYLE);

avec une déclaration constante avec la valeur "WindowStyle".

Voici le résultat (je présente mes excuses pour le contenu vide, mais il est confidentiel):

Je n'ai pas dit qu'il était assez ...
